* 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/psnr: rename pow2 to pow_2Clément Bœsch2017-03-29
| | | | | | | | | | | This conflict with the DJGPP libc which includes a pow2 function¹ 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. [1]: http://www.delorie.com/djgpp/doc/libc-2.02/libc_536.html

* avfilter: Add new format for PSNR stats logLucas Cooper2016-07-29
| | | | | | | | | | | | Add an AVOption stats_version with a new header for V2 stats, which specifies the stats log version and lists the fields that will be present in the log (to ease parsing). The primary motivation is to facilitate the addition of optional fields to the log without breaking backwards compatibility, while making the logs easier to parse.
