I would think a rasPI 3 should be able to deliver a single stream of 50 Mb/s on its ethernet port provided the data is read from an attached HDD. That should be more than enough for rather demanding video material. (But I have not tested it because I lack such a file.)
I suspect your bottle neck is somewhere else down the line. Aren’t you getting any messages.
Well, this is not actually true. RPI3’s builtin ethernet port is only 100 Mbps and share the same USB2.0 bus (480 Mbps) with other devices, including USB HDD. In a perfect world the maximum bus width would be 60 MB/s, while network interface speed would be 12.5 MB/s. In the real world, which is far from perfect, the best values you can get are ~40-50 MB/s for the bus, respectively 9-11 MB/s for the network. So you won’t be able to stream more than 11 MB/s over the network.
PS. I’ve heard you can almost double the network bandwidth near ~18-20 MB/s, using a USB3.0 gigabit network adapter - this is the best you can get from RPI3.
