2020-03-14libavcodec, libpostproc: Remove outcommented START/STOP_TIMERAndreas Rheinhardt
as well as includes of libavutil/timer.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2019-09-28avcodec/ffv1enc: Fix out-of-bounds-array accessAndreas Rheinhardt
libavcodec/ffv1enc.c accessed an array of uint8_t [32] via array[0][j] in order to loop over all the uint8_t in this array of arrays. Of course this implied an out-of-bounds access for array[0] and UBSan complained about this. So replace this with nested loops; furthermore, factor this out into a function of its own to easily break out of the nested loops. This affected the FATE-tests vsynth1-ffv1, vsynth1-ffv1-v3-yuv420p, vsynth1-ffv1-v3-yuv422p10, vsynth1-ffv1-v3-yuv444p16, vsynth1-ffv1-v3-bgr0, vsynth1-ffv1-ffv1-v3-rgb48 as well as the corresponding vsynth2-*, vsynth3-* and the vsynth_lena-* tests.

used Temporarily keep the old method for ffmpeg_filters.c choose_pix_fmt and avfiltergraph.c pick_format() until a paletted pixel format without alpha is introduced. Signed-off-by: Marton Balint <cus@passwd.hu>
2018-04-24avcodec/ffv1enc: Check that the crc + version combination is supportedMichael Niedermayer
The crc flag is only stored since version 3 thus before this crcs do not work. We increase the version as needed same as we do with pix_fmts Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2018-03-10avcodec/ffv1: support of more pix_fmtJérôme Martinez
Without direct support of such pix_fmt, content is padded to 16-bit and it is not possible to know that the source file was with a smaller bit depth so framemd5 is different Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2018-01-12avcodec/ffv1enc: mark RGB48 support as non-experimentalJérôme Martinez
Resulting bitstream was tested with a conformance checker using the last draft of FFV1 specifications. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> Also the files are already in the wild, and decoder support is thus needed. And with decoders widely supporting it, there is no advantage in not allowing it in the encoder. The exact bitstream format may change in future versions of the spec, if improvments are found.

2016-10-25avcodec/ffv1enc: Fix storing RGB48 without explicitly set levelMichael Niedermayer
the bps value is only stored with level >= 1, using rgb48 with level 0 requires the user app to keep track of the bps by external means, which does not always happen also we force level >= 1 for other 16bps formats, so this is consistent.

2016-01-27avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPATDerek Buitenhuis
Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

2015-11-16ffv1: Explicitly name the coder typeVittorio Giovara
FFv1 uses two types of coders, golomb and range with two different tables. This is exposed this in a rather convoluted way, for example mentioning to set coder type 1 while initializing the variable 'ac' to 2, because encoder does not use range coder with default table. Appropriate internal coder type values have been added and used in any check rather than using raw numbers. Initialization of avctx.coder_type in ffv1dec is removed because this field is encoder only. An unneeded validation check in the encoder is dropped too.
