watermark or txt writing on the stream.

[Saleh Amran]

Hello
It's almost 2 months and i'm trying to learn the proper command to use for adding a watermark or a text writing on the stream.
Some of the BeIN Sports streams i have are protected with a text with the name of provider on the stream.

and i use them to restream its channels
so i want to know how to get a watermark or text writing on stream while streaming it.

I will give u an example. here!



and the command i use for restreaming is :

rtmpdump -r "rtmp://" -a "" -f "" -W "" -p "" -y "" --live | ffmpeg -re -i - -sn -vcodec copy -acodec copy -f flv "rtmp://"

Thanks.
