I’m running my Plex server on a Core2Quad Q6700 with 8GB of RAM. The OS is Centos 7.6 with no GUI. It can transcode x265 480p content to a Roku stick (x264) fine, and all my other boxes are Roku Ultra and PMP clients, which play natively.
If I stick a 4GB Nvidia GTX960 in it and loaded up the Nvidia drivers, think it would transcode 1080p x265 to x264 in hardware?
I also have an older Core2 Quad, but mine is a Q9650, with 8GB of RAM and using on board graphics… I have two servers with this combination, one with Windows 7 and the other runs FreeBSD 11.2…
The trick to running PLEX on older hardware is to encode your media properly the first time so it will direct play to your Roku devices… Luckily there is someone who has already done all the hard work and finding the best settings to use with Handbrake to encode your media so PLEX does not have to re-encode your media every time you watch it… Please check out Rokoding… Using the settings there, none of my media needs to be re-encoded to play on any of my Roku devices… I can stream 3 different 1080p h264 files at the same time locally and my CPU never even breaks a sweat, under 5% utilization!!!
I appreciate the reply, however it did not actually address my question. To recap: would an Nvidia GTX960 do hardware transcoding from x265 to x264 on a headless Centos 7.6 install?
I just spent hundreds of hours transcoding my collection to x265, and this Roku stick is only temporary for a guest who will be with us for a couple months, so I have no intention on transcoding everything again. Swapping graphics cards would only take minutes, and can be reverted when the guest leaves.
