Performance:
All tests are done on an Intel i7-2600S (with Turbo Boost disabled) using the
integrated Intel HD 2000 graphics processor. The mothreboard is an ASUS P8H77-I
with 2x2GB CL 9-9-9-24 DDR3 RAM. The capture card is a Cisco test card with 4 HDMI
inputs connected using PCIe2.0x8. All video input streams used for testing are
progressive HD (1920x1080) with 60fps.
I did a quick test here with a radeon HD 7750 GPU on a i7-3770 CPU, using an UVC
camera at VGA resolution and nouveau driver (Kernel 3.10.3).
qv4l2 CPU usage dropped from 13% to 3,75%.
It sounds a nice improvement!
That is good to hear. My results where achived using the 3.9 and 3.10 kernels
although I belive that the hardware and opengl driver affects performance the most.
With such a good hardware and relatively low resolution, you wont see that much of a differance :-),
Yes, I know ;)
but it is a nice improvement indeed. Anyway, nice to get additional tests!
Yeah, that was mainly the reason for the tests: to reproduce it with a
different setup than yours.
