High CPU use with 1080p moives

He means PMS I believe.

Actually both I'm trying to figure out why I never meet this "high CPU power usage" with my MPB and with a macbook air... indeed I used this two laptops before to run PMS with Plexconnect in the same config

23
In fact I did only one thing differently : the 
I followed this process and the one through the USV cable as I did with my previous config:

This should be the explanation?

Not seeing the specs for your MBP I could only guess they may be significantly better than the mac-mini.  Regardless, do the experiment, remux the 1080 movie plus the subs into one mp4/m4v file.  Run that and test your cpu usage on the mini to see if there is a difference.

25

Or just run it without the subs and see if that makes the difference

26

Same issue without subs...

27

I still don't really see the issue...

If you need to transcode your stuff someone has to do the decode/encode of the file. What's wrong with the processor at full load for a while? Have you ever checked if the processor load stays high for the complete duration of the movie or falls back down pretty soon?

It might be interesting what priority setting the transcoder process uses... does it stop you from working on the Mac? Would it willingly reduce load if another task comes along?

28

@Baa The process remains at full load during all the movies... And the associated fan noise is just impressive.

 How can check that "priority setting the transcoder process uses"

I have just made another test with my previous config (running PMS and plexconnect on a Macbook air) and now same high CPU usage due the "Plex New Transcoder" so it seems that it not linked to the hardware...

>> The process remains at full load during all the movies...

Just to make sure "during all the movies" is...

1) for all the movies (but only at the beginning).

2) for the whole time replaying one movie.

3) for the whole time playing every movie, independent of the format(?).

Pick one... :-D

30

All my movies tested are 1080p mkv 

I would pick your first one but "beginning" will depend of the movie from some it is few minutes and others 30-50 minutes...

31

And what about the movie sound? Because I do need 5.1 surround can I manage trough the plexconnect setting?

And thanks to all that have spent time trying to help, really appreciated :D

32

In advance settings of the PMS you can set it to multichannel audio.

Could be… I update my Plex Media Server to 0.9.8.12 version it is slitty better. Indeed now with some mkv 1080p movies there no high CPU power used

i have confirmed this issue. The issue started with PLex New transcoder- with Version 0.9.8.14
