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
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	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

Christophe Gisquet	6ee7681723	huffyuvenc: write last odd sample If width is odd, last sample wouldn't be written. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Christophe Gisquet	1467780772	huffyuvenc: add a non-deterministic option Not actually used in huffyuvenc, but rather in setting the frame threading. Example for some files: context=0: 851974 27226 1137281 context=1,ND=0: 471819 22604 972351 context=1,ND=1: 472875 22673 972582 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Diego Biurrun	c67b449beb	dsputil: Split bswap*_buf() off into a separate context	11 years ago
Christophe Gisquet	e7fc5d53a0	huffyuv: change statistics initialization Normally, a Laplace distribution is more typical of the residuals encoded, but for noisy input, it's both better and simpler to be safe and use a 1/d^2 distribution. Second hunk could use some renormalization but it has effectively little impact. Output size of ffvhuff on various 4:2:0 sequences: context=0,1/d: 851974 27226 1137281 context=0,1/d²: 619081 25069 1051500 context=0,1/d³: 501983 30454 1290561 context=0,lapl: 500650 31754 1304082 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	334aafe565	avcodec/huffman/ff_huff_gen_len_table: support skiping stat=0 entries This is probably not the simplest solution but as this is needed for a bugfix, simplification is left for later. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
