Hi Ross

Here is the link of mpeg-4 program stream file:

I tried to use existing code to convert this file. It seems only audio
portion of the PS file works.

I think that the current code will work for MPEG-4, perhaps with some small 
changes.  (E.g., you may need to make some changes to the "stream_id" 
testing in "MPEG2TransportStreamFromPESSource::afterGettingFrame1()".

If you could point me at an example of a "MPEG-4 Program Stream" file, then 
that would be useful.
