Anton Khirnov	9bd6375d5f	msrledec: check bounds before constructing a possibly invalid pointer, CC:libav-stable@libav.org	12 years ago
Anton Khirnov	238614de67	cdgraphics: do not rely on get_buffer() initializing the frame. Setting it to zero (instead of 128, as the default get_buffer() does) also produces more correctly-looking output.	12 years ago
Anton Khirnov	6ed9fc44ba	svq1: replace struct svq1_frame_size with an array. It is used as an array in svq1enc, so this is more correct.	12 years ago
Vladimir Pantelic	77bcb89600	vc1dec: use codec_id instead of codec_tag for VC1IMAGE the rest of the code is using codec_id everywhere already Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	12 years ago
Luca Barbato	b2a722a87e	sh4: drop unused functions {avg,put}_pixels4_c are not used.	12 years ago
Diego Biurrun	620289a20e	sh4: Fix silly type vs. variable name search and replace typo	12 years ago
Diego Biurrun	c9f933b5b6	Add av_cold attributes to arch-specific init functions	12 years ago
Diego Biurrun	25841dfe80	Use ptrdiff_t instead of int for {avg, put}_pixels line_size parameter. This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic.	12 years ago
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
Diego Biurrun	6c1a7d07eb	Use proper "" quotes for local header #includes	12 years ago
Diego Biurrun	4eef2ed707	ppc: fmtconvert: Drop two unused variables.	12 years ago
Anton Khirnov	f2960097e4	bink: fix a check for the first frame. Packet pts is a very unreliable indicator, use AVCodecContext.frame_number instead.	12 years ago
Diego Biurrun	52acd79165	x86: hpel: Move {avg,put}_pixels16_sse2 to hpeldsp	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
