I use avconv to encode a rtmp stream.
I have a PNG overlay over the video.
I would like to, each time the png picture is updated, the overlay is updated to.
Si I try to add:
-f image2 -loop 1 -i /score.png
but I still have to restart the stream to refresh the overlay picture
avconv -f video4linux2 -r 25 -i /dev/video0 -f image2 -loop 1 -i /score.png -filter_complex "overlay=20:160" -f flv rtmp://localhost/live/
avconv options are the same than ffmpeg ? (https://stackoverflow.com/questions/42735121/ffmpeg-continuously-stream-refreshing-image-to-rtmp)
Ideas ?
Thx
