+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.
+. Stop emby and restore the original unit file.
+<code>service emby-server stop</code>
+. Verify that the unit file has the original ExecStart command:
+<code>systemctl show emby-server |grep ExecStart</code>
+. 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>
+. Exit and save the override file. Y and enter for the prompts.
+. Start the Emby server. And run top/htop to verify the new nice value.
+<code>service emby-server start</code>
