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 , 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:
  1. TiVo (ty streams, not TiVo To Go)
  2. VIVO
  3. VQF
  4. XMMS
  5. libnemesi
  6. SL support for MPEG-TS
Vivo is already on the list. Feel free to add more if you can clearly outline the end goal and the steps toward achieving that goal. --Multimedia Mike 14:50, 4 April 2008 (EDT)
