There is no video encoder on your device.

[YANGKUN87]

您的设备上没有视频编码器。

How should this problem be solved？

[YANGKUN87]

您的设备上没有视频编码器。

Can Android devices install encoder?

[rom1v]

It cannot. Without video encoder, you cannot encode the video stream to be sent to scrcpy. So you need a device hardware which supports video encoding.
