Michael Niedermayer	8f025f2f60	avfilter: align allocated images to 32 for AVX and IFF Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	c1ae524e2b	avfilter: fix AVFilterPad video only comment.	13 years ago

Mans Rullgard	cc276c85d1	Make channel layout masks unsigned It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Michael Niedermayer	6d16a96a95	vf_boxblur: fix memleak As the filter uses the default start frame, the cleanup done by the default end frame is needed. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	656911d84d	vsrc_mandelbrot: Fix vsrc_mandelbrot.c:358:85: warning: ‘epsilon’ may be used uninitialized in this function [-Wuninitialized] Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	248bb81ebc	avfilter: Error out from avfilter_merge_formats() when there are duplicates instead of trying to continue. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	4d874fc2b1	vf_mp: rewrite vf_mp filter warning message Warning text by: Clément Bœsch <ubitux@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	8cda755c2f	avfilter: dont write out of array for duplicate formats in avfilter_merge_formats() Note, this is a theoretical fix, iam not aware of a case where this function receives duplicates in its input. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	78317881f0	graphparser: Fix doxy on avfilter_graph_parse() return value. Found-by: ZacS123 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	2f0f9a87d0	Fix various if parenthesis misplacements.	13 years ago

Clément Bœsch	4da45aff28	cleanup: remove various double end ';' all over the code.	13 years ago
Michael Niedermayer	04bb26e3ee	mandelbrot: add dither to convergence & mincol colorings. This avoids banding artifacts. Note, low end TFTs still show some banding. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	4c52adad69	mandelbrot: Fix "warning: passing argument 2 of ‘draw_mandelbrot’ from incompatible pointer type" Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	2b1a4c5b34	amovie: avoid crash in amovie_request_frame() if no samplesref is available The crash occurrs when a frame is successfully decoded, but no decoded data is immediately available (typically happens with ogg/vorbis).	13 years ago
Michael Niedermayer	73af8ea356	mandelbrot: add math.h for log2() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	e8499ab171	mandelbrot: Add inner variable & enum for inner coloring schemes. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	3cbe9afba5	mandelbrot: only check bailout once every 2 iterations. Once we bailed out we calculate the exact iteration in which it would have happened if needed. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	41fd1b2d5a	mandelbrot: add SQR() macro Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Giorgio Vazzana	e555119c73	mandelbrot: correct and simplify the formula used in NORMALIZED_ITERATION_COUNT Use log(sqrt(mb->bailout)) instead of log(mb->bailout) because mb->bailout represent the bailout radius squared, and then simplify the two sqrt(). This is also slightly faster. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	88166fc579	mandelbrot: unroll the innermost loop once. This allows us to remove a if() and a variable assignment. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	1d06608732	mandelbrot: only check periodicity once for each period instead of twice. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	2fee131b9e	mandelbrot: use period detection depening on left pixel and not the previous calculated pixel, this is more accurate due to the last calculated often being farther away. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Giorgio Vazzana	be97e7b9c2	mandelbrot: remove unused variables Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
