After review on FFMPEG website you gave me.
I need to over very (2) stream to (1) stream and create stream (3)
According to achieve 2×2 mosaic stream I have to overlay
(1) + (2) -> 3
(4) + (5) -> 6
then
(3) + (6) -> finial stream (7)
Correct?
Could you point me to config command to position overlay video (top left 320×240, top right 320×240 etc)
Thank you
