[FFmpeg-user] zmq filter setup

[kamal shadi]

Oops, Yes the problem was with naming. now it works beautifully. thanks
much

One other question: How do you simulate a couple of livestream feeding into
ffmpeg? is the "-re" argument close enough? is there any other setup that
makes the simulation closer to the live production environment?

Also, tangential to the above question, can the filter_complex be hardware
accelerated on GPU?

thanks much.
