Paul B Mahol	16f1e832ba	lavfi/overlay: remove dupe initializer Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Stefano Sabatini	d2752ef061	lavfi/overlay: add process_command callback	12 years ago
Stefano Sabatini	006e20bd36	lavfi/overlay: add enable expression This expression is useful to enable/disable overlaying on the fly. Note that this can't be easily done relying on the filtergraph structure, since this implies caching issues or a null frame overlaying in the best case, which is better avoided for performance and convenience reasons.	12 years ago
Stefano Sabatini	cc3edd99a6	lavfi/overlay: add dynamic expression evaluation support Add support for dynamic x, y expressions evaluation. Also add support for an evaluation mode which allows to disable per-frame evaluation, so that there is no speedloss in case the expression does not depend on frame variables.	12 years ago
Anton Khirnov	9087eaf193	vf_overlay: switch to an AVOptions-based system.	12 years ago
Stefano Sabatini	39aad43465	lavfi/overlay: fix debug PTS output in try_filter_frame() The PTS of the input frames must be interpreted according to the input timebase, which is not the same as the output timebase.	12 years ago
Clément Bœsch	e62587bc5e	lavfi/overlay: use standard options parsing.	12 years ago
Clément Bœsch	96e4b00d62	lavfi: remove remaining forgotten min/rej perms.	12 years ago
Anton Khirnov	7e350379f8	lavfi: switch to AVFrame. Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it and use AVFrame instead.	12 years ago
Stefano Sabatini	8d9509377e	lavfi/overlay: improve log message warning in case of clipped overlay	12 years ago
Stefano Sabatini	f164228fd7	lavfi/overlay: add support for partial overlaying Partially rework the iteration logic, in order to limit iteration only for the clipped overlay region.	12 years ago
Michael Niedermayer	cfcab4c507	vf_overlay: silence warning: X may be used uninitialized in this function Also ensure that format is valid in query_formats Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Stefano Sabatini	22b06103f0	lavfi/overlay: add format option In particular, fix misbehavior in case main and overlay input formats mismatch (e.g. YUV420 and YUV444).	12 years ago
Stefano Sabatini	2db0056f96	lavfi/overlay: apply minor consistency fixes	12 years ago
Stefano Sabatini	3d77a27548	lavfi/overlay: implement shortest option Force termination when the overlay stream ends. Simplify scripting logic, for example when an infinite source is used to generate a background for a composite video.	12 years ago
Paul B Mahol	f2d200d460	lavfi/overlay: yuv444p & yuva444p support Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Nicolas George	7e5c5fa5fc	lavfi/vf_overlay: check that filter_frame does not return EAGAIN. EAGAIN is used internally in the code; it currently does not make sense as a return code from the next filter. Should fix CID966655.	12 years ago
Stefano Sabatini	bde1e8bf06	lavfi/overlay: make use of av_opt_set_from_string() Simplify.	12 years ago
Stefano Sabatini	5e402a5319	lavfi/overlay: switch to filter_frame API	12 years ago
Paul B Mahol	185d1f3bfc	lavfi: declare arrays that never change as static const Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Stefano Sabatini	54b0c04ae3	lavfi/overlay: clarify/fix comment, add a few empty lines to ease readability	12 years ago
Stefano Sabatini	3d1e2ada25	lavfi/overlay: remove duplicated definition of ff_null_get_video_buffer() Simplify.	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
Mark Himsley	13c6252536	lavfi/overlay: enable yuva420p as overlay background Same calculation as for RGBA etc to create unpremultiplied output. Useful for creating an intermediate "Mix/Effects bank", in vision mixer (switcher) terminology. Example command: ffmpeg -i input.mov -vf "[in]scale=iw:ih:interl=1,format=yuv420p[bg];movie=BBC_blocks_watermark.png,scale=iw:ih:interl=1,format=yuva420p[dog];movie=Kickabout_strap.mov,scale=iw:ih:interl=1,format=yuva420p[strap];[strap][dog]overlay=0:0[me1];[bg][me1]overlay=0:0,scale=0:0:interl=1[out]" -b:v 3M -an output.mov Fix trac ticket #549.

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
Anton Khirnov	59ee9f78b0	lavfi: do not use av_pix_fmt_descriptors directly.	12 years ago
Mans Rullgard	568c70e79e	lavfi: convert input/ouput list compound literals to named objects A number of compilers, for example those from TI and IBM, choke on these initialisers. The current style is also quite ugly. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago
Anton Khirnov	4673a5a761	vf_overlay: properly sync inputs. Right now it incorrectly assumes that the frames are sent in the proper order, which worked with old ffmpeg and avconv versions by accident.	12 years ago
Anton Khirnov	ab35ec29a4	vf_overlay: get rid of pointless messing with timebase. Output frames correspond 1:1 to input frames on the main input. So use the main input timebase for output.	12 years ago
Nicolas George	52820bc578	lavfi/overlay: fix return values. They were only roughly adapted when error return was added to the push functions.	13 years ago
Stefano Sabatini	42d621d131	lavfi: add priv class to filter definitions and flags to filter internal options This allows the iteration callbacks to discover the internal class and options, and show them when required.	13 years ago
Nicolas George	616c3f3ee2	vf_overlay: fix permissions.	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
Clément Bœsch	ad55244c96	lavfi/overlay: remove dead initialization.	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
Michael Niedermayer	67a304985e	vf_overlay: fix missed return Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	9c1d649ce5	overlay: clear cur_buf on main input link. A reference is kept in the queue and freed after use.	13 years ago
Anton Khirnov	1dc4205018	lavfi: check all avfilter_ref_buffer() calls for errors.	13 years ago
Anton Khirnov	02ac7311c8	lavfi: use avfilter_unref_bufferp() where appropriate.	13 years ago
Anton Khirnov	d4f89906e3	lavfi: add error handling to end_frame().	13 years ago
Anton Khirnov	e9b992d035	lavfi: add error handling to draw_slice().	13 years ago
Anton Khirnov	ebc8d97481	lavfi: add error handling to start_frame().	13 years ago
Ronald S. Bultje	3db407038e	lavfi: use const for AVFilterPad declarations in all filters.	13 years ago
Michael Niedermayer	f7e0c18549	vf_overlay: prevent premature freeing of cur_buf Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	0ecaa447f6	vf_overlay: use unref_bufferP() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Anton Khirnov	ad8b6326aa	vf_overlay: don't access a buffer reference that's been given away.	13 years ago
Anton Khirnov	1a49a169eb	lavfi: make filters less verbose.	13 years ago
