2011-10-13vc1: explicitly zero interlaced mode coding variables for progressive modeKostya Shishkov
Both v->fcm and v->field_mode are used in common code, now they won't be reset for progressive frame after interlaced one causing writing past the frame end for example. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

2011-08-25vc1: fix VC-1 Pulldown handling.John Stebbins
Pulldown flags are being set incorrectly and AVFrame->repeat_pict is not being set. Also, skipped frames exit header parsing too early and do not set pulldown flags appropriately. Ticks_per_frame needs to be set and time_base adjusted so player can extend frame duration by a field time. This fixes problems encountered when attempting to transcode HD-DVD EVOB files with HandBrake. Also makes these files play smoothly in avplay. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

2011-07-02doxygen: Prefer member groups over grouping into modulesReinhard Tartler
Before this, almost all module groups have been used for grouping functions and fields in structures semantically. This causes them to not appear properly in the file documentation and needlessly clutters up the "Modules" index. Additionally, this commit streamlines some spelling and appearances.
2011-05-04Revert "VC1: merge idct8x8, coeff adjustments and put_pixels."Ronald S. Bultje
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.

2011-02-21VC1: merge idct8x8, coeff adjustments and put_pixels.Ronald S. Bultje
Merging these functions allows merging some loops, which makes the results (particularly after SIMD optimizations) much faster.
2011-02-18dsputil: move VC1-specific stuff into VC1DSPContext.Ronald S. Bultje
2011-02-08logging: downgrade recoverable errors to warningsStefan Kost
In all 3 cases, the decoding continues and thus a warning would be sufficient. Helps application that catch them with own log handers to handle them accordingly. Signed-off-by: Mans Rullgard <mans@mansr.com>
2010-09-26Make WMV3 decoder attempt to decode WMVP as wellKostya Shishkov

2010-09-26RES_SM in WMV3 is really two flags, so split it in decoderKostya Shishkov
Originally committed as revision 25208 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-10Make WMV3 decoder print more errors when decoding beta WMV9 files.Kostya Shishkov
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
2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
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

2009-06-16idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall.Jason Garrett-Glaser
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

2009-04-23Display dimensions should not affect the real size of coded frame, thus setKostya Shishkov
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

2009-04-07Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames.
