Hello,
I apologize for this long message, but it's necesary in order to
explain my problem.
Thanks to the advice of Steve I can record from a bktr device,
but the success in recording isn't as good as it could be.
When I record with sound (don't mind that video/audio codec I use
mpeg1, msmpeg4, mpeg4) the cpu spends alot of time in system context
as you can see below in the first example. Now in the second example
when I use the "-an" parameter (disable audio) the cpu has a more
moderate (read: normal) consumption.
I'm curious about this, why audio does encoding drop my framerate from
25fps and about 35% of cpu time to 19fps with 100% of cpu time usage?
Is there any other info that I can provide to help to debug this?
Perhaps an execution profile report.
Thanks all of you.
