IllegalStateException on MediaCodec.native_dequeueOutputBuffer()

Scrcpy recently stopped working for me, I'm getting an error that there are multiple devices but when I run "adb devices" there is only one listed

 $ scrcpy -b2M -m800

Restarting adb daemon did any help?
adb kill-server
adb start-server

tried restarting adb multiple times... no change

I'm getting an error that there are multiple devices but when I run "adb devices" there is only one listed

This is an error printed by adb on adb reverse over wifi on old devices, but _scrcpy fallbacks to adb forward, so this is not the reason of your error, everything is ok for this part:

See #5

java.lang.IllegalStateException
  at android.media.MediaCodec.native_dequeueOutputBuffer(Native Method)

This is the real error. And is the same as #465, so I'm closing as duplicate.
