* 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/formats: Factor common function combinations outAndreas Rheinhardt2021-08-13
| | | | | | | | | | | Several combinations of functions happen quite often in query_format functions; e.g. ff_set_common_formats(ctx, ff_make_format_list(sample_fmts)) is very common. This commit therefore adds functions that are equivalent to commonly used function combinations in order to reduce code duplication.

* lavfi/xbr: undef PI if definedClément Bœsch2017-03-29
| | | | | | | | | | This conflict with the DJGPP libc math.h which includes a PI macro (to M_PI). We cannot make DJGPP POSIX only (using -D_POSIX_SOURCE) to avoid this kind of symbols conflicts due to the lack of both posix_memalign and memalign (DJGPP non standard function) in that POSIX mode. We currently rely on memalign for aligned heap allocation.
