OpenCV error while running FaceLandmark with webcam #632

Open guygrinberger opened 5 years ago

guygrinberger commented 5 years ago

I have installed OpenFace using the instructions provided for Ububntu on a fresh Ubuntu 18.10 install. To test it I ran: ./bin/FaceLandmarkVid -device /dev/video0

It worked well and I saw the program running live with my webcam.

I restarted the system and tried to run it again the same I did before and got an error: VIDEOIO ERROR: V4L2: Pixel format of incoming image is unsupported by OpenCV I ran v4l2-ctl -d /dev/video1 --all. The pixel format of the webcam is 'YUYV'

I tried searching for this issue online but unfortunately didn't find a solution.

This seems more like an issue of Ubuntu video interface or OpenCV rather than OpenFace. Does opening a webcam in OpenCV work outside of OpenFace?
