Jerome Borsboom	7a70879624	avcodec/vc1: remove unused overlap smooting and loop filter remove unused overlap smooting and loop filter Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>	7 years ago
Jerome Borsboom	ded52f6e36	avcodec/vc1: re-implement and expand VC-1 loop filtering The existing implementation did loop filtering for progressive frames only. This rewritten version implements loop filtering for all applicable frame types for both progessive and frame/field-interlace. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>	7 years ago

Jerome Borsboom	1160d1d478	avcodec/vc1: add bitstream elements for VAAPI VC-1 interlaced decoding We need to pass more bitstream elements to the VAAPI VC-1 decoder in order to start doing interlaced decoding in hardware. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>	7 years ago
Vittorio Giovara	41ed7ab45f	cosmetics: Fix spelling mistakes Signed-off-by: Diego Biurrun <diego@biurrun.de>	9 years ago
Luca Barbato	04d14c9b68	vc1: Split the decoder in components Speed up the overall compilation time.	11 years ago
Diego Biurrun	4d55e9de27	vc1: Split bits used in libavformat into a separate header This reduces inter-library dependencies.	11 years ago
Michael Niedermayer	64b98df389	vc1: simplify *_use_ic initialization Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	2cfccd8060	avcodec/vc1: Factorize imode enum out / remove duplication Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	c2f7417eeb	vc1: move MpegEncContext.resync_marker into VC1Context. The field still remains in MpegEncContext because it is used by the mpeg4 decoder.	11 years ago
Anton Khirnov	6792559f8a	vc1: use the AVFrame API properly.	11 years ago
Michael Niedermayer	728214992e	vc1dec: Remove interlaced warning Also add a note about the feature in the changelog. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	28243b0d35	vc1dec: Redesign the intensity compensation Use the intensity-compensated reference frame for subsequent fields/B-frames. Since we currently don't change the reference frame we have to maintain lookup tables for intensity compensation in the following dependent frames. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	93b1281264	vc1dec: Shuffle field MVs after decoding, not before This simplifies the code since copying MVs to the reference is not needed anymore (and maybe something about fixing artifacts). Also remove the unused mv_f_last. Fixes a small number of artifacts in black_screen_VC-1.mkv and several more artifacts in other videos. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	4162fc62b3	vc1dec: Do not allow field_mode to change after the first header This fixes out of array accesses. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	05f4c05061	vc1dec: remove interlaced warning While not yet bugfree, the warning is IMHO no longer appropriate Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	32a6dfeb12	vc1dec: drop mv_f_last, simplify code Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	782ebd6118	vc1dec: redesign the intensity compensation The existing implementation had little to do with VC1. This could be implemented by adjusting the reference frames ithemselfs but that would make frame multi-threading difficult. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	94ee7da08d	Remove pointless av_cold attributes in header files The init functions marked as av_cold have to be executed in any case, so there is no gain from trying to mark paths leading to such functions as unlikely.	12 years ago
Diego Biurrun	79dad2a932	dsputil: Separate h264chroma	12 years ago
Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Michael Niedermayer	7845f8d282	vc1dec: do not allow field_mode to change after the first header Fixes out of array accesses. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Alberto Delmás	ee769c6a7c	MSS2 decoder Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago
Kostya Shishkov	7627c35a81	vc1: export some functions This is a preparatory step for the MSS2 decoder which needs to use the WMV9 decoder to decode some kinds of frames. From the patch by Alberto Delmás <adelmas@gmail.com>	13 years ago
Michael Niedermayer	3b5ba60aa7	vc1dec: fix handling of max_coded dimensions Fixes Ticket1502 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Reimar Döffinger	6d797ac70f	VC1: Do not needlessly use signed types. This might even have prevented the compiler from some optimizations, since both signed and unsigned types are used for the dezigzag tables/ table pointers, and if a branches uses both the compiler needs to create more complex code. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Diego Biurrun	3c715383ea	vc1: Move init code shared between decoder and parser to common code file. This fixes standalone compilation of the VC-1 parser.	13 years ago
Ronald S. Bultje	c742ab4e81	vc1parse: call vc1_init_common(). The parser uses VLC tables initialized in vc1_common_init(), therefore we should call this function on parser init also. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Martin Storsjö	5f2c159c0f	vc1: Add ff_ prefix to nonstatic symbols Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Luca Barbato	1f948745c3	vc1: use an enum for Frame Coding Mode Document it a little and possibly fix a bug in dxva2_vc1.	13 years ago

Ronald S. Bultje	7d2e03afc8	vc1: make overlap filter for I-frames bit-exact.	14 years ago
Ronald S. Bultje	58bb6b7d93	wmv3dec: fix playback of complex WMV3 files using simple_idct. IDCT coefficients are read transposed, but simple_idct does not expect this. Therefore, only do tranposed coefficient reading if we're not using simple_idct. Fixes http://forum.videolan.org/viewtopic.php?f=14&t=89651	14 years ago

Kostya Shishkov	9e553f7acc	Print error message when true interlaced VC-1 frames are encountered to inform user why decoder produces no output. Originally committed as revision 20196 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
