@Christywl could you please verify this first?

@rogerwang , my test results:
Linux: nwjs-sdk-0.20.3 and PepperFlash 24.0.0.221, flash works fine. But there is 'NOT SANDBOXED' in the console .
Windows: nwjs-sdk-0.20.3 and PepperFlash 24.0.0.221, flash doesn't work and it shows 'Couldn't load plugin'
Windows: nwjs-sdk-0.20.3 and PepperFlash 19.0.0.245, this issue reproduced, a console window flickered.

my package.json for Windows

{
  "name": "Test",
  "main": "http://www.adobe.com/software/flash/about",
  "chromium-args": "--ppapi-flash-path=C:\\nwjs\\PepperFlash\\24.0.0.221\\pepflashplayer.dll"
}

my package.json for Linux:

  "chromium-args": "--ppapi-flash-path=/home/***/.config/google-chrome/PepperFlash/24.0.0.221/libpepflashplayer.so"
}

@Christywl for the 2nd scenario under which flash doesn't work, could you please try with http://docs.nwjs.io/en/latest/For%20Users/Advanced/Use%20Flash%20Plugin/

[Christywl]

@rogerwang , I referred to the docs, put PepperFlash folder(including manifest.json/pepflashplayer.dll) under the nwjs-sdk-v0.20.3-win-x64, but 'Couldn't load plugin' still occurred. I checked with nw -url="chrome://plugins", and enabled the flash plugin. But it doesn't take effect.
cmd:
nw.exe --url=http://www.adobe.com/software/flash/about
or
nw.exe --url=http://www.adobe.com/software/flash/about --ppapi-flash-path=PepperFlash\pepflashplayer.dll

Environment:
Windows
nwjs-sdk-0.20.3
PepperFlash 24.0.0.221(built-in of Chrome)

I can confirm that this issue is still there in 0.14.7 LTS. @Christywl You can place the pepflashplayer.dll along with nw.exe and launch the application with these arguments --ppapi-flash-path=pepflashplayer.dll --ppapi-flash-version=<version>. In my case, a cmd window opens up and closes in a split second which says "not sandboxed". I hope you should be able to load the plugin on windows now.

[Christywl]

@RohitSharma27 , yes, as I mentioned in my first comment(the 3rd scenario), I could reproduce your issue with nwjs-sdk-0.20.3 and PepperFlash 19.0.0.245. But if I used the latest PepperFlash 24.0.0.221, I saw 'Couldn't load plugins'. I thought your PepperFlash version may be lower than 24.0.0.221.

[rogerwang]

@Christywl I just tried: latest 0.21 works with latest flash plugin 25 under windows.

[rogerwang]

The console window flicker is fixed in git and will be available in the next nightly build.

[rogerwang]

reopen since the patch need further review.

[rogerwang]

fixed again in git and will be available in the next nightly build.

The console window still flicker when using webview to load flash website.
nw.js version: 0.22.0
os version: windows 10
flashplayer version: 25.0.0.148

@Christywl, Warning!!!
Last picture Couldn't load plugin = It is seen wrong architecture of plugin! And make sure current 64 and 32 Bit version.

PS: It is not bug. And externalinterface always throw SecurityError :/

Hi guys!

I'm using NW.JS v30.5 and PepperFlash v29, all 32 bits, and I still have a flashing console (cmd.exe) window when using Flash content in my app! I got complains from users thinking it is a malware, so I would like to remove this windows.

The flashing console windows appears at the right moment I'm loading Flash content on the HTML page. Basically I do it at startup, but it can also be at another time

The flashing console windows lasts 100ms and don't display any message, or maybe it closes too fast to display anything.

I tried with several flash contents (SWF), some even without actionscript, the flashing window still appear. I also removed the "echo 'NOT SANDBOXED'" in pepflashplayer.dll, no effect too.

Please help, thanks in advanced
Josh

The appearance of command line went away for me when not using SDK release. Oops, this is wrong. Computer was faster than my eyes
