While trying to play the Adam Carolla audio podcast (​http://theadamcarollashow.libsyn.com/rss) it skips and stutters before exiting with an error message about video buffers, e.g.

Same problem can be found with mp3 podcast files from here: Tom Barnard Podcast ​http://www.tombarnardpodcast.com/feed/podcast/

While trying to play, file plays as if it's on fast skip forward, and then after 20-30 seconds MythTV errors with, "Video frame buffering failed too many times "

Running MythFrontEnd? fixes/0.26 (v0.26.1-1-g6a46ea0)

The mp3 files seem to play fine when using other playback means - just not MythTV FE.

This problem is still occurring, even after upgrading to 0.27.

Don’t attempt to play the video streams for mp3, flac, off and m4a container.

FFmpeg incorrectly detects the artwork in those file as MJPEG, which myth would then attempt to play.
A nicer fix would be to display that image instead.

Fixes #11597
