Martin Storsjö	2866d108c9	vp8dsp: Remove the comment saying that the height is equal to the width This comment isn't true, the height can be different from the width for these functions (which is why the height is passed as a parameter to them). Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Janne Grunau	5f74bd31a9	vp8/armv6: mc: avoid boolean expression in calculation GNU as evaluates true as '-1' while Apple's variant and llvm's internal assembler evaluate it as '1'. The best way to avoid this madness is to eliminate boolean expressions instead of trying to fix it with preprocessor directives. Use a direct formula to calculate the required temporary space on the stack in ff_put_vp8_{epel,bilin}{4,8,16}_h[246]v[246]_armv6(). Fixes a checkasm segfault in vp8dsp.mc when using llvm's internal assembler for a non-Apple target.	9 years ago

Martin Storsjö	dc08bbf63a	vp8dsp: Clarify the first dimension of the mc function tables Index 0 is w=16, 1 is wd=8, 2 is wd=4. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Anton Khirnov	924e2ecd2b	qsvdec: when a frames ctx is supplied, use its frame dimensions The allocated frame size may be larger than the coded dimensions.	9 years ago
Anton Khirnov	92736c74fb	qsvdec: add support for P010 (10-bit 420) decoding	9 years ago
Anton Khirnov	ce320cf1c4	qsvdec: use the same mfxFrameInfo for allocating frames that was passed to DECODE_Init Stop duplicating this information.	9 years ago
Anton Khirnov	536bb17e96	qsvdec: make ff_qsv_map_pixfmt() return a MFX fourcc as well Stop hardcoding NV12. Also, move this function to the shared code, it will be used by the encoder as well.	9 years ago
Mark Thompson	221ffca631	vaapi_encode: Respect driver quirks around buffer destruction No longer leaks memory when used with a driver with the "render does not destroy param buffers" quirk (i.e. Intel i965).	9 years ago
Vittorio Giovara	6c445990e6	tiffenc: Check zlib support for deflate option during initialization This converts a misleading error about an option not found to a more meaningful one.	9 years ago
Vittorio Giovara	9f732e4c99	tiffenc: Check av_pix_fmt_desc_get() return value	9 years ago
Vittorio Giovara	d8f3b0fb58	targaenc: Move size check to initialization function In case of bogus input, fail early at codec initialization, rather than at the encode function.	9 years ago
Vittorio Giovara	eeb6849ced	rle: K&R formatting cosmetics	9 years ago
Diego Biurrun	326d911693	build: Drop unnecessary libavcodec <-> libavformat object dependencies	9 years ago
Diego Biurrun	e72d6fa08a	build: Move MP2 muxer declaration away from MP3 muxer code The MP2 muxer uses none of the code of the MP3 muxer.	9 years ago
Diego Biurrun	fe27792fd7	build: Move ff_mpeg12_frame_rate_tab to a separate file It is also used by the Dirac parsing code.	9 years ago
Diego Biurrun	8c929037ec	build: Add a new component for H.264 parsing code This fixes standalone compilation of the SVQ3 decoder, which had incomplete dependencies related to H.264 parsing.	9 years ago
Luca Barbato	3c08b7bc76	ffv1: Report additional bitstream information in verbose mode Useful to inspect samples.	9 years ago
Luca Barbato	fe6e5cbea7	ffv1: Remove version 2 and mark version 3 as non-experimental The encoder produces bitstream compatible with the current specification and version 2 is set as reserved (non-standardizable).	9 years ago
Martin Storsjö	82b7525173	Add an OpenH264 decoder wrapper While it is less featureful (and slower) than the built-in H264 decoder, one could potentially want to use it to take advantage of the cisco patent license offer. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Anton Khirnov	eccfb9778a	qsvdec_hevc: add the UID of the HEVC HW decoder plugin	9 years ago
Anton Khirnov	c67594a2c7	qsvdec_hevc: fix a variable name hevcenc -> hevcdec, this is a _decoder_ plugin.	9 years ago
Vittorio Giovara	7a745f014f	options_table: Add aliases for color properties All option names now match the ones provided by the av_color_*_name().	9 years ago
Vittorio Giovara	f172e22d6a	pixdesc: Add aliases to SMPTE color properties Drop ST from names and symbols, it does not add anything distinctive or descriptive.	9 years ago
Mark Thompson	8a62d2c28f	vaapi_encode: Maintain a pool of bitstream output buffers Previously we would allocate a new one for every frame. This instead maintains an AVBufferPool of them to use as-needed. Also makes the maximum size of an output buffer adapt to the frame size - the fixed upper bound was a bit too easy to hit when encoding large pictures at high quality.	9 years ago
Clément Bœsch	4a081f224e	libavcodec: fix constness in clobber test avcodec_open2() wrappers Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Martin Storsjö	0c9c4004ed	omx: Don't return > 0 from omx_encode_frame The encode function is supposed to just return 0 on success. This stems from a mixup with the return value of decode functions. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Martin Storsjö	31aa5335c3	libopenh264enc: Fix inconsistent whitespace Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Diego Biurrun	4f98bb7b6d	msmpeg4: Remove commented-out debug logging code	9 years ago
Diego Biurrun	eedbeb4c27	msmpeg4: Remove some broken, commented-out cruft	9 years ago
Diego Biurrun	3c84eaae9d	h264: Eliminate unused but set variable libavcodec/h264_slice.c:1384:9: warning: variable 'droppable' set but not used	9 years ago
Mark Thompson	11b8030309	vaapi_encode: Fix fallback when input does not match any format Just a typo. Add a comment to make it clearer what it's doing.	9 years ago
Martin Storsjö	8c3c7b8920	dxva2_h264: Remove an unused variable This was introduced by mistake in `39cdbb12aa` (only one of the added variables were really needed). Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Anton Khirnov	32c8359093	lavc: export the timestamps when decoding in AVFrame.pts Currently it's exported as AVFrame.pkt_pts, which is also the only use for that field. The reason it is done like this is that lavc used to export various codec-specific "timing" information in AVFrame.pts, which is not done anymore. Since it is confusing to the callers to have a separate field which is used only for decoder timestamps and nothing else, deprecate pkt_pts and use just AVFrame.pts everywhere.	9 years ago
Anton Khirnov	ad9c9440d5	qsvenc: support getting the session from an AVHWFramesContext	9 years ago
Anton Khirnov	a0524d9b1e	qsvdec: support getting the session from an AVHWFramesContext	9 years ago
Anton Khirnov	6f19bbcf85	qsvdec: move reading the user-provided session to qsv_decode_init() This is a more appropriate place for it.	9 years ago
Anton Khirnov	e85f6f7f8d	lavc: allow using AVCodecContext.hw_frames_ctx for decoding For now it will only be used by the default get_buffer2 callback for allocating hw frames.	9 years ago
Vittorio Giovara	40dd5166d2	truemotion2rt: Use ff_set_dimensions	9 years ago
Vittorio Giovara	a816432337	pixdesc: Add new SMPTE 431, 432, and 2085 color properties Appeared in H.264 2016/02. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Neil Birkbeck	5d560d38de	pixfmt: Add ARIB STD-B76 color transfer characteristic Adding hybrid log-gamma (https://en.wikipedia.org/wiki/Hybrid_Log-Gamma) based on the standardization in ARIB STD-B67: http://www.arib.or.jp/english/html/overview/doc/2-STD-B67v1_0.pdf The choice of enum value of 18 is consistent with HEVC: http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=10481 And also with latest proposal for color format in mkv: https://mailarchive.ietf.org/arch/search/?email_list=cellar&gbt=1&q=Colour+Format+proposal Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Anton Khirnov	58640fe89e	h264: handle frame recovery in h264_field_start() This is a more appropriate place for this. H264Context.recovery_frame is shared between frame threads, so modifying it where it is right now is invalid.	9 years ago
Anton Khirnov	e26c64148b	h264: discard slices of redundant pictures right after parsing the slice header Going through the whole decoder initialization process for a slice we are not going to decode is unnecessary and potentially dangerous.	9 years ago
Anton Khirnov	6efc463858	h264: always set redundant_pic_count during slice header parsing It is always checked in the surrounding code, so this make sure we don't see a value from an old slice.	9 years ago
Anton Khirnov	606fb6c032	h264: call the hwaccel frame_start() from h264_field_start() This is a more appropriate place for it.	9 years ago
Anton Khirnov	d1d7678040	h264: fix the check for mixed IDR/non-IDR slices	9 years ago
Anton Khirnov	b13fc1e344	h264: do not pass H264Context to h264_slice_header_parse() This should make it more clear that this function does not need any decoder-global state other than the parameter sets.	9 years ago
Anton Khirnov	996f13413b	h264: fix warnings in fill_filter_caches_inter() The code does some weird casting to a 2-dimensional sub-array of ref2frm. This is not necessary, since only one dimension is needed there.	9 years ago
Anton Khirnov	bc7f426851	h264: drop tests whether the codec id is AV_CODEC_ID_H264 Those are unused remnants of the old SVQ3 code.	9 years ago
