hello
I’m trying to stream on twitch by sending a 6000k bitrate (maxrate), but the codec doesn’t seem to take my settings into account. I end up with a bitrate of 10,000k and twitch crashes because I’m sending it too much bitrate.
Do you have any idea why?
I’m on Jetson nano 4gb

Someone have a good configuration for 1080p60fps via twitch ?
