Remarks
One single stream used for combined purposes of preview, video, and still capture.
For such multi-purpose streams, the camera device aims to make the best tradeoff between the individual use cases. For example, the STILL_CAPTURE use case by itself may have stalls for achieving best image quality. But if combined with PREVIEW and VIDEO_RECORD, the camera device needs to trade off the additional image processing for speed so that preview and video recording aren't slowed down.
Similarly, VIDEO_RECORD may produce frames with a substantial lag, but PREVIEW_VIDEO_STILL must have minimal output delay. This means that to enable video stabilization with this use case, the device must support and the app must select the PREVIEW_STABILIZATION mode for video stabilization.
