Re: [Audacity-devel] [Libav-user] Requesting help to port Audacity to recent FFmpeg

[Martyn S. <mar...@gm...>]

Thanks Richard, I think you have made a good summary here.

Audacity is attempting to make itself independent of the changes in 
libav and ffmpeg by using Gstreamer as a third-party.  I support that 
(for now at least).  We want the functionality without the hassle.

TTFN
