Glossary 205 27 Indices and tables 207 Python Module Index 209 Index 211 iii iv Mopidy Documentation, Release 3.2.0-17-g2cc7d953 Mopidy is an extensible music server written in Python. Mopidy plays music from local disk, Spotify, SoundCloud, Google Play Music, and more. You edit the playlist from any phone, tablet, or computer using a variety of MPD and web clients. Stream music from the cloud Vanilla Mopidy only plays music from files and radio streams. Through extensions, Mopidy can play music from cloud services like Spotify, SoundCloud, and Google Play Music. With Mopidy’s extension support, backends for new music sources can be easily added. Mopidy is just a server Mopidy is a Python application that runs in a terminal or in the background on Linux computers or Macs that have network connectivity and audio output. Out of the box, Mopidy is an HTTP server. If you install the Mopidy-MPD extension, it becomes an MPD server too. Many additional frontends for controlling Mopidy are available as extensions. Pick your favorite client You and the people around you can all connect their favorite MPD or web client to the Mopidy server to search for music and manage the playlist together. With a browser or MPD client, which is available for all popular operating systems, you can control the music from any phone, tablet, or computer. Mopidy on Raspberry Pi The Raspberry Pi is an popular device to run Mopidy on, either using Raspbian, Ubuntu, or Arch Linux. Pimoroni recommends Mopidy for use with their Pirate Audio audio gear for Raspberry Pi. Mopidy is also a significant building block in the Pi Musicbox integrated audio jukebox system for Raspberry Pi. Mopidy is hackable Mopidy’s extension support and Python, JSON-RPC, and JavaScript APIs make Mopidy a perfect base for your projects. In one hack, a Raspberry Pi was embedded in an old cassette player. The buttons and volume control are wired up with GPIO on the Raspberry Pi, and is used to control playback through a custom Mopidy extension. The cassettes have NFC tags used to select playlists from Spotify. Getting started To get started with Mopidy, begin by reading Installation. Getting help If you get stuck, you can get help at the our Discourse forum or in the #mopidy-users stream on Zulip chat. If you stumble into a bug or have a feature request, please create an issue in the issue tracker. If you’re unsure if it’s a bug or not, ask for help in the forum or the chat first. The source code may also be of help. If you want to stay up to date on Mopidy developments, you can follow the #mopidy-dev stream on Zulip chat or watch out for announcements on the Discourse forum. USAGE 1 Mopidy Documentation, Release 3.2.0-17-g2cc7d953 2 USAGE CHAPTER ONE INSTALLATION There are several ways to install Mopidy.

  • How to Use the VLC Media Player Together with Barix Products
    How to use the VLC Media Player with the Barix devices The VLC Media Player can be used to stream audio from the PC to the Barix Exstreamers or Barix Annuncicoms. But it can also listen to Barix encoders, like the Barix Instreamer and the Barix Annuncicom. It is a freeware software and can be downloaded from http://www.videolan.org . This document is referring to the current available VLC Media Player version 2.2.0 Streaming a file/playlist to Barix decoder To send a MP3 RTP stream from the VLC to a Barix Exstreamer execute the following steps: – first open VLC – select from VLC main menu : MEDIA – Open (advanced) … – there select your audio files (MP3) or your playlist file (m3u) – select “Stream” from the “Play” button menu A new window opens, click on “Next”. On next screen “RTP Audio/Video Profile” and click on “Add”. As next define target IP-address and target port number then click “Next”. On next screen set the target format “Audio-MP3”. “Transcoding” is mostly not needed and can be deactivated then click “Next”. As last comes the Summary/Option setup screen showing the command line for the before selected options, click on “Stream” to start the streaming. Such stream can be received e.g. from the “Barix Streaming Client” firmware, the “Any to All” firmware or the STL firmware. Option command for RAW UDP Streaming e.g. to Annuncicom :sout=#duplicate{dst=std{access=udp,mux=raw,dst=224.0.0.1:3030}} (String is for the Option Setup screen, see picture above, generates a RAW UDP multicast stream to port 3030) The target port number and/or target IP address at the end of the string is changable! Thereafter click on “Stream”.

  • Find Files and Do Stuff with GNU Find Serge Y
    Find Files and Do Stuff with GNU find Serge Y. Stroobandt Copyright 2014–2020, licensed under Creative Commons BY-NC-SA Introduction I can still remember how my first encounter with the find command infused a considerable amount of «shock and awe» in me. This had all the looks of cer- tainly not going to be an easy command to learn! Over the years, I painstaking- ly gathered a number find recipes which eventually led to the inception of this article. Nowadays, I find find hardly difficult.riting W this article helped a lot in get- ting a feel for find . Knowing that I can always fall back on this recipe collec- tion certainly also strengthened my present day confidence. Are you equally interested in becoming a find guru? Now, do yourself a favour and have a quick look at man find . Done? Let us continue then with some examples for fun and profit… When not to use find Gain speed with locate When looking for a hard to find file or directory that already exists for some while on your drive, do not use find but use locate instead. $ locate filename The reason is queries with locate execute much faster than with find. Unlike find , locate uses a previously created database to perform the search. This database is updated periodically from cron .Nevertheless, there are many in- stances where the use of find is required, albeit because find offers an -exec clause. Numerous examples are given below. 1 Unleash the power of globstar Here is a real-life example where I unleashed the power of globstar .
