Hi All,
I've searched and searched but I can't seem to find out conclusively if mencoder can encode .m2v/.mpv/.mv2 files, i.e. elementary video so I can use directly in Muxman or DVDAuthor without having to demux first.
If there a special format switch available?
TIA,

Thanks Immersion!
I just replaced
-of mpeg -mpegopts format=dvd
with
-of rawvideo -ffourcc MPG2
and it works!
By the way, if I want to also encode audio what switches would I use in conjunction with this? I am using ac3.
TIA

you wouldn't.
mencoder can't output streams with audio only.
unless you want to create a ps muxed with ac3,
but then why ask about outputing elementary streams
use aften to encode to ac3,
or ffmpeg for simplicity

Thanks again Immersion,
The reason I asked is that I have found mencoder to be a little faster than ffmpeg - I have used ffmpeg to produce .m2v and .ac3 files ready for dvd authoring. To make sure I understand: I can use mencoder to create a DVD compliant elementary video stream and then I can extract the audio (Vdub/Avidemux) to wav and use aften to convert to ac3? Then I just use Muxman or DvdAuthor.

Yes,
no reason not to continue using ffmpeg for the audio.
you're familiar with it, why not?
could also use mplayer to get the wav.
