New submission from Herman Kuiper <[email protected]>:
When trying to convert some (generated/captured by a system of a client of ours)
WAV files into MP3 files, ffmpeg hangs at (near) the end of the input file. For
these offending files, when using the -t flag to transcode 1 second less than
the actual duration, ffmpeg usually ends ok.
FFMPEG needs to be killed using one or ^C's. As this process is actually running
on a webserver to convert those WAV for replay in Flash, these hanging FFMPEGs
will clog the server until a couple of them are using 100% CPU.
Shortest command line to reproduce: ffmpeg -v 9 -loglevel 99 -i IRS8C00.wav
1.mp3
Sample offending file uploaded to upload.ffmpeg.org in the folder
/MPlayer/incoming/hermanfrontiernl_ffmpeg_hang_on_convert/hermanfrontiernl_ffmpeg_hang_on_convert.wav
Relevant output logs from FFMPEG attached. Please note that the last line just
keeps repeating until FFMPEG is killed.
FWIW, Windows Media Player correctly plays these files. More offending files can
be supplied on request.
