Scrcpy: 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
Invalid return value 0 for stream protocol

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 (https://github.com/Genymobile/scrcpy/commit/2876463d394c3bc4dc239a605e65ebab75598353).

it does not say how to close scrcpy

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