* 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.

* avfilter/vf_mpdecimate: debug logging of threshold statsPeter Cordes2015-05-31
| | | | | | | | | | | It's often really helpful to know why a frame wasn't decimated (lo or hi), and how much you exceeded the threshold by, if you're trying to tweak the thresholds to get what you want. mpdecimate already prints a line per input frame with -v debug, this just makes it longer.

| | | | | | | | dsputil_init() is deprecated and not meant to be exported. ff_dsputil_init() is internal to libavcodec and thus can not be used. avpriv_dsputil_init() is the version shared between libraries. This commit fixes 3 unjustified libavfilter deprecated warnings.
* lavfi: rename decimate to mpdecimate.Clément Bœsch2013-04-14
The next commit will introduce a proper decimation filter to be used along with the field matching filter. To avoid confusion with this filter which has currently a very limited usage (and will not work properly with the fieldmatching filter), the new decimation filter will take the decimate name, and this filter is renamed to mpdecimate.
