S Stevewidg New Member Licensed User Longtime User Dec 1, 2013 #1 Hi, I've searched through the forums and there are several mentions on this topic, however I believe my question is a little different. I have seen apps that enable a USB webcam to be used as a rearview camera for cars, and I have downloaded the Webcam test app from http://www.infinitegra.co.jp/en/solution/AndroidApp1.htm and it certainly enables a Logitech C270 webcam to display on my Galaxy Note. So I know it can be done. Of course I would like to know how this can be done for a UVC compliant webcam in B4A. Video Class is listed in the USB Host library, so I'm hoping it might appear as an additional camera in the Image Capture Library. I'm very new to B4A and Android, so am concerned it may be a bit much as a 'newbie' project. Any help or advice greatly appreciated. Many thanks Steve

See this discussion: http://stackoverflow.com/questions/8963897/use-usb-camera-on-android-application Click to expand... Thanks for speedy response Erel. I did understand about requiring UVC and support ( i.e. 4.2) Maybe Ive misunderstood what UVC stands for. A 'proper' driver for UVC should be able to read any UVC compliant camera shouldnt it? ( It seems to in Windows, but I'm willing to bet there are a lot of cameras out there that arent compliant.) So I guess to re phrase my question has any body written a generic UVC driver thats available in B4A. Regards Steve Upvote 0

H hayderOICO Member Licensed User Longtime User Jan 14, 2014 #4 Hi All I am also interested in this! Is there a way for the B4A to use video feed from a camera other than "front" and "rear"... and UVC is standard on linux distros... in fact the front and rear cameras on android devices are also UVC mostly?
