* avfilter: Replace query_formats callback with union of list and callbackAndreas Rheinhardt2021-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Rheinhardt2021-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* avfilter/internal: Mark ff_filter_get_nb_threads() as av_pureAndreas Rheinhardt2021-07-18
| | | | | | | | | | | It does not modify anything; it only returns a value, so it fulfills the requirements for av_pure. The deeper rationale behind this change is that this function is called quite often inside arguments to FFMIN which may lead to two calls to it; declaring this function as av_pure allows the compiler to optimize the second call away.

| * lavfi: Always propagate hw_frames_ctx through linksMark Thompson2016-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also adds a new flag to mark filters which are aware of hwframes and will perform this task themselves, and marks all appropriate filters with this flag. This is required to allow software-mapped hardware frames to work, because we need to have the frames context available for any later mapping operation in the filter graph. The output from the filter graph should only propagate further to an encoder if the hardware format actually matches the visible format (mapped frames are valid here and have an hw_frames_ctx, but this should not be given to the encoder as its hardware context).
