@xiangyu.li:matrix.orgXiangyuHello,how can I get the ID and name of the currently connected camera? I don't think it is a good way to traverse the collection to determine whether the image is empty03:53:06
@ravazquez:matrix.orgravazquezAs far as I understand there is no way to do this in openCV14:16:58
@ravazquez:matrix.orgravazquezI had to use dxshow or MediaFoundation for this14:21:04

@vshmidt:matrix.orgvshmidtHi! First thanks you guys for a greate work with opencvsharp!!!14:23:28
@vshmidt:matrix.orgvshmidtMaybe you have some time for a help with VideoCapture performance. I stuck into same problem with low FPS on Read method https://github.com/opencv/opencv/issues/9084. I have tried to solve it with setting Exposure/Fps/FourCC and etc but with no luck. My Read performance with Logitech 920 camera is only 15 frames per second. Much of time (about 60ms) takes Retrieve (RetrieveMat) method. Can not understand what can be a problem but Python code is reading cemera frames with ~30 fps on a same environment. I have splitted out Read to Grab and Retrieve to separate thread and introduce two threads for a Retrieve. This gives about 30 fps but it looks like a hack. Maybe you have some information about? How to increase Read FPS to number more than 15 frames?14:31:10
