3 CasparCG 2.1.0 Next (w.r.t 2.1.0 Beta 1)
\r
4 ========================================
\r
9 o Fail early with clear error message if configured paths are not
\r
11 o Added backwards compatibility (with deprecation warning) for using
\r
12 thumbnails-path instead of thumbnail-path in casparcg.config.
\r
13 o Suppress the logging of full path names in stack traces so that only the
\r
14 relative path within the source tree is visible.
\r
15 o General stability improvements.
\r
16 o Native thread id is now logged in Linux as well. Finally they are mappable
\r
17 against INFO THREADS, ps and top.
\r
18 o Created automatically generated build number, so that it is easier to see
\r
19 whether a build is newer or older than an other.
\r
20 o Changed configuration element mipmapping_default_on to mipmapping-default-on
\r
21 for consistency with the rest of the configuration (Jesper Stærkær).
\r
22 o Handle stdin EOF as EXIT.
\r
23 o Added support for RESTART in Linux startup script run.sh.
\r
24 o Copy casparcg_auto_restart.bat into Windows releases.
\r
25 o Fixed bug with thumbnail generation when there are .-files in the media
\r
27 o Removed CMake platform specification in Linux build script
\r
28 (Krzysztof Pyrkosz).
\r
29 o Build script for building FFmpeg for Linux now part of the repository.
\r
30 Contributions during development (not w.r.t 2.1.0 Beta 1):
\r
31 + Fix ffmpeg build dependencies on clean ubuntu desktop amd64 14.04.3 or
\r
32 higher (Walter Sonius).
\r
33 o Added support for video modes 2160p5000, 2160p5994 and 2160p6000
\r
34 (Antonio Ruano Cuesta).
\r
40 + Fixed long overdue bug where HD material was always recorded using the
\r
41 BT.601 color matrix instead of the BT.709 color matrix. RGB codecs like
\r
42 qtrle was never affected but all the YCbCr based codecs were.
\r
43 + Fixed bug in parsing of paths containing -.
\r
44 o DeckLink consumer:
\r
45 + Fixed possible dead-lock in frame queue.
\r
51 + Increased the max number of frames that audio/video can be badly
\r
52 interleaved with (Dimitry Ishenko).
\r
53 + Fixed bug where decoders sometimes requires more than one video packet to
\r
54 decode the first frame.
\r
55 + Added support for IN and OUT parameters (Dimitry Ishenko).
\r
56 + Added DV/HDV video device support under Linux (Walter Sonius).
\r
57 o Framerate producer:
\r
58 + Fixed bug when INFO was used on a not yet playing framerate producer.
\r
60 + Fixed bug where only URL:s with . in them where recognized.
\r
62 + Added LENGTH parameter to allow for queueing with LOADBG AUTO.
\r
64 + Fixed serious bug where a circular reference of layer producers caused a
\r
65 stack overflow and server crash.
\r
67 + Added abs() function to expression language.
\r
72 o Fixed bug in the contrast/saturation/brightness code where the wrong luma
\r
73 coefficients was used.
\r
74 o Rewrote the chroma key code to support variable hue, instead of fixed green
\r
75 or blue. Threshold setting was removed in favour of separate hue width,
\r
76 minimum saturation and minimum brightness constraints. Also a much more
\r
77 effective spill suppression method was implemented.
\r
78 o Fixed bug where glReadPixels() was done from the last drawn to texture
\r
79 instead of always from the target texture. This means that for example a
\r
80 MIXER KEYER layer without a layer above to key, as well as a separate alpha
\r
81 file with MIXER OPACITY 0 now works as expected.
\r
86 o INFO PATHS now adds all the path elements even if they are using the default
\r
88 o MIXER CHROMA syntax deprecated (still supported) in favour of the more
\r
89 advanced syntax required by the rewritten chroma key code.
\r
90 o Added special command REQ that can be prepended before any command to
\r
91 identify the response with a client specified request id, allowing a client
\r
92 to know exactly what asynchronous response matched a specific request.
\r
93 o Added support for listing contents of a specific directory for CLS, TLS,
\r
94 DATA LIST and THUMBNAIL LIST.
\r
95 o Fixed bug where CINF only returned the first match.
\r
99 CasparCG 2.1.0 Beta 1 (w.r.t 2.0.7 Stable)
\r
100 ==========================================
\r
107 + Moved to CMake build system for better platform independence.
\r
108 + Contributions before build system switch (not w.r.t 2.0.7 Stable):
\r
109 + gitrev.bat adaptions for 2.1 (Thomas Kaltz III).
\r
110 + Thanks to our already heavy use of the pimpl idiom, abstracting platform
\r
111 specifics was easily done by having different versions of the .cpp files
\r
112 included in the build depending on target platform. No #ifdef necessary,
\r
113 except for in header only platform specific code.
\r
114 + Flash, Bluefish and NewTek modules are not ported to the Linux build.
\r
115 + Contributions during development (not w.r.t 2.0.7 Stable):
\r
116 + Fixed compilation problems in Linux build (Dimitry Ishenko).
\r
117 + Fixed compilation problem in GCC 5 (Krzysztof Pyrkosz).
\r
118 + Fixed thumbnail image saving on Linux (Krzysztof Pyrkosz).
\r
119 + Fixed compilation problem in PSD module (Krzysztof Pyrkosz).
\r
120 o Major code refactoring:
\r
121 + Mixer abstraction so different implementations can be created. Currently
\r
122 CPU mixer and GPU mixer (previously the usage of the GPU was mandatory)
\r
124 + Flattened folder structure for easier inclusion of header files.
\r
125 + Many classes renamed to better describe the abstractions they provide.
\r
126 + Sink parameters usually taken by value and moved into place instead of
\r
127 taken by const reference as previously done.
\r
128 + Old Windows specific AsyncEventServer class has been replaced by platform
\r
129 independent implementation based on Boost.Asio.
\r
130 + Pimpl classes are now stack allocated with internal shared_ptr to
\r
131 implementation, instead of both handle and body being dynamically
\r
132 allocated. This means that objects are now often passed by value instead
\r
133 of via safe_ptr/shared_ptr, because they are internally reference counted.
\r
134 + Protocol strategies are now easier to implement correctly, because of
\r
135 separation of state between different client connections.
\r
136 + Complete AMCP command refactoring.
\r
137 + On-line help system that forces the developer to document AMCP commands,
\r
138 producer syntaxes and consumer syntaxes making the documentation coupled
\r
139 to the code, which is great.
\r
140 + Added missing help for VERSION command (Jesper Stærkær).
\r
141 + Upgraded Windows build to target Visual Studio 2015 making it possible to
\r
142 use the C++11 features also supported by GCC 4.8 which is targeted on
\r
144 + Fixed compilation problems in Visual Studio 2015 Update 1
\r
146 + Created abstraction of the different forms of templates (flash, html, psd
\r
147 and scene). Each module registers itself as a CG producer provides. All CG
\r
148 commands transparently works with all of them.
\r
149 + Audio mixer now uses double samples instead of float samples to fully
\r
150 accommodate all int32 samples.
\r
151 + Reduced coupling between core and modules (and modules and modules):
\r
152 + Modules can register system info providers to contribute to INFO SYSTEM.
\r
153 + XML configuration factories for adding support for new consumer elements
\r
154 in casparcg.config.
\r
155 + Server startup hooks can be registered (used by HTML producer to fork
\r
157 + Version providers can contribute content to the VERSION command.
\r
158 o Refactored multichannel audio support to use FFmpeg's PAN filter and
\r
159 simplified the configuration a lot.
\r
160 o Upgraded most third party libraries we depend on.
\r
161 o Some unit tests have been created.
\r
162 o Renamed README.txt to README, CHANGES.txt to CHANGELOG and LICENSE.txt to
\r
164 o Created README.md for github front page in addition to README which is
\r
165 distributed with builds.
\r
166 o README file updates (Jonas Hummelstrand).
\r
167 o Created BUILDING file describing how to build the server on Windows and
\r
170 + Now also sent over OSC.
\r
171 + Diag window is now scrollable and without squeezing of graphs.
\r
172 + Contextual information such as video channel and video layer now included
\r
175 + Implemented a TCP server, simply sending every log line to each connected
\r
176 client. Default port is 3250.
\r
177 + Changed default log level to info and moved debug statements that are
\r
178 interesting in a production system to info.
\r
179 + Try to not log full stack traces when user error is the cause. Stacktraces
\r
180 should ideally only be logged when a system error or a programming error
\r
182 + More contextual information about an error added to exceptions. An example
\r
183 of this is that XML configuration errors now cause the XPath of the error
\r
185 + Improved the readability of the log format.
\r
186 + Added optional calltrace.log for logging method calls. Allows for trace
\r
187 logging to be enabled while calltracing is disabled etc.
\r
192 o Improved message formatting performance.
\r
193 o Added possibility to disable sending OSC to connected AMCP clients.
\r
194 o Fixed inconsistent element name predefined_client to predefined-client in
\r
195 casparcg.config (Krzysztof Pyrkosz).
\r
200 o System audio consumer:
\r
201 + Pushes data to openal instead of being callbacked by SFML when data is
\r
203 + Added possibility to specify the expected delay in the sound card. Might
\r
204 help get better consumer synchronization.
\r
206 + Added mouse interaction support, usable by the producers running on the
\r
209 + Replaced by Streaming Consumer after it was adapted to support everything
\r
210 that FFmpeg Consumer did.
\r
211 + Added support for recording all audio channels into separate mono audio
\r
213 + Now sends recording progress via OSC.
\r
216 + Allows the pace of a channel to follow another channel. This is useful for
\r
217 virtual "precomp" channels without a DeckLink consumer to pace it.
\r
218 o DeckLink consumer:
\r
219 + Added workaround for timescale bug found in Decklink SDK 10.7.
\r
220 + Now ScheduledFrameCompleted is no longer only used for video scheduling
\r
221 but for audio as well, simplifying the code a lot.
\r
223 + No longer provides sync to the video channel.
\r
224 + Supports NewTek NDI out of the box just by upgrading the
\r
225 Processing.AirSend library.
\r
232 + Utilizes CasparCG concepts such as producers, mixer transforms and uses
\r
233 them in a nested way to form infinite number of sub layers. Think movie
\r
235 + A scene consists of variables, layers, timelines and marks (intro and
\r
236 outro for example).
\r
237 + Mostly for use by other producers but comes with a XML based producer that
\r
238 is a registered CG producer and shows up in TLS.
\r
239 + Enables frame accurate compositions and animations.
\r
240 + Has a powerful variable binding system (think expressions in After Effects
\r
241 or JavaFX Bindings).
\r
244 + Parses PSD files and sets up a scene for the Scene producer to display.
\r
245 + Text layers based on CG parameters.
\r
246 + Supports Photoshop timeline.
\r
247 + Uses Photoshop comment key-frames to describe where intro and outro (CG
\r
248 PLAY and CG STOP) should be in the timeline.
\r
249 + Shows up as regular templates in TLS.
\r
252 + Renders text using FreeType library.
\r
253 + Is used by the PSD producer for dynamic text layers.
\r
254 o Image scroll producer:
\r
255 + Speed can be changed while running using a CALL. The speed change can be
\r
257 + Added support for an absolute end time so that the duration is calculated
\r
258 based on when PLAY is called for shows when an exact end time is
\r
261 + Fixed bug where too large (OpenGL limit) images were accepted, causing
\r
262 problems during thumbnail generation.
\r
263 o Framerate producer:
\r
265 + Wraps a producer with one framerate and converts it to another. It is not
\r
266 usable on its own but is utilized in the FFmpeg producer and the DeckLink
\r
268 + Supports different interpolation algorithms. Currently a no-op
\r
269 drop-and-repeat mode and a two different frame blending modes.
\r
270 + It also supports changing the speed on demand with tweening support.
\r
272 + Supports decoding all audio streams from a clip. Useful with .mxf files
\r
273 which usually have separate mono streams for every audio channel.
\r
274 + No longer do framerate conversion (half or double), but delegates that
\r
275 task to the Framerate producer.
\r
276 + Added support for v4l2 devices.
\r
277 + Added relative and "from end" seeking (Dimitry Ishenko).
\r
278 + Contributions during development (not w.r.t 2.0.7 Stable):
\r
279 + Fixed 100% CPU problem on clip EOF (Peter Keuter, Robert Nagy).
\r
280 + Constrained SEEK within the length of a clip (Dimitry Ishenko).
\r
281 + Fixed a regular expression (Dimitry Ishenko).
\r
282 o DeckLink producer:
\r
283 + No longer do framerate conversion (half or double), but delegates that
\r
284 task to the Framerate producer.
\r
286 + Added possibility to delay frames routed from a layer or a channel.
\r
288 + Disabled web security in HTML Producer (Robert Nagy).
\r
289 + Reimplemented requestAnimationFrame handling in Javascript instead of C++.
\r
290 + Implemented cancelAnimationFrame.
\r
291 + Increased animation smoothness in HTML Producer with interlaced video
\r
293 + Added remote debugging support.
\r
294 + Added mouse interaction support by utilizing the Screen consumer's new
\r
295 interaction support.
\r
297 + Contributions during development (not w.r.t 2.0.7 Stable):
\r
298 + Workaround for flickering with high CPU usage and CPU accelerator
\r
304 o TLS has a new column for "template type" for clients that want to
\r
305 differentiate between html and flash for example.
\r
306 o SET CHANNEL_LAYOUT added to be able to change the audio channel layout of a
\r
307 video channel at runtime.
\r
308 o HELP command added for accessing the new on-line help system.
\r
309 o FLS added to list the fonts usable by the Text producer.
\r
310 o LOCK command added for controlling/gaining exclusive access to a video
\r
312 o LOG CATEGORY command added to enable/disable the new log categories.
\r
313 o SWAP command now optionally supports swapping the transforms as well as the
\r
315 o VERSION command can now provide CEF version.
\r
319 CasparCG Server 2.0.7 Stable (as compared to CasparCG Server 2.0.7 Beta 2)
\r
320 ==========================================================================
\r
325 o Added support for using a different configuration file at startup than the
\r
326 default casparcg.config by simply adding the name of the file to use as the
\r
327 first command line argument to casparcg.exe.
\r
328 o Upgraded FFmpeg to latest stable.
\r
329 o Created build script.
\r
330 o Fixed bug where both layer_producer and channel_producer display:s and
\r
331 empty/late first frame when the producer is called before the consumer in
\r
332 the other end has received the first frame.
\r
333 o Added rudimentary support for audio for layer_producer and channel_producer.
\r
334 o Upgraded DeckLink SDK to 10.1.4, bringing new 2K and 4K DCI video modes. New
\r
335 template hosts also available for those modes.
\r
336 o General bug fixes (mostly memory and resource leaks, some serious).
\r
337 o Updated Boost to version 1.57
\r
338 o Frontend no longer maintained and therefore not included in the release.
\r
343 o Added support for rotation.
\r
344 o Added support for changing the anchor point around which fill_translation,
\r
345 fill_scale and rotation will be done from.
\r
346 o Added support for perspective correct corner pinning.
\r
347 o Added support for mipmapped textures with anisotropic filtering for
\r
348 increased downscaling quality. Whether to enable by default can be
\r
349 configured in casparcg.config.
\r
350 o Added support for cropping a layer. Not the same as clipping.
\r
355 o Added RESUME command to complement PAUSE. (Peter Keuter)
\r
356 o To support the new mixer features the following commands has been added:
\r
358 + MIXER ANCHOR -- will return or modify the anchor point for a layer
\r
359 (default is 0 0 for backwards compatibility). Example:
\r
360 MIXER 1-10 ANCHOR 0.5 0.5
\r
361 ...for changing the anchor to the middle of the layer
\r
362 (a MIXER 1-10 FILL 0.5 0.5 1 1 will be necessary to place the layer at the
\r
363 same place on screen as it was before).
\r
365 + MIXER ROTATION -- will return or modify the angle of which a layer is
\r
366 rotated by (clockwise degrees) around the point specified by ANCHOR.
\r
368 + MIXER PERSPECTIVE -- will return or modify the corners of the perspective
\r
369 transformation of a layer. One X Y pair for each corner (order upper left,
\r
370 upper right, lower right and lower left). Example:
\r
371 MIXER 1-10 PERSPECTIVE 0.4 0.4 0.6 0.4 1 1 0 1
\r
373 + MIXER MIPMAP -- will return or modify whether to enable mipmapping of
\r
374 textures produced on a layer. Only frames produced after a change will be
\r
375 affected. So for example image_producer will not be affected while the
\r
376 image is displayed.
\r
378 + MIXER CROP -- will return or modify how textures on a layer will be
\r
379 cropped. One X Y pair each for the upper left corner and for the lower
\r
382 o Added INFO QUEUES command for debugging AMCP command queues. Useful for
\r
383 debugging command queue overflows, where a command is deadlocked. Hopefully
\r
384 always accessible via console, even though the TCP command queue may be
\r
386 o Added GL command:
\r
387 - GL INFO prints information about device buffers and host buffers.
\r
388 - GL GC garbage collects pooled but unused GL resources.
\r
389 o Added INFO THREADS command listing the known threads and their descriptive
\r
390 names. Can be matched against the thread id column of log entries.
\r
395 o Removed blocking_decklink_consumer. It was more like an experiment at best
\r
396 and its usefulness was questionable.
\r
397 o Added a 10 second time-out for consumer sends, to detect/recover from
\r
399 o Some consumers which are usually added and removed during playout (for
\r
400 example ffmpeg_consumer, streaming_consumer and channel_consumer) no longer
\r
401 affect the presentation time on other consumers. Previously a lag on the SDI
\r
402 output could be seen when adding such consumers.
\r
407 o No longer tries to play all files with a . in their name.
\r
408 (Georgi Chorbadzhiyski)
\r
409 o Reimplemented using CEF3 instead of Berkelium, which enables use of WebGL
\r
410 and more. CEF3 is actively maintained, which Berkelium is not. (Robert Nagy)
\r
411 o Implements a custom version of window.requestAnimationFrame which will
\r
412 follow the pace of the channel, for perfectly smooth animations.
\r
413 o No longer manually interlaces frames, to allow for mixer fill transforms
\r
415 o Now uses CEF3 event loop to avoid 100% CPU core usage.
\r
419 CasparCG Server 2.0.7 Beta 2 (as compared to CasparCG Server 2.0.7 Beta 1)
\r
420 ==========================================================================
\r
425 o Added sending of OSC messages for channel_grid channel in addition to
\r
431 o FFmpeg: Reports correct nb_frames() when using SEEK (Thomas Kaltz III)
\r
432 o Flash: Fixed bug where CG PLAY, CG INVOKE did not work.
\r
437 o channel_consumer: Added support for more than one channel_consumer per
\r
439 o decklink_consumer: Added support for a single instance of the consumer to
\r
440 manage a separate key output for use with DeckLink Duo/Quad cards:
\r
444 <key-device>2</key-device>
\r
445 <keyer>external_separate_device</keyer>
\r
448 ...in the configuration will enable the feature. The value of <key-device />
\r
449 defaults to the value of <device /> + 1.
\r
450 o synchronizing_consumer: Removed in favour of a single decklink_consumer
\r
451 managing both fill and key device.
\r
452 o streaming_consumer: A new implementation of ffmpeg_consumer with added
\r
453 support for streaming and other PTS dependent protocols. Examples:
\r
456 <path>udp://localhost:5004</path>
\r
457 <args>-vcodec libx264 -tune zerolatency -preset ultrafast -crf 25 -format mpegts -vf scale=240:180</args>
\r
460 ...in configuration or:
\r
462 ADD 1 STREAM udp://localhost:5004 -vcodec libx264 -tune zerolatency -preset ultrafast -crf 25 -format mpegts -vf scale=240:180
\r
464 ...via AMCP. (Robert Nagy sponsored by Ericsson Broadcasting Services)
\r
465 o newtek_ivga_consumer: Added support for iVGA consumer to not provide channel
\r
466 sync even though connected. Useful for iVGA clients that downloads as fast
\r
467 as possible instead of in frame-rate pace, like Wirecast. To enable:
\r
470 <provide-sync>false</provide-sync>
\r
473 ...in config to not provide channel sync when connected. The default is
\r
479 o Added support in ADD and REMOVE for a placeholder <CLIENT_IP_ADDRESS> which
\r
480 will resolve to the connected AMCP client's IPV4 address.
\r
481 o Fixed bug where AMCP commands split into multiple TCP packets where not
\r
482 correctly parsed (http://casparcg.com/forum/viewtopic.php?f=3&t=2480)
\r
486 CasparCG Server 2.0.7 Beta 1 (as compared to 2.0.6 Stable)
\r
487 ==========================================================
\r
491 o FFmpeg: Upgraded to master and adapted CasparCG to FFmpeg API changes
\r
492 (Robert Nagy sponsored by SVT)
\r
493 o FFmpeg: Fixed problem with frame count calculation (Thomas Kaltz III)
\r
494 o Fixed broken CG UPDATE.
\r
499 o New HTML producer has been created (Robert Nagy sponsored by Flemish Radio
\r
500 and Television Broadcasting Organization, VRT)
\r
504 CasparCG Server 2.0.6 Stable (as compared to 2.0.4 Stable)
\r
505 ==========================================================
\r
509 o iVGA: Allow for the server to work without Processing.AirSend.x86.dll to
\r
510 prevent a possible GPL violation. It is available as a separate optional
\r
512 o iVGA: Only provide sync to channel while connected, to prevent channel
\r
514 o FFmpeg: Fixed bug during deinterlace-bob-reinterlace where output fields
\r
515 were offset by one field in relation to input fields.
\r
516 o FFmpeg: Fixed bug in ffmpeg_consumer where an access violation occurred
\r
517 during destruction.
\r
518 o FFmpeg: Improved seeking. (Robert Nagy and Thomas Kaltz III)
\r
519 o Frontend: Only writes elements to casparcg.config which overrides a default
\r
520 value to keep the file as compact as possible.
\r
521 o System audio: Patched sfml-audio to work better with oal-consumer and
\r
522 therefore removed PortAudio as the system audio implementation and went back
\r
524 o Flash: Changed so that the initial buffer fill of frames is rendered at a
\r
525 frame-duration pace instead of as fast as possible. Otherwise time based
\r
526 animations render incorrectly. During buffer recovery, a higher paced
\r
527 rendering takes place, but still not as fast as possible, which can cause
\r
528 animations to be somewhat incorrectly rendered. This is the only way though
\r
529 if we want the buffer to be able to recover after depletion.
\r
530 o Fixed race condition during server shutdown.
\r
531 o OSC: outgoing audio levels from the audio mixer for each audio channel is
\r
532 now transmitted (pFS and dBFS). (Thomas Kaltz III)
\r
533 o Stage: Fixed bug where tweened transforms were only ticked when a
\r
534 corresponding layer existed.
\r
535 o Screen consumer: Added borderless option and correct handling of name
\r
536 option. (Thomas Kaltz III)
\r
537 o AMCP: CLS now reports duration and framerate for MOVIE files were
\r
538 information is possible to extract. (Robert Nagy)
\r
539 o Version bump to keep up with CasparCG Client version.
\r
543 CasparCG Server 2.0.4 Stable (as compared to 2.0.4 Beta 1)
\r
544 ==========================================================
\r
548 o Can now open media with file names that only consist of digits.
\r
550 o Miscellaneous stability and performance improvements.
\r
554 o Conditional compilation of chroma key support and straight alpha output
\r
555 support in shader (just like with blend-modes) because of performance impact
\r
556 even when not in use on a layer or on a channel. New <mixer /> element added
\r
557 to configuration for turning on mixer features that not everybody would want
\r
558 to pay for (performance-wise.) blend-modes also moved into this element.
\r
559 o Fixed bug where MIXER LEVELS interpreted arguments in the wrong order, so
\r
560 that gamma was interpreted as max_input and vice versa.
\r
564 o Added support for NewTek iVGA, which enables the use of CasparCG Server
\r
565 fill+key output(s) as input source(s) to a NewTek TriCaster without
\r
566 requiring video card(s) in the CasparCG Server machine, or taking up inputs
\r
567 in the TriCaster. <newtek-ivga /> element in config enables iVGA on a
\r
568 channel. (Robert Nagy sponsored by NewTek)
\r
569 o DeckLink: Created custom decklink allocator to reduce the memory footprint.
\r
570 o Replaced usage of SFML for <system-audio /> with PortAudio, because of
\r
571 problems with SFML since change to static linkage. Also PortAudio seems to
\r
572 give lower latency.
\r
576 o FFmpeg: Added support for arbitrary FFmpeg options/parameters
\r
577 in ffmpeg_producer. (Cambell Prince)
\r
578 o Flash: Flash Player 11.8 now tested and fully supported.
\r
579 o Flash: No longer starts a Flash Player to service CG commands that mean
\r
580 nothing without an already running Flash Player.
\r
581 o Flash: globally serialize initialization and destruction of Flash Players,
\r
582 to avoid race conditions in Flash.
\r
583 o Flash: changed so that the Flash buffer is filled with Flash Player
\r
584 generated content at initialization instead of empty frames.
\r
588 o Performance improvements. (Robert Nagy sponsored by Boffins Technologies)
\r
589 o Never sends old values to OSC receivers. Collects the latest value of each
\r
590 path logged since last UDP send, and sends the new UDP packet (to each
\r
591 subscribing OSC receiver) with the values collected. (Robert Nagy sponsored
\r
592 by Boffins Technologies)
\r
593 o Batches as many OSC messages as possible in an OSC bundle to reduce the
\r
594 number of UDP packets sent. Breakup into separate packages if necessary to
\r
595 avoid fragmentation. (Robert Nagy sponsored by Boffins Technologies)
\r
596 o Removed usage of Microsoft Agents library (Server ran out of memory after a
\r
597 while) in favour of direct synchronous invocations.
\r
601 CasparCG Server 2.0.4 Beta 1 (as compared to 2.0.3 Stable)
\r
602 ==========================================================
\r
606 o Front-end GUI for simplified configuration and easy access to common tasks.
\r
607 (Thomas Kaltz III and Jeff Lafforgue)
\r
608 o Added support for video and images file thumbnail generation. By default the
\r
609 media directory is scanned every 5 seconds for new/modified/removed files
\r
610 and thumbnails are generated/regenerated/removed accordingly.
\r
611 o Support for new video modes: 1556p2398, 1556p2400, 1556p2500, 2160p2398,
\r
612 2160p2400, 2160p2500, 2160p2997 and 2160p3000.
\r
613 o Experimental ATI graphics card support by using static linking against SFML
\r
614 instead of dynamic. Should improve ATI GPU support, but needs testing.
\r
615 o Added support for playback and pass-through of up to 16 audio channels. See
\r
616 http://casparcg.com/forum/viewtopic.php?f=3&t=1453 for more information.
\r
617 o Optimizations in AMCP protocol implementations for large incoming messages,
\r
618 for example base64 encoded PNG images.
\r
619 o Logging output now includes milliseconds and has modified format:
\r
620 YYYY-MM-DD hh:mm:ss.zzz
\r
621 o Improved audio playback with 720p5994 and 720p6000 channels.
\r
622 o An attempt to improve output synchronization of consumers has been made. Use
\r
629 <embedded-audio>true</embedded-audio>
\r
633 <key-only>true</key-only>
\r
638 ...to instruct the server to keep both DeckLink consumers in sync with each
\r
639 other. Consider this experimental, so don't wrap everything in
\r
640 <synchronizing /> unless synchronization of consumer outputs is needed. For
\r
641 synchronization to be effective all synchronized cards must have genlock
\r
642 reference signal connected.
\r
643 o Transfer of source code and issue tracker to github. (Thomas Kaltz III)
\r
647 o Fixed a problem where the first frame was not always shown on LOAD.
\r
653 o Support for layer consumers for listening to frames coming out of producers.
\r
658 o Added support for a master volume mixer setting for each channel.
\r
662 o Added support for chroma keying. (Cambell Prince)
\r
663 o Fixed bug where MIXER CONTRAST set to < 1 can cause transparency issues.
\r
664 o Experimental support for straight alpha output.
\r
668 o Avoid that the FFmpeg consumer blocks the channel output when it can't keep
\r
669 up with the frame rate (drops frames instead).
\r
670 o Added support for to create a separate key and fill file when recording with
\r
671 the FFmpeg consumer. Add the SEPARATE_KEY parameter to the FFmpeg consumer
\r
672 parameter list. The key file will get the _A file name suffix to be picked
\r
673 up by the separated_producer when doing playback.
\r
674 o The Image consumer now writes to the media folder instead of the data
\r
676 o Fixed bug in DeckLink consumer where we submit too few audio samples to the
\r
677 driver when the video format has a frame rate > 50.
\r
678 o Added another experimental DeckLink consumer implementation where scheduled
\r
679 playback is not used, but a similar approach as in the bluefish consumer
\r
680 where we wait for a frame to be displayed and then display the next frame.
\r
681 It is configured via a <blocking-decklink> consumer element. The benefits of
\r
682 this consumer is lower latency and more deterministic synchronization
\r
683 between multiple instances (should not need to be wrapped in a
\r
684 <synchronizing> element when separated key/fill is used).
\r
688 o Added support for playing .swf files using the Flash producer. (Robert Nagy)
\r
689 o Image producer premultiplies PNG images with their alpha.
\r
690 o Image producer can load a PNG image encoded as base64 via:
\r
691 PLAY 1-0 [PNG_BASE64] <base64 string>
\r
692 o FFmpeg producer can now use a directshow input filters:
\r
693 PLAY 1-10 "dshow://video=Some Camera"
\r
694 (Cambell Prince, Julian Waller and Robert Nagy)
\r
695 o New layer producer which directs the output of a layer to another layer via
\r
696 a layer consumer. (Cambell Prince)
\r
700 o The master volume feature is controlled via the MASTERVOLUME MIXER
\r
701 parameter. Example: MIXER 1 MASTERVOLUME 0.5
\r
702 o THUMBNAIL LIST/RETRIEVE/GENERATE/GENERATE_ALL command was added to support
\r
703 the thumbnail feature.
\r
704 o ADD 1 FILE output.mov SEPARATE_KEY activates the separate key feature of the
\r
705 FFmpeg consumer creating an additional output_a.mov containing only the key.
\r
706 o Added KILL command for shutting down the server without console access.
\r
707 o Added RESTART command for shutting down the server in the same way as KILL
\r
708 except that the return code from CasparCG Server is 5 instead of 0, which
\r
709 can be used by parent process to take other actions. The
\r
710 'casparcg_auto_restart.bat' script restarts the server if the return code is
\r
712 o DATA RETRIEVE now returns linefeeds encoded as an actual linefeed (the
\r
713 single character 0x0a) instead of the previous two characters:
\r
715 o MIXER CHROMA command added to control the chroma keying. Example:
\r
716 MIXER 1-1 CHROMA GREEN|BLUE 0.10 0.04
\r
718 o Fixed bug where MIXER FILL overrides any previous MIXER CLIP on the same
\r
719 layer. The bug-fix also has the side effect of supporting negative scale on
\r
720 MIXER FILL, causing the image to be flipped.
\r
721 o MIXER <ch> STRAIGHT_ALPHA_OUTPUT added to control whether to output straight
\r
723 o Added INFO <ch> DELAY and INFO <ch>-<layer> DELAY commands for showing some
\r
724 delay measurements.
\r
725 o PLAY 1-1 2-10 creates a layer producer on 1-1 redirecting the output of
\r
726 2-10. (Cambell Prince)
\r
730 o Support for sending OSC messages over UDP to either a predefined set of
\r
731 clients (servers in the OSC sense) or dynamically to the ip addresses of the
\r
732 currently connected AMCP clients.
\r
733 (Robert Nagy sponsored by Boffins Technologies)

\r
754 CasparCG Server 2.0.3 Stable (as compared to 2.0.3 Alpha)
\r
755 =========================================================
\r
760 o Fixed dead-lock that can occur with multiple mixer tweens. (Robert Nagy)
\r
765 o DATA STORE now supports creating folders of path specified if they does not
\r
766 exist. (Jeff Lafforgue)
\r
767 o DATA REMOVE command was added. (Jeff Lafforgue)
\r
771 CasparCG Server 2.0.3 Alpha (as compared to 2.0 Stable)
\r
772 =======================================================
\r
777 o Data files are now stored in UTF-8 with BOM. Latin1 files are still
\r
778 supported for backwards compatibility.
\r
779 o Commands written in UTF-8 to log file but only ASCII characters to console.
\r
780 o Added supported video formats:
\r
781 + 720p2398 (not supported by DeckLink)
\r
782 + 720p2400 (not supported by DeckLink)
\r
785 + 720p30 (not supported by DeckLink)
\r
786 + 720p29.976 (not supported by DeckLink)
\r
791 o CLK protocol implementation can now serve more than one connection at a time
\r
793 o Added timeline support to the CLK protocol.
\r
794 o Refactored parts of the CLK parser implementation.
\r
799 o Consumers on same channel now invoked asynchronously to allow for proper
\r
800 sync of multiple consumers.
\r
801 o System audio consumer:
\r
802 + no longer provides sync to the video channel.
\r
804 + Support for multiple screen consumers on the same channel
\r
805 + No longer spin-waits for vsync.
\r
806 + Now deinterlaces to two separate frames so for example 50i will no longer
\r
807 be converted to 25p but instead to 50p for smooth playback of interlaced
\r
809 o DeckLink consumer now logs whether a reference signal is detected or not.
\r
814 o Image scroll producer:
\r
815 + Field-rate motion instead of frame-rate motion with interlaced video
\r
816 formats. This can be overridden by giving the PROGRESSIVE parameter.
\r
817 + SPEED parameter now defines pixels per frame/field instead of half pixels
\r
818 per frame. The scrolling direction is also reversed so SPEED 0.5 is the
\r
819 previous equivalent of SPEED -1. Movements are done with sub-pixel
\r
821 + Fixed incorrect starting position of image.
\r
822 + Rounding error fixes to allow for more exact scrolling.
\r
823 + Added support for motion blur via a new BLUR parameter
\r

\r
848 ==================================================
\r
854 + Both encoding and decoding.
\r
856 + Updated audio-pipeline for native NTSC support. Previous implementation
\r
857 did not fully support NTSC audio and could cause incorrect behaviour or
\r
863 o File Consumer added
\r
864 + See updated wiki or ask in forum for more information.
\r
865 + Should support anything FFmpeg supports. However, we will work mainly with
\r
866 DNxHD, PRORES and H264.
\r
867 - Key-only is not supported.
\r
868 o Bluefish Consumer
\r
869 + 24 bit audio support.

\r
892 + Fixed bug with fps calculation.
\r
893 + Improved auto-transcode accuracy.
\r
894 + Improved seeking accuracy.
\r
895 + Fixed bug with looping and LENGTH.
\r

\r
910 reduces command execution latencies, especially when sending a lot of
\r
911 commands in a short timespan.
\r
912 o Fixed CINF command.
\r
913 o ADD/REMOVE no longer require subindex,
\r

923 + INFO TEMPLATE mytemplate (template meta-data info, e.g. field names).
\r
924 o CG INFO command has been extended.
\r
925 + CG INFO 1 (template-host information, e.g. what layers are occupied).
\r
930 o Fixed alpha with blend modes.
\r
931 o Automatically deinterlace for MIXER FILL commands.
\r
936 o SET MODE now reverts back to old video-mode on failure.

967 o Support for FFmpeg-filters such as (ee http://ffmpeg.org/libavfilter.html)
\r
968 + yadif deinterlacer (optimized in CasparCG for full multi-core support)
\r
973 o 32-bit SSE optimized audio pipeline.
\r
974 o DeckLink-Consumer uses external-key by default.
\r
975 o DeckLink-Consumer has 24 bit embedded-audio support.

988 + interlacing (50p -> 50i)
\r
989 + deinterlacing (50i -> 25p)
\r
990 + bob-deinterlacing (50i -> 50p)
\r
991 + bob-deinterlacing and reinterlacing (w1xh150i -> w2xh250i)
\r
992 + doubling (25p -> 50p)
\r
993 + halfing (50p -> 25p)
\r
994 + field-order swap (upper <-> lower)
\r
995 o Screen consumer now automatically deinterlaces when receiving interlaced
\r
997 o Optimized renderer.

998 o Renderer can now be run asynchronously with producer by using a
\r
999 producer-buffer size greater than 0.
\r
1000 o Improved error and crash recovery.
\r
1001 o Improved logging.
\r
1002 o Added Image-Scroll-Producer.
\r
1003 o Key-only has now near zero performance overhead.
\r
1004 o Reduced memory requirements.
\r
1005 o Removed "warm up lag" which occurred when playing the first media clip after
\r
1006 the server has started.

\r
1013 EMPTY, BLACK, RED etc...
\r
1014 o Alpha value in color codes is now optional.
\r
1015 o More than 2 DeckLink cards might be possible but have not yet been tested.
\r
1019 CasparCG Server 2.0 Alpha (as compared to 1.8)
\r
1020 ==============================================
\r
1025 o Mayor refactoring for improved readability and maintainability.
