@ccs-hello Indeed, yes, I scanned the question too quickly and thought it was about streaming from USB webcams that do their own MJPEG. But the actual topic of trying to do video output from an MT7688 is indeed not sensible. The cheap "not quite Android" chips used in the dongles, or a pi (if you can get the GPU actually turned on for the desired compression), do make much more sense for that... and not just in the dedicated computational paths, but in having HDMI output!

I don't know about vpn, but the Omega2 doesn't have any sort of video output, you'll definitely need something else to handle playback.
