Rubio Contents 1 Tizonia Documentation, Release 0.1.0 2 Contents CHAPTER 1 Introduction 1.1 Introduction 1.1.1 500-foot view Tizonia is a free and open-source multimedia software project based on OpenMAX IL. OpenMAX IL is an open standard maintained by the The Khronos Group that enables the creation and integration of software and hardware accelerated media streaming components like audio and video encoders and decoders, camera components, and media processing algorithms. Tizonia provides a number of libraries that implement the various features and components of the OpenMAX IL API, including the OpenMAX IL Core, the OpenMAX IL plugin infrastructure, Resource Management and a number of plugin implementations (primarily audio and video software decoders, and media sources and renderers). From a user-side perspective, the Tizonia project also features a command-line music player and audio streaming client/server for Linux with support for Spotify, Google Play Music and SoundCloud on-demand audio streaming services. Tizonia development is hosted on GitHub and software binary releases are available for Debian-based Linux distribu- tions from Bintray. 1.1.2 Current features • Simple, no-fuss command-line music player utility. • Cloud audio streaming services: – Spotify Premium, Google Play Unlimited, and SoundCloud. • Support for most common high-quality audio formats from local media: – Formats currently supported: mp3, mp2, mpa, m2a, aac, vorbis, opus, wav, aiff, and flac. • Playback of Icecast/SHOUTcast radio streams: 3 Tizonia Documentation, Release 0.1.0 – mp3, aac, and opus stations (ogg to be added soon). • LAN audio streaming server (Icecast/SHOUTcast): – Currently: mp3 stations can be created from local media (flac and opus to be added in the near future). • MPRIS v2 remote control interface. • Based on Tizonia’s own internal multimedia framework. – A full implementation of the OpenMAX IL 1.2 provisional specification. – No ffmpeg, libav, gstreamer or libvlc dependencies. 1.1.3 Roadmap • LAN streaming (Icecast/SHOUTcast) of any audio stream (including cloud services). • Integration of additional audio streaming services (e.g. Dirble, YouTube, etc.). • Multi-room synchronised playback. • Zeroconf/AVAHI networking. • Music Player Daemon protocol support. • Hardware-acceleration and Video support. 1.2 Installation Debian packages are available from Bintray for the following distro/arch combinations: • Ubuntu Trusty (14.04) – amd64, i386, armhf • Ubuntu Vivid (15.04) – amd64, i386, armhf • Debian Jessie (8) – amd64, i386, armhf, armel • Raspbian Jessie (8) – armhf 1.2.1 Install the latest release To install the latest release, use the following shortcut to the install.sh script: $ curl -L -O https://goo.gl/Vu8qGR&& chmod +x Vu8qGR&& ./Vu8qGR Note: The install.sh script is hosted on GitHub. 4 Chapter 1.

  • Mdns/Dns-Sd Tutorial
    MDNS/DNS-SD TUTORIAL In this tutorial, we will describe how to use mDNS/DNS-SD on Raspberry Pi. mDNS/DNS-SD is a protocol for service discovery in a local area network. It is standardized under RFCs 6762 [1] and 6763[2]. The protocol is also known by the Bonjour trademark by Apple, or Zeroconf. On Linux, it is implemented in the avahi package. [1] http://tools.ietf.org/html/rfc6762 [2] http://tools.ietf.org/html/rfc6763 About mDNS/DNS-SD There are several freely available implementations of mDNS/DNS-SD: 1. avahi – Linux implementation (http://www.avahi.org/) 2. jmDNS – Java implementation (http://jmdns.sourceforge.net/) 3. Bonjour – MAC OS (installed by default) 4. Bonjour – Windows (https://support.apple.com/kb/DL999?locale=en_US) During this course, we will use only avahi. However, any of the aforementioned implementations are compatible. Avahi installation avahi is available as a package for Raspbian. Install it with: sudo apt-get install avahi-deamon avahi-utils Avahi usage avahi-daemon is the main process that takes care of proper operation of the protocol. It takes care of any configuration of the interfaces and network messaging. A user can control the deamon with command line utilities, or via D-Bus. In this document, we will describe the former option. For the latter one, please see http://www.avahi.org/wiki/Bindings. Publishing services avahi-publish-service is the command for publishing services. The syntax is: avahi-publish-service SERVICE-NAME _APPLICATION- PROTOCOL._TRANPOSRT-PROTOCOL PORT “DESCRIPTION” --sub SUBPROTOCOL For instance, the command: avahi-publish-service light _coap._udp 5683 “/mylight” --sub _floor1._sub._coap._udp will publish a service named ‘light’, which uses the CoAP protocol over UDP on port 5683.

  • A High-Level Programming Language for Multimedia Streaming
    Liquidsoap: a High-Level Programming Language for Multimedia Streaming David Baelde1, Romain Beauxis2, and Samuel Mimram3 1 University of Minnesota, USA 2 Department of Mathematics, Tulane University, USA 3 CEA LIST – LMeASI, France Abstract. Generating multimedia streams, such as in a netradio, is a task which is complex and difficult to adapt to every users’ needs. We introduce a novel approach in order to achieve it, based on a dedi- cated high-level functional programming language, called Liquidsoap, for generating, manipulating and broadcasting multimedia streams. Unlike traditional approaches, which are based on configuration files or static graphical interfaces, it also allows the user to build complex and highly customized systems. This language is based on a model for streams and contains operators and constructions, which make it adapted to the gen- eration of streams. The interpreter of the language also ensures many properties concerning the good execution of the stream generation. The widespread adoption of broadband internet in the last decades has changed a lot our way of producing and consuming information. Classical devices from the analog era, such as television or radio broadcasting devices have been rapidly adapted to the digital world in order to benefit from the new technologies available. While analog devices were mostly based on hardware implementations, their digital counterparts often consist in software implementations, which po- tentially offers much more flexibility and modularity in their design. However, there is still much progress to be done to unleash this potential in many ar- eas where software implementations remain pretty much as hard-wired as their digital counterparts.

  • Tiny Disco: a Cost-Effective, High-Fidelity Wireless Audio System ​ Quarter / Year Submitted: Winter 2020 ​ Student: (Print Name) ______(Sign) ______
    Tiny Disco: A Cost-Effective, High-Fidelity Wireless Audio System A Senior Project Report presented to the Faculty of California Polytechnic State University San Luis Obispo In Partial Fulfillment of the Requirements for the Degree Bachelor of Science in Computer Engineering By Luke Liberatore February 2020 Date of Submission: February 25, 2020 Senior Project Advisor: Hugh Smith Abstract The Tiny Disco is a WiFi based concert system, featuring improvements on popular “Silent Disco” concerts. Rather than being tied to compression and bandwidth restrictions present in traditional silent disco systems, the Tiny Disco system can deliver 320kbps+ audio quality, and allows listeners to bring their own headphones, further lending to the high quality audio experience. Tiny Disco uses a Raspberry Pi as the audio server, and Espressif ESP32 microcontrollers as audio receivers/clients. The Tiny Disco is primarily geared toward smaller concerts and niche events where audio quality is valued, though due to its WiFi-based architecture, it can be expanded to events of a few hundred people fairly easily. The Tiny Disco system was developed and tested, and performed successfully using a test setup. Only one client was tested due to cost constraints, but load testing was performed against the Raspberry Pi server, as well as bandwidth/audio quality analysis. 2 Table of Contents Abstract 2 Table of Contents 3 Introduction 5 Stakeholders 7 Project Goals and Objectives 7 Project Deliverables 8 Project Outcomes 8 Background 9 Experimentation to help develop
