2021-10-05avfilter: Replace query_formats callback with union of list and callbackAndreas Rheinhardt
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.

2021-09-26avfilter/formats: Make ff_formats_pixdesc_filter return AVFilterFormats*Andreas Rheinhardt
Up until now, it has returned the AVFilterFormats list via an AVFilterFormats** parameter; the actual return value was an int that was always AVERROR(ENOMEM) on error. The AVFilterFormats** argument was a pure output parameter which was only documented by naming the parameter rfmts. Yet nevertheless all callers initialized the underlying AVFilterFormats* to NULL. This commit changes this to return a pointer to AVFilterFormats directly. This is more in line with the API in general, as it allows to avoid checks for intermediate values.

2021-08-20avfilter/avfilter: Add numbers of (in|out)pads directly to AVFilterAndreas Rheinhardt
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.

2015-10-14avfilter/all: propagate errors of functions from avfilter/formatsGanesh Ajjanagadde
Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM). This propagates the return values. All of these were found by using av_warn_unused_result, demonstrating its utility. Tested with FATE. I am least sure of the changes to avfilter/filtergraph, since I don't know what/how reduce_format is intended to behave and how it should react to errors. Fixes: CID 1325680, 1325679, 1325678.
