626 Plex performance
Can anyone answer how well the 626 performs for Plex streaming? For example: 1. How many concurent 1080P streams can it transcode? 2. How many concurent 4K steams can it transcode? That sai...
It would be useful to get more data on this. It might help if plex could provide some metrics on the compute loads used by their encoders and decoders (ideally for various image sizes).

the newer versions of Plex/client now can simply copy over the H.262 video from MKV files without transcoding.
Just wanted to add that H.262 is more commonly known as MPEG-2 (used in DVDs and US over-the-air broadcast).

Sorry, I should have said H.264 is just streamed directly while H.262 is transcoded. I should also mention that VC1 used on some HD DVDs is also transcoded.
In general you need to transcode for tthree reasons:
(a) the receiver doesn't support the codec
(b) the receiver can't handle the image size
(c) the network can't deliever the bitrate.
Ideally the server would always transcode in these cases, and never transcode if that isn't necessary.

Agreed, and specifically for me it's due to the first option 'a'. I could get around it all if I wanted to re-encode my entire library and all videos moving forward but who has time for that. :smileysurprised: All my TVs/Rokus are 1080P capable and set that way. My entire house is wired for Gigbit with RJ-45 drops (some have multiple drops) in every room so that's never been the issue. Too bad we can't get to a standard we all agree upon so transcoding would be a complete thing of the past.
