FFmpeg support a wide varity of network protools, from low level
tcp&udp to higher level http, ftp, rtp, rtsp, rtmp, mms, ...

the AGPL requires "if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software."

yet you here suggest to link AGPL software to GPL where the GPL sw
will not offer any source though any of its quite numerous network

Iam no lawyer so i dont know if you can do that or not but
either the combination needs to offer source code through its network
protocols or you just suggested to circumvent your own licenses main
