UnsatisfiedLinkError Can not find jnivideoInputLib.dll

[zchacker]

Hello, i have use FFmpeg in java to capture webcam and preview it, i use Dshow format.
when try to get webcams in FFmpeg, i did not find way to do that, but i use VideoInput library to get webcams name to pass it in this method.

int webcams = videoInput.listDevices();
String webcam_name[] =  new String[webcams];

int max = 0;	        
for (int i = 0; i < webcams ; i++) {
    	webcam_name[i] = videoInput.getDeviceName(i).getString();	        	
}
FFmpegFrameGrabber.createDefault("video="+webcam_name[0]);

the above code work very well in windows 8, but when i run it in windows 7 it show the he can not load "jnivideoInputLib.dll" file in this path

C:\Users\Compunet.javacpp\cache\room5.jar\org\bytedeco\javacpp\windows-x86_64\jnivideoInputLib.dll

and when i go the path i find the jnivideoInputLib.dll file
what is the problem and why javacv put dll files in this path instead of same jar resources

thanks

Could you please tell me what Dependency Walker says? https://github.com/bytedeco/javacpp-presets/wiki/Debugging-UnsatisfiedLinkError-on-Windows

it says the msvcp120.dll missing, and solve it, but is there a way to load webcams names using FFmpeg in javacv ?

Ah, yes, sorry about that. Fixed in the commit above.

It is possible to list devices with FFmpeg, yes, see issue #664 (comment), but we still need someone to integrate that functionality fo FFmpegFrameGrabber. If you would be interested in making a contribution, please let me know if you encounter any issues I can help with. Thank you for your interest!
