cH264Parser::cH264Parser | ( | void | ) |
Sets up a new H.264 parser.
This class parses only the data absolutely necessary to determine the frame borders and field count of the given H264 material.

Gets the next data byte.
If Raw is true, no filtering will be done. With Raw set to false, if the byte sequence 0x000003 is encountered, the byte with 0x03 will be skipped.

Parses the given Data, which is a sequence of Length bytes of TS packets.
The payload in the TS packets with the given Pid is searched for just enough information to determine the beginning and type of the next video frame. Returns the number of bytes parsed. Upon return, the functions NewFrame() and IndependentFrame() can be called to retrieve the required information.
Implements cFrameParser.
Reimplemented in cH265Parser.
