Hi,

Your package FTBFS with version 4.0 of FFmpeg. In FFmpeg 4.0, there are
a number of API changes which have cause many packages to FTBFS.

Incomplete list of changes (based on looking at common build failures):
- Some fields in AVCodecContext have been removed and replaced with
  private options which can be set using the av_opt_set* APIs
- Most CODEC_* constants have been renamed to AV_CODEC_*
- The buffer constants FF_INPUT_BUFFER_PADDING_SIZE and
  FF_MIN_BUFFER_SIZE have been renamed to AV_INPUT_BUFFER_PADDING_SIZE
  and AV_INPUT_BUFFER_MIN_SIZE.
- The old resampling API provided by libavcodec has been removed. Use
  libswresample instead.
- The libavfilter/avfiltergraph.h header has been removed, include
  libavfilter/avfilter.h instead.
- The AVFrac structure (representing mixed rational numbers) has been
  removed.

Build log:
