We had lavc / ffmpeg and had to remove because of licensing issues.
Even if we add them back, software decoding is currently broken, so it
wouldn't help.

We're only doing hardware decoding, so it might be indeed a bug in our
gst-hybris stack. Would you mind opening a bug for that? I know Jim
changed the dequeue timeout values before, and that directly affects
the amount of cpu used, so we might have a regression (probably need
some further fine tuning).

Streaming from nfs/samba should probably work already, but we'd need
someone to give that specific url to the mediaplayer-app.
