Hello all and thanks,
I have encoded several .vob with " ffmpeg2theoar -p preveiw " with no
problems at all. The quality is exellent. These .vob were ripped with
vobcopy.
The problem I am having is when I encode a .vob with " ffmpeg2theora -p pro ".
The resulting .ogg will not play correctly with vlc or kaffeine. The vedio
is jerky and the sound go out of sycro just after the start of the video.
The video veiwer takes up all the cpu resourses for the .ogg when encoded
with " ffmpeg2theora -p pro ".
If I play the .ogg file thats been encode with " ffmpeg2theoar -p preveiw "
the cpu useage is only 20% ? All seems OK there.
I have looked on the debian bugs report for this package and I can see no
mention any problem simular to what I am having with encoding with "
ffmpeg2theoar -p pro ".
There was a site I found with test .ogg files for the veiwer. These where
encoded as -p pro and -p preveiw. All the test files ran OK with the video
veiwers and I have veiwed other viedos encoded as " -p pro " with no problems
at all.
Its just the encodeding I do with " ffmpeg2theora -p pro " that goes wrong.
OS : Debian etch
ffmpeg2theora 0.16-2+b1
libtheora0 0.0.0.alpha7.dfsg-1.1
Cpu 2 x : Pentium III (Coppermine) cpu MHz : 665.218
MemTotal: 256928 kB
So any idears what is be going wrong ?
Regards
