[Mp4-tech] FW: H.264 reference picture question.

[Gary Sullivan]

Tarkan et al,
This is specified in a table in Annex A.  The memory capacity is a
function of the "Level" in use - you didn't say which Level(s) you're
interested in.  For example, Levels 4 and 4.1 require 4 frames (12,288
KBytes of memory) at their maximum supported frame size (8192
macroblocks per frame).  When operating at a smaller picture size than
the maximum supported frame size, the decoder needs to be able to use
the same memory capacity to store more of the smaller pictures (up to 16
frames).
Best Regards,
Gary Sullivan

	 Hi, 
	I need information about the maximum reference picture
requirement for H.264 decoding. 
	My real problem is I need to know how much memory space I need
to reserve for decoding H.264 without problem. 
	I need to decrease the required memory space for video decoding.
	Thanks in advance... 
	Tarkan
