Been playing around further, and this is the best that I have been able to achieve transcode -i /dev/video0 -H 0 -p /dev/dsp -x v4l2,v4l2 -f 24,2 --import_asr 2 --export_fps 24,2 --encode_fields p -g 720x480 -V -y mpeg2enc,mp2enc -F 8 -c 00:00:10 -u 128,3 --nice -17 -o /mnt/md0/video/test The audio is nice and constant and the video looks pretty good. The only hiccup remaining is the fastforward effect. CPU's were also used quite nicely. Here is the transcode output. [export_mpeg2enc.so] *** init-v *** ! [export_mp2enc.so] *** init-v *** ! [export_mpeg2enc.so] cmd=mpeg2enc -v 0 -I 0 -f 8 -b 1800 -F 2 -n n -a 2 -o "/mnt/md0/video/test.m2v" [export_mp2enc.so] (60/4096) cmd=mp2enc -v 0 -r 48000 -b 128 -s -o "/mnt/md0/video/test.mpa" encoding frame [239], 9.04 fps, 100.0%, ETA: 0:00:00, ( 0| 0|28) [import_v4l2.so]: Totals: sequence V/A: 285/368, frames C/D: 0/0 clean up | frame threads | unload modules | cancel signal | internal threads | done [transcode] encoded 240 frames (0 dropped, 0 cloned), clip length 10.00 s It looks like transcode is only encoding 9'ish FPS On Fri, 2004-08-06 at 13:57, Erik Slagter wrote: > On Fri, 2004-08-06 at 19:04, Michel Bardiaux wrote: > > Gary Major wrote: > > Audio: I know that some DSPs do not support all configs... but do not > > report an error!
