4K streaming through Plex on Samsung UN65KS8000 buffers. Is this common?
I've been reading some posts here and it seems some people seem to speak about this same issue here.
I'm running my PMS locally on an i7 4790k CPU running at 4.5ghz. 16GB of ram (also using Samsung 850 SSD and Nvidia GTX 1080 in case this matters for some reason). My PC is hard wired into my router and my TV is hard wired into my router so I have a stable connection between all devices. My current internet plan also provides me 300+ mbps download speeds. I am playing all movies through the Plex app on the Samsung TV. I've also tried this through Plex on my Xbox One S and found the same results.
Playing all 1080p videos have given me zero issues regardless of the size. Whether they are 25 GB .mkv files or smaller. I recently just bought this tv and was pretty excited to try some 4K movies so I acquired a few. The Revenant, Star Trek Beyond and Pacific Rim all in 4K with file sizes varying between 65 to 85GB.
To my surprise these files cause severe buffering. Some times every 10 seconds and sometimes every 20 seconds or so. I am currently "streaming them" at "original" quality as I assumed this wouldn't be an issue. Apparently I assumed wrong. I always thought that the streaming was dependant on my internet speeds. Being I can download over 300mbps I figured that I'd have no issues. Later research taught me the issue likely lies with transcoding.
I tried a suggestion by someone on the forums by "optimising" all these films. I wasn't expecting to see that doing this at "original quality" would take literally half a day. One film refuses to optimise and keeps failing. The other 2 completed and converted to MP4.
Playing these new .MP4 4K files worked fine and they played without any buffering however, fidelity in the picture depreciated regardless of optimising at "original quality".
Does an easy fix exist for this issue? Am I trying to accomplish something that currently just isn't possible? Is there just some settings I can adjust in my PMS server to resolve this? I have my transcode speed set to "fast" in the PMS settings and "Make my CPU Hurt". Figured that would be good enough but clearly it is not.
