====== Emby Server Little helpers ======

Linux File Permissions

<code>
setfacl -m user:emby:rxw /mnt/videos
</code>

<code>
setfacl -m user:emby:rxw /home/myusername

 

or to grant "read only" access to specific folders:

 

setfacl -m user:emby:rx /home/myusername/Music

 
setfacl -m user:emby:rx /home/myusername/Videos
 
setfacl -m user:emby:rx /home/myusername/Pictures
 
Since Live TV must be read and written, then it's neccesary to grant "read" and "write" permissions:
 
setfacl -m user:emby:rxw /home/myusername/LiveTV

===== Linux Shell Convert Videos with Emby NVIDIA HW transcoding =====

First,  may need to add Emby libraries to Linux:
<code>ln -s /opt/emby-server/lib/libavdevice.so.59 /usr/lib/; \
ln -s /opt/emby-server/lib/libavfilter.so.8 /usr/lib/; \
ln -s /opt/emby-server/lib/libavformat.so.59 /usr/lib/; \
ln -s /opt/emby-server/lib/libavcodec.so.59 /usr/lib/; \
ln -s /opt/emby-server/lib/libpostproc.so.56 /usr/lib/; \
ln -s /opt/emby-server/lib/libswresample.so.4 /usr/lib/; \ 
ln -s /opt/emby-server/lib/libswscale.so.6 /usr/lib/; \
ln -s /opt/emby-server/lib/libavutil.so.57 /usr/lib/;</code>

Then You can convert videos using Emby ffmpeg.
Example for HEVC:
<code>for i in *.mkv; do /opt/emby-server/bin/ffmpeg -y -start_at_zero -init_hw_device "cuda=cuda:0"  -i "$i" -map 0:v -map 0:a -c:v:0 hevc_nvenc -c:a copy  "${i%.mkv} - HD.mkv";done</code>

Or scale down:
<code>for i in *.mkv; do /opt/emby-server/bin/ffmpeg -y -start_at_zero -init_hw_device "cuda=cuda:0"  -i "$i" -map 0:v -map 0:a -vf scale="iw/2:ih/2"  -c:a copy  "${i%.mkv} - HD.mkv";done</code>




===== Set niceness for the emby service =====

Clean way to do this is with a service unit override.

1. Stop emby and restore the original unit file.
<code>service emby-server stop</code>

2. Verify that the unit file has the original ExecStart command:
<code>systemctl show emby-server |grep ExecStart</code>

3. Create a unit override to add the Nice parameter. This will open an editor where you can add Nice=-5 to the service block.
<code>systemctl edit emby-server</code>

Add:
<code>
[Service]
Nice=-20
</code>
4. Exit and save the override file. Y and enter for the prompts.

5. Start the Emby server. And run top/htop to verify the new nice value.
<code>service emby-server start</code>
