[Ffmpeg-devel] bug report: conversion-time issues

[Projectshifter]

The server I'm installing FFmpeg runs CentOS (yuk!), but it was recently
redone.  It had 2 different versions off ffmpeg in the beginning, one that I
personally patched to allow all wmv formats, and then one from you guys
after the main version was patched, and it was running fine.  They redid the
OS and reinstalled the services, and that's when problems started
happening.  A few days ago there was a problem with configure not
succeeding, but I waited 24 hours and got the new version off of subversion
and it worked fine.  Everything compiles just fine if I use the latest
version, or the one I downloaded a couple weeks ago that supported wmv
formats natively.  The one I patched doesn't compile properly, I know it's
an ld problem and I'd rather not mess with it when I'd rather have a version
that has it natively supported.  The conversion process succeeds (through
exec()'ing a bash file that handles it in PHP), but the videos came out
choppy on the current version.  The videos seem to suceed and come out more
or less fine with the version I've got two weeks ago.  I've tried several
command line options, the usual is just "ffmpeg -i input.wmv -f flv -s
320x240 -sameq output.flv", but the bash file that php calls to is just
"ffmpeg -i $1 -ar 22050 -ab 32 -s 320x240 -b 512 -f flv $2"  It happens more
or less on every file that I've tested with.  I tried it with gdb and it
says that the program exits normally, which explains why it produces regular
files, but the output of ffmpeg is as follows:

Obviously it's compiled with just enabling static and the link to lame.  The
current ffmpeg version which I downloaded I believe last night seems to
ignore the quality settings and gives really choppy and poor quality videos,
where as the one from a couple weeks ago that I'm using produces more or
less proper videos, but it still results in a lot of errors.
Thanks,
