Using Rygel and Lightmediascanner
Contents
Overview
Light Media Scanner
Lightweight media scanner (LMS) has been created for embedded systems. It uses SQLite for storing data. The project started in 2007. The source code is available at GitHub under GNU Lesser General Public License 2.1.
Rygel
Rygel is a home media solution. There is LMS plugin for Rygel.
Usage
Manually
The instructions below explain how to manually use Rygel and LMS to scan for multimedia files, list and share them over Universal Plug and Play (UPnP). It has been tested with the Tizen distribution for i.MX6 built with Yocto/OE and meta-agl, the Yocto Layer of Automotive Grade Linux (AGL).
- Ensure that the embedded device and your personal computer and in the same network.
- Ensure that Light Media Scanner (LMS), Rygel and its LMS plugin has been installed on the embedded device.
- Login as root on the embedded device.
- Ensure that /usr/share/media exists and place in it FLAC (with metadata) and JPG files.
- Type the following on the embedded device to start a message bus:
eval $( dbus-launch --auto-syntax )
- Type the following on the embedded device to launch Light Media Scanner:
lightmediascannerd --startup-scan --directory=/usr/share/media &
- Type the following on the embedded device:
ls ~/.config/lightmediascannerd/
- verify that lightmediascannerd has successfully created SQLite database:
db.sqlite3 db.sqlite3-journal
- Type the following on the embedded device to verify that lightmediascannerd has successfully retrieved the multimedia files and inserted the to the SQLite database:
sqlite3 ~/.config/lightmediascannerd/db.sqlite3 sqlite> .tables audio_albums audios lms_internal videos_audios audio_artists files playlists videos_subtitles audio_genres images videos videos_videos sqlite> SELECT * FROM images; 1|Jpeg||1352977249|3264|1836|0|0.0|0.0|0.0|JPEG_LRG|image/jpeg|jpeg 2|Jpeg||1352977246|3264|1836|0|0.0|0.0|0.0|JPEG_LRG|image/jpeg|jpeg 3|DSCN0024||1361553676|4320|3240|0|0.0|0.0|0.0||application/octet-stream|jpeg sqlite> .quit
- Type the following on the embedded device to launch Rygel:
rygel -c /etc/rygel.conf
- Install eezUPnP on your personal computer.
- Launch eezUPnP on your personal computer and verify that the embedded device and the lists of the mutimedia files on it are displayed.
Using Systemd services
- Ensure that the embedded device and your personal computer and in the same network.
- Ensure that Light Media Scanner (LMS), Rygel and its LMS plugin has been installed on the embedded device.
- Login as root on the embedded device.
- Ensure that /usr/share/media exists and place in it FLAC (with metadata) and JPG files.
- Type the following on the embedded device and verify that lightmediascanner.service is enabled:
systemctl is-enabled lightmediascanner.service
- Type the following on the embedded device and verify that rygel.service is enabled:
systemctl is-enabled rygel.service
- Type the following on the embedded device and verify that lightmediascanner.service is active and running:
systemctl status lightmediascanner.service
- Type the following on the embedded device and verify that rygel.service is active and running:
systemctl status rygel.service
- Install eezUPnP on your personal computer.
- Launch eezUPnP on your personal computer and verify that the embedded device and the lists of the mutimedia files on it are displayed.
