Has anyone successfully streamed 4K films over their home network? I was playing about with a 4K rip last night an despite the network working between 60 and 90MB/s, the film stuttered and dropped frames. Is that level of network utilisation normal for such a task?
 
Hmmm... The film is encoded in HVEC265. If your figures are right then I don't see why I'm seeing network usage of between 60 and 90MB/s. Nothing else was being transferred before you ask.

I was using VLC to view the film if that makes any difference.

EDIT: VLC doesn't seem to support H.265! That's a shocker!

I'm assuming Win server is the server and OSX is the client, and I'm assuming you're using SMB shares?

Sounds like OSX buffers the whole file to local disk and then starts reading it while it's still buffering at full whack, instead of reading it directly/only when necessary.

Can you get a disk usage meter in the task manager for Mac? Sounds like your stuttering is caused by excess disk IO.

Your assumptions are right.

I've been trying VLC and 5kplayer, both of which exhibit the same issues. The thing is, a 1080p film plays fine. I don't see why a 4K film should be any different apart from the obviously larger file size.

I'll double check all these figures and provide more info if possible tonight when I get home. I'll also try the file directly on the client computer. Excessive disk I/O shouldn't be major issue as the client runs off an SSD so it should be capable of handling anything major.
 
Quick update. I never got to the root of the streaming issue... However, I did try the file locally and the same issues occurred in exactly the same places. Could just have been an iffy rip.

I'm currently downloading the files mentioned by jpaul to give them a whirl.
