Not sure if it's the same cause, but a friend of mine has a similar
setup, and she had the same sort of problem when streaming on Twitch.
Her solution was to set it to 4k 30fps and select recording video mode

Well.. that was extremely frustrating. I've seriously been going at this
for probably 16 hours, scouring the net for documentation and trying
other people's tutorials, wondering why my setup wasn't working as well

Only video4linux2 is supported, how well it works depends
primarily on the kernel driver.
You probably want a card that provides data in a pix_fmt
that your hardware encoder supports.

Ok, I did a lot more testing and have learned a bit more about my
hardware and the various names of audio devices. Also, I didn't mention
it in the previous email, but I did recompile ffmpeg from the latest

Hey Everyone,
I'm trying to stream from my GoPro into a USB capture device through my
Raspberry Pi 4 and send the feed up to Twitch or my rtmp server. After
