Is it possible to bind Preview, ImageAnalysis, and VideoCapture at the same time? Combined in pairs, all possible combinations (ie. Preview+ImageAnalysis, Preview+VideoCapture, and ImageAnalysis+VideoCapture) work perfectly fine but binding all three together throws the following exception.
java.lang.IllegalArgumentException: No supported surface combination is found for camera device - Id : 1. May be attempting to bind too many use cases.

Is there any workaround that allows me to use ImageAnalysis and at the same time record a video?
There are limits to the number of simultaneous outputs that are due to the camera hardware pipeline's scaler unit limitations.
In general, 3 parallel YUV outputs aren't supported outside of high-end devices.
You can look at the many tables here: https://developer.android.com/reference/android/hardware/camera2/CameraDevice#createCaptureSession(android.hardware.camera2.params.SessionConfiguration)
and see what kinds of parallel outputs can be set up, on the various hardware levels (PRIV and YUV are what these usecases operate on).
A FULL device can do it, as long as the analysis runs at 640x480 or lower. But LEGACY and LIMITED cannot.
That said, you can use ImageAnalysis frames to drive a preview, but it's certainly a bit less convenient - may require using the NDK or other annoyances.
