Mosaic Not Displaying (win7-64 vlc-2.1.5)

[angrycamel]

I am trying to get a 2x2 grid of identical brand webcams to display using mosaic but I'm not having any luck. I'm hoping someone here can help me out.

What I see when I run the command is two windows open. One is the console window and the other is a VLC gui window with no video playing (showing the default logo on black background).

During this time the first of the 4 webcam's activity LED starts blinking, then after a few seconds all 4 webcam LEDs start blinking then go solid after a couple more seconds. Eventually the mosaic video never plays then the console and gui windows close themselves. Next time I start VLC it says that it crashed and asks me to send feedback (which I do).

Any help is appreciated. I am not a VLC expert but I have poured over the many forum posts about it that are applicable to version 2+ (no more "fake" so a lot of older examples are obsolete).

I am using Windows 7 64 bit and version 2.1.5 of VLC.

Hi all,

I am using VLC 2.2.1 and tried to use VLC but i am not seeing any grid. Instead one big window opens and i do not see any video playing.
I don't see any error message and also i verified that video decoder is working fine but i do not see any video being played.
I have tried changing the version to 2.1.5 also and found no difference.
Can anyone help me understand i have made any mistake. My vlc script is below:
