Gwenole Beauchesne	fa37cf0db3	H.264: move avctx->{profile,level} init before AVCodecContext.get_format(). Originally committed as revision 22884 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Gwenole Beauchesne	b08e38e8c3	H.264: move avctx->refs init before AVCodecContext.get_format(). Originally committed as revision 22883 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	d02bb3ecf1	Move static function fill_filter_caches() from h264.h to h264.c. The function is only used within that file, so it makes sense to place it there. This fixes many warnings of the type: h264.h:1170: warning: ‘fill_filter_caches’ defined but not used Originally committed as revision 22876 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alexander Strange	7a5c850be9	H264: Copy h264dsp when creating new slice threads Fixes slice multithreading (broken in r22565) Fixes issue1815 Originally committed as revision 22740 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	1052b76f0f	Fix implicit weight for b frames in mbaff. Originally committed as revision 22733 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stephen Warren	3bccd93ac0	Set VDPAU H264 picture parameter field_order_cnt and frame_num at the start of decoding a picture instead of at the end. Fixes mmco01.264 Patch by Stephen Warren Originally committed as revision 22728 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	6f2c72c126	Remove unused variable, fixes the warning: libavcodec/h264.c:1562: warning: unused variable `s' Originally committed as revision 22647 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Janusz Krzysztofik	5388f0b479	Reinitialize the h264 decoder context on every valid aspect ratio change, not only size changes. Patch by Janusz Krzysztofik foo=zyszt <jkr$foo@tis.icnet.pl>. Originally committed as revision 22597 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
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. Originally committed as revision 22565 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
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. Originally committed as revision 22483 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	3d9137c883	Reorder indexes in weight tables. 5 cpu cycles faster. Originally committed as revision 22183 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	1a29c6a0bb	cosmetic addition of {} Originally committed as revision 22178 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	72f86ec013	Simplify implicit_weight table init. Originally committed as revision 22168 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
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
Aurelien Jacobs	bc99737689	revert r22112 which broke playback of cathedral-beta2-400extra-crop-avc.mp4 Originally committed as revision 22125 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	d43c192236	Keep mvd_table values of only 2 mb rows. Originally committed as revision 22047 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	b5bd070029	Change mvd_cache & mvd_table to 8bit, this is overall a bit faster for high resolution videos. about 20cycles faster per MB for cathederal. Originally committed as revision 22038 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	db8cb47d15	Try to set has_b_frames in codec init if we know everything alraedy. This fixes some issues with the first few timestamps. Originally committed as revision 21976 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	69a28f3e2b	Move predict_field_decoding_flag() from h264.h to .c as its only used there and belongs there as well. Originally committed as revision 21861 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	69cc31832f	Move check for and call of predict_field_decoding_flag() from the mb code to the row code. This function would only be needed on a MB basis for MBAFF+FMO Originally committed as revision 21860 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
