Waiting for RGB frames #34

Closed rtime2awaken closed 3 years ago

I'm getting a message Waiting for RGB frames any idea what I am missing?

Estimated / selected altsetting bandwith : 18 / 642.

Hi @rtime2awaken !

This looks like the RGB frame didn't get grabbed correctly. Could you confirm that you're able to see camera output by doing either:

gst-launch-1.0 nvarguscamerasrc sensor_id=0 ! 'video/x-raw(memory:NVMM),width=3264, height=2464, framerate=21/1, format=NV12' ! nvvidconv flip-method=2 ! 'video/x-raw,width=960, height=720' ! nvvidconv ! nvegltransform ! nveglglessink -e

or 

gst-launch-1.0 nvarguscamerasrc sensor_id=1 ! 'video/x-raw(memory:NVMM),width=3264, height=2464, framerate=21/1, format=NV12' ! nvvidconv flip-method=2 ! 'video/x-raw,width=960, height=720' ! nvvidconv ! nvegltransform ! nveglglessink -e

Let me know if you can see anything on the screen.

It has been fixed! I was using the v1 Pi camera that was causing the problem. Thank you for getting back with me. This is a great project.
