3 CasparCG 2.0.4 Stable (as compared to 2.0.4 Beta 1)
\r
4 ===================================================
\r
8 o Can now open media with file names that only consist of digits.
\r
9 o Miscellaneous stability and performance improvements.
\r
13 o Conditional compilation of chroma key support and straight alpha output
\r
14 support in shader (just like with blend-modes) because of performance impact
\r
15 even when not in use on a layer/on a channel. New <mixer /> element added to
\r
16 configuration for turning on mixer features that not everybody would want to
\r
17 pay for (performance-wise). blend-modes also moved into this element.
\r
18 o MIXER LEVELS interpreted arguments in the wrong order, so that gamma was
\r
19 interpreted as max_input and vice versa.
\r
23 o Replaced usage of SFML for <system-audio /> with PortAudio, because of
\r
24 problems with SFML since change to static linkage. Also PortAudio seems to
\r
26 o Added support for NewTek iVGA. Enables the use of the CasparCG Server
\r
27 output as an input source in a NewTek TriCaster without requiring a video
\r
28 card. <newtek-ivga /> element in config enables iVGA on a channel.
\r
29 o Decklink: Created custom decklink allocator for reducing memory footprint.
\r
33 o FFmpeg: Added support for arbitrary FFmpeg options in ffmpeg_producer.
\r
34 o Flash: No longer starts a Flash Player to service CG commands that means
\r
35 nothing without an already running Flash Player.
\r
36 o Flash: globally serialize initialization and destruction of Flash Players,
\r
37 to avoid race conditions in Flash.
\r
38 o flash: changed so that the Flash buffer is filled with Flash Player
\r
39 generated content at initialization instead of empty frames.
\r
43 o Performance improvements.
\r
44 o Never send old values to OSC reveivers, collect the latest value of each
\r
45 path logged since last UDP send, and send the new UDP packet (to each
\r
46 subscribing OSC receiver) with the values collected.
\r
47 o Batch as many OSC messages as possible in an OSC bundle to reduce the number
\r
48 of UDP packets sent. Breakup into separate packages if necessary to avoid
\r
50 o Removed usage of Microsoft Agents library (server ran out of memory after a
\r
51 while) in favour of direct synchronous invocations.
\r
57 CasparCG 2.0.4 Beta 1 (as compared to 2.0.3 Stable)
\r
58 ===================================================
\r
62 o Front-end GUI for simplified configuration and easy access to common tasks.
\r
63 o Added support for video and images file thumbnail generation. By default the
\r
64 media directory is scanned every 5 seconds for new/modified/removed files
\r
65 and thumbnails are generated/regenerated/removed accordingly.
\r
66 o Support for new video modes: 1556p2398, 1556p2400, 1556p2500, 2160p2398,
\r
67 2160p2400, 2160p2500, 2160p2997 and 2160p3000.
\r
68 o Experimental ATI graphics card support by using static linking against SFML
\r
69 instead of dynamic. Should improve ATI GPU support, but needs testing.
\r
70 o Added support for playback and pass-through of up to 16 audio channels. See
\r
71 http://casparcg.com/forum/viewtopic.php?f=3&t=1453 for more information.
\r
72 o Optimizations in AMCP protocol implementations for large incoming messages,
\r
73 for example base64 encoded PNG images.
\r
74 o Logging output now includes milliseconds and has modified format:
\r
75 YYYY-MM-DD hh:mm:ss.zzz
\r
76 o Improved audio playback with 720p5994 and 720p6000 channels.
\r
77 o An attempt to improve output synchronization of consumers has been made. Use
\r
84 <embedded-audio>true</embedded-audio>
\r
88 <key-only>true</key-only>
\r
93 ...to instruct the server to keep both DeckLink consumers in sync with each
\r
94 other. Consider this experimental, so don't wrap everything in
\r
95 <synchronizing /> unless synchronization of consumer outputs is needed. For
\r
96 synchronization to be effective all synchronized cards must have genlock
\r
97 reference signal connected.
\r
101 o Fixed a problem where the first frame was not always shown on LOAD.
\r
105 o Added support for a master volume mixer setting for each channel.
\r
109 o Added support for chroma keying.
\r
110 o Fixed bug where MIXER CONTRAST set to < 1 can cause transparency issues.
\r
111 o Experimental support for straight alpha output.
\r
115 o Avoid that the FFmpeg consumer blocks the channel output when it can't keep
\r
116 up with the frame rate (drops frames instead).
\r
117 o Added support for to create a separate key and fill file when recording with
\r
118 the FFmpeg consumer. Add the SEPARATE_KEY parameter to the FFmpeg consumer
\r
119 parameter list. The key file will get the _A file name suffix to be picked
\r
120 up by the separated_producer when doing playback.
\r
121 o The Image consumer now writes to the media folder instead of the data
\r
123 o Fixed bug in DeckLink consumer where we submit too few audio samples to the
\r
124 driver when the video format has a frame rate > 50.
\r
125 o Added another experimental DeckLink consumer implementation where scheduled
\r
126 playback is not used, but a similar approach as in the bluefish consumer
\r
127 where we wait for a frame to be displayed and then display the next frame.
\r
128 It is configured via a <blocking-decklink> consumer element. The benefits of
\r
129 this consumer is lower latency and more deterministic synchronization
\r
130 between multiple instances (should not need to be wrapped in a
\r
131 <synchronizing> element when separated key/fill is used).
\r
135 o Added support for playing .swf files using the Flash producer.
\r
136 o Image producer premultiplies PNG images with their alpha.
\r
137 o Image producer can load a PNG image encoded as base64 via:
\r
138 PLAY 1-0 [PNG_BASE64] <base64 string>
\r
139 o FFmpeg producer can now use a directshow input filters:
\r
140 PLAY 1-10 "dshow://video=Some Camera"
\r
144 o The master volume feature is controlled via the MASTERVOLUME MIXER
\r
145 parameter. Example: MIXER 1 MASTERVOLUME 0.5
\r
146 o THUMBNAIL LIST/RETRIEVE/GENERATE/GENERATE_ALL command was added to support
\r
147 the thumbnail feature.
\r
148 o ADD 1 FILE output.mov SEPARATE_KEY activates the separate key feature of the
\r
149 FFmpeg consumer creating an additional output_a.mov containing only the key.
\r
150 o Added KILL command for shutting down the server without console access.
\r
151 o Added RESTART command for shutting down the server in the same way as KILL
\r
152 except that the return code from CasparCG Server is 5 instead of 0, which
\r
153 can be used by parent process to take other actions. The
\r
154 'casparcg_auto_restart.bat' script restarts the server if the return code is
\r
156 o DATA RETRIEVE now returns linefeeds encoded as an actual linefeed (the
\r
157 single character 0x0a) instead of the previous two characters:
\r
159 o MIXER CHROMA command added to control the chroma keying. Example:
\r
160 MIXER 1-1 CHROMA GREEN|BLUE 0.10 0.04
\r
161 o Fixed bug where MIXER FILL overrides any previous MIXER CLIP on the same
\r
162 layer. The bugfix also has the side effect of supporting negative scale on
\r
163 MIXER FILL, causing the image to be flipped.
\r
164 o MIXER <ch> STRAIGHT_ALPHA_OUTPUT added to control whether to output straight
\r
166 o Added INFO <ch> DELAY and INFO <ch>-<layer> DELAY commands for showing some
\r
167 delay measurements.
\r
172 o Support for sending OSC messages over UDP to either a predefined set of
\r
173 clients (servers in the OSC sense) or dynamically to the ip addresses of the
\r
174 currently connected AMCP clients.
\r
175 o /channel/[1-9]/stage/layer/[0-9]
\r
176 + always /paused [paused or not]
\r
177 + color producer /color [color string]
\r
178 + ffmpeg producer /profiler/time [render time] [frame duration]
\r

\r
190 + flash producer /buffer [buffered] [buffer size]
\r
191 + image producer /file/path [file path]
\r

\r
220 o Added supported video formats:
\r
221 + 720p2398 (not supported by DeckLink)
\r
222 + 720p2400 (not supported by DeckLink)
\r
225 + 720p30 (not supported by DeckLink)
\r
226 + 720p29.976 (not supported by DeckLink)

\r
244 + Support for multiple screen consumers on the same channel
\r
245 + No longer spin-waits for vsync
\r
246 + Now deinterlaces to two separate frames so for example 50i will no longer
\r
247 be converted to 25p but instead to 50p for smooth playback of interlaced
\r
249 o Decklink consumer now logs whether a reference signal is detected or not.
\r
254 o Image scroll producer:
\r
255 + Field-rate motion instead of frame-rate motion with interlaced video
\r
256 formats. This can be overridden by giving the PROGRESSIVE parameter.
\r
257 + SPEED parameter now defines pixels per frame/field instead of half pixels
\r
258 per frame. The scrolling direction is also reversed so SPEED 0.5 is the
\r
259 previous equivalent of SPEED -1. Movements are done with subpixel accuracy
\r
260 + Fixed incorrect starting position of image.
\r
261 + Rounding error fixes to allow for more exact scrolling.
\r
262 + Added support for motion blur via a new BLUR parameter

\r
300 o File Consumer added
\r
301 + See updated wiki or ask in forum for more information.
\r
302 + Should support anything FFmpeg supports. However, we will work mainly with
\r
303 DNXHD, PRORES and H264.
\r
304 - Key-only is not supported.
\r

\r
347 reduces command execution latencies, especially when sending a lot of
\r
348 commands in a short timespan.
\r
349 o Fixed CINF command.
\r
350 o ADD/REMOVE no longer require subindex,

\r
445 o Memory support increased from standard 2 GB to 4 GB on 64 bit Win 7 OS.
\r
446 o Added support for 2* Decklink cards in FullHD.
\r
447 o Misc bugs fixes and performance improvements.
