Hi all!

I've met a problem: RVCamera.GetCamVideoMode returns duplicate resolutions (see attached screenshot):

What is the reason?
Is there a way to fix it?

These modes are not exactly identical. There are some video mode parameters that are not listed in item captions.

In the new version of RVMedia, we changed web cam video mode processing. Most probably, the new version will display only one of these almost-identical-modes for your camera.

I planned to upload the new version today, but found a problem in Lazarus (it looks like this is a Lazarus bug. I found a workaround, so the new version will be released soon).

Well, waiting for a release.
And can you tell me what is the difference in these modes? Just to know.

Most probably, just a different structure is used internally.

This problem was fixed in v7.2
