Javier Jardón	dba174906a	libs: declare _get_type() functions as const. ... Declaring a function as const enables better optimization of calls to the function. Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>	2012-07-19 15:19:17 +02:00
Gwenole Beauchesne	5975def8ab	mpeg2: allocate dummy picture for first field based I-frame. ... In P-pictures, prediction shall be made from the two most recently decoded reference fields. However, when the first I-frame is a field, the next field of the current picture could be a P-picture but only a single field was decoded so far. In this case, create a dummy picture with POC = -1 that will be used as reference. Some VA drivers would error out if P-pictures don't have a forward reference picture. This is true in general but not in this very specific initial case.	2012-04-02 11:36:56 +02:00
Gwenole Beauchesne	ac4fc0d36c	mpeg2: add new decoded picture buffer infrastructure. ... Decoded pictures are now maintained into DPB, similarly to H.264. The same mechanism could be re-used for VC-1 and MPEG-4:2 codecs.	2012-03-28 19:36:52 +02:00
