It looks like it is because the application didn't release IAMStreamConfig
after used. So the video device wasn't released after the first video chat.

libv4l2: error setting pixformat: Device or resource busy
0020:0254:err:qcap:set_caps Failed to set pixel format: Device or resource
busy.
0020:0254:err:qcap:qcap_driver_init Failed to set pixel format: Device or
resource busy

Should we consider it as an application issue? But it works well on Windows.
