Toggle Between Two Cameras in Vision Processing

[PhilBot]

OK, some updated information.

I can get both USB Camera streams to start if I go low enough in image size.

The requested frame rate or compression don't seem to have any impact.

If I set BOTH cameras to 160x120 they work....

However, if I put just ONE of them up to 320x240, the second stream does not start.

This is oddly annoying, since the system is quite capable of sending one stream at 640x480. If the system can handle an uncompressed 640x680 image (307K pixels), the you'd think it could handle two 320x240 images (153K pixels), or certainly a 320x240 image plus an 160x120 image (115K Pixels).

Thanks Greg, for the insight.

Phil.
