scrcpy (Android desktop emulator)

#1 Post by Midas » Sat Jun 20, 2020 2:29 pm

I have tested scrcpy (https://github.com/Genymobile/scrcpy) both in Windows and in Linux with different results; when first ran, my first result was a console error In both platforms like this:

Code: Select all

INFO: scrcpy 1.14 <https://github.com/Genymobile/scrcpy>
adb: error: failed to get feature set: no devices/emulators found
ERROR: "adb push" returned with value 1
Press any key to continue...
In Linux (Ubuntu Mate 20.04) the error went away once I changed the USB connection from "Charge the device" to "Transfer files"; in Windows, although it enabled browsing phone files, the same action got no results -- i.e., an interactive display of the phone screen in my desktop.

Anyway, when it works scrcpy can be really handy for anyone with an Android phone (v5.0 or newer), so here's the gist of it...

This application provides display and control of Android devices connected on USB (or over TCP/IP). It does not require any root access. It works on GNU/Linux, Windows and macOS.

Bear in mind that scrcpy isn't entirely stealth because it needs to have a working USB driver. Other than that, I couldn't find any traces of it in my system.

Windows tutorials for scrcpy can be found at: Download scrcpy latest release (currently v1.14) from https://github.com/Genymobile/scrcpy/releases.

I'm not sure I'd class this as an emulator, more like an easy remote-desktop program.

Anyway, about a year ago, I had a reasonably new tablet computer with a cracked screen that would have been *amazing* to use with this software. I wish I'd known about it ...

Uses

As mentioned above, this could breathe new life to an android device that's either old or damaged (or both), though it would require an at least somewhat usable screen to enable the Developer Mode. I can see a lot of ways it could help including:

Apps
  • Get access to Android-only apps in a native environment (run it right off your phone)
  • Use of any of dozens of popular Electron applications without sacrificing a gig of RAM on your computer
  • Avoiding security issues with installing some software programs on your computer (e.g. use a BitTorrent client at work)
  • Play games on your computer (puzzles, chess, etc. should all work fine, not sure about very visual games)
Convenience
  • Keeping your phone visible without taking up space on your desk
  • Setup the camera on a tripod or for use in product photography without having to touch the screen (and maybe mess up the position) everytime you want to make a change

Testing notes

I didn't connect my Android device to the Internet *at any point* in the test below, so you can use this with phones that may not have all the latest security patches (so long as it's newer than API 21 (Android 5.0 / Lollipop).

Clipboard text is supported between both devices so you can copy and paste into and from your scrcpy window.

I had a fairly new Galaxy Tab and it required both enabling Developer Mode and USB Debugging (as discussed on the webpage). Beyond that, usage was very intuitive. Even though I get into some detailed functions below, that shouldn't scare anyone who avoids command-line interfaces from giving this a try.

My launch arguments

Code: Select all

scrcpy.exe --turn-screen-off --window-width 600 --window-height 960 --bit-rate 2M --rotation 0 --stay-awake
The settings above turn the screen off, sets the to my Galaxy Tab A (found with a breif web search), reduces the refresh rate just because my needs are minimal (it looks fine), turns off rotation, and the device doesn't go to sleep.

The test screen is actually 800 x 1280 but my screen isn't that tall and it looks fine at 75% size.


Untested
  • Full screen video or intensive graphical apps (e.g. racing games)
  • Multi-touch operations (not sure it's possible)
  • Copy/paste images (like I did with text)
---

Would love to see a graphical front-end for the program to launch with common options. Would see a wider usage base and an amazingly useful and benefitial program to breathe new life into old or damaged phones and tablets.

Some good questions raised there around CLI vs. GUI and you're right that there's some overlap. For the site's purposes, some people are always going to be reluctant to touch anything that requires a command prompt. scrcpy is definitely right at the edge of the dilema.

Excellent, thanks.

The weird part is I pictured in my head what the interface would look like and whomever came up with this program thinks a lot like me.

My thoughts, precisely. :neutral_face:

So, I will respond there not to fragment the discussion (also because scrcpy is just an example. This is really a discussion about what to include in the database).

This tool forwards audio from an Android 10 device to the computer. It does not require any root access. It works on GNU/Linux, Windows and macOS.

The purpose is to enable audio forwarding while mirroring with scrcpy. However, it can be used independently.

Requirements
  • The Android device requires at least Android 10.
  • VLC must be installed on the computer.

This just keeps getting better. This thread has made me start thinking about trying to find a used Android device and use it for various extras. Now maybe that includes a music player.

Cool. :sunglasses:

Incidentally, I'm in the process of trying to replace my aging Axon 7 with a mint new Poco X3, while struggling to decouple vanilla Android from the overbearing GApps framework -- something that could take me months... :confused:

When (and if) I manage that, I plan to convert the Axon to /e/ (https://e.foundation/) and I'll surely have a lot more uses for such tools.

Are you aware of microG, an independent open source reimplementation of GApps? Many custom ROMs allow you to use microG instead of real GApps.

Yes, I am -- and of Nanodroid, too. :nerd:

I first learned of it through the Vanced Youtube client (https://vanced.app/).

I was really close to have it all setup last July -- in a Redmi Note 8 I got back in January, but had to pass the device to a relative in need...
