Max threads stuttering stream

[p_parente 0]

I'm brazillian, so forgive me for my english.   

I was messing around with the transcoding settings (since I use a chromecast at home and HEVC is not supported) and found out I cannot use the maximum thread count without the stream stutters every 5 seconds or so. According to CPU-Z, I can use 4, if I am correct:

 

The maximum I can use to play smoothly is 2, anyone knows why this happen?

Hi, what do you mean by maximum thread count?

[pwhodges 2015]

There are only two cores.  The extra threads enabled by Hyperthreading are not as capable.

The maximum number of threads the CPU will use to transcode, normally it stays on "Auto" I think.

But why does that stutter the stream? I'm very noob with this stuff... I'm playing it on chromecast, my CPU is just transcoding... And it seems to be doing it fine by the painel. If I was watching on the PC i would get it, but why does chromecast gets affected?

Logs would show more information but basically it sounds like the processor can not process the media fast enough to keep up with the playback.

 

Cores and threads do not mean that is how many transcode streams you can have.

Anything that needs transcoding could be affected. Let's look at an example.

By setting that to a higher number, you are telling Emby to try and do more things at once than if it were a lower number and your CPU simply cannot handle that load.  Basically, you've put too many bags on the camel's back.

 

Does that makes sense?
