[MEncoder-users] Greetings

[James Hastings-Trew]

Hi, I'm new to the mailing list. Sorry if this has been asked and 
answered, but searches turned up nothing, and the documentation at 
http://www.mplayerhq.hu/DOCS/HTML-single/en/MPlayer.html seems a tad out 
of date in regard to this question.

Basically, I am trying to get Mencoder to produce a working .MP4 file at 
480x272 that will work on the Sony PSP. I know it is possible - there 
are at least 2 commercial programs that I am aware of that use Mencoder 
as their background encoding engine that do this - CloneDVD Mobile (on 
the PC) and VisualHub (on the Mac).

I've followed the guide in the documentation 
http://www.mplayerhq.hu/DOCS/HTML-single/en/MPlayer.html#menc-feat-quicktime-7 
which did not produce a file that either Quicktime or the PSP would look 
at. If Quicktime won't play it, neither will the PSP, so I figured this 
would be a place to start.

This current command line gets me a file that Quicktime will play but 
there is no video - just a black screen.

mencoder dvd://1 -chapter 1-1 -vf scale=480:272 -oac faac -faacopts 
br=128:mpeg=4:object=2:raw -ovc x264 -x264encopts bitrate=700 -of lavf 
-lavfopts format=psp -o testpsp.mp4

Note that I have left off all -x264 encoding options because I am just 
trying to get a baseline command that works, and then I can add all the 
fiddly bits later. The manual makes mention of a "globalheader" option 
for the -x264encopts which is supposed to be there (according to the 
manual) but Mencoder spits this out as an unknown option:

My question is, does anyone have an x264 encoding comand line that 
works? Or can someone point me to a current, working guide? Thanks.
