CasparCG 2.1.0 (w.r.t 2.0 Stable)
=================================
General
-------
o 64 bit!
o Major code refactoring:
+ Mixer abstraction so different implementations can be created. Currently
CPU mixer and GPU mixer (previously the usage of the GPU was ) exists.
+ Flattened folder structure for easier inclusion of header files.
+ Old Windows specific AsyncEventServer class has been replaced by platform
independent implementation based on Boost.Asio.
+ Pimpl classes are now stack allocated with internal shared_ptr to
implementation, instead of both handle and body being dynamically
allocated. This means that objects are now often passed by value instead
of via safe_ptr/shared_ptr, because they are internally reference counted.
+ Protocol strategies are now easier to implement correctly, because of
separation of state between different client connections.
+ Much more...
o Data files are now stored in UTF-8 with BOM. Latin1 files are still
supported for backwards compatibility
o Commands written in UTF-8 to log file but only ascii characters to console.
o Added supported video formats:
+ 720p2398 (not supported by decklink)
+ 720p2400 (not supported by decklink)
+ 1080p5994
+ 1080p6000
+ 720p30 (not supported by decklink)
+ 720p29.976 (not supported by decklink)
OSC
---
o Technical information about the current state of the server is published via
the OSC protocol via different subjects.
o Examples of information published:
+ Different performance metrics.
+ Producer names
+ Producer specific information
+ Consumer names.
+ Consumer specific information.
CLK
---
o CLK protocol implementation can now serve more than one connection at a time
safely.
o Added timeline support to the CLK protocol.
o Refactored parts of the CLK parser implementation.
Consumers
---------
o Consumers on same channel now invoked asynchronously to allow for proper
sync of multiple consumers.
o System audio consumer:
+ No longer provides sync to caspar.
+ Pushes data to openal instead of being callbacked by SFML when data is
needed.
o Screen consumer:
+ Support for multiple screen consumers on the same channel
+ No longer spin-waits for vsync
+ Now deinterlaces to two separate frames so for example 50i will no longer
be converted to 25p but instead to 50p for smooth playback of interlaced
content.
Producers
---------
o Image scroll producer:
+ Field-rate motion instead of frame-rate motion with interlaced video
formats. This can be overridden by giving the PROGRESSIVE parameter.
+ SPEED parameter now defines pixels per frame/field instead of half pixels
per frame. The scrolling direction is also reversed so SPEED 0.5 is the
previous equivalent of SPEED -1. Movements are done with subpixel accuracy
+ Fixed incorrect starting position of image.
+ Rounding error fixes to allow for more exact scrolling.
+ Added support for motion blur via a new BLUR parameter
+ Added PREMULTIPLY parameter to support images stored with straight alpha.
AMCP
----
o DATA STORE now supports creating folders of path specified if they does not
exist.
o DATA REMOVE command was added.

==================================

did not fully support NTSC audio and could cause incorrect behaviour or
even crashes.
Consumers
---------
o File Consumer added
+ See updated wiki or ask in forum for more information.
+ Should support anything ffmpeg supports. However, we will work mainly with
DNXHD, PRORES and H264.

interleaving.

+ Template-hosts are now choosen automatically if not configured. The
template-host with the corresponding video-mode name is now chosen.
+ Use square pixel dimensions.
AMCP
----
o When possible, commands will no longer wait for rendering pipeline. This
reduces command execution latencies, especially when sending a lot of
commands in a short timespan.
o Fixed CINF command.
o ADD/REMOVE no longer require subindex,
e.g. "ADD 1 SCREEN" / "REMOVE 1 SCREEN" instead of "ADD 1-1 SCREEN" / ...
o PARAM is renamed to CALL.
o STATUS command is replaced by INFO.
o INFO command has been extended:
+ INFO (lists channels).
+ INFO 1 (channel info).
+ INFO 1-1 (layer info).
+ INFO 1-1 F (foreground producer info).
+ INFO 1-1 B (background producer info).
+ INFO TEMPLATE mytemplate (template meta-data info, e.g. field names).
o CG INFO command has been extended.
+ CG INFO 1 (template-host information, e.g. what layers are occupied).
Mixer
-----
o Fixed alpha with blend modes.
o Automatically deinterlace for MIXER FILL commands.
Channel
-------
o SET MODE now reverts back to old video-mode on failure.
Diagnostics
-----------
o Improved graphs and added more status information.
