[FFmpeg-user] question : Inserting text and multi Graphic card

[bino oetomo]

Dear All ..

Let's say I have an AV capture card.
How to use FFMPEG to play live capture but with inserting some "user 
defined news ticker (running text)" on the top part of the screen ?

Also ... if I have multi AV capture card and multi graphic card , can I 
run multi instance of FFMPEG with each instance for a pair of in-out 
direction ?

Sincerely
