Some error message when closing window in windows

[npes87184]

Hi,

When I close window in windows, it will show:

Invalid return value 0 for stream protocol
Invalid return value 0 for stream protocol

There may be some problem in closing resource.

btw, scrcpy works well on windows.

PS C:\Users\YuChenLin\Downloads\scrcpy-win64> .\scrcpy.exe
scrcpy-server.jar: 1 file pushed.
INFO: Initial texture: 1080x2280

PS C:\Users\YuChenLin\Downloads\scrcpy-win64> .\scrcpy.exe --version
scrcpy v1.5

Thanks,

Thank you. There is this warning for a long time (since this FFmpeg commit), I never investigated before.

So now, I did, and it's fixed on master.

Sorry to report the same problem on Windows 10 Home 10.0.17134 Build 17134, x64-based PC w/ scrcpy-win64-v1.5.zip when using the wireless feature (over TCP/IP) and closing scrcpy using the X above the mirrored display of a Galaxy S5 SM-G900M running haggertk's Unofficial S5 klte LineageOS 16.0 build 2018-12-10.

BTW it does not say how to close scrcpy in https://github.com/Genymobile/scrcpy > README.md.

Or is it better with a command-line argument? Which one would that be?

Edit: Using scrcpy via USB, I got the same "Invalid return value 0 for stream protocol" after closing it:

@curiousrom it is fixed in master so the fix will be included in the next release (2876463).

it does not say how to close scrcpy

Just close the window. You can even unplug the cable or disconnect adb.
