Features implemented in a fork

[rom1v]

Here is a specific thread for https://github.com/Genymobile/scrcpy/issues/495#issuecomment-517322589 (@Lurker00):

Currently I've forked this project, and merged all my changes into the official 1.9 version. It is there. I only have Android 8.1 devices, so I'm not sure that all my changes will work for all. It requires additional app (my dirty build of ADBKeyBoard) to type any language and to sync device's orientation by PC. In general, I'm not sure should I try a pull request... But you may build both projects yourself and give it a try...

The full list of my changes (sorry for misuse this thread!): User visible changes:

• 10-fingers multitouch support.
• Any charset input support with an aid of ADBKeyBoard.
• Quit command (Ctrl-Q)
• Ctrl-Shift-O turns device screen on.
• Connection timeout detector from the device side (useful with connection over wireless network).
• Screen density and screen size can be set on the device during the session.
• "Tablet mode": dim device screen, synchronize device screen orientation with PC (requires additional service on the device).

Internals:

• The server "forks" itself for full life cycle control (adb may kill it instead preventing required cleanup).
• Full cleanup at exit.
• Expandable parameters to the server applet, allowing compatibility between versions.
• Java NIO to simplify network I/O and not be limited to Unix sockets.
• Different connection type: direct connect to the device instead of "adb forward".
• Commands: actions with no parameters

Hi,

Thank you for sharing all your work. :+1: You implemented a lot of things in your corner!

In general, I'm not sure should I try a pull request

When features are "general" enough and would benefit everyone, yes you should propose to merge them (one PR per feature based on the current dev branch) :) (and this would minimize the amount of work for you to keep your fork up to date :wink:)

• 10-fingers multitouch support.

This is definitely a feature to merge (#22). I investigated locally, especially to support pinch-to-zoom (#24) with Shift+click or something. Both features should share a lot of code.

• Any charset input support with an aid of ADBKeyBoard.

(didn't look yet, also see https://github.com/Genymobile/scrcpy/issues/431#issuecomment-471245573)

• Quit command (Ctrl-Q)

Is it necessary? (every system already has it own shortcut, typically Alt+F4, don't they?)

• Ctrl-Shift-O turns device screen on.

I disabled a similar feature on purpose before the last release: 8c8649cfcd710859ce18eab557ed2af8cedb9a42. Is it the same?

• "Tablet mode": dim device screen, synchronize device screen orientation with PC (requires additional service on the device).

Could you explain what it does and what is the use case?

• The server "forks" itself for full life cycle control (adb may kill it instead preventing required cleanup).
• Full cleanup at exit.

Did you implemented additional cleanup on the server side on exit? What is the required cleanup?

• Expandable parameters to the server applet, allowing compatibility between versions.

(the client installs its associated server, so using an old server with a new client is not a goal, and it would require far more than backward compatibility of command-line arguments)

• Java NIO to simplify network I/O and not be limited to UNIX sockets.

Indeed, I removed (before the first release) the NIO usage on this specific part to use Unix sockets on the device side (because we don't need TCP here), and NIO/channels does not support UNIX sockets.

Why do you need a TCP socket on the device side? (oh, the answer is probably in the next point)

• Different connection type: direct connect to the device instead of "adb forward".

IIUC, you start the server then connect over TCP directly? The problem I see here is that anyone on your network can connect (with the right timing) to your device without any authentication. If you use adb forward, it requires that adb is authorized.

https://github.com/Lurker00/scrcpy/commit/32b0fb045ad9bab2a4076ff8e32b9b7e85fdde81?full#diff-2b1a6238bf364c50a82e0f738e186e23R40-R41

My understanding is that this flag only impacts the "sender":

   TCP_NODELAY
          If set, disable the Nagle algorithm.  This means  that  segments
          are  always  sent  as  soon as possible, even if there is only a
          small amount of data.  When not  set,  data  is  buffered  until
          there  is  a sufficient amount to send out, thereby avoiding the
          frequent sending of small packets, which results  in  poor  uti‐
          lization of the network.

The purpose here is to send the control messages earlier?

https://github.com/Lurker00/scrcpy/commit/32b0fb045ad9bab2a4076ff8e32b9b7e85fdde81?full#diff-2b1a6238bf364c50a82e0f738e186e23R43-R44 https://github.com/Lurker00/scrcpy/commit/32b0fb045ad9bab2a4076ff8e32b9b7e85fdde81?full#diff-bdecf0d14db2a1fac70f95f687544d01R101

I just set these flags locally, I still receive packets of 4096 bytes. Probably due to the adb tunnel (adb reverse).

one PR per feature based

It's a huge work! I was very limited in time: tomorrow going to vacations for full August to the place with very poor Internet, and I need this my scrcpy mod fully working. Now I have to separate different parts... Definitely not now :(

Ctrl-Q: Is it necessary?

My notebook has no F-keys. Alt-Fn-4 didn't work well with 1.8 on the previous (already died!) notebook for a reason... Now I see it works, but Ctrl-Q still works better for me.

Ctrl-Shift-O: I disabled a similar feature on purpose

I see... Yes, sometimes it works weird, but it was handy for tests - to save power, but sometimes to look to the phone. I don't insist :)

Tablet mode: Could you explain

This is my primary goal, and what I can't live without! I have small phone (Unihertz Atom, 2.45" 240x432 screen), and a small convertible notebook (One Netbook Mix 3, 8.4" 2560x1600 screen). With my mod of scrcpy, I connect Atom to Mix 3 in full screen mode, forcing high resolution and low DPI on the phone, and I end up with powerful Android tablet! Notebook rotation forces Android screen rotation (even apps that, in general, refuse landscape, work in landscape), screen is dimmed to save power. Lots of apps (banking, messengers with video and pics) require Android, but work better on big screens.

On the other hand, a person with very high resolution device and lower resolution notebook/PC may want to decrease device's screen resolution, and decrease density to force tablet mode of Android.

What is the required cleanup?

• Restore screen size and density.
• Restore screen brightness.
• Restore the original IME and disable ADBKeyBoard (if it was disabled).
• Put the device into sleep (because in my use it is in the belt pouch). The first two items are essential: the device is quite useless with minimum brightness and tiny controls. That's why I've implemented "PING": connection over WiFi can be lost, and it is required the server to stop and quit with full cleanup by itself.

  Args handling: using an old server with a new client is not a goal

I found my approach of passing parameters is more convenient during development, and more easy to maintain. No magic numbers, all in all!

NIO/channels does not support UNIX sockets

NIO does implement WritableByteChannel directly. In fact, I've deleted your IO.java, because channels work with ByteBuffer directly. The resulting code is shorter and, I think, faster, even via Unix sockets.

Why do you need a TCP socket on the device side?

To eliminate adb as the proxy via WiFi. With NIO and TCP I have direct connection with full control. I even disconnect adb from the device in such a use.

The problem I see here is that anyone on your network can connect (with the right timing)

The server listens only for two connections (video and control), then stops listening. The "right timing" is a few milliseconds during the startup. Moreover, the listening port is assigned by the client side, and can be changed from the command line. I see no a problem here.

But in my use, I set up the device as the WiFi access point, connect notebook to it, and nobody else exists in this private network. No problems whatsoever.

TCP_NODELAY: My understanding is that this flag only impacts the "sender"

Yes. It works for direct TCP connection over WiFi, to minimize delays between touch, mouse, keyboard events. Touch and mouse events are assigned timestamps on the device, and a touch may become long touch, or vice versa.

Probably due to the adb tunnel

That's why I eliminated adb as the proxy!

I just have committed a number of more changes that I forgot yesterday:

• command line option for device screen size;
• experimental ToS for sockets (in my tests, it works better in the WiFi-noisy environment);
• a long comment regarding touch events.

For the remaining hours (before I go to vacations), I plan to write a public description and release a binary build for those who wants to try. But this is also my last day at work before long vacations...

[rom1v]

Thank you for your answer.

It's a huge work! I was very limited in time: tomorrow going to vacations for full August to the place with very poor Internet, and I need this my scrcpy mod fully working. Now I have to separate different parts... Definitely not now :(

OK, I understand. Could I take parts of your code if I need to? (probably not now too :wink:)

Executing cleanup even if adb is killed can indeed be interesting (for example for issues #96 #101 #181). I always considered that a wrapper script was sufficient for this "advanced usage", but it is better if it always cleanup. I keep that in mind. :+1:

Btw, maybe it is possible to use nohup instead of forking (but I'm not sure it is available on all devices). Alternatively, a solution could be to set a signal handler on SIGHUP, but it's probably not possible directly from Java. But starting a new process is a good solution.

NIO does implement WritableByteChannel directly.

Not for UNIX sockets.

In fact, I've deleted your IO.java, because channels work with ByteBuffer directly. The resulting code is shorter and, I think, faster, even via Unix sockets.

It seems you either don't use channels for UNIX sockets or add just add a wrapper to the OutputStream.

Touch and mouse events are assigned timestamps on the device, and a touch may become long touch, or vice versa.

Oh, that's bad. (TBH I never use scrcpy over wifi)

[Lurker00]

Could I take parts of your code if I need to?

Of course! If you save me some time merging all the useful changes yourself, it would be great! That's what I've published my changes for - to be used by other developers, just like I've used your product.

just add a wrapper to the OutputStream

Yes: Channels.newChannel(localVideoSocket.getOutputStream());

I never use scrcpy over wifi

I found it quite useful in a long trip in a bus or train: phone in the belt pouch, little notebook in hands, I can switch between Android and Windows, and no wires. Small lags are acceptable.

For me, scrcpy is the app that I use several times per day. Clipboard transfer from Android to Windows in 1.9 was the feature pushed me to perform the merge. Did I thank you? I will! :)

[Lurker00]

Published Windows 64-bit package for those who want to test it.

[Daniel-Brum]

If I follow the default build instructions, can I make this fork work on Linux?

[Lurker00]

I think it should work. Build it per original instruction. You may extract ADBKeyBoard's apk file from my Windows release package.

I never tried it under native Linux myself, but it worked somehow with Ubuntu 18.04 LTS from WLS and an X-server under Windows.

You may try and let me know :)

[Daniel-Brum]

I tried yesterday and couldn't get it to work. But since I don't recall ever building anything, I'm probably doing something wrong. Building using the prebuilt server goes perfectly until the ninja command, when I try to install or run things start going wrong (when installing I get

[Lurker00]

You may use prebuild server from my Windows package as well.

[Daniel-Brum]

I have Android 6.0.1.

[Lurker00]

I just published a new release: https://github.com/Lurker00/scrcpy/releases/latest The ClassNotFoundException should gone. You may try the new server build, and to build the client from the updated sources.

But I have no pure Android 6 device in hands, only with MIUI under which almost everything does not work silently.

[Daniel-Brum]

I'm still unable to sudo ninja install, with the same warnings from before. But I could run scrcpy just fine. Thanks a lot for helping me! (Editted because I sent the first line without typing the rest accidentally)

Edit 2: The warnings didn't actually get in the way or anything, it looks like the application is installed correctly. Sorry for my hasty complain, and thank you again!

[rom1v]

with the same warnings from before.

These are just warnings, not errors. See https://github.com/Genymobile/scrcpy/issues/458#issuecomment-473711107

[Daniel-Brum]

Oh, I see. Dunno why, but I simply assumed the program wouldn't be installed properly because of that, I should've searched about it first. I'm sorry and thank you.

[codycodes]

Just wanted to give my experience here; @rom1v I attempted to run your changes from the latest release, and while I get a message stating scrcpy started: processid1234? (not sure if it's a process id or not), the window doesn't open like it does when running scrcpy from Genymobile. Is there something additional I'm missing to be able to see scrcpy with your fork? Also wanted to put in a +1 for tablet mode as it'd dramatically help my workflow:

1. plug in android phone
2. android phone will not sleep with Tasker task
3. screen on android phone goes dark but is visible on PC
4. can use surface pro in multiple orientations with android phone switching automagically
5. when unplugging, android phone screen turns back on and potentially reverts orientation

[Lurker00]

@codycodes, Sorry, I overlooked an additional thread introduced in 1.9, which caused malfunction sometimes. I've comitted the fix. Here is an update: https://github.com/Lurker00/scrcpy/releases/latest

Note: you must use both server and client binaries from my fork! The typical session is like this:

[server] INFO: scrcpy is forking: 14191
[server] INFO: scrcpy forked
[server] INFO: scrcpy started: 14200
[server] INFO: DeviceControl started
[server] INFO: Connected to desktop
[server] INFO: bitRate: 8000000 frameRate: 60 iFrameInterval: 5 repeatFrameDelay: 6
[server] INFO: Command QUIT received
[server] INFO: Controller stopped

where 14191 is a PID of the server launched from PC via adb, and 14200 is the secondary copy of the server, which actually performs the job in my fork.

Please note that while this build works for me, I have no abilities to perform thorough tests with different devices, but I try to resolve reported problems.

I use the following command line: scrcpy-noconsole.exe --density 240 --fullscreen --tablet-mode --ime -s ATOMHZ0000005703 --render-expired-frames Of course, the density and serial is up to you. It works for me as you described, but I don't use Tasker.

[Pixelstudio]

I have the same problem, starting your latest release version i only get this in my console : [server] INFO: scrcpy is forking: 22392 [server] INFO: scrcpy forked [server] INFO: scrcpy started: 22402

Then nothing, no window opens... Any idea?

[Lurker00]

@Pixelstudio , is it L2 build for Windows, or a custom build for Linux (then which revision)? Which Android version do you have? Is it pure stock Android or what? Currently I can only answer that it works for me flawlessly ;)

[codycodes]

Also tested but not working here. I'm on a Surface Pro so hoping to be able to use these features at some point. I have the same output, which is nothing after the info logs. Thanks for your work and help!

@codycodes , again:

• No explicit statement which build did you try.
• No Android version info.
• No statement that the official scrcpy works somehow (meaning, it is not a general problem).

You (all who experience problem with my build) may also type adb logcat -d > logcat.txt

open logcat.txt in a text editor and search for possible exception stack traces for scrcpy, to provide a clue. I'd glad to make this fork to work for more people, but I need details about the problems.

[Pixelstudio]

Here are some details (i cannot find something that would cause an error)...

I'm using your latest win64 build "scrcpy-win64-0.9-L2" The latest version of the official scrcpy works as expected, without any problems I'm testing on a win10 pc, my phone is an Pixel 2 XL, Android version 9, build number PQ3A.190801.002

here is part of the logcat:

[Lurker00]

Sorry, but this dump gives no a clue :( I just published v1.9L3. It has no a fix for you, but please try it - it should provide more info to the console in case of problems. I've also enabled Issues for my fork, so we may continue there.

I tested this version, same problem. Also nothing in the logcat

[Lurker00]

@Pixelstudio , I thought it would be more information in the Windows console, right after [server] INFO: scrcpy started: ... line. Is there something new?

[Pixelstudio]

Nope nothing in the console

[Lurker00]

I'll have to find Android 9 device or install a simulator to work it out, but this may happen not earlier than September.

[Lurker00]

1.10-L0 tested against Android 5-10 emulators (before merge with 1.10, if it matters). Includes recent changes made after the official 1.10 build (up to da5b0ec).

[parkerlreed]

I am so excited to report that the multitouch also works great with the KMS/DRM support. Don't even need X or Wayland running!

[parkerlreed]

How is the IME implemented? (Along with wireless mode)

I compiled the fork along with compiling the server jar in the same step. I don't see anything extra on the phone when connecting.

[parkerlreed]

Oh I see now. I didn't realize ADBKeyboard was its own aplication.

[parkerlreed]

Tested wireless here (killing adb after launch)

Works well (for wireless)

Only note is that after exit: it still tried to run adb disconnect (I assume because it wasn't aware I killed manually)

[Lurker00]

@parkerlreed, thank you for the report! My build of ADBKeyBoard (included into Windows packages) has an additional service to force Android screen rotation.

it still tried to run adb disconnect

Actually, when it connects directly (with -s address:port parameter), it connects adb by itself, and disconnects adb after reaching the server, and calls redundant disconnect at the end. It does not harm.

[parkerlreed]

@Lurker00 If I kill the adb wifi from the phone side, the program exits. Does it still rely on that running?

[Lurker00]

I can't reproduce it: my phone is not rooted. I may only guess that killing adbd also kills its child processes. adbd with direct connection is only used to proxy server's stdout. For Windows, there is -noconsole build that outputs nothing from the server.

[rom1v]

I started to implement multitouch, but I have no touch screen, so I cannot test.

If someone want to test (and help to fix if it does not work), I pushed a branch: finger.

@Lurker00 you could probably avoid your timestamps stuff to avoid duplicated events: 907e55a66b750b234f0e1843a98f5cbaababad6f

[rom1v]

Seems to work now: finger.5.

Please give me your feedbacks. I will rewrite the commits properly when I have time.

[parkerlreed]

@rom1v :+1:

Added benefit of not crashing scrcpy when show pointer location is enabled :)

[sandriaas]

thank you so much for this form!! love it!! btw is it possible to use desktop mode function on android q to be used in scrcpy?

[Lurker00]

you could probably avoid your timestamps stuff to avoid duplicated events: 907e55a

Thanks for finding! Yes, it works, but I've also added the same check into input_manager_process_mouse_button().

[rom1v]

(just for info, multitouch is now implemented on dev and will be in the next release)

[parkerlreed]

thank you so much for this form!! love it!! btw is it possible to use desktop mode function on android q to be used in scrcpy?

This would be fantastic. If you want to spin up an issue for it, I'd be happy to chime in and help test any possible implementations.

[Lurker00]

@andrizmitnick, @parkerlreed: don't know about desktop mode, but, from my experience, Android switches from phone to tablet mode with lower density. You may try --density command line option in my fork to see if it works for you.

[parkerlreed]

@Lurker00 That was waaaay back on 4.4.2 and earlier. This new desktop mode is activated somehow and gives you floating windows and such.

https://www.androidauthority.com/android-q-desktop-mode-demo-991055/

Granted it not in that form yet but there's some basic things in place
