Scaling and mixing videos

[longkas]

Hello,
My pipeline uses compositor to mix multi frames,  I have tested 4 x 1080p
frames downscaled(by set sink pads prop of the compositor) and the fps drops
a lot, while the CPU usage still not hitting top. How can I improve the
performance for my case
   
Thank you

I first try to use glvideomixer to replace compositor, but it uses a lot of
CPU even no video pushed to it , the  program is running on intel 7700 which
has an HD630 graphics card, is that normal?

Then I added every one videoscale on each video frame, it improves but when
I raise destination FPS to 60,  it can not satisfy the expectation while the
cpu usage is still 50 percent.

I did not try to use glcolorscale instead accroding to previous glvideomixer
result, please help me , thank you

BR
