I'd like to reopen this ticket because ever since upgrading from r16024 to
r16997 (on a SUSE 10.3 32bit), I started getting libmp3lame: output buffer too
small on a ton of videos.
Example:
ffmpeg -v 1 -i 'tmp.10047/42122470_0.flv' -vcodec flv -s 320x240 -r 15 -y -b
218000 -acodec libmp3lame -ab 64kb -ar 44100 -ac 2 -t 30
'tmp.10047/42122470_0.ffmpeg_flv.vb218000.mp3-64.time0-30.320x240.rate15.BLX.flv'

[libmp3lame @ 0x806e350]lame: output buffer too small (buffer index: 9404, free
bytes: 388)
Audio encoding failed
A few weeks ago I've installed ffmpeg on a new 64bit RHEL box and started
receiving the same errors but I wrote it off to the fact that it's 64bit. Now,
however I'm sure it's something with a recent change.
Any ideas?
I've uploaded the sample to the FTP under
Issue719-libmp3lame-output-buffer-too-small/Issue719-libmp3lame-output-buffer-too-small.flv
Note that this is only 1 sample file, I have a lot more that exhibit the same
behavior.
Thanks!
