Fails with more than one device or emulator.. even if theres only one device

[cswl]

adb devices

Thank you for your report.

error: more than one device/emulator
ERROR: "adb reverse" returned with value 1

This is "expected" over TCP, that's why a fallback to adb forward has been implemented. See #5.

WARN: 'adb reverse' failed, fallback to 'adb forward'

If after that scrcpy stops without displaying the device, the number of connection attempts for adb forward is probably too low (see discussion). It has been increased on master (not released yet).

[rom1v]

Could you try with v1.2, please?

[pundoo]

@rom1v Yes, it works with v1.2, but the error (impt?) still shows up.

[rom1v]

but the error (impt?) still shows up.

That's expected (see #5). 👍

Same error with v1.6 here

scrcpy -v
scrcpy 1.6

dependencies:
 - SDL 2.0.8
 - libavcodec 58.18.100
 - libavformat 58.12.100
 - libavutil 56.14.100

[rom1v]

@pablitok This "error" is expected over TCPIP (and harmless, since there is a fallback). Do you use it over wifi?

[pablitok]

Sorry, I misunderstand that the expected error was the one about the fallback, not the one about multiple devices. Yeah, I use it over wifi Thanks!

[rom1v]

@pablitok So it works? (if it does not, please paste the whole scrcpy output)

[pablitok]

yeah, it works,!

Hey @rom1v, I'm hitting this issue too on 1.10:

 chag0709  Carstens-MacBook  ~  $  scrcpy -t
2019-09-13 13:16:43.146 scrcpy[29062:450094] INFO: scrcpy 1.10 <https://github.com/Genymobile/scrcpy>

I've got an emulator running and a device.

[rom1v]

I've got an emulator running and a device.

Then use scrcpy -s SERIAL, with the serial as printed by adb devices.

[aminukano585]

@rom1v I really need your help on this, I've tried all the workarounds but it still fails.

Here is my scrcpy version:

$ scrcpy -v
scrcpy 1.11

dependencies:
 - SDL 2.0.8
 - libavcodec 57.107.100
 - libavformat 57.83.100
 - libavutil 55.78.100

Here is my device, you can see it's just one:

$ adb devices
List of devices attached
192.168.43.1:5555	device

But after runniny scrcpy command, the error persists

$ scrcpy
INFO: scrcpy 1.11 <https://github.com/Genymobile/scrcpy>
/usr/local/share/scrcpy/scrcpy-server:...shed. 0.6 MB/s (25454 bytes in 0.038s)

[rom1v]

adb: error: more than one device/emulator
ERROR: "adb reverse" returned with value 1
```

This is an expected error message (see #5), but then it fallbacks to adb forward, so this is not the problem.

Aborted

Probably #944. Try v1.10 or dev branch instead.
Could also be #268 (see #956).

[aminukano585]

Thanks a lot @rom1v it now works with v1.10..

But there's one little issue, the device appears upside down :)

[rom1v]

@aminukano585 Please open a new issue for that, with more details (device, android version, does it always happen, screenshot...). Thank you.

[aminukano585]

Thanks, @rom1v, I just created #972 to this effect.
