Hi Sebastian, There is a bit of a misconfiguration in your Configuration manager file.
for the .type: capture.device.VGA.type=VGA2PCI It should either be: capture.device.VGA.type=EPIPHAN_VGA2USB if you want to use the code we have provided for handling scaling and unplugging and replugging without a hardware dscaler or if you just want to use the v4lsrc plain like you are using on the command line you could use: capture.device.VGA.type=V4LSRC For both of these above options you will need to add capture.device.VGA.src=/dev/video0 Or if you want to use the custom producer you will want the .type to be: capture.device.VGA.type=CUSTOM_VIDEO_SRC and the .customProducer line to be: capture.device.VGA.customProducer=v4lsrc device=/dev/video0 ! queue which is almost exactly the same as the .type being V4LSRC so if I was you I would use that one.
