+CasparCG 2.0.4 Stable (as compared to 2.0.4 Beta 1)\r
+===================================================\r
\r
General\r
-------\r
\r
- o Logging output now includes milliseconds and has modified format:\r
- yyyy-mm-d HH:MM:SS.ZZZ\r
- o Added support for generating thumbnails for media files. Currently only\r
- video files and images are supported. By default the media directory is\r
- scanned every 5 seconds for new/modified/removed files and thumbnails are\r
- generated/regenerated/removed accordingly.\r
- o Support for new video modes: 2k2398, 2k2400, 2k2500, 4k2398, 4k2400, 4k2500,\r
- 4k2997 and 4k3000.\r
- o Optimizations in AMCP protocol implementations for large incoming messages\r
- like for example base64 encoded PNG-images.\r
- o Added support for more than 2 audio channels in caspar. See\r
+ o Can now open media with digit only names.\r
+ o Misc stability and performance improvements.\r
+\r
+Video mixer\r
+-----------\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/on a channel. New <mixer /> element added to\r
+ configuration for turning on mixer features that not everybody would want to\r
+ pay for (performance-wise). blend-modes also moved into this element.\r
+ o MIXER LEVELS interpretet arguments in the wrong order, so that gamma was\r
+ interpreted as max_input and vice versa.\r
+\r
+Consumers\r
+---------\r
+\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
+ o Added support for NewTek AirPlay. Enables the use of the CasparCG Server\r
+ output as an input source in a NewTek TriCaster without requiring a video\r
+ card. <newtek /> element in config enables AirPlay on a channel.\r
+ o Decklink: Created custom decklink allocator for reducing memory footprint.\r
+\r
+Producers\r
+---------\r
+\r
+ o ffmpeg: Added support for arbitrary ffmpeg options in ffmpeg_producer.\r
+ o flash: No longer starts a flash player to service CG commands that means\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
+\r
+ o Performance improvements.\r
+ o Never send old values to OSC reveivers, collect the latest value of each\r
+ path logged since last UDP send, and send the new UDP packet (to each\r
+ subscribing OSC receiver) with the values collected.\r
+ o Batch as many OSC messages as possible in an OSC bundle to reduce the number\r
+ of UDP packets sent. Breakup into separate packages if necessary to avoid\r
+ fragmentation.\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
+CasparCG 2.0.4 Beta 1 (as compared to 2.0.3 Stable)\r
+===================================================\r
+\r
+General\r
+-------\r
+\r
+ o Front-end GUI for simplified configuration and easy access to common tasks.\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 ATI graphics card support. Static linking against SFML instead of dynamic.\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
\r
Layer\r
-----\r
\r
o Added support for chroma keying.\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
\r
- o Simplified implementation of bluefish consumer, with regards to\r
- o Avoid that the ffmpeg consumer blocks the channel output when it can't keep\r
- up with the frame rate (drops instead).\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 suffix to be picked up by the\r
- separated_producer when doing playback.\r
- o The image consumer now writes to the media folder instead of the data\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 samples to the driver\r
- when the video format has a frame rate > 50.\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
\r
- o Added support for playing .swf files using the flash producer.\r
- o image producer premultiplies PNG images with their alpha.\r
- o image producer can load a PNG image encoded as base64 via:\r

o MIXER CHROMA command added to control the chroma keying. Example:\r
MIXER 1-1 CHROMA GREEN|BLUE 0.10 0.04\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
