It seems to me that GStreamer choose libav over ffmpeg when made the
1.0 release.  That is why there are:
  gst-ffmpeg-0.10.x
  gst-libav-1.x

I Agree.

I quick tested gst-libav linked with ffmpeg from Guix,
it does seem work fine, but may need more testing or some
confirm from upstream.

I think it's great to use system ffmpeg, if no problem occurs,
or we can use system libav (to be packaged) in Guix instead.
