MPEG Headers Quick Reference

This is a quick reference to the various headers and streams found in MPEG/DVD. For a complete description you should get a copy of ISO/IEC 13818.

Video Formats and Quality

有人在說YUV有人在講YCbCr

一般在網路上查詢 Ring effect，都會出現日環蝕的那個 Ring effeect。總是查不到 video processing 裡面的 Ring effect!

Pictures are coded and decoded in a different order than they are displayed.

This is due to bidirectional prediction for B pictures.

GStreamer is an extremely powerful and versatile framework for creating streaming media applications.

  it use GObject,glib,etc.
