Hi all -<br>
Can anyone explain the difference in CPU usage between playing back a recorded show inside and outside of Mythfrontend?<br>
<br>
As far as I can tell, Mythfrontend uses mplayer to play back. However,
the CPU speed and overall performance is drastically different whether
I run inside mythfrontend or not. I they are using the same mplayer
binary.<br>
<br>
>From the command line, as mythtv user, mplayer -fs -zoom -vo xv <file> ... uses about 35%-40% of CPU<br>
<br>
>From inside mythfrontent, playback of the same recording uses from
%55-%85 of CPU and averages about %65. I believe I am using the exact
same mplayer command line options as used by MythTV within mythfrontent.<br>
<br>
I have even SSH'd in and run myplayer -fs -zoom -vo xv (with display
set to :0) so that mplayer pops up over top of myfrontend, to make sure
it wasn't just a resource usage thing with mythfrontent. Even with
mythfrontend running, top still shows only 35%-40% CPU usage when I
start mplayer from the command line.<br>
<br>
Where is the extra overhead coming from?<br>
