What's the rule for padding data for multi ROI within FX3 U3V sample?

[yiwa_4244806]

The original FX3 U3V sample only supports one format stream, so I tried to add the second format data(multi ROI) within it.

But what's the rule when different format?

It seems that the smaller iamge payload should add 4 bytes padding data when it works with two format?

You'll need to add an extra descriptor for different format.

Tks for reply!

But when I added the second Image data, I found I have to add the 4-bytes-zero data, or the player cannot display the image corretly.

Why? Puzzled*_*
