FreeBSD 7.0-RC2 @ amd64 Note: Some of these configs are maybe non-sense, but that was just my best try to get the latest svn version to compile on FreeBSD. Later versions in the FreeBSD ports collection suffered from the same problem (SVN-r14424). I use ffmpeg solely for audio re-encoding. For some files, I get many lines of "lame: output buffer too small" and the output file is truncated. This happened only with some files and then I found out that decreasing the target audio quality would solve the problem. File: http://tmp.tomas-muller.net/32.mp3 (~6 MB). ffmpeg -i 32.mp3 -acodec libmp3lame -aq 2 -ar 44100 -ac 2 test-bad.mp3 exhibits the error, while ffmpeg -i 32.mp3 -acodec libmp3lame -aq 3 -ar 44100 -ac 2 test-bad.mp3 (decreased audio quality) does not. When I increased the buffer size at libavcodec/libmp3lame.c (line 31: #define BUFFER_SIZE) and recompiled, problem was solved. My guess is that increasing the BUFFER_SIZE to accommodate the maximum mp3 bitrate (320kbps) would fix this. libavcodec/libmp3lame.c(31): #define BUFFER_SIZE (7200 + MPA_FRAME_SIZE + MPA_FRAME_SIZE/4) Shouldn't this be MPA_MAX_CODED_FRAME_SIZE ? ---------- messages: 3657 priority: normal status: new substatus: new title: libmp3lame: output buffer too small (many times repeated), truncated file type: bug ______________________________________________________ FFmpeg issue tracker <[EMAIL PROTECTED]> <https://roundup.mplayerhq.hu/roundup/ffmpeg/issue719> ______________________________________________________
