Streaming video from Raspberry Pi to a powerful computer

Thanks to the hardware-accelerated video encoders in all modern ARM devices, including Raspberry Pi, a valid alternative to performing computer vision on board an embedded device is to use the device to just capture video and stream it across a network in real time to a PC or server rack. All Raspberry Pi models contain the same video encoder hardware, so an Raspberry Pi 1A+ or Raspberry Pi Zero with a Pi Cam is quite a good option for a low-cost, low-power portable video streaming server. Raspberry Pi 3 adds Wi-Fi for additional portable functionality.

There are numerous ways live camera video can be streamed from a Raspberry Pi, such as using the official Raspberry Pi V4L2 camera ...
