* avfilter/avfilter: Add FFFilter, hide internals of AVFilterAndreas Rheinhardt2025-01-121-12/+10
| | | | | | | | | | This patch is analogous to 20f972701806be20a77f808db332d9489343bb78: It hides the internal part of AVFilter by adding a new internal structure FFFilter (declared in filters.h) that has an AVFilter as its first member; the internal part of AVFilter is moved to this new structure.

* lavfi: drop internal.hAnton Khirnov2024-08-191-1/+0
| | | | | | All that remains in it are things that belong in avfilter_internal.h. Move them there and remove internal.h
* avfilter: Remove unnecessary formats.h inclusionsAndreas Rheinhardt2023-08-071-2/+0
| | | | | | | | | | | | | A filter needs formats.h iff it uses FILTER_QUERY_FUNC(); since lots of filters have been switched to use something else than FILTER_QUERY_FUNC, they don't need it any more, but removing this header has been forgotten. This commit does this; files with formats.h inclusion went down from 304 to 139 here (it were 449 before the preceding commit). While just at it, also improve the other headers a bit.

* avfilter: Deduplicate default video inputs/outputsAndreas Rheinhardt2023-08-071-8/+1
| | | | | | | | | | | | | | | | | Lots of video filters use a very simple input or output: An array with a single AVFilterPad whose name is "default" and whose type is AVMEDIA_TYPE_VIDEO; everything else is unset. Given that we never use pointer equality for inputs or outputs*, we can simply use a single AVFilterPad instead of dozens; this even saves .data.rel.ro (8312B here) as well as relocations. *: In fact, several filters (like the filters in vf_lut.c) already use the same outputs; furthermore, ff_filter_alloc() duplicates the input and output pads so that we do not even work with the pads directly.

* avfilter/avfilter: Add numbers of (in|out)pads directly to AVFilterAndreas Rheinhardt2021-08-201-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now, an AVFilter's lists of input and output AVFilterPads were terminated by a sentinel and the only way to get the length of these lists was by using avfilter_pad_count(). This has two drawbacks: first, sizeof(AVFilterPad) is not negligible (i.e. 64B on 64bit systems); second, getting the size involves a function call instead of just reading the data. This commit therefore changes this. The sentinels are removed and new private fields nb_inputs and nb_outputs are added to AVFilter that contain the number of elements of the respective AVFilterPad array. Given that AVFilter.(in|out)puts are the only arrays of zero-terminated AVFilterPads an API user has access to (AVFilterContext.(in|out)put_pads are not zero-terminated and they already have a size field) the argument to avfilter_pad_count() is always one of these lists, so it just has to find the filter the list belongs to and read said number. This is slower than before, but a replacement function that just reads the internal numbers that users are expected to switch to will be added soon; and furthermore, avfilter_pad_count() is probably never called in hot loops anyway. This saves about 49KiB from the binary; notice that these sentinels are not in .bss despite being zeroed: they are in .data.rel.ro due to the non-sentinels.

* lavfi: make filter_frame non-recursive.Nicolas George2016-12-181-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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.
* avfilter/formats: allow unknown channel layouts by defaultMarton Balint2016-12-101-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
