How-To: Determine the maximum number of Reference Frames - Page 2

Shevach · 7th June 2010, 08:59

In the recent version of H.264 standard (dated 03/2009) the issue how to determine the maximal number of reference frames (or MaxDpbFrames) has been clarified and simplified.
For all profiles MaxDpbFrames equal to Min( MaxDpbMbs / ( PicWidthInMbs * FrameHeightInMbs ), 16 ), where MaxDpbMbs is taken from the table A-1.

imho should be X*Y*ReferenceFrames < 8388608 beyond that some sap player don't play or don't play correctly.
also for play with ps3 or x360 I suggest you use the appropriate preset in MeGUI.
