Hi,
I filled a bug about transition in OpenGL with MJPEG files.
http://bugs.cinelerra.org/show_bug.cgi?id=449
It is very funny bug because if affects combination of file format and
output type.
It seems to be a major problem (at least for me) when working with HDV.
I find useless using MPEG-2 files directly as the responsivity of playback
is too low and if more than 1 track is active playback goes below 10fps.
I wants to have proxies without time compression - it is really fast, makes
backward playback smooth etc. I tried MJPEG and it is almost perfect,
but transitions are not displayed correctly in OpenGL accelerated
compositor.
Then i stopped to use transitions ;-)
If you have any ideas how i can get around this? Maybe some another
way of encoding should help? I do:
for i in *.m2t;
do
mencoder -mc 0 -noskip $i -ovc lavc -lavcopts vcodec=mjpeg -vf
scale=720:540 -oac pcm -o `basename $i m2t`avi;
done
the best
