EZ-USB FX3 SDK Video Class Example - Frame Rate?
I am new to the world of video, and especially video-over-USB.
I have the EZ-USB FX3 SuperSpeed Explorer Kit. Everything is installed. I can compile new code and program the FX3 OK.
I am running the "USB Video Class example" from the SDK. This is the example that streams 4 frames of MJPEG over USB that shows the Cypress cup rotating.
I am using VLC as my video sink.
The problem I have is in understanding what I see. Why does the cup rotate so fast?? I thought that the programmed frame rate was set to 15 fps, but it appears much faster.
If I change the USB descriptors and the UVC probe control to 1 fps, VLC shows it at the same speed as when set to 15 fps.
