* vc1: make overlap filter for I-frames bit-exact.Ronald S. Bultje2011-05-04

* vc1dec: use s->start/end_mb_y instead of passing them as function args.Ronald S. Bultje2011-05-04

* Revert "VC1: merge idct8x8, coeff adjustments and put_pixels."Ronald S. Bultje2011-05-04
| | | | | | | This reverts commit f8bed30d8b176fa030f6737765338bb4a2bcabc9. The reason for this is that the overlap filter, which runs after IDCT, should run on unclamped values, and thus IDCT and put_pixels() cannot be merged if we want to attempt to be bitexact.

* vc1: fix fate-vc1 after previous commit.Ronald S. Bultje2011-04-17
| | | | | | | | PROFILE_ADVANCED doesn't set res_fasttx, so make that a special case in the condition that decides which IDCT to use (and whether to read coefficients transposed or not). Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
* wmv3dec: fix playback of complex WMV3 files using simple_idct.Ronald S. Bultje2011-04-16
| | | | | | | | 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

* lavc: mark hurry_up for removal on next major bumpAnton Khirnov2011-04-02
| | | | | It has been deprecated for about five years, skip_idct/skip_frame should be used instead.
* vc1: make P-frame deblock filter bit-exact.Ronald S. Bultje2011-03-21

* vc1: slice support.Ronald S. Bultje2011-03-21
| | | | Also reset coded_block at each new slice, fixes problems in slice playback.
* vc1: fix up memleaks in the error codepath.Ronald S. Bultje2011-03-21
| | | | | Introduce end: and err: labels at the end of vc1_decode_frame(), which will clean up allocated memory consistently.

* VC1: merge idct8x8, coeff adjustments and put_pixels.Ronald S. Bultje2011-02-21
| | | | | Merging these functions allows merging some loops, which makes the results (particularly after SIMD optimizations) much faster.
* VC1: inline vc1_put_block() in vc1_decode_i_blocks().Ronald S. Bultje2011-02-21
| | | | | | Advantage is that it allows us to combine several loops into a single one, and these can eventually be merged into the IDCT itself. Also, it allows us to remove vc1_put_block(), and makes CODEC_FLAG_GRAY faster.
* VC1: don't use vc1_put_block() in vc1_decode_i_blocks_adv().Ronald S. Bultje2011-02-20
| | | | | | | | 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().

* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Make WMV3 decoder print more errors when decoding beta WMV9 files.Kostya Shishkov2010-07-10
| | | | | | 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

* 321l: do not use shifted s->linesize instead of correct s->uvlinesize.Kostya Shishkov2010-05-29
| | | | | | 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
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | 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
* Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini2010-03-30
| | | | | | is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk
* ff_msmpeg4_decode_init() calls ff_h263_decode_init() which callsKostya Shishkov2010-02-24
| | | | | | | | 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

* Use ff_msmpeg4_decode_init to initialize ff_msmp4_mb_i_vlc since staticReimar Döffinger2009-09-24
| | | | | | | | | 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
* Mark all pix_fmts and supported_framerates compound literals as const.Reimar Döffinger2009-09-06
| | | | | | 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

* Do not check for both CONFIG_VC1_VDPAU_DECODER and CONFIG_WMV3_VDPAU_DECODER,Diego Biurrun2009-07-29
| | | | | | the former depends upon the latter. Originally committed as revision 19532 to svn://svn.ffmpeg.org/ffmpeg/trunk

* VC-1/WMV: Remove redundant ff_init_block_index() calls.Jason Garrett-Glaser2009-06-17
| | | | | | | 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
* VC-1/WMV3 decoding: don't clear blocks unless they're actually used.Jason Garrett-Glaser2009-06-16
| | | | | | | | ~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
* idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall.Jason Garrett-Glaser2009-06-16
| | | | | | | | | 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
* Split decoder-specific code off from vc1.c into vc1dec.c and keep codeDiego Biurrun2009-06-11
