Transcoded vs Non-Trasncoded Streams

[newgeneral10]

Sup,

 

So I got an Emby server (similar to Plex) running currently on a Freenas Box with an i3 6300.  So dual core with Hyperthreading.

 

When people talk about Emby/Plex performance, they always talk about transcoded streaming performance.  I think that means a stream playing at a different resolution, like playing a 1080p video at 720p.  But what about Non-Transcoded Performance?  Like is it normally double or triple the transcoded performance?  More?

 

I am more than likely going to test this myself (but not right now cuz i got sponsibilities) but I wanted to see if y'all had any insight first.  Thanks.

 

P.S. Idk if this is in the right section so feel free to move if necessary.

If a video is not being transcoded, then even a raspberry pi would be able to keep up with it - its just a straight file transfer at that point.

My 22 core can handle something like 7 transcoding streams at the same time with Plex max quality transcoding.

 

As said above, non-transcoded is basically just a file transfer and limited by the system's ability to handle file transfers.  I imagine most people run out of upload bandwidth before hitting a limit otherwise.

isn't there a SSE instruction set explicitly for streaming vids???

I literally have no idea what you're talking about... sorry.

SSE is one of many instruction sets that modern CPUs can implement - SSE is actually getting a bit old now. Whether programs are compiled to take advantage of different instructions depends on compiler settings and sometimes extra work done by the programmers. It's not something you have to worry about - either it is working or it isn't.

so very true

but SSE does have a streaming extension (SIMD i think) that does do h264 and h265
