Linux user / permissions issue

[tdiguy 96]

I have been trying to change the user that emby runs as so that i can work permissions to be really specific for emby use. It seems like emby completely ignores that i have changed the user it should run as though. I changed :

/etc/emby-server.conf

 

add EMBY_USER=Media

 

But i still see emby running as emby.

What am i doing wrong here?

Did you restart the server after making this change?

[tdiguy 96]

I think i had rebooted the whole pi.. But i will restart again to be sure.

Well, once i am done re-compiling ffmpeg to support omx. Forgot i had that running.

Ok i was able to get some more feedback restarting the emby server from the CLI.

It gives me the following:

/etc/emby-server.conf: line 23: add: command not found

So i had the formatting all wrong.

correct format is

EMBY_USER=<username> 

 

One thing thats kinda weird to me. I dont have a emby user set up on my pi. Yet emby has no issue running as emby. 

I ended up electing to just use emby since the user doesnt actually exist and yet i can grant emby permissions. It all seems kinda weird to me but its working well.

Ok so i have most of my emby server back up and running except i cant seem to get it to convert media.

I have the folder syn plugin installed. It just says failed when i hit convert.

I have attached the server log no idea what all this is saying.

Did you forget to attach it!

[tdiguy 96]

Lol looks like it.

And the sync ffmpeg log?

[tdiguy 96]

I somehow managed to make my pi unresponsive remotely. I had just uninstalled and re-installed mono because i noticed it was 5.2 and if i remember correctly 4.8 was the desired version. i will have to look at this sunday some time since my wife is also going out as soon as i get home. 

I think i am getting to the newb stage where i know just enough to be really dangerous with linux.

[tdiguy 96]

Ok I don't see a ffmpeg log but it seems to do nothing when i hit convert. I have a conversion set up that shows under download and syn but hitting convert media doesnt do anything.

I hope this helps. I am going to attach some screenshots of my setup that i think are relevant.

O also of note. I have emby run as smith finally got that to work.

OK i finally found it. I swear it wasnt there before.

I am seeing

Which is a bit odd I think this is from misconfigured options on ffmpeg, but right now i am using the system installed ffmpeg. Going to disable hardware acceleration and see if that helps.

[tdiguy 96]

ok, i have no idea why this is not working.

[Luke 37083]

Try turning off omx

[tdiguy 96]

So I have been able to narrow things down a little. Transcoding seems to be working. I recorded a show last night and i can play it back via web browser, its not great since transcoding is a bit much for the pi in general. 

But when try to get emby to convert the media its still not doing anything.

[tdiguy 96]

Would this error be related?

Please attach the complete log file. Thanks.

[tdiguy 96]

this is the system log. I dont think ffmpeg is generating  a lot when i try to syn.

 

I am on mono 5.2 I have been trying to figure out how to downgrade to 4.8.1 but its been a pita.

[Luke 37083]

ok, yes I would suggest 4.8.1.

[Jdiesel 1114]

Downgrading Mono is a PITA, it can be done but expect to have issues with dependencies not being met when you try to install the older version. I'm sure there is a proper way to easily do it but I fought with it for a day last time I needed to.

Yea i have been trying to downgrade it. I dont actually understand why 5.2 was installed in the first place honestly unless its also listed in stretch backports repo. I pinned my repo to the snapshot 4.8.1 in wheezy which i thought was the way to go about ensuring mono did not update to anything past say 4.8.1

[Luke 37083]

The upcoming Emby Server 4.2 release will have improved hardware transcoding support for both RockPro64 and Raspberry Pi. Thanks guys.
