Sleep prevention not working

[M1tch 2]

I saw this a few times on the windows server and ended up just setting sleep in the os to 3 hrs.

 

The Mac appears to do the same I have tried 15 and 30 mins and each time the server sleeps mid stream to a Samsung tv .

 

Anything else I check ?

Hi, on MacOS we don't currently have any sleep prevention so you'll need to configure it in system settings. It's something we plan to add in the future. Thanks.

[M1tch 2]

That would explain it then! Thanks Luke

[M1tch 2]

For anyone searching for similar, here is a stop gap that works pretty well until the Emby team add it in the future. I can't take credit I just reused from a cool script from "Parnty" here https://forums.plex.tv/t/plex-server-should-keep-mac-awake-after-wake-on-lan/60590/3

 

 

It checks the last 20 lines of the Emby Server log file for "emby/Sessions/Playing/Progress" every 30 secs and uses caffeinate to keep the mac awake.

When it can't see that string the assertion gets removed and the mac sleeps per the system settings.

 

Note: I may try to change this to look for any update to the log file as if emby is updating metadata etc the playing/progress piece gets lost in the noise. If anyone has a better way to approach i'd been keen to hear as i'm no dev..

 

 

1. Create ~/Library/LaunchAgents/embyCaffeinate.plist as follows:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>embyCaffeinate</string>

    <key>ProgramArguments</key>
    <array>
        <string>sh</string>
        <string>-c</string>
        <string>"$HOME/Library/Scripts/embyCaffeinate.sh"</string>
    </array>

    <key>RunAtLoad</key>
    <true/>
    <key>KeepAlive</key>
    <true/>
</dict>
</plist>

2. Create ~/Library/Scripts/embyCaffeinate.sh as follows:

#!/bin/bash


# Paths
embyLog=~/emby-server/logs/embyserver.txt 
caffLog=~/emby-server/logs/Caffeinate.log

# Kill subprocess on exit
trap '[[ -z "$(jobs -p)" ]] || kill $(jobs -p)' EXIT

# Functions
timestamp()      { date "+%b %d %H:%M:%S"; }
today()          { date "+%d"; }
embyUpdateTime() { stat -f %m "$embyLog" 2>/dev/null; }
embyUserAction() { tail -20 "$embyLog" | \
                   grep "emby/Sessions/Playing/Progress" | \
                   tail -1 2>/dev/null; }

# Init globals
initDay()        { day=$(today); }
initembyState()  { updateTime=$(embyUpdateTime);
                   userAction=$(embyUserAction); }

# Day check
isSameDay()
{
    local myDay=$(today)
    if [ "$myDay" = "$day" ]; then
        return 0
    else
        day=$myDay 
        return 1
    fi
}

# Idle check
isembyIdle()
{
    local myUpdateTime=$(embyUpdateTime)
    if [ -z "$myUpdateTime" ] || \
       [ "$myUpdateTime" = "$updateTime" ]; then
        return 0
    else
        updateTime=$myUpdateTime
        return 1
    fi
}

# Housekeeping check
isembyHousekeeping()
{
    local myUserAction=$(embyUserAction)
    if [ -z "$myUserAction" ] || \
       [ "$myUserAction" = "$userAction" ]; then
        return 0
    else
        userAction=$myUserAction
        return 1
    fi
}

# Wait until user has finished using emby
waitForUser()
{
    initembyState
    while true; do
        echo "$(timestamp) Caffeinating..." >> "$caffLog"

        sleep 120

        if isembyIdle;         then break; fi
        if isembyHousekeeping; then break; fi
    done
}

# Check emby and caffeinate if needed
initDay
initembyState
while true; do
    sleep 30

    # Rotate logs
    if ! isSameDay; then mv "$caffLog" "$caffLog".1 2>/dev/null; fi

    # Check emby
    if isembyIdle; then
        echo "$(timestamp) emby is idle" >> "$caffLog"
    elif isembyHousekeeping; then
        echo "$(timestamp) emby is running background tasks" >> "$caffLog"

    # Caffeinate
    else
        echo "$(timestamp) Caffeinate" >> "$caffLog"
        waitForUser &
        caffeinate -is -w $! 2>/dev/null
        echo "$(timestamp) Caffeinated" >> "$caffLog"

        initembyState
    fi
done

 

3.In Terminal, run the following

chmod a+x ~/Library/Scripts/embyCaffeinate.sh

launchctl load ~/Library/LaunchAgents/embyCaffeinate.plist

Hi, that's great info, thanks !

[Luke 37023]

The beta server has this now if you'd like to help test that:

Thanks.

Thanks.

up for testing - link to beta not working at the moment

We'll have a new one for MacOS up soon. Thanks.

Is sleep prevention working?
Seemed to go to sleep in the middle of playback on my M1 Mackbook Pro.

Hi, do you have wake for network access enabled on your mac?

https://support.apple.com/en-in/guide/mac-help/mh27905/mac#:~:text=Mac desktop computer-,On your Mac%2C choose Apple menu > System Settings%2C then,may need to scroll down.)&text=Turn on “Wake for network access” on the right.

Yup, it's enabled, seems to have been on by default. For now I still have to run `caffeinate` while playing.

What version of macOS are you on?

[Luke 37023]

Also, try playing something from an Emby app, and then while it's playing, enter this into the macOS terminal:

pmset -g assertions

That will list the processes that are keeping the system awake. It may take up to five minutes from when playback starts until Emby Server gets listed there.

[macv 2]

MacOS 13.2.1 (22D68)

`pmset -g assertions` did show emby strangely still shut down if I don't also run caffeinate

   pid 71684(EmbyServer): [0x0004b92f0001a534] 00:21:58 PreventUserIdleSystemSleep named: "Emby Server has active sessions"

 

[Luke 37023]

What does it say when you run caffeinate?

[macv 2]

I like to run it with the -d option so it says 

   pid 95536(caffeinate): [0x0004fbf50005a116] 00:00:06 PreventUserIdleDisplaySleep named: "caffeinate command-line tool"
	Details: caffeinate asserting forever
	Localized=THE CAFFEINATE TOOL IS PREVENTING SLEEP.

Without -d, it says the same thing as emby:

   pid 95150(caffeinate): [0x0004fad20001a058] 00:00:02 PreventUserIdleSystemSleep named: "caffeinate command-line tool"

Haven't tested emby playback without the -d, might be worth trying for someone (I'm traveling today & out of action for next few weeks).

When it sleeps, how long does it take to do so?

around an hour, laptop is always plugged in

[Luke 37023]

what Emby app are you playing from?

[macv 2]

Roku and Nvidia Shield (cigar version)

[Luke 37023]

When you run it with the -d option, what does that produce for Emby Server?
