* avfilter/avfilter: Add FFFilter, hide internals of AVFilterAndreas Rheinhardt2025-01-121-10/+8
| | | | | | | | | | 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.

* avfilter: fix YUV colorspace negotiation for YUVJNiklas Haas2024-09-121-5/+10
| | | | | | | | | | | | | | | Ironically, despite being introduced to make YUVJ unnecessary, the new YUV negotiation logic failed to actually negotiate YUVJ formats themselves correctly, leading to errors when passing YUVJ frames into a filter graph. (They were effectively treated like RGB or Grayscale formats, rather than as forced-full-range YUV, and hence did not have their colorspace matrix correctly negotiated) Fix this by splitting off the YUVJ check from ff_fmt_is_regular_yuv(). Obviously, we can trivially undo this change again once YUVJ is actually deleted from the codebase. Fixes: #11179

* avfilter/buffersrc: fix overriding unknown channel layouts with negotiated oneMarton Balint2024-03-301-1/+1
| | | | | | | | | | | | | | | | | | Fixes ffplay playback of unknown layouts, when SDL directly supports the audio format, such as: ffplay -f lavfi anullsrc=cl=2C,aformat=s16 Without the patch, "Channel layout change is not supported" errors are generated because buffersrc (unknown 2 channel) and buffersink (stereo) negotiated a stereo layout, but the stereo layout was never stored in the BufferSourceContext. This fixes a regression of 7251f909721a570726775acf61b2b9c28a950c76, but this is more of a regression of the avfilter channel layout conversion (1f96db959c1235bb7079d354e09914a0a2608f62).

| | | | | | | | | | | | | | | | | | | | | | | | Makes it robust against adding fields before it, which will be useful in following commits. Majority of the patch generated by the following Coccinelle script: @@ typedef AVOption; identifier arr_name; initializer list il; initializer list[8] il1; expression tail; @@ AVOption arr_name[] = { il, { il1, - tail + .unit = tail }, ... }; with some manual changes, as the script: * has trouble with options defined inside macros * sometimes does not handle options under an #else branch * sometimes swallows whitespace
* avfilter/buffersrc: allow promoting color range to MPEGNiklas Haas2024-02-131-2/+8
| | | | | | | | | Otherwise, passing an UNSPECIFIED frame to am MPEG-only filter graph would trigger insertion of an unnecessary vf_scale filter, which would perform a memcpy to convert between the two. This is safe to do because unspecified YUV frames are already universally assumed to be MPEG range, in particular by swscale.
* avfilter/buffersrc: promote unspecified color metadataNiklas Haas2024-02-131-0/+5
| | | | | | | | | | | | Currently, this only affects untagged RGB/XYZ/Gray, which get forced to their corresponding metadata before entering the filter graph. The main justification for this change, however, is the planned ability to add automatic promotion of unspecified yuv to mpeg range yuv. Notably, this change will never allow accidentally cross-promoting unspecified to jpeg or to a specific YUV matrix, since that is still bound by the constraints of YUV range negotiation as set up by query_formats.
* avfilter/buffersrc: limit link variance logs below debug loglevelGyan Doshi2024-02-011-13/+27
| | | | | | | | | The video param change check will print loglines below debug level for each frame which is different from the inlink parameters. This can spam the console. It is now printed at warning level once for each param change else it is kept at debug level. Partially addresses #10823
* avfilter/buffersrc: add color_space/range parametersNiklas Haas2023-12-311-8/+67
| | | | | | | To allow adding proper negotiation, in particular, to fftools. These values will simply be negotiated downstream for YUV formats, and ignored otherwise.

* avfilter: Replace query_formats callback with union of list and callbackAndreas Rheinhardt2021-10-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If one looks at the many query_formats callbacks in existence, one will immediately recognize that there is one type of default callback for video and a slightly different default callback for audio: It is "return ff_set_common_formats_from_list(ctx, pix_fmts);" for video with a filter-specific pix_fmts list. For audio, it is the same with a filter-specific sample_fmts list together with ff_set_common_all_samplerates() and ff_set_common_all_channel_counts(). This commit allows to remove the boilerplate query_formats callbacks by replacing said callback with a union consisting the old callback and pointers for pixel and sample format arrays. For the not uncommon case in which these lists only contain a single entry (besides the sentinel) enum AVPixelFormat and enum AVSampleFormat fields are also added to the union to store them directly in the AVFilter, thereby avoiding a relocation. The state of said union will be contained in a new, dedicated AVFilter field (the nb_inputs and nb_outputs fields have been shrunk to uint8_t in order to create a hole for this new field; this is no problem, as the maximum of all the nb_inputs is four; for nb_outputs it is only two). The state's default value coincides with the earlier default of query_formats being unset, namely that the filter accepts all formats (and also sample rates and channel counts/layouts for audio) provided that these properties agree coincide for all inputs and outputs. By using different union members for audio and video filters the type-unsafety of using the same functions for audio and video lists will furthermore be more confined to formats.c than before. When the new fields are used, they will also avoid allocations: Currently something nearly equivalent to ff_default_query_formats() is called after every successful call to a query_formats callback; yet in the common case that the newly allocated AVFilterFormats are not used at all (namely if there are no free links) these newly allocated AVFilterFormats are freed again without ever being used. Filters no longer using the callback will not exhibit this any more.

* 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.
