Hi Carl,

In trying to grab a frame every 30 seconds (or every 900 frames -
close enough) I see tc spending time 'skipping frames' - any way to
get it to seek ahead some number of bytes or something? (close, even
for wide values of close, would be fine)
I switched to -c because I needed split-second accuracy, but if you
don't, try --frame_interval. It may even be frame-accurate now.
transcode -q 0 -o $DDIR/$FIL.img -y im -F png -x ffmpeg,null -i
$DDIR/$FIL.dv --frame_interval 900 2> /dev/null
If you try, let us know what performance you get.
Cheers,
Dave
