- Drop add-gpl-option.patch: It no longer applies, but what is more
  important is that it does not make sense. Adding the gpl option
  only mattered when building the included ffmpeg sources gst-libav
  had when it still supported autotools. We can not change how the
  external ffmpeg we depend on is built, we take what we are given
  in this case. Our ffmpeg is built with GPL-3.0-or-later as
  license, hence change the license for this package to
  GPL-3.0-or-later in order to reflect that fact.
- Drop Supplements and Requires. No longer autoinstall this package
  as when gst-libav is not available, the hardwaresupported codecs
  in gst-bad finaly get to shine and strutt their wings.
  Upstream sets basicly all decoders from gst-libav to a higher
  preferance score, as they assume if you have gst-libav installed,
  you want to use it for almost everything.

- Update to version 1.18.6:
  + avcodecmap: Add support for GBRA_10LE/BE.

  - Fix size of linesize parameter
  - Take into account coded_height for pool
  + avdemux: fix build with FFmpeg 4.4

- Update add-gpl-option.patch: the proper language to be used is
  cpp, not c++; fixes build with meson 0.59.

- Update to version 1.18.4:
  + h264 encoder: append encoder exposure to aud
  + postproc: Fix a problem of propose_allocation when passthrough

  + avauddec: Drain decoder on decoding failure, fixes timestamps
    after decoding errors
