adb cannot display matched mobile devices in time

[yk2911533608]

Operating system win10 64 bit
scrcpy version: 3.1
Mobile phone model: oppo Reno
Android 11

Problem: After using adb pair to pair the phone, and then using adb devices, the device list will not be displayed. It takes a while or repeated use of adb pair and adb devices before "Connecting through wireless debugging" will be displayed on the phone. Is there any way to optimize this problem?

Looks like a bug on the device.

Anyway, I always find wireless pairing cumbersome. It is easier to plug the device once over USB to enable adb over tcp/ip: https://github.com/Genymobile/scrcpy/blob/master/doc/connection.md#tcpip-wireless

One more question：Which command can meet this scenario: cast the screen to the computer to record the video, the audio is output on the mobile device, and the sound can be heard in the recorded video. This is the effect in version 2.7, but it won’t work after upgrading to 3.1.

There were no changes related to that. By default, the audio should not be output on the mobile device (but maybe it was on an older version of your Android system, as a bug).

However, for Android 13+, you can use --audio-dup: https://github.com/Genymobile/scrcpy/blob/master/doc/audio.md#duplication

scrcpy --record=file.mp4 --audio-dup

If you want to record without live playback:

scrcpy --record=file.mp4 --audio-dup --no-playback
