2014-01-09mpegvideo: drop support for real (non-emulated) edgesAnton Khirnov
Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.
2013-11-15lavc: Edge emulation with dst/src linesizeRonald S. Bultje
Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.

2013-01-24wmv2: Propagate the wmv2 idct permutation type to the dsputils contextMartin Storsjö
This fixes encoding where the idct setting originally was set to FF_IDCT_AUTO and dsputil chose a default idct with a non-null permutation - even if the permutation tables were updated, dct_quantize in x86/mpegvideoenc_template.c also checked the value of this type variable.

2013-01-23Drop DCTELEM typedefDiego Biurrun
It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2013-01-21wmv2: move IDCT to its own DSP context.Ronald S. Bultje
This allows us to remove FF_IDCT_WMV2, which serves no practical purpose other than to be able to select the WMV2 IDCT for MPEG (or vice versa) and get corrupt output. Fate tests for all wmv2-related tests change, because (for some obscure reason) they forced use of the MPEG IDCT. You would get the same changes previously by not using -idct simple in the fate test (or replacing it with -idct auto).
2012-12-20lavc: introduce VideoDSPContextRonald S. Bultje
Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

2005-01-30In that patch:anonymous
- avctx and gb elements were removed from VC9Context, hence a larger diff - some code was added to h263dec.c regarding CODEC_ID_WMV3 (should apply to CODEC_ID_VC9 too) - VLC tables and other related tables were made global whenever this seemed necessary; appropriate changes were therefore made to other parts of the code using those tables - the change for the bitplane management to a struct (some of them should eventually be mapped to MpegEncContext arrays) wasn't associated with the proper frees; should be fixed now patch by anonymous better names for globalized tables by me Originally committed as revision 3905 to svn://svn.ffmpeg.org/ffmpeg/trunk
