Laurent Aimar	4e06acbde4	Fixed a segfault in the DCA decoder with corrupted streams. It happens when the number of channels defined by DCAContext:acmod is lower than DCAContext:prim_channels. In this case, dca_subsubframe() will call qmf_32_subbands() using s->channel_order_tab[] entries equal to -1. Originally committed as revision 22083 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	4784b0922f	Do not read beyond end of input in EA-TGV. This should avoid FATE test #362 result depending on uninitialized data. FATE result may change for this test. Originally committed as revision 22082 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Martin Storsjö	50ff78db01	RTSP muxer: Use a local copy of the AVPacket for sending to the chained muxer This way, we avoid overwriting stream_index in the user's AVPacket with a nonsense value. Originally committed as revision 22081 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	cf41a02b1b	Only load the topleft mv/ref when the topright is unavailable. 8 cpu cycles faster. Originally committed as revision 22079 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	cf7b67bc40	Remove some useless operations from the code setting left_cbp. maybe 0.5 cpu cycles faster Originally committed as revision 22078 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Francesco Cosoleto	6abda15f56	Prevent overflow of start_time + recording_time. Patch by Francesco Cosoleto gmail($name) Originally committed as revision 22077 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Peter Ross	be707647e9	Add myself as maintainer of the bink demuxer and bink audio decoder Originally committed as revision 22075 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	59b5370f02	Simplify code to set cbp_* this seems 1 cpu cycle slower even though we practically just remove code. Speed loss seems caused by the merge of if(left_type), iam commiting this anyway as i cant imagine this to be anything but compiler messup. Originally committed as revision 22073 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Benoit Fouet	5818418758	Fix typos in ref_index documentation. Originally committed as revision 22072 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	77c6edb846	Remove 3 mv_cache zeroing instructions that zeroed the right side. This seems unneeded as nothing seems to ever set it to non zero values. Originally committed as revision 22070 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	8f8497ae78	Remove useless check of the 2 left MBs of a pair being in the same slice. Originally committed as revision 22069 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	aa5ee59eee	Simplify code in mv_pred. Not benchmarked as this is petty much just code removial. Originally committed as revision 22066 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
Måns Rullgård	f3a572ca14	Disable suffix rules Most of the make builtin rules, which we do not need, are suffix rules, and we use only new-style pattern rules. Disabling suffix rules saves some time when building on slow systems. Originally committed as revision 22064 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	479e1e6170	Remove pointless empty line. Originally committed as revision 30730 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago

Stefano Sabatini	11ab237e31	Add the graph2dot tools and document it. Also link avfiltergraph.o and graphparser.o against libavfilter, as it uses them. Originally committed as revision 22063 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	9c16add67b	Replace not anymore valid syntax "-title X" with "-metadata title=X". Originally committed as revision 22062 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	3b606e71c4	svq3 now in working condition, at least vissually, ill let fate tell us if the checksums match Originally committed as revision 22061 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	fc7f7f171f	fix compilation, sorry ive not checked cvslog for a while :((( svq3 decoder does not work yet though but i didnt want to keep compilation broken longer Originally committed as revision 22060 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Anton Khirnov	cba2f6d51b	asfenc: write tags in proper UTF-16. Patch by Anton Khirnov wyskas gmail com Originally committed as revision 22059 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Anton Khirnov	e4ea625ab0	asfdec: don't strip the "WM/" prefix, this should be done during conversion. Patch by Anton Khirnov wyskas gmail com Originally committed as revision 22057 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	36b54927fd	Dont allocate direct_table 8 times too large. Originally committed as revision 22056 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	013202d720	Simplify intra4x4_pred_mode_cache init. Originally committed as revision 22054 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	c2186cbddc	unroll tiny and trivial loop. Same speed but clearer. Originally committed as revision 22051 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
Stefano Sabatini	b6a4185367	10l: add prefix "TAG:" to the metadata tags key showed for each stream. This is consistent with the metadata displaying in show_format() and with the documentation. Originally committed as revision 22046 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	912dd63ecb	Cosmetics: replace "filename" to "arg" for the name of the argument of opt_input_file(). More consistent and more clear, as "filename" can be easily confused with the global "input_filename". Originally committed as revision 22045 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	c4a90caae2	aac: Keep decode_band_types() from eating all padding at the end of a buffer. Due to a shortcoming in the AAC specification, if an all zero buffer is fed to section data decoding it will never terminate. That means without a buffer exhaustion check decode_band_types() will consume all input buffer padding. Worse if a get_bits() implementation that returns zeros when padding is exhausted is used, the function will never terminate. The fixes that by added a buffer exhaustion check in the sectioning decoding loop. Originally committed as revision 22044 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	3314799368	Extend doxy for the src parameter of av_fifo_generic_write(). @patchby Tomas Härdin \|tomas dot hardin at codemill dot se\| Originally committed as revision 22043 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
