High frontend CPU load playing DVB-T radio recordings

Description

Reported on MythTV-users but no response. Posting here so that it doesn't get overlooked.

http://www.gossamer-threads.com/lists/mythtv/users/565232#565232

mythfrontend version: fixes/0.27 [v0.27-178-g6b14852] F19 x86_64 local build based on modified rpmfusion specfile

During playback of a radio recording atop is now showing 98% CPU load, mostly as 'idle'. No visualiser active, blank screen. The audio sounds fine, and keyboard response is quick.

Playing an SD TV recording shows load typically around 25%. nVidia 304.119, GeForce? 7500LE, no VDPAU.

My build from the same tarball for my SL6.5/KDE-unstable/elrepo-kernel/i686 laptop has CPU load around 10% during radio playback - much more reasonable. Intel GPU.

These builds predate commit c64141b0c0b7118ee28be2441374727a1af7c44c on master, which targeted 'low bitrate' playback.

John - is this still an issue? I don't see a load problem with master.

No. Playing a DVB-T recording made today, atop shows mythfrontend at 8% Must have been fixed somewhen. 6 years is a long time. Thanks.
