Michael Niedermayer	70dc6bbf1b	avcodec/svq1enc: Clear MMX state after svq1_encode_plane() svq1_encode_plane() uses SIMD and we call libc memory allocation functions after it Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago

Andreas Cadhalpun	9079e99d2c	svq1enc: fix out of bounds reads level can be 5, but there are only four codebooks. Fixes ubsan runtime error: index 5 out of bounds for type 'int8_t [4][96]' Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	9 years ago

Vittorio Giovara	059a934806	lavc: Consistently prefix input buffer defines Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Vittorio Giovara	4b6b1082a7	lavc: Deprecate avctx.me_method This option is extremely codec specific and only a few codecs employ it. Move it to codec private options instead: mpegenc family supports only 3 values, xavs and x264 use 5, and xvid has a different metric entirely.

Michael Niedermayer	e36db49b7b	avcodec: Add a min size parameter to ff_alloc_packet2() This parameter can be used to inform the allocation code about how much downsizing might occur, and can be used to optimize how to allocate the packet Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Michael Niedermayer	c40ecffd31	Replace AV_PKT_DATA_QUALITY_FACTOR by AV_PKT_DATA_QUALITY_STATS The stats are a superset of the quality factor, also allowing the picture type and encoder "PSNR" stats to be exported This also replaces the native by fixed little endian order for the affected side data AV_PKT_DATA_QUALITY_FACTOR is left as a synonym of AV_PKT_DATA_QUALITY_STATS Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Vittorio Giovara	40cf1bbacc	Deprecate avctx.coded_frame The rationale is that coded_frame was only used to communicate key_frame, pict_type and quality to the caller, as well as a few other random fields, in a non predictable, let alone consistent way. There was agreement that there was no use case for coded_frame, as it is a full-sized AVFrame container used for just 2-3 int-sized properties, which shouldn't even belong into the AVCodecContext in the first place. The appropriate AVPacket flag can be used instead of key_frame, while quality is exported with the new AVPacketSideData quality factor. There is no replacement for the other fields as they were unreliable, mishandled or just not used at all. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Vittorio Giovara	5d3addb937	Add a quality factor packet side data This is necessary to preserve the quality information currently exported with coded_frame. Add the new side data to every encoder that needs it, and use it in avconv. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Vittorio Giovara	d6604b29ef	Gather all coded_frame allocations and free functions to a single place Allocating coded_frame is what most encoders do anyway, so it makes sense to always allocate and free it in a single place. Moreover a lot of encoders freed the frame with av_freep() instead of the correct API av_frame_free(). This bring uniformity to encoder behaviour and prevents applications from erroneusly accessing this field when not allocated. Additionally this helps isolating encoders that export information with coded_frame, and heavily simplifies its deprecation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago

Michael Niedermayer	404fe63e23	avcodec: Pass PutBitContext into ff_h263_encode_motion() instead of MpegEncContext This avoids the need to dereference MpegEncContext->pb if it is already available outside ff_h263_encode_motion() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

wm4	f6774f905f	mpegvideo: operate with pointers to AVFrames instead of whole structs The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago
