Is the device a Meizu?

If yes: #888 (comment)

zer0de · 2019-11-17T20:58:19Z

No the device is a Amazon FireTV Stick Rev.1

rom1v · 2019-11-17T20:59:24Z

Could you please still test the jar from #888 (comment)?

If this does not work, please paste the output of adb logcat when you start scrcpy.

zer0de · 2019-11-17T21:01:32Z

adb.log
yes i do, and then i make an edit.

thx

The Log doesnt end...^^

Hmm, so the device does not return any display info.

Let's use a fake one not to crash:

(replace it in your v1.10 directory)

Does it work?

(if it "works", you should see the top-left 800x600 part of the screen)

and again... :-(

rom1v · 2019-11-17T22:01:09Z

OK, it seems the device does not behave like a "normal" Android device:

we cannot retrieve display information
there is no keymap (so text injection will not work)

Maybe we could adapt to avoid crashing and make it "work" in a degraded way, but I'm not even sure. Anyway, it would require investigations with the device, so if someone have the device and is comfortable in Java to investigate… your help is welcome.

rom1v · 2019-11-17T22:03:27Z

INFO: Initial texture: 1920x1080

I'm surprised that you get this, given that retrieving the display info crashes the server: #932 (comment)

zer0de · 2019-11-17T22:08:17Z

ok, thanks a lot. "IF" I have a solution i will be edit or leave a comment

sry, typo mistake

rom1v · 2019-11-18T05:59:33Z

I have a solution

❓

sweenwolf · 2019-12-03T13:03:49Z

Scrcpy works fine on Firestick 4K, it should also work fine on regular firestick.

ManuLinares · 2020-12-09T15:24:57Z

Still not working on a Firestick V1

ManuLinares · 2022-01-18T23:57:01Z

Bump, as it still not working for Firestick v1,

#1916

I'm willing to test, debug, etc...
