I saw this extract from a post by Matthias Hopf on the mencoder users list.

-hr-edl-seek is your friend here. -ss never worked reliably, and only
starts at keyframes / I-frames.
Okay for most stuff I-frames is good enough as the occur about every 1/2
second, which is good enough for most people but I still think that
using the edl is better. Then it could be used with the commercial
detect application too and we could remove one of the servers from freevo.
What I do with my buttons is:
EVENTS['video']['LEFT'] = Event(VIDEO_SEND_MPLAYER_CMD, arg='seek -60')
EVENTS['video']['RIGHT'] = Event(VIDEO_SEND_MPLAYER_CMD, arg='seek +60')
EVENTS['video']['UP'] = Event(VIDEO_SEND_MPLAYER_CMD, arg='pausing seek
+0.5')
EVENTS['video']['DOWN'] = Event(VIDEO_SEND_MPLAYER_CMD, arg='pausing
seek -0.5')
EVENTS['video']['REPLAY'] = Event(VIDEO_SEND_MPLAYER_CMD, arg='pausing
seek -0.1')
EVENTS['video']['SKIP'] = Event(VIDEO_SEND_MPLAYER_CMD, arg='pausing
frame_step +1.0')
# POWER is not a good choice :(
EVENTS['video']['POWER'] = Event(VIDEO_SEND_MPLAYER_CMD, arg='pausing
edl_mark')
and
MPLAYER_ARGS = {
...
'mpeg' : '-cache 8192 -subfont-text-scale 4 -utf8 -edlout /tmp/mpeg.edl',
...
}
The pausing keeps the video paused if it is already paused and not if
playing.
I would like to add you patch, it's nice and a good idea. Any chance of
you using the edl instead?

PS Please to add freevo-1 patches to the tracker, I'm away for the next
two weeks and will forget what has been said in the email lists.
