WARN: Killing the server...

Start by reading the Android server stack trace in ScreenEncoder.java, especially encode() at line 169 and streamScreen() at line 95, then inspect how MediaCodec output is dequeued. Reproduce with the reported OnePlus IN2023 on Android 12 and the shown max-size retries. Done means the encoding failure is handled or diagnosed without the server crashing, with a regression test if the existing test structure supports it.
