Patch Rules
should we link or quote some ffmpeg patch rules? e.g. tabs are forbidden, use diff -u or svn diff or (insert git command). it seems like this is a common mistake for SoC students. -- Compn 10:53, 29 March 2008 (EDT)
- Well the mailing list page has a link to the MPlayer patch guidelines, but it's missing a few things such as:
- No trailing whitespace
- Must not break the regression tests
- If it does change the regression tests, you must update regression.ref
- Must check bounds on all input and must not allow overflow or other out-of-bounds condition
- Use meaningful variable names
- Globals/externs should have ff_ prefix to avoid naming conflicts
- Doxygen comments
- No breaking C standards (eg using underscore prefixes)
- Keep { } tidy
- No code duplication
- Workarounds for compiler bugs (eg MSVC) must not break other platforms
- Anything else? -- Mkhodor 13:18, 31 March 2008 (EDT)
- er, the whole rule list is availible here http://ffmpeg.mplayerhq.hu/general.html#SEC20 , feel free to add it-- Compn 14:09, 31 March 2008 (EDT)
Delphine CIN?
But we already have it in FFmpeg - look at libavcodec/dsicinav.c and libavformat/dsicin.c --Kostya 01:43, 31 March 2008 (EDT)
- Awesome. See, that's what this collaborative Wiki model is good for-- keeping me honest. :-) I'll get a test in FATE soon. --Multimedia Mike 02:05, 31 March 2008 (EDT)
new ffmpeg demuxers
from mplayer wishlist:
Port libmpdemux demuxers to libavformat or write your own from scratch. libmpdemux is considered deprecated and should eventually be removed. As of 2008-01-28, the following demuxers are missing from libavformat:
- TiVo (ty streams, not TiVo To Go)
- VIVO
- VQF
- XMMS
- libnemesi
- SL support for MPEG-TS
