Description Arnaud Vrac 2016-09-30 14:37:30 UTC 
Hi,

I have an audio sink that can take compressed audio and render it directly. In playbin2 no decoder is plugged between the demuxer and the sink, allowing hardware offloading of the audio decoding.

However in playbin3, the fact that the sink can decode audio is ignored and a decoder is plugged in, which is sub-optimal.
Comment 1 Edward Hervey 2016-10-08 15:59:26 UTC 
We need to figure out a better autoplugging signal for decodebin3, which is the reason why playbin3 can't handle that use-case right now.

The reason are explained in https://bugzilla.gnome.org/show_bug.cgi?id=769079#c15 and other comments of that bug
