Hi guys, I noticed on higher resolution movies such as 4K 57MBps streams, there is buffering on Samsung TV even through both the TV and the server are plugged in via ethernet. Transcoding takes the resolution down to 1080p 20MBps which is a serious drop but fixes the issue.
For the 4K, what’s the bottleneck for playing the 57MBps and is it addressable?
There are potentially a myriad of variables. The most common one at that resolution and bitrate is the use of subtitles.
If you’re using subtitles, and they’re bitmap subtitles, the transcoder will be invoked to burn the subtitles into the video. Is the CPU capable of handling that load focused on essentially 3 threads?
The second concern is indeed the network itself. 57 Mbps video on a 100 Mbps wire means you’re transporting ~75 Mbps in total inclusive of all overhead. Is all the equipment between server and television capable of sustaining that load?
I ask this because running 58 Mbps 4K over 300 Mbps N band wifi is easily done.
Thanks Chuck. There are 2 GigE switches between the TV and the server but should easily be able to handle it. Both also have wireless capable but I haven’t tested it on wireless yet. There are no subtitles that were turned on either.
The CPU should be able to handle it. It’s a I7-6700k
