* doc/ffmpeg: Extend documentation for sws_flags optionTobias Rapp2023-05-171-1/+6
| | | | | | Clarify that -sws_flags are only applied to simple filtergraphs as a default, not complex filtergraphs. Add a reference to the scaler options.
* lavc: deprecate AVCodecContext.ticks_per_frameAnton Khirnov2023-05-152-1/+5
| | | | | | | | For encoding, this field is entirely redundant with AVCodecContext.framerate. For decoding, this field is entirely redundant with AV_CODEC_PROP_FIELDS.
* lavc/codec_desc: add a property for codecs that support field codingAnton Khirnov2023-05-151-0/+3
| | | | | | | Multiple places currently use AVCodecContext.ticks_per_frame > 1 to identify such codecs, which * requires a codec context * requires it to be open
* lavc: deprecate AV_CODEC_CAP_SUBFRAMESAnton Khirnov2023-05-151-0/+3
| | | | There is nothing meaningful the caller can do with it.

* lavfi/vf_libplacebo: add frame_mixer optionNiklas Haas2023-05-141-0/+31
| | | | | Fairly straightforward. We just need to modify the scaler handling code slightly to support looking at a different list of filter presets.
* lavfi/vf_libplacebo: allow fps conversionNiklas Haas2023-05-141-0/+7
| | | | | | | | | | | This exposes libplacebo's frame mixing functionality to vf_libplacebo, by allowing users to specify a desired target fps to output at. Incoming frames will be smoothly resampled (in a manner determined by the `frame_mixer` option, to be added in the next commit). To generate a consistently timed output stream, we directly use the desired framerate as the timebase, and simply output frames in sequential order (tracked by the number of frames output so far).

| | | | | Percent sign is not a special character in popular shells, so the quoting isn't necessary.
* avfilter/vf_ccrepack: Add new filter to repack CEA-708 side dataDevin Heitmueller2023-05-111-0/+10
| | | | | | | | | | | | | THis filter can correct certain issues seen from upstream sources where the cc_count is not properly set or the CEA-608 tuples are not at the start of the payload as expected. Make use of the ccfifo to extract and immediately repack the CEA-708 side data, thereby removing any extra padding and ensuring the 608 tuples are at the front of the payload.

* doc/filters/crop: drop unmatched quote in exampleAndriy Utkin2023-05-111-1/+1
| | | | | | | Commit 55b81528a991 ("doc/filters: itemize crop examples") dropped the quotation marks from these examples, but this one remained. Quotes are actually needed to put the example into a command line or a program, but removing it here makes the example consistent with the document.

* avfilter/vf_libplacebo: add flexible crop exprsNiklas Haas2023-05-031-5/+50
| | | | | | | | | | | | | | | | | | | | Motivated by a desire to use vf_libplacebo as a GPU-accelerated cropping/padding/zooming filter. This commit adds support for setting the `input/target.crop` fields as dynamic expressions. Re-use the same generic variables available to other scale and crop type filters, and also add some more that we can afford as a result of being able to set these properties dynamically. It's worth pointing out that `out_t/ot` is currently redundant with `in_t/t` since it will always contain the same PTS values, but I plan on changing this in the near future. I decided to also expose `crop_w/crop_h` and `pos_w/pos_h` as variables in the expression parser itself, since this enables the fairly common use case of determining dimensions first and then placing the image appropriately, such as is done in the default behavior (which centers the cropped/placed region by default).
* avfilter/vf_libplacebo: add fillcolor optionNiklas Haas2023-05-031-0/+6
| | | | | | In some circumstances, libplacebo will clear the background as a result of cropping/padding. Currently, this uses the hard-coded default fill color of black. This option makes this behavior configurable.
* fftools/ffmpeg: deprecate -adrift_thresholdAnton Khirnov2023-05-021-6/+0

* doc/filters/libplacebo: add vaapi interop exampleNiklas Haas2023-04-261-0/+6
| | | | | | Some testing revealed this to be a very efficient and reliable method of ingesting GPU frames into libplacebo, so it's a good idea to give as an example.
* doc/filters/libplacebo: remove outdated exampleNiklas Haas2023-04-261-10/+0
| | | | | | | This example being first is now misleading because round-tripping through hwdownload/hwupload is neither required nor recommended. Also, the comment about avoiding format conversion is unnecessary because `libplacebo` will now inherit the input frame format by default.

* fftools/ffmpeg: disable and deprecate -qphistAnton Khirnov2023-04-131-2/+0
| | | | | | | | | | | | | | | | | | | | | | This option adds a long string of numbers to the progress line, where i-th number contains the base-2 logarithm of the number of times a frame with this QP value was seen by print_report(). There are multiple problems with this feature: * despite this existing since 2005, web search shows no indication that it was ever useful for any meaningful purpose; * the format of what is printed is entirely undocumented, one has to find it out from the source code; * QP values above 31 are silently ignored; * it only works with one video stream; * as it relies on global state, it is in conflict with ongoing architectural changes. It then seems that the nontrivial cost of maintaining this option is not worth its negligible (or possibly negative - since it pollutes the already large option space) value. Users who really need similar functionality can also implement it themselves using -vstats.
