connect the mobile phone through ws to perform Scrcpy operation, and report an error Error: Socket closed after stopping.

[greathh]

1.Use the demo（v0.0.20）, run it location
2.Connect the device through ws and perform Scrcpy operation. After start, stop reports an error.

The main problem is that during the scrcpy process, the operation on the web interface is very slow and it takes a long time to operate.

But when operating on the device, the web interface renders very smoothly.（So there should be no problem with my network）

So how can I make the connection through ws as smooth as using webUSB?

thanks！

When stop is clicked, the console reports an error. The number of errors reported each time is based on the number of times the device is operated on the interface.

Use the demo（v0.0.20）

Are you on v0.0.20 tag? Does it work in 0.0.21?

When stop is clicked, the console reports an error.

This means those packets are not sent before the ADB socket was closed. I don't think the error is from the WebScoket connection, because WebSocket doesn't have any flow-control API (it has a really bad API design). But I also don't know where the error could be coming from.

the websockify.js server

I guess there may be a large number of mouse hover events on the interface that cause the lag, but on the phone there are only touch events.

Error: scrcpy server exited prematurely at eval (webpack-internal:///../../libraries/adb-scrcpy/esm/client.js:109:27) at async AdbScrcpyClient.start (webpack-internal:///../../libraries/adb-scrcpy/esm/client.js:107:29) at async ScrcpyPageState.start [as onClick] (webpack-internal:///./src/components/scrcpy/state.tsx:229:32)

What Android version is it?

scrcpy server exited prematurely

Put a breakpoint at https://github.com/tango-adb/old-demo/blob/156d7f5f5f79d3999f685d291883dc125258ea73/packages/demo/src/components/scrcpy/state.tsx#L563 and inspect e.output to see server's output.

there may be a large number of mouse hover events on the interface that cause the lag

This is possible, but only with very poor network.

on the phone there are only touch events

Only some UI elements responds to hover move events. Android is mostly designed for touch after all.

I made some restrictions in src\components\scrcpy-all\scrcpy\video-container.tsx and solved this problem. Thank you very much for your patient help.
