scrcpy fails to start with Oppo Android 12 Device

[Yunheng]

• [ x ] I have read the FAQ.
• [ x ] I have searched in existing issues.

Environment

• OS: Ubuntu 22.04
• scrcpy version: v2.4
• installation method: Manual build with pre-packaged scrcpy-server
• device model: Oppo A17
• Android version: 12

Describe the bug

The adb and scrcpy setup works fine with almost every other device, except this one device that I have issues with. Another Oppo device (different model) has no issue.

Referencing #1518, I have tried to use the -m 800 and -m 1920 or even as low as -m 200 parameter but the same issue occurs.

All other devices that work use the tunnel-host parameter to connect to an externally hosted adb server.
adb devices -l on the machine running scrcpy shows the Oppo A17 device

scrcpy -Vdebug --no-audio -m 800 --tunnel-host=xxx
scrcpy 2.4 <https://github.com/Genymobile/scrcpy>
INFO: Tunnel host/port is set, --force-adb-forward automatically enabled.

I have also tried running it without the ---tunnel-host parameter, which results in the following:

scrcpy -Vverbose --no-audio -m 800
scrcpy 2.4 <https://github.com/Genymobile/scrcpy>

Since it would appear that --tunnel-host isn't necessary, I tried --list-encoders and used other h264 encoders too, but it still does not start scrcpy.

c2.mtk.avc.encoder
OMX.MTK.VIDEO.ENCODER.AVC
c2.android.avc.encoder
OMX.google.h264.encoder

log lines that appear to relate to scrcpy as follows:

I tried --list-encoders and used other h264 encoders too, but it still does not start scrcpy.

Does screenrecord work?

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

Oh yes, I did try screenrecord as well, but it doesn't seem to work.

"/system/bin/sh: screenrecord: inaccessible or not found"

ColorOS has a built in screen recorder though.
