I have the DJI Osmo Pocket 3. You can find them a little cheaper on eBay. In regards to the actual camera, there is probably not a lot of cameras that can compare to it. The automatic stabilizer and the face-focus are something that I have not seen on any other cameras and in the creative combo set you also get a few things that are perfect for vlogging and livestreaming such as the bluetooth microphone, which can be directly attached to the camera.
There are lots of mounts you can find on Amazon which fit perfect for the DJI Osmo Pocket 3 and they are not that expensive either. One thing I would suggest you to buy is a screen protective cover and a protective cover for the lens. I got that too.
Tried irl streaming with my Nokia G42 phone and Prism Live and it was a small nightmare with my phone overheating, connection dropping and yeah, had a harder time controlling the lightning and how I look in comparison with filming indoors. Later saw some dude with iPhone, shitloads of extra hardware attached and some filter app that instantly transformed that ugly nerdy dude into a kpop idol and I realized I need better hardware and software. So indoors only for me now.
People just make it complicated. A very good app for IRL Streaming is IRL Pro (
https://irlpro.app/). Lots of IRL Streamer use this one as it is not as heavy on the battery and you can also adjust the bitrate right on your stream, which is especially good if you are having a bad connection. Pair that with a power bank in your backpack connected to your phone and you can most likely do a 24 hour stream with your phone just with IRL Pro. Seriously, you don't need big IRL Backpacks with LiveU anymore (like this one:
https://www.unlimitedirl.com/backpacks). It can all work well, just with the IRL Pro App.
Now, doing IRL Live Streaming with a DJI Osmo Pocket 3 is a whole different setup and requires more sophisticated planning in terms of battery management, internet provider setup etc. - It is possible but you would need to have it all figured out perfectly, as otherwise you may run into issues while doing your live stream (choppy audio/video, overheating).
If you want, I can help you with setting up IRL Pro for your phone. Just let me know.
