Option to record received feed instead of only recording on device

• I have checked that a similar feature request does not already exist.

Is your feature request related to a problem? Please describe. I've noticed that sometimes an app may show up in the regular scrcpy window, but when recording, it fails to record. I believe the underlying issue is the app, not scrcpy, but this also makes it hard to record certain apps that break on-device recording.

Describe the solution you'd like My solution to this would be to add an option to record the feed that scrcpy is receiving for the regular window instead of only relying on on-device recording.

Describe alternatives you've considered Just recording the window with OBS

Additional context The app in question is My Little Pony: Magic Princess, and my device is a google pixel 6a running android 17.

I might be misunderstanding what the issue really is, but it's really strange that I can see the app in the window, but the app goes black in the recording.
