Michael Niedermayer	7845f8d282	vc1dec: do not allow field_mode to change after the first header Fixes out of array accesses. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	3a04c18d89	vc1dec: prevent null ptr dereferences. The added checks are in line with existing checks but should probably be replaced by more advanced error concealment at some point.

Mashiat Sarker Shakkhar	35a35d49d2	Double motion vector range for HPEL interlaced picture in proper place The existing code is not in the right place and it should cover both interlaced frame and field pictures. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Mashiat Sarker Shakkhar	eb657ecefd	vc1dec: Set opposite to the correct value for 1REF field pictures Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Mashiat Sarker Shakkhar	7cc3c4e1d4	vc1dec: Invoke edge emulation regardless of MV precision for 1-MV chroma This is required due to the way VC-1 handles chroma pull-back which may end up causing negative chroma MV for zero luma MV. Edge emulation needs to be invoked in such cases. This only affects vertical component of chroma motion vector. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Mashiat Sarker Shakkhar	88058d9a99	vc1dec: Set chroma reference field from REFFIELD for 1REF field pictures Interlaced field pictures can have one or two reference pictures, signaled by NUMREF syntax element. For single reference pictures, reference picture is determined by REFFIELD syntax element. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago

Kostya Shishkov	7627c35a81	vc1: export some functions This is a preparatory step for the MSS2 decoder which needs to use the WMV9 decoder to decode some kinds of frames. From the patch by Alberto Delmás <adelmas@gmail.com>	12 years ago

Mashiat Sarker Shakkhar	9cc74c9f6e	vc1dec: Remove separate scaling function for interlaced field MVs The scaling process for obtaining direct MVs from co-located field MVs is the same for interlaced field and progressive pictures. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	12 years ago
Mashiat Sarker Shakkhar	8379ea5e9f	vc1dec: Invoke edge_emulation regardless of MV precision In VC-1 interlaced field pictures, chroma motion vectors can extend beyond picture boundary even if luma vectors are bounded. The problem shows up only for hpel interpolated MVs, and may be due to the way motion vectors are scaled / cropped. Thanks to Konstantin Shishkov for suggesting the fix. This fixes long-known segfaults in MC-VC1.ts from videolan streams archive. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	12 years ago
