+\r
+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
- Should inprove ATI card support. Needs testing.\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
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 Fixed bug where MIXER FILL overrides any previous MIXER CLIP on the same\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
