Andreas Rheinhardt	1aa640c7d7	avfilter/internal: Combine get_(audio\|video)_buffer into union These fields are mutually exclusive, so putting them in a union is possible and makes AVFilterPad smaller.

Andreas Rheinhardt	6e66e2c321	avfilter/internal: Don't include framepool.h, thread.h They are not used by the header at all and only used by very few files; so include the headers in their users instead of in internal.h.

Paul B Mahol	4754d70a23	avfilter/video: pick sar from link It should not be needed for each filter that sets sample aspect ratio to set it explicitly also for each and every frame, instead that is automatically done in get_buffer call. Signed-off-by: Paul B Mahol <onemda@gmail.com>	7 years ago
Matthieu Bouron	b1f68f00b1	lavfi/framepool: rename FFVideoFramePool to FFFramePool	8 years ago

Paul B Mahol	b8b398027c	avfilter/video: remove commented out cruft Signed-off-by: Paul B Mahol <onemda@gmail.com>	11 years ago
Anton Khirnov	7e350379f8	lavfi: switch to AVFrame. Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it and use AVFrame instead.	12 years ago
Nicolas George	82541d8330	lavfi: merge all filtering code into ff_filter_frame.	12 years ago
Nicolas George	a978c04e22	lavfi/video: ensure that filter_frame is called. This is a temporary workaround until all filters have been upgraded to filter_frame and the framework can forget completely about start_frame/draw_slice/end_frame.	12 years ago
Michael Niedermayer	c0c0b19644	lavfi: remove some draw_slice related code that has become unneeded Reviewed-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	015c2b4066	libavfilter: default to filter_frame when neither it nor start/slice/end is set. this is needed for vf_null and a few others. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	3ed483cdfa	libavfilter: Support using filter_frame for video With this we can mix filters using filter_frame OR start/draw_slice/end Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	565e4993c6	lavfi: merge start_frame/draw_slice/end_frame Any alleged performance benefits gained from the split are purely mythological and do not justify added code complexity.	12 years ago
Hendrik Leppkes	79393a8363	Replace usage of the deprecated av_pix_fmt_descriptors array with av_pix_fmt_desc_get Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	5d2b885074	lavfi: limit matching w/h/fmt asserts to non scale filters This fixes a regression with the scale filters input changing. In the long run filters should get a flag to indicate support of this and then this flag be used here. But the regression should not be left standing until thats done. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	59ee9f78b0	lavfi: do not use av_pix_fmt_descriptors directly.	12 years ago

Nicolas George	8ad54a44eb	lavfi: check that buffer and link properties match.	12 years ago
Stefano Sabatini	a4cb0af945	lavfi: drop deprecated and pointless avfilter_default_end_frame() function Fix warning when compiling boxblur. While this is technically a major API break, practically there will be no one using that function since the filtering API is mostly private, so that function alone is not usable.	12 years ago
Michael Niedermayer	c9a0f9bf3c	libavfilter: pass QP table through the filter chain Any volunteers to port the pp and spp filters from libmpcodec? Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nicolas George	beeba9161a	lavfi: add a closed field to AVFilerLink. It will help forward errors and maintain consistency.	13 years ago
Nicolas George	cc8104b908	lavfi: fix erroneous use of AV_PERM_PRESERVE in ff_inplace_start_frame. ff_inplace_start_frame looks useless anyway.	13 years ago
Nicolas George	046eb21c72	lavfi: grant all permissions on mallocated video buffers. The permissions not requested by the filter that created the buffer may be useful for a later filter and avoid a copy.	13 years ago
Martin Storsjö	70766c2182	Add some more missing includes after removing the implicit common.h Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Nicolas George	271ddb116c	lavfi: use min_perms and rej_perms for out pads. There are several reasons for doing that: 1. It documents the code for the reader and helps find inconsistencies and bugs. 2. For rej_perms, it guarantees the change will be done even if the output reference can be created by several code paths. 3. It can be used to predict cases where a copy will, or will not happen and optimize buffer allocation (for example not request a rare direct-rendering buffer from a device sink if it will be copied anyway). Note that a filter is still allowed to manage the permissions on its own without using these fields.	13 years ago
Nicolas George	8ef740ce01	lavfi: use a new field for automatic buffer copy. The code currently use cur_buf as the target of the copy, but cur_buf can be cleared by the filter if it has given the reference away or stored it elsewhere as soon as start_frame. The code still relies on the fact that the reference is not destroyed until end_frame. All filters currently follow that condition. An av_assert1() is added to check it; it should at least cause very visible errors in valgrind.	13 years ago
Stefano Sabatini	65520f5933	lavfi/video: remove duplicated function ff_null_start_frame_keep_ref() Semantic for the function ff_null_start_frame() was changed in `07bad27810`, and it has now the same behavior of ff_null_start_frame_keep_ref(), thus it makes no sense to keep both of them.	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
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

Anton Khirnov	4c9080a7ef	lavfi: unref AVFilterLink.out_buf in ff_end_frame(). This reduces code duplication and prevents stale pointers from remaining on the link.	13 years ago
Anton Khirnov	07bad27810	lavfi: unref AVFilterLink.cur_buf in ff_end_frame(). This reduces code duplication and prevents stale pointers from remaining on the link.	13 years ago

Paul B Mahol	c9e183b490	lavfi: update some deprecated functions Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago
Stefano Sabatini	635a25954e	lavfi/video: set output frame w/h properties in default_start_frame() Use the same values of the video output link. Avoid the need to override the default_start_frame() with an ad-hoc start_frame() callback. In particular, fix the super2xsai filter which was setting the input w/h values in the output.	13 years ago
Anton Khirnov	9baeff9506	lavfi: replace AVFilterContext.input/output_count with nb_inputs/outputs This is more consistent with naming in the rest of Libav.	13 years ago
