repeat diskAccess @Emby:Sessions/Playing/Progress even when 'paused'?

Recommended Posts

I run Emby Server 4.7.8.0-704070800 on a 4-disk/RAID-10 Synology NAS DS918+ (DSM 7.1.1-42962 Update 1)

It serves as backend to LAN clients running Kodi 19.4/Linux with Emby for Kodi Next Gen v7.9.4 plugin.

Everything works as expected; zero problems serving up videos.

One minor issue that I've been trying to 'solve'.

If I launch a vid (either in client Kodi player, or in client browser to Emby webUI) and hit 'pause' -- so the movie's queued up to play, but not streaming -- I notice regularly repeating 4-disk access.  Every few seconds, all 4 of the NAS's disk-LED's blink and I hear disk access.  This will simply repeat forever, until I 'stop' the movie, rather than just 'pause' it.

I turned on debug logs to take a look, and see:
with access from Kodi client,

"Sessions/Playing/Progress" seems the common element.  Something constantly polling for progress?

Is this expected/normal behavior for Emby?
(How) can this be disabled, or tamed?

Hi, it's expected behavior to let the server know the app is still active so that it won't close the playback session. This will allow you to unpause seamlessly when you return.

hi.

ok, sounds like there's a default close time for closing a playback session ... right?

is there a config to change that time out?  i.e. make it (much) longer? so that this disk access is less frequent?

no, this is not a critical issue.  yes, i'm being whiny about it.  the NAS is close to me, and every time I pause (to e.g. take a call), this disk access keeps scratching away in the bkgd.  driving me nuts! kindof like water torture 😉

There isn't, but even if there was, that would prevent client apps from checking in every ten seconds.

What you're reporting here is something we can keep in mind as we continuously revise the way these communications work.

fair enuf.

might be useful to be able to declare a connection as reliable/static vs intermittent/dynamic.

e.g., my lan kodi client conencting to my lan emby server can reliably be considered 'up' and available from the moment it connects to the moment it disconnects.  as would the web UI client AT my emby server ... that one in particular seems a pretty safe bet.

yeah, the client would need to be notified -- but, seems to me a passive listener at the client, waiting for a notify from the server is good enuf.  no need for an active interrogation/keepalive from client -> server.

and, nope, haven't thought this thru much yet.

Maybe worth looking at if the disks (firmware) or nas support acoustic management utilities for the HDD's.     

I know you can put them in 'quiet' mode where I presume it uses a different caching algorithm to keep the heads in place for longer.

fyi,  after upgrading emby server to

emby-server-synology7_4.7.10.0_x86_64.spk

it's gotten a bit 'worse' ,

now, i get these drive seeks not just when kodi's launched & paused, but *always* when kodi's launched -- whether paused or playing media

Good idea, where supported: https://linuxconfig.org/how-to-reduce-hard-drive-s-acoustic-noise-level

Unf
ortunately, here:
 

hdparm -M /dev/sda

  /dev/sda:
   acoustic      = not supported

for all my drives (WD Red, on this NAS)

Is there another method to check app activity, without causing disk activity?

Those calls don't write to the database, so I really don't think those will cause high disk activity. The enabling of debug logging might though. I would suggest attaching the complete emby server log for analysis.

With debug logging OFF, looking at the Synology TaskManager's service list, I'm seeing an Emby disk write of ~ 20KB at each one of those 'seeks', every few seconds.

With, or withOUT debug logging?

 

With debug logging OFF, while Kodi's connected to Emby backend, paused in a media play, here's the log tail:

atm, it's seeking ~ every 4 seconds ...

It's not seeking, it's just reporting it's position to the server for display and remote control purposes.

It's not seeking, it's just reporting

in any case, it's accessing access.  about every four seconds.  'noisily', to the point of being unpleasant ...

perhaps an option to write -- without disk access -- to memory instead?

Luke covered it quite well. Yes next-gen plugin reports the status every 4 seconds. I can change it to 10 seconds or even more (@Luke, what's the maximum time before Emby server timeouts the session?)

I can also add an option to disable the keepalive, not sure what the side effects would be.

btw. @Luke next-gen plugin also pings the server via websocket every 10 seconds to detect if the connection is still up.

Would it be possible using the websocket ping at least for session keepalive determination? As far as I know, Emby server was capable receiving playback-session-status-reports via websocket, but I think this feature is broken for a long time.

Luke covered it quite well. Yes next-gen plugin reports the status every 4 seconds. I can change it to 10 seconds or even more (@Luke, what's the maximum time before Emby server timeouts the session?)

I can also add an option to disable the keepalive, not sure what the side effects would be.

btw. @Luke next-gen plugin also pings the server via websocket every 10 seconds to detect if the connection is still up.

Would it be possible using the websocket ping at least for session keepalive determination? As far as I know, Emby server was capable receiving playback-session-status-reports via websocket, but I think this feature is broken for a long time.

 

 

Our guidance is every 10 seconds, and then immediately following any manual user action (e.g. seek, pause, unpause, etc).

@quickmic

here, it's currently definitely more frequent that every 10s ...

iiuc, a websocket keepalive wouldn't require any disk access, is that correct?

Both, the session (http) status report and the websocket ping should not trigger any disk io.

Do you use native mode in next-gen? If yes, Kodi has direct file access to the server and theoretically, Kodi could access files (even it shouldn't). In addon mode, it's not possible.
