Steven Walters	27237d524e	w32threads: support for frame multithreading Replace our incomplete w32threads implementation with x264's pthreads w32threads wrapper. Relicensed to LGPL with kind permission by Pegasys Inc. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Diego Biurrun	0249478756	doxygen: fix wrong comment syntax, //< vs. ///<	14 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Ronald S. Bultje	8dcf518430	vp3/theora: flush after seek.	14 years ago
Stefano Sabatini	975a1447f7	Replace deprecated FF__TYPE symbols with AV_PICTURE_TYPE_. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Ronald S. Bultje	8cf9a09d40	vp3-mt: fix deadlock when first frame is not a keyframe.	14 years ago
David Conrad	a89f4ca005	Fix VP3 edge emulation With negative stride, the start of the edge_emu buffer should be pointing to the last line, not the end of the buffer. With positive stride, pointing to the end of the buffer was completely wrong.	14 years ago
Jason Garrett-Glaser	902685b8ab	VP3: fix decoding of videos with stride > 2048 Also remove qscale_table code; this didn't make sense anyways as VP3 doesn't use an MPEG-like quantizer scale.	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

Alexander Strange	d23845f311	vp3: Frame-based multithreading support Decode times for big_buck_bunny_720p_stereo: 1 thread: real 1m14.227s user 1m13.104s sys 0m1.108s 2 threads: (33% faster) real 0m49.329s user 1m33.735s sys 0m1.834s 3 threads: (44% faster) real 0m41.593s user 1m44.884s sys 0m1.967s	14 years ago

Diego Elio Pettenò	d36beb3f69	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Alexander Strange	6ee99a7e13	VP3: remove an unnecessary static variable Originally committed as revision 26398 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	9d777508fa	Remove dead code in theora_decode_tables Reading 7 bits as an unsigned int can't result in a value exceeding 127. Accordingly, remove error message (as it'll never be reached). Originally committed as revision 25575 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	10f6915814	Reindent after r25573 Originally committed as revision 25574 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	1a48a57071	Fix Theora decoding bug if loopfilter is completely disabled Bug caused by the fact that get_bits(gb, 0) is undefined. Doesn't affect any streams generated by the official Theora encoder, but such streams are nevertheless valid. Fixes decoding of CELT-933dd833-nmr-bandt.ogv. Originally committed as revision 25573 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Reimar Döffinger	83f72f138e	Only draw the actually visible area in vp3_draw_horiz_band. Fixes a black line in non-swapped, non-mod-16-height Theora videos when vp3_draw_horiz_band is used. Originally committed as revision 25073 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Reimar Döffinger	3d487db153	Fix slice height for y position calculation for vp3_draw_horiz_band when the video uses 4:2:2 instead of 4:2:0 coding. Originally committed as revision 25052 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	3b9ee20f70	Fix vp3_draw_horiz_band to not produce completely chaotical values that result in overdrawing areas again and again if s->flipped_image is false. Originally committed as revision 25051 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	6974952d24	VP3/Theora: validate aspect and reduce it before exporting it via the context. Originally committed as revision 25050 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	6ce9b4310c	Remove use of the deprecated function avcodec_check_dimensions(), use av_check_image_size() instead. Originally committed as revision 24711 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands.

David Conrad	f50dafa8fc	vp3: avoid buffer overread in coeff decode I couldn't measure it to be slower for normal interframe videos. For the worst case, high-bitrate intra-only videos, it can be 0.7% slower. Originally committed as revision 22416 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
