Thanks John, code looks nice at first glance. I'll test it now.

Adjust keyframe offset for dtvrecorder buffering

Added dtvrecorder-fix-h264offset.patch to account for internal dtvrecorder buffering.

Small suggestion. It would probably be quite useful, in the short term at least, to add the ability to debug/log the stream info - numbers of slices, NAL types etc.
Regardless, I'll test on my local HD station.

New version, which includes and supersedes all previous patches on this ticket.

H264parser-v1.1.patch has some minor cleanups. It also will not return the first keyframe until a IDR frame has been seen. It also adds the basic hooks into avformatdecoder, which the first version failed to do.
