Low-latency screenshot from Android emulator

I'd like to grab the screen 10 times a second to feed it into a computer vision model.

Running screencap in a loop in adb shell is too slow.

Other answers have suggested reading from /dev/graphics/fb0, but my emulator does not have this file.

Ideas for how to do this?

As it is an emulator wouldn't it be simpler to directly capture the screen on host side? – Robert Mar 23 '22 at 14:56
Yeah, that could work. Ideally I'd like something I can run both on an emulated device and on a real device connected through USB. – random_stuff Mar 23 '22 at 15:02
But your title clearly limits the question to emulators. For real devices check out scrcpy – Robert Mar 23 '22 at 15:05
Does this answer your question? screenrecord not working in emulator – alecxs Mar 23 '22 at 21:38
