Andreas Rheinhardt	6bf99f8c93	avcodec/huffyuv: Update outdated link Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Andreas Rheinhardt	566280c3f4	avcodec/huffyuv: Split HYuvContext into decoder and encoder context While the share of elements used by both is quite big, the amount of code shared between the decoders and encoders is negligible. Therefore one can easily split the context if one wants to. The reasons for doing so are that the non-shared elements are non-negligible: The stats array which is only used by the encoder takes 524288B of 868904B (on x64); similarly, pix_bgr_map which is only used by the decoder takes 16KiB. Furthermore, using a shared context also entails inclusions of unneeded headers like put_bits.h for the decoder and get_bits.h for the encoder (and all of these and much more for huffyuv.c).

Andreas Rheinhardt	83a8b9fac7	avcodec/huffyuv: Inline ff_huffyuv_common_init() in its callers This is in preparation for splitting HYuvContext. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Andreas Rheinhardt	2415f5158b	avcodec/huffyuv: Use AVCodecContext.(width\|height) directly These parameters are easily accessible whereever they are accessed, so using copies from HYuvContext is unnecessary. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago

Martin Storsjö	87a814fdce	libavcodec: Add missing AVClass pointers This fixes crashes since `243df1351`. Signed-off-by: Martin Storsjö <martin@martin.st>	9 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

Michael Niedermayer	b53aab1a58	libavcodec/huffyuv: >8 bit support This adds only yuv420p10, others are trivial to add after this commit and will be added in a subsequent commit. Currently the implementation is not optimized, optimizations will be added later Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
