Cannot work with external camera under macOS (Mojave)

[eugenn]

I've got the following error when try to run under macOS

"python[12359:946679] *** AVCaptureSession warning: Session received the following error while decompressing video: Error Domain=NSOSStatusErrorDomain Code=-12903 "(null)". Make sure that the formats of all video outputs are properly configured."

It happens when I use an external camera, but when I change device id to 1 (inner camera) it works well.

Can you share your code. This external camera is connected through USB? Or you are using an ip address?

import videoflow.core.flow as flow
from videoflow.core.constants import BATCH
from videoflow.producers.video import VideostreamReader

reader = VideostreamReader(url_or_deviceid=0, nb_frames=30)

fl = flow.Flow([reader], [], flow_type=BATCH)

fl.run()
fl.join()

True, camera connected through USB (logitech c922)

This code crashed in macOS but works fine in Ubuntu (python 3.6)
