High Latency

[GodDagon]

I am using scrcpy v1.18 in windows and Android 10.
I am getting a high delay in this build, in previous build it was good but in this build I am not able to use scrcpy sir to high latency.

Probably not related to a difference with older scrcpy version. Could you try an older version now and confirm that it works fine?

If not, try rebooting your device and/or computer.

Ok I'll try and tell you.

I tried both v1.17 and v1.18 and got a delay of 1-2 sec in v1.17 and it's 4-5 sec in v1.18.

1 or 2 seconds of delay is totally broken. You should never get more than 100ms (which is already bad).

You probably have an issue with your graphics drivers.

Is the stream just delayed, or also stuttering/low fps?

What if you record then play the file?

scrcpy --record file.mp4

I just play a YouTube video to check the delay and when it's 12 sec on my mobile it's 8 sec on my pc.

Is it over USB?

Here is the latency you should expect: https://www.youtube.com/watch?v=LLpcLB0QlJg

This was captured with scrcpy v1.1 in 2018.

The latency has still been improved since then, by #646. And newer devices also have a lower latency (their hardware encoder is more efficient).

[GodDagon]

No, it's not. It's not working well now. Can I send you video.

I am also facing the same issue. huge latency (about 10 secs on usb and 13 secs on tcpip) when I mirror at 1080p on windows 11, but latency lowers at lower resolutions e.g. 480p but the quality is too low.
I have a secondary laptop with lesser specs running on Ubuntu LTS 22.0.4 and everything works really smooth there even at higher resolutions.

edit: It is not just a delay, it is also skipping frames.
Could it be the renderer? Because touch/key response still works with low latency even when the screen render is almost 10 secs behind(I hope you get it).
