Hello, amazing work!
Does Raspberry PI0w has enought resource for streaming video ?
The size of Pi0 is smaller but I'm not sure about the performance, it's fully compatible?
Can I use with usb dongle?
Yes Pi0w has enough power to run UAVcast, telemetry, video at the same time.
Several guys already using this setup.
However, CPU usage is arround 50 > 100% but it works.
