Camera) Both my GF and I have the issue when the webcam is opened in one scene and you switch to another scene, you have to manually go into the new scene and open the webcam, disable it and enable it again to make it work. So as you say,it breaks when swapping between scenes. Something OBS classic did not do.
If you want to use the same video device with different settings in different scenes.. don't, you can't. Use the same source with the same settings (same frame size, same frame rate etc) or the 2nd device will die.
Now, it's possible you've created two copies of the same source that ARE the same, but are distinct in OBS (the source is a duplicate and not a reference). This might also cause the device to fail. To test, delete all instances of the camera, make a new one, and in every scene where you want to use that camera, add it as a reference to the existing source, not a new device, not a duplicate.
I have one gigabit of upload and download speed and I can run any game thus far released on max settings with little to no lag issues.Is there no way to get this without using the program? (I use it for Twitch)
If you're streaming on Twitch, use TwitchTest. Your ISP's speed rating does not mean anything for streaming, your speedtest.net results are not relevant to streaming, because they don't test the thing that needs to be tested to know how high a bitrate you can stream to twitch, which is what TwitchTest tells you.
Audio) If I change my audio device in one scene to my headset, for example, it does this in every scene. Old OBS had it locked to a profile, meaning it was very easy for me to swap between my Oculus and my Headset. Here it seems like it's a task and a half. What would your suggested way of adding them be to the individual scenes? It's for game audio and microphone.
Thank you once again.
Never used OBS Classic so I'm not sure about what functionality you're talking about here.
If you have multiple, separate audio devices you might use, you can keep them together in a scene. You can hide/disable them with the eyeball icon if you're not using them. Although if they're not being used at the time (not carrying a signal) then you may not even need to use that-- just keep them both in the scene, and when you switch audio in Windows (or however you're doing it) OBS will pick up the signal from the previously inactive device, and the old one won't be being used, so should be silent. As long as you're not doing anything you aren't supposed to be (trying to monitor audio on your system default, for instance) there should be no problems making changes like this.
As I mentioned before-- you can set multiple audio devices in Settings > Audio, for game and for microphone. These will always be active, in every scene.
You can also add sources directly to scenes, and copy/paste them into multiple scenes as required.
