Description Daiajo Tibdixious 2007-02-03 07:03:06 UTC
# name=097
# transcode -i ${name}.avi -y ffmpeg --export_prof dvd-pal --export_fps 25 --export_asr 2 -o ${name} -D0 -b224 -N 0x2000 -m ${name}.ac3 -J modfps=clonetype=3
Segmentation fault00000-033996],  14.23 fps, EMT: 0:23:37, ( 0| 0| 0)
The "Segmentation fault" message overwrites the last line of output.
The transcode operation appears to be successful, as after
# mplex -f 8 -o ${name}.mpg ${name}.m2v ${name}.ac3
the mpg file is playable in mplayer, video and audio are as expected, and the sound is in sync with the video, i.e. perfect.

Reproducible: Always

Steps to Reproduce:
1. obtain a BLAH.avi file
2. name=BLAH
3. transcode -i ${name}.avi -y ffmpeg --export_prof dvd-pal --export_fps 25 --export_asr 2 -o ${name} -D0 -b224 -N 0x2000 -m ${name}.ac3 -J modfps=clonetype=3
