Anton Khirnov	d9df93efbf	mpegvideo: simplify REBASE_PICTURE Always evaluate to NULL when the source Picture is not located in the MpegEncContext.picture array. That will only happen for next/last_picture_ptr when updating the thread context during h264 frame threaded decoding, where they will point to elements of ref_list. Since ref_list is not copied during updating the context and is invalid until it is constructed for the current slice, there is no point in doing anything complicated with next/last_picture_ptr, as they will get updated when the ref_list is filled.	12 years ago

Michael Niedermayer	cdc48860a8	h264: silence warning about array index being out of bounds The index is not out of bounds, adding an assert makes gcc realize this. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Ronald S. Bultje	8af915c21b	vp56: remove clear_blocks call, and clear alpha plane U/V DC only. The non-alpha and alpha-Y planes are cleared in the idct_put/add() calls. For the alpha U/V planes, we only care about the DC for entropy context prediction purposes, the rest of the data is unused. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Martin Storsjö	a65f965c04	mpegvideo: Do REBASE_PICTURE with byte pointers REBASE_PICTURE (more specifically, this half of it) takes a Picture pointer that points into one larger struct, finds the offset of that Picture within the struct and finds the corresponding field within another instance of a similar struct. The pointer difference "pic - (Picture)old_ctx" is a value given in sizeof(Picture) units, and when applied back on (Picture)new_ctx gets multiplied back with sizeof(Picture). Many compilers seem to optimize out this division/multiplication, but not all do. GCC 4.2 on OS X doesn't seem to remove the division/multiplication, therefore the new pointer didn't turn out to point to exactly the right place in the new struct since it only had sizeof(Picture) granularity (and the Picture is not aligned on a sizeof(Picture) boundary within the encompassing struct). This bug has been present before `47318953d` as well - with H264, pointers to h->ref_list[0][0] pointed to 88 bytes before h->ref_list[0][0] after the rebase. After shrinking Picture, the difference ended up even larger, making writes via such a Picture pointer overwrite other fields at random in H264Context, ending up in crashes later. This fixes H264 multithreaded decoding on OS X with GCC 4.2. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
