On Kubuntu 16.10 with 4.8.0-34 kernel I installed an app called Webcamoid to test and ran the following commands: $export LIBV4LCONTROL_FLAGS=3 && LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so webcamoid & file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/TextField.qml:635:5: QML TextInputWithHandles: Binding loop detected for property "text" file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/TextField.qml:635:5: QML TextInputWithHandles: Binding loop detected for property "text" libv4l2: error setting pixformat: Device or resource busy libv4l2: error setting pixformat: Device or resource busy VideoCapture: No streams available. $ v4l2-ctl -d /dev/video0 --list-formats-ext ioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'YUYV' Name : YUYV 4:2:2 Size: Discrete 640x480 Interval: Discrete 0.033s (30.000 fps) Interval: Discrete 0.067s (15.000 fps) Size: Discrete 352x288 Interval: Discrete 0.033s (30.000 fps) Interval: Discrete 0.067s (15.000 fps) Size: Discrete 320x240 Interval: Discrete 0.033s (30.000 fps) Interval: Discrete 0.067s (15.000 fps) Size: Discrete 176x144 Interval: Discrete 0.033s (30.000 fps) Interval: Discrete 0.067s (15.000 fps) Size: Discrete 160x120 Interval: Discrete 0.033s (30.000 fps) Interval: Discrete 0.067s (15.000 fps) $v4l2-ctl --device=/dev/video0 --list-inputs ioctl: VIDIOC_ENUMINPUT Input : 0 Name : Camera 1 Type : 0x00000002 Audioset : 0x00000000 Tuner : 0x00000000 Standard : 0x0000000000000000 () Status : 0x00000000 (ok) Capabilities: 0x00000000 (not defined) How to fix the problem?
