--- Comment #16 from Arjen Veenhuizen <arjen.veenhuizen at tno.nl> ---
It looks like I found a case where it still does not work (using GIT master of
today). The attached sample file contains VP8 video and OPUS audio:
ffprobe 2016-02-03_-_09-54-34.mkv

The source of the clip is a stream generated by Google's libwebrtc for Ios
received over RTP, depayloaded and muxed using matroskamux.
The file plays just fine with ffplay, but
playbin uri=file:///storage/2016-02-03_-_09-54-34.mkv shows the following
output:

Is this an issue in matroskamux or matroskademux? I suspect the latter but
maybe something goes haywire while muxing.
