1 CasparCG 2.1.0 (w.r.t 2.0 Stable)
\r
2 =================================
\r
8 o Major code refactoring:
\r
9 + Mixer abstraction so different implementations can be created. Currently
\r
10 CPU mixer and GPU mixer (previously the usage of the GPU was ) exists.
\r
11 + Flattened folder structure for easier inclusion of header files.
\r
12 + Old Windows specific AsyncEventServer class has been replaced by platform
\r
13 independent implementation based on Boost.Asio.
\r
14 + Pimpl classes are now stack allocated with internal shared_ptr to
\r
15 implementation, instead of both handle and body being dynamically
\r
16 allocated. This means that objects are now often passed by value instead
\r
17 of via safe_ptr/shared_ptr, because they are internally reference counted.
\r
18 + Protocol strategies are now easier to implement correctly, because of
\r
19 separation of state between different client connections.
\r
21 o Data files are now stored in UTF-8 with BOM. Latin1 files are still
\r
22 supported for backwards compatibility
\r
23 o Commands written in UTF-8 to log file but only ascii characters to console.
\r
24 o Added supported video formats:
\r
25 + 720p2398 (not supported by decklink)
\r
26 + 720p2400 (not supported by decklink)
\r
29 + 720p30 (not supported by decklink)
\r
30 + 720p29.976 (not supported by decklink)
\r
35 o Technical information about the current state of the server is published via
\r
36 the OSC protocol via different subjects.
\r
37 o Examples of information published:
\r
38 + Different performance metrics.
\r
40 + Producer specific information
\r
42 + Consumer specific information.
\r
47 o CLK protocol implementation can now serve more than one connection at a time
\r
49 o Added timeline support to the CLK protocol.
\r
50 o Refactored parts of the CLK parser implementation.
\r
55 o Consumers on same channel now invoked asynchronously to allow for proper
\r
56 sync of multiple consumers.
\r
57 o System audio consumer:
\r
58 + No longer provides sync to caspar.
\r
59 + Pushes data to openal instead of being callbacked by SFML when data is
\r
62 + Support for multiple screen consumers on the same channel
\r
63 + No longer spin-waits for vsync
\r
64 + Now deinterlaces to two separate frames so for example 50i will no longer
\r
65 be converted to 25p but instead to 50p for smooth playback of interlaced
\r
71 o Image scroll producer:
\r
72 + Field-rate motion instead of frame-rate motion with interlaced video
\r
73 formats. This can be overridden by giving the PROGRESSIVE parameter.
\r
74 + SPEED parameter now defines pixels per frame/field instead of half pixels
\r
75 per frame. The scrolling direction is also reversed so SPEED 0.5 is the
\r
76 previous equivalent of SPEED -1. Movements are done with subpixel accuracy
\r
77 + Fixed incorrect starting position of image.
\r
78 + Rounding error fixes to allow for more exact scrolling.
\r
79 + Added support for motion blur via a new BLUR parameter
\r
80 + Added PREMULTIPLY parameter to support images stored with straight alpha.
\r
85 o DATA STORE now supports creating folders of path specified if they does not
\r
87 o DATA REMOVE command was added.
\r
89 CasparCG 2.0 Stable (w.r.t Beta 3)
\r
90 ==================================
\r
95 o Misc stability and performance fixes.
\r
101 + Changed semantics to more closely follow ffmpeg (see forums).
\r
102 + Added options, -r, -acodec, -s, -pix_fmt, -f and more.
\r
104 + Added vsync support.
\r
106 CasparCG 2.0 Beta 3 (w.r.t Beta 1)
\r
107 ==================================
\r
113 + Both encoding and decoding.
\r
115 + Updated audio-pipeline for native NTSC support. Previous implementation
\r
116 did not fully support NTSC audio and could cause incorrect behaviour or
\r
122 o File Consumer added
\r
123 + See updated wiki or ask in forum for more information.
\r
124 + Should support anything ffmpeg supports. However, we will work mainly with
\r
125 DNXHD, PRORES and H264.
\r
126 - Key-only is not supported.
\r
127 o Bluefish Consumer
\r
128 + 24 bit audio support.

132 + Added graphs for driver buffers.
\r
134 + Changed screen consumer square PAL to the more common wide-square PAL.
\r
135 + Can now be closed.

137 + Automatically deinterlace interlaced input.
\r
142 o Decklink Producer
\r
143 + Improved color quality be avoiding uneccessary conversion to BGRA.
\r
145 + Fixed missing alpha for (RGB)A formats when deinterlacing.
\r
146 + Updated buffering to work better with files with long audio/video
\r
148 + Seekable while running and after reaching EOF. CALL 1-1 SEEK 200.

\r
162 template-host with the corresponding video-mode name is now chosen.
\r
163 + Use square pixel dimensions.
\r
168 o When possible, commands will no longer wait for rendering pipeline. This
\r
169 reduces command execution latencies, especially when sending a lot of
\r
170 commands in a short timespan.
\r
171 o Fixed CINF command.
\r
172 o ADD/REMOVE no longer require subindex,
\r
173 e.g. "ADD 1 SCREEN" / "REMOVE 1 SCREEN" instead of "ADD 1-1 SCREEN" / ...
\r
174 o PARAM is renamed to CALL.
\r
175 o STATUS command is replaced by INFO.

\r
178 + INFO 1 (channel info).
\r
179 + INFO 1-1 (layer info).
\r
180 + INFO 1-1 F (foreground producer info).
\r
181 + INFO 1-1 B (background producer info).
\r
182 + INFO TEMPLATE mytemplate (template meta-data info, e.g. field names).
\r
183 o CG INFO command has been extended.
\r
