That's a bit of an ambiguous statement. TCP is layer 3, HTTP is layer
7, and uses TCP underneath.

Please always show us your complete, uncut console output together with
the command line.

I didn't know you could connect to :-)

I tried this:
$ ffmpeg -listen 1 -i http://localhost:8888/video -f null -
$ ffmpeg -f lavfi -i testsrc -t 1.55 -f mpegts

and my Wireshark tell me it's using HTTP:

Works perfectly for me.
