Currently both the video bit-rate and resolution/quality can only be configured when initializing the Recorder, which means it needs to happen before Camera initialization.
I'm working on a library where users can pass a custom video bit-rate to the startRecording(..) function, which would not work with CameraX as I'd need to re-build the session/use-cases to change the bit-rate at that point since the camera is already bound/running.
As far as I'm aware, you are using an OpenGL pipeline to forward the frames to the actual Encoder/MediaCodec instance, so if I'm not missing something it would be possible to configure bit-rate after the Camera has been started as the MediaCodec has not yet been created by then (otherwise asPersistentRecording() wouldn't work, no?)
I think it'd be great to have bit-rate and resolution/quality be configureable after the VideoOutput has already been created (but before we call startRecording())
