A:AnswerYes, you can live stream with the HERO9 Black. It will stream to Facebook, YouTube (if you have 1,000 or more subscribers), Twitch, the GoPro subscription platform, and other RTMP platforms.
A:AnswerThere's nothing in the GoPro camera itself that would automatically move/rotate the camera itself to follow a person around as they moved. There may be third-party tools that would allow this to be done though.
A:AnswerBe advised: the GoPro App (now called Quik) does NOT allow you to livestream to a branded YouTube channel from Android devices. No option pops up to select a channel within your Google account.
However, it DOES work from iOS devices. GoPro support started to assist me with this issue and then stopped responding. There are YouTube videos from others documenting this issue, but even the most recent Quik app version doesn't allow Androids to livestream to anything but the generic channel associated with your Google account. I have to borrow an old iPhone whenever I stream to YouTube from my GoPro Hero 9, which is incredibly annoying.
A:AnswerNo, you can use a GoPro without using a smartphone. The phone will add on some additional features like being able to preview shots, control your camera remotely, and make it easier to view and share the content you record, but all of the core functions of the camera can be controlled directly on the camera.
