I'm trying to find out how useful FUJIFILM X-T4 will be as a streaming device.
According to the specs it is able to record decent DCI4K 60 fps 10bits.
It is also capable of emitting it properly via the HDMI interface.
It have USB port which technically should be capable of transmitting the video while acting as UVC (Look Sigma fp for example) Instead there seems to be only Tethering mode available (either via the USB or WiFi). I've find out that it might be the PTP protocol.
So here are my questions: What is the "tethering mode"? What are the PTP live view image properties?
