\r
CasparCG Server 2.0.7 (as compared to CasparCG Server 2.0.7 Beta 2)\r
===================================================================\r
\r
General\r
-------\r
\r
  o Added support for using a different configuration file at startup than the\r
    default casparcg.config by simply adding the name of the file to use as the\r
    first command line argument to casparcg.exe.\r
  o Fixed various bugs.\r
\r
AMCP\r
----\r
\r
  o Added RESUME command to complement PAUSE. (Peter Keuter)\r
\r
Consumers\r
---------\r
\r
  o Removed blocking_decklink_consumer. It was more like an experiment at best\r
    and its usefulness was questionable.\r
\r
HTML producer\r
-------------\r
\r
  o No longer tries to play all files with a . in their name.\r
    (Georgi Chorbadzhiyski)\r
  o Reimplemented using CEF3 instead of Berkelium, which enables use of WebGL\r
    and more. CEF3 is actively maintained, which Berkelium is not. (Robert Nagy)\r
  o Implements a custom version of window.requestAnimationFrame which will\r
    follow the pace of the channel, for perfectly smooth animations.\r
  o No longer manually interlaces frames, to allow for mixer fill transforms\r
    without artifacts.\r
  o Now uses CEF3 event loop to avoid 100% CPU core usage.\r
\r
\r
\r
CasparCG Server 2.0.7 Beta 2 (as compared to CasparCG Server 2.0.7 Beta 1)\r
==========================================================================\r
\r
General\r
-------\r
\r
  o Added sendings of OSC messages for channel_grid channel in addition to\r
    regular channels.\r
\r
Producers\r
---------\r
\r
  o FFmpeg: Reports correct nb_frames() when using SEEK (Thomas Kaltz III)\r
  o Flash: Fixed bug wherer CG PLAY, CG INVOKE\r
\r
Consumers\r
---------\r
\r
  o channel_consumer: Added support for more than one channel_consumer per\r
    channel.\r
  o decklink_consumer: Added support for a single instance of the consumer to\r
    manage a separate key output for use with decklink duo/quad cards:\r
\r
    <decklink>\r
      <device>1</device>\r
      <key-device>2</key-device>\r
      <keyer>external_separate_device</keyer>\r
    </decklink>\r
\r
    ...in the configuration will enable the feature. The value of <key-device />\r
    defaults to the value of <device /> + 1.\r
  o synchronizing_consumer: Removed in favour of a single decklink_consumer\r
    managing both fill and key device.\r
  o streaming_consumer: A new implementation of ffmpeg_consumer with added\r
    support for streaming and other PTS dependent protocols. Examples:\r
\r
    <stream>\r
      <path>udp://localhost:5004</path>\r
      <args>-vcodec libx264 -tune zerolatency -preset ultrafast -crf 25 -format mpegts -vf scale=240:180</args>\r
    </stream>\r
\r
    ...in configuration or:\r
\r
    ADD 1 STREAM udp://localhost:5004 -vcodec libx264 -tune zerolatency -preset ultrafast -crf 25 -format mpegts -vf scale=240:180\r
\r
    ...via AMCP. (Robert Nagy sponsored by Ericsson Broadcasting Services)\r
  o newtek_ivga_consumer: Added support for iVGA consumer to not provide channel\r
    sync even though connected. Useful for iVGA clients that downloads as fast\r
    as possible instead of in frame-rate pace, like Wirecast. To enable:\r
\r
    <newtek-ivga>\r
      <provide-sync>false</provide-sync>\r
    </newtek-ivga>\r
\r
    ...in config to not provide channel sync when connected. The default is\r
    true.\r
\r
AMCP\r
----\r
\r
  o Added support in ADD and REMOVE for a placeholder <CLIENT_IP_ADDRESS> which\r
    will resolve to the connected AMCP client's IPV4 address.\r
  o Fixed bug where AMCP commands split into multiple TCP packets where not\r
    correctly parsed (http://casparcg.com/forum/viewtopic.php?f=3&t=2480)\r
\r
\r
\r
CasparCG Server 2.0.7 Beta 1 (as compared to 2.0.6 Stable)\r
==========================================================\r
\r
General\r
-------\r
  o FFmpeg: Upgraded to master and adapted CasparCG to FFmpeg API changes\r
    (Robert Nagy sponsored by SVT)\r
  o FFmpeg: Fixed problem with frame count calculation (Thomas Kaltz III)\r
  o Fixed broken CG UPDATE.\r
\r
Producers\r
---------\r
\r
  o New HTML producer has been created (Robert Nagy sponsored by Flemish Radio\r
    and Television Broadcasting Organization, VRT)\r
\r
\r
\r
CasparCG Server 2.0.6 Stable (as compared to 2.0.4 Stable)\r
==========================================================\r
\r
General\r
-------\r
  o iVGA: Allow for the server to work without Processing.AirSend.x86.dll to\r
    prevent a possible GPL violation. It is available as a separate optional\r
    download.\r
  o iVGA: Only provide sync to channel while connected, to prevent channel\r
    ticking too fast.\r
  o FFmpeg: Fixed bug during deinterlace-bob-reinterlace where output fields\r
    were offset by one field in relation to input fields.\r
  o FFmpeg: Fixed bug in ffmpeg_consumer where an access violation occurred\r
    during destruction.\r
  o FFmpeg: Improved seeking. (Robert Nagy and Thomas Kaltz III)\r
  o Frontend: Only writes elements to casparcg.config which overrides a default\r
    value to keep the file as compact as possible.\r
  o System audio: Patched sfml-audio to work better with oal-consumer and\r
    therefore removed portaudio as the system audio implementation and went back\r
    to oal.\r
  o Flash: Changed so that the initial buffer fill of frames is rendered at a\r
    frame-duration pace instead of as fast as possible. Otherwise time based\r
    animations render incorrectly. During buffer recovery, a higher paced\r
    rendering takes place, but still not as fast as possible, which can cause\r
    animations to be somewhat incorrectly rendered. This is the only way though\r
    if we want the buffer to be able to recover after depletion.\r
  o Fixed race condition during server shutdown.\r
  o OSC: outgoing audio levels from the audio mixer for each audio channel is\r
    now transmitted (pFS and dBFS). (Thomas Kaltz III)\r
  o Stage: Fixed bug where tweened transforms were only ticked when a\r
    corresponding layer existed.\r
  o Screen consumer: Added borderless option and correct handling of name\r
    option. (Thomas Kaltz III)\r
  o AMCP: CLS now reports duration and framerate for MOVIE files were\r
    information is possible to extract. (Robert Nagy)\r
  o Version bump to keep up with CasparCG Client version.\r
\r
\r
\r
CasparCG Server 2.0.4 Stable (as compared to 2.0.4 Beta 1)\r
==========================================================\r
\r
General\r
-------\r
  o Can now open media with file names that only consist of digits.\r
    (Cambell Prince)\r
  o Miscellaneous stability and performance improvements.\r
\r
Video mixer\r
-----------\r
  o Conditional compilation of chroma key support and straight alpha output\r
    support in shader (just like with blend-modes) because of performance impact\r
    even when not in use on a layer or on a channel. New <mixer /> element added\r
    to configuration for turning on mixer features that not everybody would want\r
    to pay for (performance-wise.) blend-modes also moved into this element.\r
  o Fixed bug where MIXER LEVELS interpreted arguments in the wrong order, so \r
    that gamma was interpreted as max_input and vice versa.\r
\r
Consumers\r
---------\r
  o Added support for NewTek iVGA, which enables the use of CasparCG Server \r
    fill+key output(s) as input source(s) to a NewTek TriCaster without \r
    requiring video card(s) in the CasparCG Server machine, or taking up inputs\r
    in the TriCaster. <newtek-ivga /> element in config enables iVGA on a\r
    channel. (Robert Nagy sponsored by NewTek)\r
  o Decklink: Created custom decklink allocator to reduce the memory footprint.\r
  o Replaced usage of SFML for <system-audio /> with PortAudio, because of\r
    problems with SFML since change to static linkage. Also PortAudio seems to\r
    give lower latency.\r
\r
Producers\r
---------\r
  o FFmpeg: Added support for arbitrary FFmpeg options/parameters\r
    in ffmpeg_producer. (Cambell Prince)\r
  o Flash: Flash Player 11.8 now tested and fully supported.\r
  o Flash: No longer starts a Flash Player to service CG commands that mean\r
    nothing without an already running Flash Player.\r
  o Flash: globally serialize initialization and destruction of Flash Players,\r
    to avoid race conditions in Flash.\r
  o Flash: changed so that the Flash buffer is filled with Flash Player\r
    generated content at initialization instead of empty frames.\r
\r
OSC\r
---\r
  o Performance improvements. (Robert Nagy sponsored by Boffins Technologies)\r
  o Never sends old values to OSC reveivers. Collects the latest value of each\r
    path logged since last UDP send, and sends the new UDP packet (to each\r
    subscribing OSC receiver) with the values collected. (Robert Nagy sponsored\r
    by Boffins Technologies)\r
  o Batches as many OSC messages as possible in an OSC bundle to reduce the \r
    number of UDP packets sent. Breakup into separate packages if necessary to \r
    avoid fragmentation. (Robert Nagy sponsored by Boffins Technologies)\r
  o Removed usage of Microsoft Agents library (Server ran out of memory after a\r
    while) in favour of direct synchronous invocations.\r
\r
\r
\r
CasparCG Server 2.0.4 Beta 1 (as compared to 2.0.3 Stable)\r
==========================================================\r
\r
General\r
-------\r
  o Front-end GUI for simplified configuration and easy access to common tasks.\r
    (Thomas Kaltz III and Jeff Lafforgue)\r
  o Added support for video and images file thumbnail generation. By default the\r
    media directory is scanned every 5 seconds for new/modified/removed files\r
    and thumbnails are generated/regenerated/removed accordingly.\r
  o Support for new video modes: 1556p2398, 1556p2400, 1556p2500, 2160p2398,\r
    2160p2400, 2160p2500, 2160p2997 and 2160p3000.\r
  o Experimental ATI graphics card support by using static linking against SFML\r
    instead of dynamic. Should improve ATI GPU support, but needs testing.\r
  o Added support for playback and pass-through of up to 16 audio channels. See\r
    http://casparcg.com/forum/viewtopic.php?f=3&t=1453 for more information.\r
  o Optimizations in AMCP protocol implementations for large incoming messages,\r
    for example base64 encoded PNG images.\r
  o Logging output now includes milliseconds and has modified format:\r
    YYYY-MM-DD hh:mm:ss.zzz\r
  o Improved audio playback with 720p5994 and 720p6000 channels.\r
  o An attempt to improve output synchronization of consumers has been made. Use\r
    for example:\r
\r
    <consumers>\r
      <synchronizing>\r
        <decklink>\r
          <device>1</device>\r
          <embedded-audio>true</embedded-audio>\r
        </decklink>\r
        <decklink>\r
          <device>2</device>\r
          <key-only>true</key-only>\r
        </decklink>\r
      </synchronizing>\r
    </consumers>\r
\r
    ...to instruct the server to keep both DeckLink consumers in sync with each\r
    other. Consider this experimental, so don't wrap everything in\r
    <synchronizing /> unless synchronization of consumer outputs is needed. For\r
    synchronization to be effective all synchronized cards must have genlock\r
    reference signal connected.\r
  o Transfer of source code and issue tracker to github. (Thomas Kaltz III)\r
\r
Layer\r
-----\r
  o Fixed a problem where the first frame was not always shown on LOAD.\r
    (Robert Nagy)\r
\r
Stage\r
-----\r
\r
  o Support for layer consumers for listening to frames coming out of producers.\r
    (Cambell Prince)\r
\r
Audio mixer\r
-----------\r
  o Added support for a master volume mixer setting for each channel.\r
\r
Video mixer\r
-----------\r
  o Added support for chroma keying. (Cambell Prince)\r
  o Fixed bug where MIXER CONTRAST set to < 1 can cause transparency issues.\r
  o Experimental support for straight alpha output.\r
\r
Consumers\r
---------\r
  o Avoid that the FFmpeg consumer blocks the channel output when it can't keep\r
    up with the frame rate (drops frames instead).\r
  o Added support for to create a separate key and fill file when recording with\r
    the FFmpeg consumer. Add the SEPARATE_KEY parameter to the FFmpeg consumer\r
    parameter list. The key file will get the _A file name suffix to be picked\r
    up by the separated_producer when doing playback.\r
  o The Image consumer now writes to the media folder instead of the data\r
    folder.\r
  o Fixed bug in DeckLink consumer where we submit too few audio samples to the\r
    driver when the video format has a frame rate > 50.\r
  o Added another experimental DeckLink consumer implementation where scheduled\r
    playback is not used, but a similar approach as in the bluefish consumer\r
    where we wait for a frame to be displayed and then display the next frame.\r
    It is configured via a <blocking-decklink> consumer element. The benefits of\r
    this consumer is lower latency and more deterministic synchronization\r
    between multiple instances (should not need to be wrapped in a\r
    <synchronizing> element when separated key/fill is used).\r
\r
Producers\r
---------\r
  o Added support for playing .swf files using the Flash producer. (Robert Nagy)\r
  o Image producer premultiplies PNG images with their alpha.\r
  o Image producer can load a PNG image encoded as base64 via:\r
    PLAY 1-0 [PNG_BASE64] <base64 string>\r
  o FFmpeg producer can now use a directshow input filters:\r
    PLAY 1-10 "dshow://video=Some Camera"\r
    (Cambell Prince, Julian Waller and Robert Nagy)\r
  o New layer producer which directs the output of a layer to another layer via\r
    a layer consumer. (Cambell Prince)\r
\r
AMCP\r
----\r
  o The master volume feature is controlled via the MASTERVOLUME MIXER\r
    parameter. Example: MIXER 1 MASTERVOLUME 0.5\r
  o THUMBNAIL LIST/RETRIEVE/GENERATE/GENERATE_ALL command was added to support\r
    the thumbnail feature.\r
  o ADD 1 FILE output.mov SEPARATE_KEY activates the separate key feature of the\r
    FFmpeg consumer creating an additional output_a.mov containing only the key.\r
  o Added KILL command for shutting down the server without console access.\r
  o Added RESTART command for shutting down the server in the same way as KILL\r
    except that the return code from CasparCG Server is 5 instead of 0, which\r
    can be used by parent process to take other actions. The\r
    'casparcg_auto_restart.bat' script restarts the server if the return code is\r
    5.\r
  o DATA RETRIEVE now returns linefeeds encoded as an actual linefeed (the\r
    single character 0x0a) instead of the previous two characters:\r
    \ followed by n.\r
  o MIXER CHROMA command added to control the chroma keying. Example:\r
    MIXER 1-1 CHROMA GREEN|BLUE 0.10 0.04\r
    (Cambell Prince)\r
  o Fixed bug where MIXER FILL overrides any previous MIXER CLIP on the same\r
    layer. The bugfix also has the side effect of supporting negative scale on\r
    MIXER FILL, causing the image to be flipped.\r
  o MIXER <ch> STRAIGHT_ALPHA_OUTPUT added to control whether to output straight\r
    alpha or not.\r
  o Added INFO <ch> DELAY and INFO <ch>-<layer> DELAY commands for showing some\r
    delay measurements.\r
  o PLAY 1-1 2-10 creates a layer producer on 1-1 redirecting the output of\r
    2-10. (Cambell Prince)\r
\r
OSC\r
---\r
  o Support for sending OSC messages over UDP to either a predefined set of\r
    clients (servers in the OSC sense) or dynamically to the ip addresses of the\r
    currently connected AMCP clients.\r
    (Robert Nagy sponsored by Boffins Technologies)\r
  o /channel/[1-9]/stage/layer/[0-9]\r
    + always             /paused           [paused or not]\r
    + color producer     /color            [color string]\r
    + ffmpeg producer    /profiler/time    [render time]     [frame duration]\r
    + ffmpeg producer    /file/time        [elapsed seconds] [total seconds]\r
    + ffmpeg producer    /file/frame       [frame]           [total frames]\r
    + ffmpeg producer    /file/fps         [fps]\r
    + ffmpeg producer    /file/path        [file path]\r
    + ffmpeg producer    /loop             [looping or not]\r
    + during transitions /transition/frame [current frame]   [total frames]\r
    + during transitions /transition/type  [transition type]\r
    + flash producer     /host/path        [filename]\r
    + flash producer     /host/width       [width]\r
    + flash producer     /host/height      [height]\r
    + flash producer     /host/fps         [fps]\r
    + flash producer     /buffer           [buffered]        [buffer size]\r
    + image producer     /file/path        [file path]\r
\r
\r
\r
CasparCG Server 2.0.3 Stable (as compared to 2.0.3 Alpha)\r
=========================================================\r
\r
Stage\r
-----\r
\r
  o Fixed dead-lock that can occur with multiple mixer tweens. (Robert Nagy)\r
\r
AMCP\r
----\r
\r
  o DATA STORE now supports creating folders of path specified if they does not\r
    exist. (Jeff Lafforgue)\r
  o DATA REMOVE command was added. (Jeff Lafforgue)\r
\r
\r
\r
CasparCG Server 2.0.3 Alpha (as compared to 2.0 Stable)\r
=======================================================\r
\r
General\r
-------\r
\r
  o Data files are now stored in UTF-8 with BOM. Latin1 files are still\r
    supported for backwards compatibility.\r
  o Commands written in UTF-8 to log file but only ASCII characters to console.\r
  o Added supported video formats:\r
    + 720p2398 (not supported by DeckLink)\r
    + 720p2400 (not supported by DeckLink)\r
    + 1080p5994\r
    + 1080p6000\r
    + 720p30 (not supported by DeckLink)\r
    + 720p29.976 (not supported by DeckLink)\r
\r
CLK\r
---\r
\r
  o CLK protocol implementation can now serve more than one connection at a time\r
    safely.\r
  o Added timeline support to the CLK protocol.\r
  o Refactored parts of the CLK parser implementation.\r
\r
Consumers\r
---------\r
\r
  o Consumers on same channel now invoked asynchronously to allow for proper\r
    sync of multiple consumers.\r
  o System audio consumer:\r
    + no longer provides sync to caspar.\r
  o Screen consumer:\r
    + Support for multiple screen consumers on the same channel\r
    + No longer spin-waits for vsync\r
    + Now deinterlaces to two separate frames so for example 50i will no longer\r
      be converted to 25p but instead to 50p for smooth playback of interlaced\r
      content.\r
  o Decklink consumer now logs whether a reference signal is detected or not.\r
\r
Producers\r
---------\r
\r
  o Image scroll producer:\r
    + Field-rate motion instead of frame-rate motion with interlaced video\r
      formats. This can be overridden by giving the PROGRESSIVE parameter.\r
    + SPEED parameter now defines pixels per frame/field instead of half pixels\r
      per frame. The scrolling direction is also reversed so SPEED 0.5 is the\r
      previous equivalent of SPEED -1. Movements are done with subpixel accuracy\r
    + Fixed incorrect starting position of image.\r
    + Rounding error fixes to allow for more exact scrolling.\r
    + Added support for motion blur via a new BLUR parameter\r
    + Added PREMULTIPLY parameter to support images stored with straight alpha.\r
\r
\r
\r

\r
Formats\r
-------\r
\r
  o ProRes Support\r
    + Both encoding and decoding.\r
  o NTSC Support\r
    + Updated audio-pipeline for native NTSC support. Previous implementation\r
      did not fully support NTSC audio and could cause incorrect behaviour or\r
      even crashes.\r
\r
Consumers\r
---------\r
\r
  o File Consumer added\r
    + See updated wiki or ask in forum for more information.\r
    + Should support anything FFmpeg supports. However, we will work mainly with\r
      DNXHD, PRORES and H264.\r
    - Key-only is not supported.\r
  o Bluefish Consumer\r
    + 24 bit audio support.\r
    - Embedded-audio does not work with Epoch cards.\r
  o Decklink Consumer\r
    + Low latency enabled by default.\r
    + Added graphs for driver buffers.\r
  o Screen Consumer\r
    + Changed screen consumer square PAL to the more common wide-square PAL.\r
    + Can now be closed.\r
    + Fixed interpolation artifacts when running non-square video-modes.\r
    + Automatically deinterlace interlaced input.\r
\r
Producers\r
---------\r
\r
  o Decklink Producer\r

    + Fixed bug with duration calculation.\r
    + Fixed bug with fps calculation.\r
    + Improved auto-transcode accuracy.\r
    + Improved seeking accuracy.\r
    + Fixed bug with looping and LENGTH.\r
    + Updated to newer FFmpeg version.\r
    + Fixed incorrect scaling of NTSC DV files.\r
    + Optimized color conversion when using YADIF filters.\r
  o Flash Producer\r
    + Release Flash Player when empty.\r
    + Use native resolution TemplateHost.\r
    + TemplateHosts are now choosen automatically if not configured. The\r
      TemplateHost with the corresponding video-mode name is now chosen.\r
    + Use square pixel dimensions.\r
\r
AMCP\r
----\r
\r
  o When possible, commands will no longer wait for rendering pipeline. This\r
    reduces command execution latencies, especially when sending a lot of\r
    commands in a short timespan.\r
  o Fixed CINF command.\r
  o ADD/REMOVE no longer require subindex,\r
    e.g. "ADD 1 SCREEN" / "REMOVE 1 SCREEN" instead of "ADD 1-1 SCREEN" / ...\r
  o PARAM is renamed to CALL.\r
  o STATUS command is replaced by INFO.\r
  o INFO command has been extended:\r
    + INFO (lists channels).\r
    + INFO 1 (channel info).\r
    + INFO 1-1 (layer info).\r
    + INFO 1-1 F (foreground producer info).\r
    + INFO 1-1 B (background producer info).\r
    + INFO TEMPLATE mytemplate (template meta-data info, e.g. field names).\r
  o CG INFO command has been extended.\r
    + CG INFO 1 (template-host information, e.g. what layers are occupied).\r
\r
Mixer\r
-----\r
\r
  o Fixed alpha with blend modes.\r
  o Automatically deinterlace for MIXER FILL commands.\r
\r
Channel\r
-------\r
\r
  o SET MODE now reverts back to old video-mode on failure.\r
\r
Diagnostics\r
-----------\r
\r
  o Improved graphs and added more status information.\r
  o Print configuration into log at startup.\r
  o Use the same log file for the entire day, instead of one per startup as\r
    previously.\r
  o Diagnostics window is now closable.\r
\r
\r
\r
CasparCG Server 2.0 Beta 1 (as compared to Alpha)\r
=================================================\r
\r
  o Blending Modes (needs to be explicitly enabled)\r
    + overlay\r
    + screen\r
    + multiply\r
    + and many more.\r
  o Added additive keyer in addition to linear keyer.\r
  o Image adjustements\r
    + saturation\r
    + brightness\r
    + contrast\r
    + min input-level\r
    + max input-level\r
    + min output-level\r
    + max output-level\r
    + gamma\r
  o Support for FFmpeg-filters such as (ee http://ffmpeg.org/libavfilter.html)\r
    + yadif deinterlacer (optimized in CasparCG for full multi-core support)\r
    + de-noising\r
    + dithering\r
