Comment (by humdinger):
I think luroh on IRC was right: MediaPlayer is starving for CPU.
Something's not as efficient in ffmpeg since the update in hrev43830.
Where in the past the problematic files could be played back with my
hardware, now they can't anymore. ffmpeg is single threaded, right? If I
disable one CPU, CPU usage goes shortly up to 100%, then the video pauses
until the next short spike and so forth.
When both CPUs are activated, their usage are around 50%, so...
I can still play back smaller files, i.e. lower bandwith.
