* 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.

| | | | | | | | The code for inserting inpads can't be reached by ff_vsrc_openclsrc (unsurprising given that it is a source filter), so it didn't get the flag. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavfi/opencl: Avoid deprecation warnings when built with post-1.2 headersMark Thompson2018-03-22
| | | | | | | | | | The intended target is OpenCL 1.2, so disable warnings for APIs deprecated after that. This primarily applies to clCreateCommandQueue(), we can't use the replacement clCreateCommandQueueWithProperties() because it was introduced in OpenCL 2.0. Also remove some unnecessary includes from overlay and program filters so that the define is available at the right moment.
* lavfi/opencl: Derive global work size from plane image sizesMark Thompson2018-03-22
| | | | | | | Add a new function to find the global work size given the output image and the required block alignment, then use it in the overlay, program and unsharp filters. Fixes the overlay and unsharp filters applying the kernel to locations outside the frame when subsampled planes are present.
