Måns Rullgård	4693b031a3	Move H264 dsputil functions into their own struct This moves the H264-specific functions from DSPContext to the new H264DSPContext. The code is made conditional on CONFIG_H264DSP which is set by the codecs requiring it. The qpel and chroma MC functions are not moved as these are used by non-h264 code.

Michael Niedermayer	5820b90da0	Fix indention Originally committed as revision 22484 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2ce1c2e063	Always reset slice_table. Previously, the area of a lost slice would be left at the slice number of the previous frame which could occasionally match the number of the next slice and thus a non existing slice could have been used for prediction leading to additional decoding errors in otherwise undamaged slices.

Michael Niedermayer	145061a176	Fix a bunch of bugs ive introduced recently that broke threaded decoding. might also fix issue1788 Originally committed as revision 22141 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Janusz Krzysztofik	7c994c366c	Process picture aspect ratio changes in H.264. This fixes playback of such streams with ffplay (but does not affect current ffmpeg). Patch by Janusz Krzysztofik, jkrzyszt A tis D icnet D pl Originally committed as revision 22112 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	747db4e31a	Move init of right side of ref_cache from fill_caches() to init_the_darn_decoder(). Originally committed as revision 22071 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	358b5b1a59	Get rid of mb2b8_xy and b8_stride, change arrays organized based on b8_stride to ones based on mb_stride in h264. about 20 cpu cycles faster overall per MB Originally committed as revision 22065 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	662a5b2370	Reorder intra4x4_pred_mode so that we can read/write 4 values at once. 3-7 cpu cycles faster Originally committed as revision 22053 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	5b0fb5244d	Store intra4x4_pred_mode per row only. about 5 cpu cycles slower in the local code but should be overall faster due to reduced cache use. (my sample though has too few intra4x4 blocks for this to be meassureable easily either way) Originally committed as revision 22052 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	e1c88a2138	Cut the size of mvd_table by yet another factor of 2. The code read/write code itself was 1 cycle faster, overall its likely more due to cache effects Originally committed as revision 22048 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	c988f97566	Rearchitecturing the stiched up goose part 1 Run loop filter per row instead of per MB, this also should make it much easier to switch to per frame filtering and also doing so in a seperate thread in the future if some volunteer wants to try. Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample) This change also allows some optimizations to be tried that would not have been possible before.
