* vc1: always read the bfraction element for interlaced fieldsHendrik Leppkes2012-01-26
| | | | | | | Previously, it would not be read if refdist_flag was not set, however according to the spec and the reference decoder, it should always be read. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
* vc1: don't read the interpfrm and bfraction elements for interlaced framesHendrik Leppkes2012-01-23
| | | | | | | This matches the spec as well as the reference decoder, and fixes a bug with interlaced frame decoding. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
* vc1: use an enum for Frame Coding ModeLuca Barbato2011-11-28
| | | | Document it a little and possibly fix a bug in dxva2_vc1.
* vc1: explicitly zero interlaced mode coding variables for progressive modeKostya Shishkov2011-10-13
| | | | | | | | 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>

* vc1: fix VC-1 Pulldown handling.John Stebbins2011-08-25
| | | | | | | | | | | | 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>

* doxygen: Prefer member groups over grouping into modulesReinhard Tartler2011-07-02
| | | | | | | | | 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.
* 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: 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.
* dsputil: move VC1-specific stuff into VC1DSPContext.Ronald S. Bultje2011-02-17
|
* logging: downgrade recoverable errors to warningsStefan Kost2011-02-08
| | | | | | | | 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>

* RES_SM in WMV3 is really two flags, so split it in decoderKostya Shishkov2010-09-26
| | | | Originally committed as revision 25208 to svn://svn.ffmpeg.org/ffmpeg/trunk
* 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
* 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
* Print error message when true interlaced VC-1 frames are encounteredKostya Shishkov2009-10-10

* 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
* Fix typo in vc1.c, make capitalization in warning/error messages more ↵Jason Garrett-Glaser2009-06-16
