Hey All,

I have been working on a problem with trying to splice data into a live MPEG2 stream (or even a file based MPEG2 stream) on the fly. I've been playing with programs such as dvbsnoop and vktools but from the output that i get, i'm not entirely sure what i'm looking at. The basics that i am looking for is the ability to see iframes (or at least detect when they hit), and the ability to tell when i can include a new splice into the existing stream from another source.

Optimally I am looking for the ability to play a file from my hard drive that has a full TS stream, detect a commercial, and splice over the top of it with another file based MPEG2 stream.

Any information that you guys can point me to would be great.
