Stefano Sabatini	4c8fc6a2a4	lavfi/testsrc: use AVFILTER_DEFINE_CLASS for defining the filter classes Factorize.	13 years ago
Stefano Sabatini	33474eb1c6	lavfi/testsrc: extend logic in request_frame, support static image output	13 years ago
Stefano Sabatini	20e940e768	lavfi/testsrc: free the context in uninit Keeping stuff in the context can be useful for debugging purposes.	13 years ago
Nicolas George	f952b23ed4	vf_tile: fix output buffer ownership. There is no need to start_frame immediately on the output link since the rest is only done with the last frame of the tile. link->out_buf is now automatically dereferenced; since we give it away it must be cleared. Fix an assert failure; found by Clément Bœsch.	13 years ago
Stefano Sabatini	7ddf082f04	lavfi/testsrc: drop pointless parentheses	13 years ago
Stefano Sabatini	2702e38477	lavfi: remove unused defaults.c file	13 years ago
Diego Biurrun	d1505db067	x86: yadif: Mark mmxext optimizations as such The yadif mmx optimizations contain the pmaxsw and pmaxub mmxext instructions, causing sigills on CPUs that do not support mmxext.	13 years ago
Stefano Sabatini	52bd9cb4d2	lavfi/movie: force channel layout if not set by the decoder This ensures that the output buffers will have the channel layout set, which is required by filters. Also consistent with ffmpeg.c behavior.	13 years ago
Stefano Sabatini	b4c3359828	lavfi/asettb: do not create a new reference in filter_samples() There is no need to duplicate the input reference, since a filter should not pass along a reference which is later modified. If this happens the filter passing the reference should be fixed. Also improve consistency with start_frame() of settb, allowing a pending factorization.	13 years ago
Nicolas George	a85b4a5696	lavfi: use correct PTS for link age. When start_frame has returned, the buffer reference's PTS may have been modified by another filter.	13 years ago
Michael Niedermayer	3161958455	yadif: update frame rate Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	dfd8f2ff19	avfilter: fix minor typo Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	316f6df9cc	lavfi/avcodec: rename picref->samplesref variable in avfilter_get_audio_buffer_ref_from_frame() The new name is more meaningful in that context.	13 years ago
Stefano Sabatini	9cf9214d0a	lavfi/color: free internal context options in uninit() Keeping the set options in the context when the component is still used can be useful for debugging purposes.	13 years ago
Stefano Sabatini	a74dcb7dc0	lavfi/color: cache and reuse colored picture in context Avoid to fill the same picture again and again with the same content. Optimize computation, and provides an example for the use of the AV_PERM_REUSE permission flag.	13 years ago
Stefano Sabatini	47b6b7a2b9	lavfi/color: reindent after the previous commit	13 years ago
Stefano Sabatini	e5d617aa6d	lavfi/color: drop support for old deprecated syntax	13 years ago
Stefano Sabatini	ad2022ac83	lavfi/testsrc: add comment in options	13 years ago
Justin Ruggles	be51e589cd	af_asyncts: avoid overflow in out_size with large delta values	13 years ago
Justin Ruggles	70d71b5801	af_asyncts: add first_pts option This allows for padding/trimming at the start of stream. By default, no assumption is made about the first frame's expected pts, so no padding or trimming is done.	13 years ago
Loren Merritt	1ad715dbf3	vf_hqdn3d: support 9 and 10bit colordepth Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Loren Merritt	0f583e6cc5	vf_hqdn3d: reduce intermediate precision 11% faster on penryn, 7% on sandybridge, 5% on bulldozer Negligible change to output. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Loren Merritt	85e228c71d	vf_hqdn3d: simplify and optimize 14% faster on penryn, 2% on sandybridge, 9% on bulldozer Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Loren Merritt	fb44e7401f	factor identical ff_inplace_start_frame out of two filters Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Loren Merritt	60b9785530	vf_hqdn3d: cosmetics Change code style to match the rest of libav. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Nicolas George	efcfcf8793	avf_concat: fix silence duration. concat_in.pts starts at 0 for each segment, so the duration of the silence was too long, except at the first stitch.	13 years ago
Nicolas George	4ce87ecf2a	asrc_flite: do not crash on multiple instances. The voice register functions return the same voice structure upon multiple registration. It causes us two problems: If we delete a voice without deregistering it, it leaves a dangling pointer inside the library. If we delete or unregister a voice at uninit, it may still be in use by another instance of the filter. The second problem is solved by keeping an usage counter inside asrc_flite. This is not thread-safe, but neither is flite itself.	13 years ago
Anton Khirnov	b3fa478823	lavfi: bump minor to mark stabilizing the ABI.	13 years ago
Nicolas George	9a757cca34	avf_concat: fix min value for v option.	13 years ago
Stefano Sabatini	66a5201819	lavfi: add flite audio source	13 years ago
Stefano Sabatini	32390d6767	lavfi: move movie and amovie to a "multimedia sources" section Since the recent changes, movie and amovie are able to deal with more than one type of stream, so they should be categorized as "multimedia sources" rather than audio/video sources.	13 years ago
Justin Ruggles	743f07062a	lavfi: better channel layout negotiation Allow substitution of channel pairs in the input for nearby channel pairs in the output in order to get a closer match. Also weigh LFE channel mismatch differently to favor matching the same layout without LFE over one less channel with LFE.	13 years ago
Steven Robertson	b3841db133	vf_alphamerge: Fix reversed conditional Reviewed-by: Nicolas George	13 years ago
William Yu	d5d5e3dabe	lavfi/af_amerge: avfilter_copy_buffer_ref_props will overwrite output pts	13 years ago
Anton Khirnov	b5c8aa745e	vf_yadif: unset cur_buf on the input link. The buffer is stored internally, so this prevents it from being unreffed automatically. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Anton Khirnov	f431315a86	vf_overlay: ensure the overlay frame does not get leaked. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Michael Niedermayer	08fc1ad151	vf_overlay: prevent premature freeing of cur_buf Signed-off-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Stefano Sabatini	e564de26b3	lavfi/avfilter.h: add doxy for AVFilterLink.out_buf	13 years ago
Stefano Sabatini	b73be80d48	lavfi/avfilter.h: add doxy for AVFilterLink.cur_buf	13 years ago
Diego Biurrun	49c45a2624	avfilter: Fix printf format string conversion specifier libavfilter/avfilter.c:224:9: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 5 has type ‘int’ [-Wformat]	13 years ago
Nicolas George	ddcb99bb51	vf_deshake: set cur_buf to NULL. Fix a segfault.	13 years ago
Paul B Mahol	ebe846fa73	vf_colormatrix: add missing semicolon Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Nicolas George	a7ac05ce2f	src_movie: implement multiple outputs. The audio and video code paths were too different, most of the decoding has been rewritten.	13 years ago
Nicolas George	05776119c1	buffersrc: use avfilter_get_buffer_ref_from_frame.	13 years ago
Nicolas George	5c5f75b92b	lavfi: add avfilter_get_buffer_ref_from_frame.	13 years ago
Stefano Sabatini	7afd42d9f2	lavfi/showwaves: do not set on outlink->out_buf the sent video frame The video frame reference is passed along the filterchain, and is not possessed anymore by the filter. If out_buf is not set to NULL, it will be freed by ff_end_frame() causing a crash.	13 years ago
Michael Niedermayer	67a304985e	vf_overlay: fix missed return Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	612307978d	lavfi: change "transmedia" into "multimedia".	13 years ago
Nicolas George	be33da9a1d	lavfi: add concat filter.	13 years ago
Ronald S. Bultje	3124886554	lavfi: place x86 inline assembly under HAVE_INLINE_ASM. This allows compiling this code using compilers that do not understand gcc-style inline assembly.	13 years ago
