Check out how you can use an ElGato CamLink (or other similar device) to live stream your video feed, even in the field. These devices use no external power, and convert your HDMI source to a USB input, which is then recognized by your PC as a standard webcam. These are great for use in the field, where you only need a laptop, camera, HDMI converter and WiFi hotspot (your phone) to live stream from anywhere.
