Problems Using glReaPixels

July 5, 2011 - 5:38am #1


I'm having a strange problem that the video bacground doesn't update when the markers not being tracked. I'm using glReadPixels to see if the video background has started and is configured properly and if i comment out the line glReadPixels line the app works like normal.

Any thoughts on the cause?

Hello Hidden,

I'm not sure what the issue is with glReadPixels. Have you tried querying the videoBackground image from QCAR's state object. There are some detailed descriptions of the STate and Frame classes here https://ar.qualcomm.at/qdevnet/api.

Thank you,
