DIY IRL Streaming Bike Backpack Setup: RaspberryPi4 / GoProHero7 / FFmpeg

Описание: This is the first incarnation of my IRL streaming backpack for biking around. It utilizes a RaspberryPi4 with a usb capture card and a GoPro Hero7 Black, along with a custom FFMpeg command to capture and then relay out to Twitch. The Pi and the capture card are capable of 720p at 30fps, however do to prefering a smooth glitch free stream, I have it set to 480p stretched to a 16:9 resolution at 2000kbit. Obviosuly with a better connection or personal preference these numbers can be tweaked.
Any question comments or suggestions leave them below and I'll do my best to answer. I was inspired to try and build this after watching Terry Barentsen's IRL bike streaming setup.


I am not too worried about the heat generation for the RPi while in the backpack as I had this exact unit running outside in the summer heat for over a month straight.
