GSoC - DLNA UPnP A/V integration
I will use this page as a placeholder for details and progress information about my SoC 2008 project.
The project
Abstract
Even if it is controverted, UPnP A/V Is a widely used standard set of protocols for networked digital audio and video equipment interoperability, thus making it almost a requirement digital media software that aim to become real part of the average multimedia home network. This project aims to implement at least the Media Server part in VLC media player, which will enable it to advertise and stream media to DNLA UPnP A/V enabled devices, such as the PlayStation 3.
Goals
At the end of the project, VLC media player will be able to advertise its currently playing stream or playlist / media library / discovered services to UPnP clients, that will be able to play them over the network, using DNLA UPnP A/V protocols. VLC media player will also expose its web based interface to permit FreeBox's FreePlayer[2]-like features for UPnP devices. As a secondary goal, VLC media player's current UPnP capabilities will be improved with room made for future further UPnP support (Media renderer, Control point...). The reference for success will be the ability to be discovered by, and stream to a PlayStation 3 device.
Details
There are two possible ways to achieve that goals: Implementing the needed services inside VLC media player as modules, written in C (This is the preferred one, and I'm assuming that it will be used), or integrating the Coherence[3] python UPnP framework. Basic UPnP support will be provided through libupnp[4], which is already used in VLC media player for UPnP devices discovery. The UPnP A/V MediaServer specification[5] will be implemented as a module which will provide the ConnectionManager[6], ContentDirectory[7] and AVTransport[8] services as described in their respective specifications. Media will be streamed using the VLC media player's streaming capabilities. The ConnectionManager service will implement the optional PrepareForConnection() action in order to select a streaming protocol matching with the remote device's capabilities, and to be able to stream to multiple UPnP devices simultaneously. The ContentDirectory service will expose the playlist, the media library and the discovered services for remote playback. The AVTransport service will enable playback control from a remote UPnP device. Libdlna[9] will be given a close look, may it be for linking to it, or to use it as reference code.
