Paul B Mahol	5e706a2afb	avfilter/split: check ff_insert_outpad() for failure Signed-off-by: Paul B Mahol <onemda@gmail.com>	7 years ago
Nicolas George	02aa0701ae	lavfi: make filter_frame non-recursive. A lot of changes happen at the same time: - Add a framequeue fifo to AVFilterLink. - split AVFilterLink.status into status_in and status_out: requires changes to the few filters and programs that use it directly (f_interleave, split, filtfmts). - Add a field ready to AVFilterContext, marking when the filter is ready and its activation priority. - Add flags to mark blocked links. - Change ff_filter_frame() to enqueue the frame. - Change all filtering functions to update the ready field and the blocked flags. - Update ff_filter_graph_run_once() to use the ready field. - buffersrc: always push the frame immediately.	8 years ago
Marton Balint	7ceb9e6b11	avfilter/formats: allow unknown channel layouts by default Since the default in the libav fork is to only allow known layouts, making unknown layouts allowed by default here can be a security risk for filters directly merged from libav. However, usually it is simple to detect such cases, use of av_get_channel_layout_nb_channels is a good indicator, so I suggest we change this regardless. See http://ffmpeg.org/pipermail/ffmpeg-devel/2016-November/203204.html. This patch indirectly adds unknown channel layout support for filters where query_formats is not specified: abench afifo ainterleave anullsink apad aperms arealtime aselect asendcmd asetnsamples asetpts asettb ashowinfo azmq It introduces a query_formats callback for the asyncts filter, which only supports known channel layouts since it is using libavresample. And it removes .query_formats callback from filters where it was only there to support unknown layouts, as this is now the default: aloop ametadata anull asidedata asplit atrim Acked-by: Nicolas George <george@nsup.org> Signed-off-by: Marton Balint <cus@passwd.hu>	8 years ago
Michael Niedermayer	7b7c338e9a	avfilter: Add AV_OPT_FLAG_FILTERING_PARAM to where it was missing Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Paul B Mahol	b1fe794033	avfilter/split: support any channel count for asplit filter Signed-off-by: Paul B Mahol <onemda@gmail.com>	9 years ago
Nicolas George	108b4de552	lavfi: replace link.closed by link.status. The status field can carry any error code instead of just EOF. Also only update it through a wrapper function and provide a timestamp. Update the few filters that used it directly.	9 years ago

Anton Khirnov	7cdd737ba8	lavfi: mark filters with dynamic number of inputs or outputs with special flags This will be useful in avtools in the following commits. Any other caller might also want to know this information.	12 years ago

Michael Niedermayer	cd7febd33f	lavfi: replace filter_samples by filter_frame Based on patch by Anton Khirnov 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
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>	12 years ago
Mans Rullgard	1fce361d70	lavfi: replace empty input/output lists with null pointers Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Ronald S. Bultje	3db407038e	lavfi: use const for AVFilterPad declarations in all filters.	12 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	cd99146253	lavfi: add error handling to filter_samples().	13 years ago
Anton Khirnov	083d0f6be8	asplit: don't leak the input buffer.	13 years ago
Anton Khirnov	a5e8c41c28	lavfi: remove 'opaque' parameter from AVFilter.init() It is not used in any filters currently and is inherently evil. If passing binary data to filters is required in the future, it should be done with some AVOptions-based system.	13 years ago
Stefano Sabatini	93bbe53c44	lavfi/asplit: fix memleak The input samples buffer must be unreferenced after it is propagated to the output links.	13 years ago
Stefano Sabatini	e20530add7	lavfi/split: give a more accurate description to split The filter now supports a configurable number of outputs.	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
Anton Khirnov	803391f719	lavfi: remove request/poll and drawing functions from public API on next bump They are only useful inside filters and we don't allow user filters for now.	13 years ago
Anton Khirnov	fa417fcd27	lavfi: make avfilter_insert_pad and pals private on next bump. They are only useful inside filters and we don't allow user filters for now.	13 years ago
Anton Khirnov	c04c533f62	lavfi: remove avfilter_null_* from public API on next bump. Those functions are only useful inside filters. It is better to not support user filters until the API is more stable.	13 years ago
Justin Ruggles	afeb3590fc	lavfi: add an audio split filter Based on current version of the asplit filter in FFmpeg written by Stefano Sabatini and others.	13 years ago
Justin Ruggles	cc30080b3f	lavfi: rename vf_split.c to split.c This is in preparation for adding an audio split filter.	13 years ago
Stefano Sabatini	0e82d317eb	lavfi: rename vf_split.c -> f_split.c The file now contains both an audio and a video split filter.	13 years ago

Anton Khirnov	fd18ee0ff6	vf_split: support user-specifiable number of outputs.	13 years ago
Reimar Döffinger	5af7daabc4	Mark AVFilterPad[] compound literals as const. GCC 4.6.2 at least still seems to fail to put them in .rodata though, see also http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37303 Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Bobby Bingham	615baa13e4	lavfi: add split filter from soc. Some fixes by Stefano. For detailed authorship see SOC repo Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
