Tons of Error with my Xiaomi 9T Pro (K20 Pro)

[jasonisaddicted]

Bunch of errors pop out.

Everything works fine with my old Note 8 (Exynos) until I got this new phone.

I can still mirror but It's very laggy, drop frames

These are the codes.

The error backtrace is harmless (see #994).

If it's laggy, try to reduce the definition (for example scrcpy -m1024). Either your device is not able to encode in real time at this definition, or your computer is not able to decode fast enough.

Hm... It works fine with my Note 8 (Exynos version), no drop frames, no problem at all...

Got this new Xiaomi 9T Pro for better gaming experience, and stream some games with my friends and turned out unable to decode fast enough? That's a shame..

Tested on ApowerMirror App (paid version), wireless, it is running smoothly.

Will try to tweak the settings and see how it goes.

For reference of my PC rig:
Intel i7 8700K
32GB RAM
Samsung Evo 970 500GB
GIGABYTE Z390 M
Aorus GTX1080ti 11GB

Ok, tested with this setting and the performance is the same.

cd c:\Mirror
adb devices
adb connect 192.168.0.161
scrcpy -b 1M -m720 --always-on-top

For my previous setting for my Galaxy Note 8:
cd c:\Mirror
adb devices
adb connect 192.168.0.118
scrcpy -b 32M --always-on-top

ApowerMirror app (PAID version) works fine with both devices, additionally, I could choose ULTRA setting for 9T Pro and my Galaxy Note 8 Can't.

No clue why a better phone, and it's snapdragon 855, could perform so poorly, or maybe it's because of Android 10? I seriously got no idea. I really enjoy using this, hope there will be a solution with this...

OK. Several tests to figure out the problem.

Could you test over USB (instead of wifi)?

Enable framerate stats (Ctrl+i in the scrcpy window, logs are printed in the console).

Record the file: scrcpy -r file.mkv, then play it with VLC. Is it laggy too?
