af_drc: remove
Remove low quality drc filter. Anyone whishing to have dynamic range compression should use the much more powerful acompressor ffmpeg filter: mpv --af=lavfi=[acompressor] INPUT Or with parameters: mpv --af=lavfi=[acompressor=threshold=-25dB:ratio=3:makeup=8dB] INPUT Refer to https://ffmpeg.org/ffmpeg-filters.html#acompressor for a full list of supported parameters.

- remove ppm, pgm, pgmyuv, tga choices from the --screenshot-format and
--vo-image-format options
- the "jpeg" choice in the option above now leads to a ".jpg" file extension
+ - --af=drc is gone (you can use e.g. lavfi/acompressor instead)
--- mpv 0.24.0 ---
- deprecate --hwdec-api and replace it with --opengl-hwdec-interop.
The new option accepts both --hwdec values, as well as named backends.

the mixing matrix at runtime, without reinitializing the entire filter
chain.
-``drc[=method:target]``
- Applies dynamic range compression. This maximizes the volume by compressing
- the audio signal's dynamic range. (Formerly called ``volnorm``.)
-
- ``<method>``
- Sets the used method.
-
- 1
- Use a single sample to smooth the variations via the standard
- weighted mean over past samples (default).
- 2
- Use several samples to smooth the variations via the standard
- weighted mean over past samples.
-
- ``<target>``
- Sets the target amplitude as a fraction of the maximum for the sample
- type (default: 0.25).
-
- .. note::
-
- This filter can cause distortion with audio signals that have a very
- large dynamic range.
-
``scaletempo[=option1:option2:...]``
Scales audio tempo without altering pitch, optionally synced to playback
speed (default).
