Re: Re: Overlaying an image on a live stream

[Jan Spurný]

Hi,

there are two options:

A) use "freezeimage" element after pngdec,

B)  instead of

 filesrc location=graph.png

use multifilesrc with caps

 multifilesrc location=graph.png caps="image/png,framerate=(fraction)25/1

(of course change to your framerate)

sincerely,
Jan Spurny
