Is there a way to capture only a frame or screenshot rather than a video stream?

I am looking for a minimalized version of what the video stream part of scrcpy does.

It is apparently not so straightforward to take a screenshot of an android device outside of the android context. I imagine similar frustrations occurred while learning how to attain the video stream. Is there a way to only attain one frame or a screenshot at the time of a request?

The issue does not name files or tests. Start by tracing scrcpy’s existing video-stream path and the Android-side screenshot request described here; done means a request can return one frame without maintaining a video stream, with behavior verified against the relevant existing stream behavior.
