[Live-devel] Implementing error correction

[Ross Finlayson]

>1. Should I be using the TransportStream instead of the ProgramStream?

I don't know enough about your proposed FEC scheme to say for sure, but if 
you're planning to use it only for video frames, then it sounds like you 
should be using Program Streams, because they are easier than Transport 
Streams to generate the video Elementary Stream from.

>2. Does the MPEG1or2VideoStreamFramer return MPEG Video Frames
>(I,P,B)?

No.  It returns parts of frames: headers - Video Sequence Headers, GOP 
Headers, Picture Headers - and slices.

Yes, because (as noted above) the "MPEG1or2VideoStreamFramer" returns 
discrete slices (and headers), you should be able to process them fairly 
easily.
