-----------------------------------------+-----------------------
 I have VAAPI acceleration configured for TV playback and this works fine
 for first channel watched during LiveTV (~20% cpu usage).
 After switching channels, cpu usage goes up to ~140% and 'perf top'
 introduces swscaler library being used. Stopping LiveTV and reentering
 works around the problem.

 mythtv 2:0.27.4+fixes.20141108.0f0e678-0ubuntu0mythbuntu2

 I watch DVB-C HD (H.264) content.
