Stefano Sabatini	0407a79e41	lavfi/blackframe: add support for named options	12 years ago
Hendrik Leppkes	d8dccf69ff	lavfi: let gcc realign the stack on public graph driving functions The functions which actually drive the filter graph by pushing frames through it need to ensure an aligned stack for SIMD functions. This fixes a crash in YADIF filter when using a mingw build in a MSVC application. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Clément Bœsch	8d84e90c9b	lavfi/delogo: 10l forgotten trailing NULL in shorthand. Regression since `de3e0ab3`.	12 years ago
James Darnley	c9a51c29fc	yadif: remove an 'm' from the LOAD macro definition Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
James Darnley	1d3b14cac2	yadif: remove repeated check on width The filter already checks that width (and height) are greater than 3. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
James Darnley	7976d92dac	yadif: cosmetic indentation from previous commits Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
James Darnley	0a5814c9ba	yadif: x86 assembly for 9 to 14-bit samples These smaller samples do not need to be unpacked to double words allowing the code to process more pixels every iteration (still 2 in MMX but 6 in SSE2). It also avoids emulating the missing double word instructions on older instruction sets. Like with the previous code for 16-bit samples this has been tested on an Athlon64 and a Core2Quad. Athlon64: 1809275 decicycles in C, 32718 runs, 50 skips 911675 decicycles in mmx, 32727 runs, 41 skips, 2.0x faster 495284 decicycles in sse2, 32747 runs, 21 skips, 3.7x faster Core2Quad: 921363 decicycles in C, 32756 runs, 12 skips 486537 decicycles in mmx, 32764 runs, 4 skips, 1.9x faster 293296 decicycles in sse2, 32759 runs, 9 skips, 3.1x faster 284910 decicycles in ssse3, 32759 runs, 9 skips, 3.2x faster Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
James Darnley	17e7b49501	yadif: x86 assembly for 16-bit samples This is a fairly dumb copy of the assembly for 8-bit samples but it works and produces identical output to the C version. The options have been tested on an Athlon64 and a Core2Quad. Athlon64: 1810385 decicycles in C, 32726 runs, 42 skips 1080744 decicycles in mmx, 32744 runs, 24 skips, 1.7x faster 818315 decicycles in sse2, 32735 runs, 33 skips, 2.2x faster Core2Quad: 924025 decicycles in C, 32750 runs, 18 skips 623995 decicycles in mmx, 32767 runs, 1 skips, 1.5x faster 406223 decicycles in sse2, 32764 runs, 4 skips, 2.3x faster 387842 decicycles in ssse3, 32767 runs, 1 skips, 2.4x faster 307726 decicycles in sse4, 32763 runs, 5 skips, 3.0x faster Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Hendrik Leppkes	a77f453703	lavfi/avcodec: deprecate remainders of the avcodec glue code Since lavfi works natively with AVFrame now, these functions are no longer necessary and can be removed in a future bump. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Clément Bœsch	3b2b636a2a	lavfi: add perms and aperms filters.	12 years ago
Anton Khirnov	4750b05d67	af_join: do not leak input frames.	12 years ago
Anton Khirnov	c2b9bd97f5	asrc_anullsrc: return EOF, not -1	12 years ago
Anton Khirnov	f4281f4571	asrc_anullsrc: do not set samplerate and channel layout explicitly They are auto-negotiated.	12 years ago
Anton Khirnov	e4a7b2177d	vf_showinfo: remove its useless init function Filter private data is memset to 0 so there is no point in explicitly initing anything to 0.	12 years ago
Anton Khirnov	dd74e3ef33	avfiltergraph: use sizeof(var) instead of sizeof(type)	12 years ago
Anton Khirnov	42c7c61ab2	avfiltergraph: replace AVFilterGraph.filter_count with nb_filters This is more consistent with the naming in the rest of Libav.	12 years ago
Anton Khirnov	556aab8f11	lavfi: use designated initializers in avfilter_class	12 years ago
James Darnley	3d751b1ef6	yadif: correct strides in filter_edges_16bit The C code treats the data as arrays of uint16_t so strides must not be in bytes but in pixels. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	cd5f50a255	avfilter: avoid direct access to AVFrame.channels Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Clément Bœsch	9ace0dbe41	lavfi/ebur128: use same ref for inputs and outputs. Fixes Ticket2342.	12 years ago
Clément Bœsch	fe898a037d	Revert "lavfi/ebur128: fix format negociation for output." This reverts commit `9efcfbed9d`. All the shame on me; this commit is actually causing more problems (broken outputs but also crashes) than it was solving.	12 years ago
Clément Bœsch	9efcfbed9d	lavfi/ebur128: fix format negociation for output. Before this change, the audio input and output formats are set independently, so the lavfi negociation could pick different settings for the input and output. This is particularly true for the channel layout settings, where multiple choices were available. Fixes Ticket2342.	12 years ago
Clément Bœsch	a95a38793c	lavfi/thumbnail: support flushing. This makes possible the raise of one picture if the input has less than the number of frames to analyze. Fixes Ticket1992.	12 years ago

James Darnley	0735b50880	yadif: restore speed of the C filtering code Always use the special filter for the first and last 3 columns (only). Changes made in `64ed397` slowed the filter to just under 3/4 of what it was. This commit restores the speed while maintaining identical output. For reference, on my Athlon64: 1733222 decicycles in old 2358563 decicycles in new 1727558 decicycles in this Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
