@section When will the next FFmpeg version be released? / Why are FFmpeg releases so few and far between?
|
||||
|
||||
Like most open source projects FFmpeg suffers from a certain lack of
|
||||
manpower. For this reason the developers have to prioritize the work
|
||||
they do and putting out releases is not at the top of the list, fixing
|
||||
bugs and reviewing patches takes precedence. Please don't complain or
|
||||
request more timely and/or frequent releases unless you are willing to
|
||||
help out creating them.
|
||||
|
||||
@section I have a problem with an old version of FFmpeg; where should I report it?
|
||||
Nowhere. We do not support old FFmpeg versions in any way, we simply lack
|
||||
the time, motivation and manpower to do so. If you have a problem with an
|
||||
old version of FFmpeg, upgrade to the latest git snapshot. If you
|
||||
still experience the problem, then you can report it according to the
|
||||
guidelines in @url{http://ffmpeg.org/bugreports.html}.

@section How do I encode Xvid or DivX video with ffmpeg?

|

Both Xvid and DivX (version 4+) are implementations of the ISO MPEG-4

same standard). Thus, use '-vcodec mpeg4' to encode in these formats. The

default fourcc stored in an MPEG-4-coded file will be 'FMP4'. If you want

a different fourcc, use the '-vtag' option. E.g., '-vtag xvid' will

force the fourcc 'xvid' to be stored as the video fourcc rather than the

default.
