◆ FindMPEG2Keyframes()

bool DTVRecorder::FindMPEG2Keyframes ( const TSPacket * tspacket )

protected

Locates the keyframes and saves them to the position map.

This searches for three magic integers in the stream. The picture start code 0x00000100, the GOP code 0x000001B8, and the sequence start code 0x000001B3. The GOP code is prefered, but is only required of MPEG1 streams, the sequence start code is a decent fallback for MPEG2 streams, and if all else fails we just look for the picture start codes and call every 16th frame a keyframe.

NOTE: This does not only find keyframes but also tracks the total frames as well. At least a couple times seeking has been broken by short-circuiting the search once a keyframe stream id has been found. This may work on some channels, but will break on others so algorithmic optimizations should be done with great care.

PES header format
byte 0  byte 1  byte 2  byte 3      [byte 4     byte 5]
0x00    0x00    0x01    PESStreamID  PES packet length

Returns: Returns true if packet[s] should be output.
