play webcam stream in mplayer on windows.

[arthurm]

I'm trying to play a webcam stream using mplayer. I have made a TKinter interface in python, but I couldnt find any way to embed a video file in it. So I created a button that, when clicked, plays the video stream in a second screen. For this I chose MPlayer. The command I tried:

mplayer -cache 10000 http://192.168.2.2:8080/?action=stream

it gave this error;

I had to press "q" to cancel those "cache empty" messages, and then the screen with the video screen popped up for a split second. Increasing the cache doesn't help.

I there a way to run this command and just get a screen with the stream playing?
