4K is becoming more common today with more and more content, media and hardware including TVs are supporting 4K. There are even some 8K TVs hardware alvailabe for sale now.
As we know 4K is larger in media size due to its resolution and requires more CPU power and network throughput as oppose to conventional 720 or 1080.
Out of the box, by default PMS is configured to trans-code from 1080 to 720p during streaming.
This question is more critical when you have multiple simultaneous streaming at the same time.
QUESTION:
Assuming you have plenty of CPU power and proper hardware can PMS handle 4K smoothly?
Can PMS support smooth 4K streaming not only locally but remotely?
I would appreciate the answer from those who actually live 4K today and stream it on daily bases. Has PMS been consistently tested with 4K?
Thanks in advance.
Yes, I have a large 4K HDR Library. I think you’re asking the wrong question here though, it’s not CPU power, but bandwidth. You shouldn’t be trying to transcode 4K so at that point, there’s no CPU involved… Realtime 4K Transcoding requires large hardware requirements (CPU and GPU), and honestly just isn’t worth it… You’re in 4K/UHD because you want the best picture quality available to you, so why would you ever consider attempting to have your computer transcode it?
Yes, IF you have the upload, 4K media commonly goes above 100Mbit/s I remote stream 4K HDR
Only remotely. It always tries its best to direct play locally assuming the client can handle it.
Most of what you are asking is in here.
Regardless of the above the beta transcoder engine will happily transcode 4 x 4K Remuxes down to 2Mbps with little effect on my KabyLake using QuickSync.
But the fact that it can doesn’t mean I would (currently at least) set up my system to share 4K with people who cannot take advantage of it.
I looked at the link about 4K.
I do have the hardware and bandwidth.
However there are two questions since by default PMS set to trans-code from 1080 to 720 for remote sessions.
There is no question that for local direct play by default is the best option. however, I am specifically asking about REMOTE connections.
Assuming remote connection supports both hardware and bandwidth does it have smooth 4K direct play?
What if remote is 1080 TV then what will happen if you are forcing direct 4k play by changing PMS remote default?
Thanks again
I answered this question above… Yes, if you have the bandwidth to support a remote session, 4K works fine, but bare in mind, 4K movies often hit bitrates over 100Mbit/s so you’d need AT LEAST that to support the outbound stream… Not even including packet overhead, and the routing between you and the client
So the issue here is that on the internal LAN server, for home use only, there is no option available to set Remote Access to Original. It doesn’t exist because remote access to this server is disabled. Is there a solution how to play 4K content DIRECT = Original on server which has no internet access, only LAN connection?
