Reimar Döffinger	c614d32e22	Fix invalid reads in VC1 decoder Patch discussed and taken from https://roundup.ffmpeg.org/issue2584 (cherry picked from commit `2bbec1eda4`)	14 years ago
Ronald S. Bultje	70aa916e46	VC1: don't use vc1_put_block() in vc1_decode_i_blocks_adv(). Advanced profile never uses "range reduction", so vc1_put_block() quite literally just calls put_pixels_clamped() from vc1_decode_i_blocks_adv(). By inlining the function, we can prevent calling IDCT8x8 if CODEC_FLAG_GRAY is set, and we don't have to scale the coeffs in the [0,256] range, but can instead use put_signed_pixels_clamped().	14 years ago

Diego Elio Pettenò	e7e2df27f8	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `d36beb3f69`)	14 years ago

Kostya Shishkov	cba322d76d	Make WMV3 decoder attempt to decode WMVP as well Originally committed as revision 25209 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
David Conrad	fca58a815a	vc1: Fix ordering of loop filter for I/B frames All horizontal edges must be filtered before all vertical edges Originally committed as revision 24206 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	3683b7e570	vc1: ff_draw_horiz_band needs a one row delay when the loop filter is active Originally committed as revision 24205 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	42ff9d7a58	Make WMV3 decoder print more errors when decoding beta WMV9 files. As a side effect it will also decode a lot of P-frames from those. Originally committed as revision 24161 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	0724a674fc	Change type of zz_table to uint8_t to match the scantables it points to. Originally committed as revision 23831 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	1c100b1367	321l: do not use shifted s->linesize instead of correct s->uvlinesize. This should fix chroma issues in WMV3/VC-1 decoder with avfilter enabled. Originally committed as revision 23370 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	d2df291f73	ff_msmpeg4_decode_init() calls ff_h263_decode_init() which calls MPV_common_init(), so calling both is redundant and leads to memory leaks in WMV3/VC-1 decoder. Thus use only the first function in WMV3/VC-1 decoder initialization. Originally committed as revision 22024 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	d68b27a95d	VC1: fix missing include h263.h Originally committed as revision 21932 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	261a3c2d05	Move AVCodecs from h263dec.c to msmpeg4.c and disentangle init decode init. Originally committed as revision 21102 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	53b04467ae	Warn when WVC1 cannot be decoded Originally committed as revision 20201 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Andrew Dennison	95ce961d88	Since some junk may be or may be not present before actual VC-1 extradata, search for real extradata start instead of always skipping one byte. Patch by Andrew Dennison gmailify(${name}d, lists) Thread: [PATCH] Fix VC1 "Incomplete extradata" for mkv files generated by eac3to Originally committed as revision 20178 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	c05df6895f	Use ff_msmpeg4_decode_init to initialize ff_msmp4_mb_i_vlc since static VLC tables should only be initialized from one place. This initializes/calculates more VLC tables than necessary for VC1 decoding, but this is only done once and only a small overhead in time and space (maybe 30 kB) it seems not worth adding a separate function. Originally committed as revision 20010 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	2ba8301769	Mark all pix_fmts and supported_framerates compound literals as const. Makes no difference for gcc but at least icc can put them in .rodata then. Originally committed as revision 19789 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	700363afe7	Only enable WMV3 decoder when it has been turned on in the build system. Originally committed as revision 19534 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	e0f58e39c4	Do not check for both CONFIG_VC1_VDPAU_DECODER and CONFIG_WMV3_VDPAU_DECODER, the former depends upon the latter. Originally committed as revision 19532 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	74a30595b2	Edge emulation should be used in B-frame MC in mspel mode with mv_x < 1 or mv_y < 1. Originally committed as revision 19255 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	351653a51e	VC-1/WMV: Remove redundant ff_init_block_index() calls. These are only supposed to be called once per row, not once per macroblock. ~1.5% faster according to oprofile. Originally committed as revision 19213 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	010f98f96a	VC-1/WMV3 decoding: don't clear blocks unless they're actually used. ~8% faster VC-1 decoding. Possible future optimization: clear blocks after use instead of before, and for DC-only blocks, only clear the DC coefficient. Originally committed as revision 19205 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	4f717c69ed	idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall. Includes mmx2 asm for the various functions. Note that the actual idct still does not have an x86 SIMD implemtation. For wmv3 files using regular idct, the decoder just falls back to simple_idct, since simple_idct_dc doesn't exist (yet). Originally committed as revision 19204 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	b761659bef	Split decoder-specific code off from vc1.c into vc1dec.c and keep code shared between decoder and parser in vc1.c. Originally committed as revision 19152 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Baptiste Coudurier	35b2c65756	vc1 and wmv3 decoders use MPV_frame_start which uses get_buffer, set CODEC_CAP_DR1 Originally committed as revision 19111 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Baptiste Coudurier	87e302bfd8	remove unused hack which set AVCodecContext frame_number to pic timestamp Originally committed as revision 18988 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Baptiste Coudurier	2d05bc8641	set pict_type in VC-1 parser, fix some timestamps problems Originally committed as revision 18987 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
David Conrad	ebcf3b742b	Ensure that we don't read from invalid memory with B-frame qpel Originally committed as revision 18839 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Benjamin Larsson	10c773c12f	Remove dead assignments found by CSA Originally committed as revision 18730 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	b750fb6945	Display dimensions should not affect the real size of coded frame, thus set only avctx->{width,height} and don't touch coded_{width,height} when parsing them. This fixes the case when coded and display dimensions differ by more than one macroblock. Originally committed as revision 18665 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	21fce71fd1	Switch VLC tables in WMV3/VC-1 decoder to new static init method Originally committed as revision 18658 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Kostya Shishkov	346802aa99	Remove some useless assignments and variables found by Clang Originally committed as revision 18638 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
David Conrad	2d08f9ea54	VC1 loop filter uses the frame quantizer not the mb quantizer Originally committed as revision 18534 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
David Conrad	3992526b3c	Split VC1 loop filter into separate functions for h/v and size Originally committed as revision 18521 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
David Conrad	0e58865d6e	Move VC1 loop filter to DSPContext Originally committed as revision 18520 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

David Conrad	c374691b28	Rename put_no_rnd_h264_chroma* to reflect its usage in VC1 only Originally committed as revision 18517 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
David Conrad	6cecd63005	VC1: Do qpel when needed for both MVs in a B frame Originally committed as revision 18511 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
