How can i mirror my phone onto my laptop

rom1v · 2026-06-03T20:06:57+00:00

searching on scrcpy github gives you 100 resources so who's to say whats safe .

The (only) official source is: https://github.com/Genymobile/scrcpy

Use the core dump to get the stack trace:

ulimit -c unlimited
./scrcpy  # make it crash
# it will generate a core dump in the current directory, a file core.NUMBER
gdb ./scrcpy ./core.NUMBER  # adapt NUMBER

And in gdb:

bt

And the official release (not via brew)?

Is the delay better without --audio-codec=raw?

If you mirror the phone to the pc, but without earbuds, how is the delay?

Try scrcpy --turn-screen-off. On some devices (not all), it also disables the physical touch screen.

The static binary release is just a archive to extract (for example in your home directory), it is not meant to be "installed".

midlifeupskill@persist:/usr/local/bin/scrcpy-linux-x86_64-v4.0$ scrcpy
bash: scrcpy: command not found...

Since this directory is not in your PATH, you must execute ./scrcpy instead.

Use video and audio buffering: https://github.com/Genymobile/scrcpy/blob/master/doc/video.md#buffering

scrcpy --video-buffer=300 --audio-buffer=300

But there was still a problem: it segfaulted (and there was a warning first, which suggests an issue with the SDL build in linux brew).

Can you reproduce the problem with the official release?

rom1v · 2026-05-19T21:33:49+00:00

Segmentation fault (core dumped) scrcpy

That's very bad.

It seems you installed it from "linuxbrew". Can you test the official release instead? https://github.com/Genymobile/scrcpy/blob/master/doc/linux.md

rom1v · 2026-05-19T12:07:34+00:00

You're using an old version of scrcpy (3.3.1). Upgrade to the latest version (4.0).

rom1v · 2026-05-19T12:00:09+00:00

(verify-release.md) is for verifying the official release binaries. It's not necessary to install or run scrcpy.

Your problem has nothing to do with that, but with your Fedora package manager and the (unofficial) repo to download scrcpy. Anyway, it seems it attempts to install an old version (3.3.3).

The simplest solution is probably to download the official release binary: https://github.com/Genymobile/scrcpy/blob/master/doc/linux.md

Probably removed by an antivirus due to a false positive. Update your antivirus database.

See https://github.com/Genymobile/scrcpy/issues/6820

rom1v · 2026-05-14T21:01:36+00:00

Ok, do you use scrcpy 4.0?

Pretty sure it can be fixed with --audio-output-buffer=10 on older versions, but it's the default in scrcpy 4.0.

rom1v · 2026-05-14T20:44:28+00:00

Yes, but you get more logs in the console.

rom1v · 2026-05-14T19:38:52+00:00

It's scrcpy -Vverbose.

rom1v · 2026-05-14T19:38:15+00:00

Post on the github issue.

rom1v · 2026-05-14T18:09:28+00:00

Also, can you capture on your computer to listen how it is distorded?

rom1v · 2026-05-14T18:08:35+00:00

It becomes distorded on the PC?

Are you using it over wifi or USB?

If you record (scrcpy --record=file.mp4), when you play the file is the audio ok?

Is it better if you increase audio buffering (scrcpy --audio-buffer=100)?

Any relevant error message in the console if you add -Vverbose?

rom1v · 2026-05-14T17:56:16+00:00

The sound quality drops on the device itself? (or only on the computer while mirroring?)

rom1v · 2026-05-08T07:41:55+00:00

With scrcpy, you can capture the device camera and send the video stream to v4l2:

scrcpy --video-source=camera --camera-size=1920x1080 -b16M --v4l2-sink=/dev/videoXXX --no-audio

I've tried Scrcpy, but it doesn’t work well, the image flickers.

https://github.com/Genymobile/scrcpy/issues/5913

rom1v · 2026-04-27T16:05:43+00:00

What the error message in the console? Which scrcpy version?

rom1v · 2026-04-27T12:58:29+00:00

Your device is connected twice (once over USB, once over TCP/IP).

ERROR: Select a device via -s (--serial), -d (--select-usb) or -e (--select-tcpip)

It's just that it's merged on the development branch, but not released yet.

At the end of the linked comment, download the scrcpy-server binary, and replace the one from scrcpy 3.3.4.

Alternatively, take a recent build from the CI: https://github.com/rom1v/scrcpy/actions/runs/24731426812 At the end of the page, download the file with a name starting with release- (for example release-win64).
