[MEncoder-users] insert an image - overlay image

[Rossana Guerra]

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
http://www.linuxjournal.com/content/overlay-images-video-using-mplayer-and-mencoder

>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
