[mythtv-users] How can I tell the native X/Y size of a recorded file?

[Mark Knecht]

Assume I've already recorded some material and the file resides on my
backend server. How can I tell what the native X/Y video size of that
file is?

I'm assuming that to reduce the CPU usage on the frontend that is
displaying this file it would be better if I didn't rescale the
recorded file but actually set the resolution of the display screen to
the same resolution. Is this true? If so I'd like to try two things:

1) Playing the file full screen after resetting X to run at that
resolution. (If possible)

2) Start mythfrontend with --geometry set to those values.

Just wanted to try an experiment to see how it impacts CPU usage.

Thanks,
Mark
