[dhanasekaran.sm]

Hi Everyone:

I want to overlay image on my webcam video streaming and i followed some of the steps:

In Terminal 1 i executed:
1. mkfifo tfifo
2. mplayer -vf bmovl=0:0:tfifo tv://
After this command i can able to see the webcam stream.,


in my second Terminal 2 i hv executed:
1. echo "RGBA32 200 200 0 0 0 1"; cat overlay.rgba >tfifo

after executing this command I got a error message on the terminal 1 : "vf_bmovl: Unknown command: ''. Ignoring." at the final it shows "Mplayer Crashes".

This is very importance for my career please somebody help me to solve this problem.

Thanks in Advance!
