Bug#888332: audacity: FTBFS with FFmpeg 3.5

[Jaromír Mikeš]

Hello audacity developers,

current audacity release doesn't build with upcoming ffmpeg 3.5.
As we in debian build audacity against system-wide ffmpeg it can be serious
problem in near future
and audacity might be removed from debian archive.

best regards

> Hi,
>
> Your package FTBFS with the upcoming version 3.5 of FFmpeg. In FFmpeg 3.5,
> there are a number of API changes which will cause many packages to FTBFS.
> For this reason I have uploaded an early development snapshot to
> experimental
> before the 3.5 release in an attempt to fix some of these a bit quicker.
> While 3.5 has not been finalized and the ABI is not stable yet, there
> should
> not be any significant API breakages before the release.
>
> 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 haupcommings 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.
