qwu16 972f28335a Added HEVC parser for WebRTC
This is part of effort to enable HEVC for WebRTC. Parser added here to support parsing of QP/picture size for bitstream, for dynamic adaptation and stream metadata abstraction.

// Example VPS can be generated with ffmpeg. Here's an example set of commands,
// runnable on Linux:
// 1) Generate a video, from the camera:
// ffmpeg -i /dev/video0 -r 30 -c:v libx265 -s 1280x720 camera.h265
//
// 2) Open camera.h265 and find the VPS, generally everything between the first
// and second start codes (0 0 0 1 or 0 0 1). The first two bytes should be 0x40
// and 0x01, which should be stripped out before being passed to the parser.
