Description Mathieu Duponchelle 2017-07-08 00:47:41 UTC
If you can't decode an animated gif, you can't decode a gif,
so stop squatting GST_RANK_SECONDARY for that format, libav
does a better job.

You should probably comment it out like image/jpeg.

I guess we should also add on our todo list to have a non-ffmpeg gif decoder because of the licensing problems with ffmpeg.

See https://bugzilla.gnome.org/show_bug.cgi?id=737339 for a non-ffmpeg gif decoder, and was closed by Mathieu as WONTFIX a while ago

It was closed because it was basically a dysfunctional copy paste from ffmpeg, not advertised as such.

We may have a rust gif decoder at some point :) https://github.com/sdroege/gst-plugin-rs/issues/11
