2015-06-29 01:31:42 -0600 | asked a question | VideoCapture limited to 20 usbcam help Windows c++ opencv 2.49 I have a project that requires opening 25 cameras and capturing a frame. I am using Logitech c920 webcams. I am capable of opening 20 cameras but if I try opening 21 cameras I error: Unhandled exception at 0x5eda8fe2 in Box Draw.exe: 0xC0000005: Access violation reading location 0xe436ebe3. Linux c++ opencv 3.0 I tried Linux and the limit of webcam is 8. I error out with Linux with v4l : index # is not correct after the 8th webcam is open. Linux and windows both see the webcams and the windows Logitech software can open each stream. I believe there is a quick fix to both Linux and windows but I don't know where the files are to increase the camera limit to over 8 for Linux or 20 for windows. tried editing test_video, test_video_io in windows tried editing cap_v4l in Linux Any hints or ideas would be greatly appreciated. |
