[Xia Frank]

Ross:
I am trying to send the created test.m4v file, but looks like it's too big
(>400kb), and still wait for approval. instead i attached log file and not
sure if it's useful.
Thanks
Frank

Frank,

Could you point me at (i.e., send the URL of) an example of one of the 
"test.m4v" files that you generated this way?  (Please *don't* send it via 
email, unless it's very small.)

>1. what's the MPEG4 elementary video stream

It's a file that contains MPEG-4 video data *only*.  I.e., it contains no 
extra header information (except for MPEG-4 "Visual Object Sequence" or 
"Visual Object" headers, which are needed).

>  and how can I generate it from my existing files like avi file?

If the video in the AVI file is already in MPEG-4 format, then I assume it 
would be possible (using some tool or another) to extract a 'raw' data 
track from an AVI file.  If so, you could probably get it this way.

You should use the latest version: currently "MPlayer v1.0pre3".  Of 
course, you will also need to use the "FFmpeg/libavcodec" library:
