No screen, Encoding error on SDMC android box

[aggo1036]

Environment

• Windows 10 64-bit Pro
• scrcpy 2.7
• Windows release zip-file.
• SDMC DV8919x
• Android 12

BUG. Screen is not rendering. [server] ERROR: Encoding error: java.lang.IllegalStateException: null

Description. Wireless debugging is hidden from the supplier. So instead ADB WiFi 3.3.160 was installed through USB and set as autostart on boot. I can now seemingly connect as if wireless debugging was installed/enabled. When accept adb connection the screen is shown as "USB Debugging" if that is of any interest.

Terminal output in a code block.

If I just go "scrcpy -m640" everything comes to a halt at INFO: Texture: 640x360 same as before. Any ideas of where to go from here?

You can try with another encoder: https://github.com/Genymobile/scrcpy/blob/master/doc/video.md#encoder

This is what I got

Thanks it worked now! Lower fps and size for better experience over low bandwidth.

scrcpy --video-codec=h264 --video-encoder=c2.android.avc.encoder --max-size=860 --max-fps=30 --no-audio --keyboard=uhid
scrcpy --video-codec=h264 --video-encoder=OMX.google.h264.encoder --max-size=860 --max-fps=30 --no-audio --keyboard=uhid

Solved.
