With git head from a few hours ago, I can get this to work for mpeg2
output, but not for x264.

So this works as expected:

ffmpeg -i /tank/video/scratch/ashes09-5.vob -r 25 \
    -c:a libfaac -ab:a 128k -ac:a 2 \
    -c:v mpeg2video -s:v 640x360 -aspect:v 16:9 -map 0 \
    -f segment -segment_time 10 -segment_list test.m3u8 \
    -segment_format mpegts stream%05d.ts

This does not:

ffmpeg -i /tank/video/scratch/ashes09-5.vob -r 25 \
    -c:a libfaac -ab:a 128k -ac:a 2 \
    -c:v libx264 -s:v 640x360 -aspect:v 16:9 -map 0 \
    -f segment -segment_time 10 -segment_list test.m3u8 \
    -segment_format mpegts stream%05d.ts

use -vbsf h264_mp4toannexb
av_interleaved_write_frame(): Operation not permitted

If I add the suggested bitstream filter, then this additional error is
output before the 'bitstream malformed' line:

h264_mp4toannexb failed for stream 0, codec libx264: Invalid argument

Source is a PAL MPEG2 ripped from DVD (if that matters).
