theora - May 2007 - video quality problem, encodeing with ffmpeg2theora -p pro

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 ?

Hi,

any chance you could post say the first few MB of such a file
somewhere? I've got a hunch it has something to do with the way the
audio and video tracks are interleaved and timestamped (forcing the
players to buffer much more than necessary), but I'm not sure ...

cheers,

Conrad.
