[mythtv-users] Transcoding for Sony PSP with thumbnail

I've been playing around with transcoding video for the PSP to watch on the way
to work. To recap so far, to convert direct from a nuv to the MP4 file, I do
the following:
ffmpeg -y -i /mythtv/recordings/1084_20050703130500_20050703140500.nuv -bitexact
-f psp -s 320x240 -r 29.97 -b 512 -acodec aac -ac 2 -ar 24000 -ab 32

What I've just been doing, is working on creating the thumbnail to go with this:
mplayer -vo jpeg -frames 2
mogrify -geometry 160x120! 00000001.jpg
mv 00000001.jpg /mythtv/video/M4V10001.THM

So, when both files get copied over to the PSP, you should now get the video
with a thumbnail.

Quick question - does anyone know how to get mplayer to capture an image at
frame 100, or something like that?

Now I've just got to work on getting the title, as I current see all files
called M4V10001.MP4 (or something similar), and I'd like to preserve the
programme title information.

Hope this is of use to somebody
