Hi. I want to set VDR to encode edited streams into .avi or .mpeg.

Can someone recommend an encoding type and method?

I have used mplayer's mencode, but never found a good setting for video and audio streams which plays well under WMP.

Well, no idea what WMP is, so...

For good file size and quality (for about 700MB per hour) what should I use?

mp3 audio? or just pcm? divx?

Bouah... no : aac for audio... and x264 for video :-)

Oh... I don't have windows here...

Thanks heaps Grégoire. I gather the you call that bash script from VDR directly? Where do you call it from??

No, from a shell :-)

Never used them. What's aac anyway, your script appears to use mp3?

What's the quality (with the same bitrate, of course) of x264 when compared to xvid/mpeg4?

I'm having some problems getting this script worked out. I still don't have 'faac' support, 'mplayer compiled without libmp3lame support, and 'x264encopts is not an MEncoder option'.

What syntax do you use?

./script.sh input.file ?? ?? output.file

Sorry - I've been trying, but am still away off getting encoding working!!

Thanks
