Hello, I am a truly beginner, I recently installed Mencoder, I need to set
a logo onto an .AVI file.
I read many examples but I couldn't then work properly. I tryed what is
said here

>From console I did this:

logo = ...

mkfifo tfifo
# Convert logo to RGBA.
convert $logo tlogo.rgba

# Copy logo to fifo.(echo "RGBA32 $logo_width $logo_height 0 0 0 1" ;
cat tlogo.rgba ) >tfifo &

but it got frozen, I need to abort the command.

 # Convert input video with overlay from fifo.
mencoder -oac pcm -ovc raw -vf bmovl=0:0:tfifo -o $output_video $input_video

Thanks in advance for any help. Regards
