Crash of the driver - Unknown pixelformat 0x00000000

tbrandysky commented 4 years ago

This is what I do:

install driver using DKMS method (everything goes well)
start ./webcamoid-8.7.1-x86_64.AppImage
create output device
start Teams and select the previously created video device
I can see the video in a preview from the webcamoid device but the driver crashes
I am not able to see video stream from the webcamoid virtual device anymore

This error is not reproducible, the call trace does not show nothing related to akvcam, it only shows a segfault in v4l2 driver, any more information or I can close this issue?
