@chapter General Questions
@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
standard (note that there are many other coding formats that use this
same standard). Thus, use '-vcodec mpeg4' to encode in these formats. The
same standard). Thus, use '-c:v 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.
