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 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)

- deprecate --hwdec-api and replace it with --opengl-hwdec-interop.
The new option accepts both --hwdec values, as well as named backends.
