simple, add server support for this to FFmpeg.

FATE is run in cases without network access (for example googles ossfuzz setup
i belives does not permit the fuzzed code to access external things IIRC)

The practice of implementing only one end of a protocol is honestly wrong.
And if there is no usable free server, then even more so.

If you drop bombs on a foreign country and kill a hundred thousand
innocent people, expect your government to call the consequence
"unprovoked inhuman terrorist attacks" and use it to justify dropping
more bombs and killing more people. The technology changed, the idea is old.
