* lavfi/setpts: unset frame durationsAnton Khirnov2024-03-29
| | | | | | | Actual frame durations are, in general, not computable without buffering a frame. FIxes #10886
* lavf/vf_setpts: unset output framerateAnton Khirnov2024-03-29
| | | | | | This filter produces VFR output in general. Avoids dropping frames in the setpts test.

* avfilter: Deduplicate default video inputs/outputsAndreas Rheinhardt2023-08-07
| | | | | | | | | | | | | | | | | Lots of video filters use a very simple input or output: An array with a single AVFilterPad whose name is "default" and whose type is AVMEDIA_TYPE_VIDEO; everything else is unset. Given that we never use pointer equality for inputs or outputs*, we can simply use a single AVFilterPad instead of dozens; this even saves .data.rel.ro (8312B here) as well as relocations. *: In fact, several filters (like the filters in vf_lut.c) already use the same outputs; furthermore, ff_filter_alloc() duplicates the input and output pads so that we do not even work with the pads directly.

* lavu/frame: deprecate AVFrame.pkt_{pos,size}Anton Khirnov2023-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | These fields are supposed to store information about the packet the frame was decoded from, specifically the byte offset it was stored at and its size. However, - the fields are highly ad-hoc - there is no strong reason why specifically those (and not any other) packet properties should have a dedicated field in AVFrame; unlike e.g. the timestamps, there is no fundamental link between coded packet offset/size and decoded frames - they only make sense for frames produced by decoding demuxed packets, and even then it is not always the case that the encoded data was stored in the file as a contiguous sequence of bytes (in order for pos to be well-defined) - pkt_pos was added without much explanation, apparently to allow passthrough of this information through lavfi in order to handle byte seeking in ffplay. That is now implemented using arbitrary user data passthrough in AVFrame.opaque_ref. - several filters use pkt_pos as a variable available to user-supplied expressions, but there seems to be no established motivation for using them. - pkt_size was added for use in ffprobe, but that too is now handled without using this field. Additonally, the values of this field produced by libavcodec are flawed, as described in the previous ffprobe conversion commit. In summary - these fields are ill-defined and insufficiently motivated, so deprecate them.
* configure: Use a separate config_components.h header for $ALL_COMPONENTSMartin Storsjö2022-03-16
| | | | | | | | This avoids unnecessary rebuilds of most source files if only the list of enabled components has changed, but not the other properties of the build, set in config.h. Signed-off-by: Martin Storsjö <martin@martin.st>
* 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.
