[MEncoder-users] Creating WMP Mobile Compatible Videos

[Gordan Bobic]

Hi,

I'm struggling to create video files that are actually playable on my WM 
based phone using the Windows Media Player Mobile (both v10/WM5 and 
v11/WM6).

The video I make using the phone itself works on the build in WMPM 
(obviously) and here is what mplayer reports about it:

So, the relevant bits seem to be:
mp4v, mpeg4, and 3gpp. I've not had any luck in producing 3gpp format, 
but I have tried this:

mencoder -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1000 -ffourcc mp4v 
-of lavf -lavfopts format=mp4 -nosound -o /tmp/test.mp4 test.mkv

but WMPM flatly refuses to play it. Has anybody managed to produce a 
video file playable on Windows Media Player Mobile using mencoder?

I know I can just use tcpmp or another player to play it, but I would 
rather like to have the means of producing a video file playable without 
the need to use a 3rd party player. How can I produce the video in the 
same format as the one that works?

TIA.

Gordan
