[MPlayer-users] How to control Mplayer from within another application?

[Carlos Lorenz]

Jason,

Thanks for your reply. I have tried hard but could not
understand completely how to use the bmovl filter.

Maybe you or someone else at this list could help me a little.

I made a FIFO and cat a PNG to it like this:

$ mkfifo /tmp/myfifo
$ cat mypng.png > /tmp/myfifo&

then I launched Mplayer to watch TV an see if the PNG image was on top
of video like this:

mplayer -tv driver=v4l:norm=ntsc:width=320:height=240 tv://4 -vf bmovl=0:0:/tmp/myfifo

Well Mplayer brings the TV image but no PNG overlay at all.

Thanks for any help

Carlos
