HOME shortcut not working correctly on scrcpy v1.15

[zequip]

• I have read the FAQ.

• I have searched in existing issues.

• OS: windows 10

• scrcpy version: 1.15

• device model: Samsung galaxy j7

• Android version: Android 8.1.0

All desktop shortcuts stopped working on the latest scrcpy release (V1.15), only left and right click are recognized. If I rollback to V1.14 everything works as intended.

EDIT: remaining issue: only the HOME shortcut is sometimes broken #1643 (comment)

v1.15 now forwards Ctrl (and Shift) to the device, so the shortcut modifier (MOD) had to be changed. By default, it's Alt or Super.

See:

• https://github.com/Genymobile/scrcpy#shortcuts

#1642

[zequip]

I see, I read the changelog but I didn't realize the change. My bad...
I'm still having problems with middle click (home button). It works fine for a couple of seconds after startup, then it stops detecting it.

[rom1v]

Oh, you're not the only one 😕 #1598 (comment)

[rom1v]

Did you have the same problem on v1.14?

[zequip]

No problem on v1.14.

[rom1v]

That's very weird, I could not reproduce.

Could you add this log, please:

         return;

And when middle click fails, please post the line it prints in the console.

I'm sorry... Where should I add that?

[rom1v]

OK, here is a build:

• scrcpy.exe
  SHA256: 97437b46f4e540e9aa51ede53fdc130615af71de74668b85d3bd53850e9ec621

(replace it in your v1.15 release)

EDIT: run with scrcpy -Vdebug

[zequip]

This one didn't work from the start. I noticed it does work on the lockscreen but once the device is awake it stops detecting it (Alt-H isn't working either)

I'm sorry I can't be more helpful with logs and stuff, I'm not very experienced

[rom1v]

I'm sorry I can't be more helpful with logs and stuff

Oh, I put a debug log, so it is not printed by default (should have added an info log for simplicity).

Could you please run with scrcpy -Vdebug?

Press Windows+r, type cmd and press Enter.
In the terminal, type cd C:\Users\...(your path to scrcpy)...
Then scrcpy -Vdebug.

It should print logs when you press middle-click. Copy-paste them here.

[rom1v]

Nevermind, here is a build with an INFO log:

• scrcpy.exe
  SHA256: d79c39debe2306471f9f4625c77f2694c4b402380dc628cea3ea9e739a0cec7a

(replace it in your v1.15 release)

[rom1v]

once the device is awake it stops detecting it (Alt-H isn't working either)

When HOME stops working, what if you execute adb shell input keyevent HOME?

Press Windows+r, type cmd and press Enter.
In the terminal, type cd C:\Users\...(your path to scrcpy)... and press Enter.
Then type adb shell input keyevent HOME and press Enter.

[zequip]

the log says:

INFO: mouse button type=1025, which=0, button=2 (when I press middle-click)
INFO: mouse button type=1026, which=0, button=2 (when I release middle-click)

adb shell input keyevent HOME worked

[zequip]

Just in case I wasn't clear... the command worked at sending the home button, it didn't however fix the problem.

Also, the latest adb packaged with scrcpy fails at connecting wirelessly, is doesn't seem to be related to scrcpy because it works if I replace it with the previous version of adb.

[rom1v]

Oh, I think I found a possible cause for the broken HOME shortcut. Here is a fix: 8fb0192

• scrcpy.exe

Does it fix the problem for you? @zequip @AzureRaptor
