One easy way to get a MPEG-4 Video Elementary Stream file is to find 
a public MPEG-4 RTSP/RTP stream, and then run "openRTSP" on it.

If you search in Google for
         +"rtsp://" +".mp4"
then you'll find several "rtsp://" URLs that contain MPEG-4 video 
content.  You can try some of these (using "openRTSP" with the "-t" 
or "-T <http-port>" option (try 80, 8000 and 8080 for <http-port>).

E.g., run
         openRTSP -V -e 10 rtsp://christianchallenge.org/ccistream/sunday.mp4
(If you're behind a firewall, you may also need to add the "-t" 
option, to request that RTP be streamed over the TCP connection.)

This will give you two files: "video-MP4V-ES-1" and 
"audio-MPEG4-GENERIC-2".  Rename the file "video-MP4V-ES-1" as 
"test.m4v", and you will be able to use it in 
"testMPEG4VideoStreamer",  "testOnDemandRTSPServer", and 
"testMPEG4VideoToDarwin".  (Note that you don't really need to use a 
separate 'Darwin' server, because "testOnDemandRTSPServer" already 
has a built-in RTSP server.)
