Oh, I think I missed to catch some errors to retry in #2947.

Could you please replace this file in v1.22, and post the whole console output?

OK, great, the retry mechanism now works in your case. But it seems your device can't encode the screen at any definition.

You could try with a different encoder: https://github.com/Genymobile/scrcpy#encoder

Also, does screenrecord work?

adb shell screenrecord /sdcard/file.mp4
adb pull /sdcard/file.mp4

[Fitertom]

if anything on the official firmware miui 12.5 scrcpy worked without problems

[rom1v]

OK, if screenrecord does not work, then there's definitely a bug in the ROM.

I have a built-in screen recording on my phone and from the very beginning it doesn’t work, maybe it’s somehow related, but third-party recording applications asked for access to broadcast / screen recording, it’s possible and it’s somehow connected with this, maybe the protection of android 12 does not allow third-party programs to record screen without permission and these applications simply do not request it

[aa755]

I was getting the same error. once I started screen recording on android just once and stopped, scrcpy also started working.
