Anton Khirnov	b9c928a486	avfilter: add AVFILTER_FLAG_METADATA_ONLY This flag allows distinguishing between filters that actually modify the data and those that only modify metadata or gather some stream information.	3 years ago
Andreas Rheinhardt	8be701d9f7	avfilter/avfilter: Add numbers of (in\|out)pads directly to AVFilter 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.

Andreas Rheinhardt	d4e29d9c5e	avfilter/fifo: Remove unused functions and headers The functions were forgotten in 03c8fe49ea3f2a2444607e541dff15a1ccd7f0c2; removing them also means that the avassert.h and samplefmt.h headers are no longer used any more, so they have been removed, too. Moreover, video.h is unused since `b077d8d908` and channel_layout.h is since `fdd9663781`. Both headers have therefore been removed, too.
