Open Source Video Interoperability

BEK : piksel : piksel04
An interesting set of pages describing a conference, some open source software and documentation regarding efforts to provide interoperability between open source video based applications. Of note is Livido a plugin framework, VideoPiping (sending raw video via named pipes from one app to another), Vloopback and so on.
Here is what they say on the site:
Piksel is a framework of tools and libraries which aims to provide interoperability between various free software applications dealing with video manipulation techniques.
The current focuses of the project are: implement a library for plugin dinamicly loaded video processors and colorspace transformations; develop of a standard set of control commands for interoperability between media applications, providing a library implementation which makes it easy to be embedded into softwares.
This project has its origins at the Piksel meeting held at the Bergen Center for Electronic Arts, in which authors from various free software applications met to settle common specifications: EffecTV, FreeJ, LiVES, MoB, PD/PDP, VeeJay.

Linux set top box

My Settop Box
Very interesting is the Knoppmyth section.. Looks like a Knoppix/MythTV distro.
From the site:
The purpose of mysettopbox.tv is to provide you the end user with the knowledge needed to assemble your very own settop box using Linux. Utilizing open source software and off the shelf hardware you’ll be able to assemble a box that has the following functions:
PVR
Jukebox
Image viewer
Game station

Apache, meet BitTorrent, BitTorrent, meet Apache

mod_torrent
From the site:
Mod_torrent is a drop in solution for Apache servers when deploying the BitTorrent file swarming technology. With mod_torrent your visitors share the bandwidth burden when distributing large files on your web site. The module transparently makes all, or optionally only certain types of files, retrievable by any client implementing the BitTorrent protocol.

Open source QuickTime initiative

OpenQuicktime – a new Quicktime Library
Very interesting project, includes a beta version of a broadcasting app as well.
From the site:
OpenQuicktime aims to be a portable library for handling Apple’s QuickTime™ popular media files on Unix-like environments. It is aim is to provide encoding, authoring and editing support as well as video playback.

Documentating a defense of open source

Welcome to the Grokline Project: Grokline’s UNIX Ownership History Project
From the site:
This is an open, community-based, collaborative research project, a living history, designed to carefully trace the ownership history of UNIX and UNIX-like code with the goal of reducing, or eliminating, the amount of software subject to superficially plausible but ultimately invalid copyright, patent and trade secret claims against Linux or other free and open source software. If there is any code out there that represents a conceivable risk of that kind, we’d like to identify it and mitigate the litigation risk now. If there isn’t any valid claim that can be made, we’d like to be able to prove it.
