* avfilter: add AVFILTER_FLAG_METADATA_ONLYAnton Khirnov2021-12-04
| | | | | | This flag allows distinguishing between filters that actually modify the data and those that only modify metadata or gather some stream information.

* 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.

* all: use FFDIFFSIGN to resolve possible undefined behavior in comparatorsGanesh Ajjanagadde2015-11-03
| | | | | | | | | | | | | | | | | | | FFDIFFSIGN was created explicitly for this purpose, since the common return a - b idiom is unsafe regarding overflow on signed integers. It optimizes to branchless code on common compilers. FFDIFFSIGN also has the subjective benefit of being easier to read due to lack of ternary operators. Tested with FATE. Things not covered by this are unsigned integers, for which overflows are well defined, and also places where overflow is clearly impossible, e.g an instance where the a - b was being done on 24 bit values.
