Here is a list of web sites that are related to the QStream project or that contain information that may be useful to QStream users.

• The Cooperative Fairshare Scheduler

This project is aimed at designing a new kernel task scheduler that can accomodate more than one time sensitive & adaptive applications running on a general purpose operating system. The idea behind this work originated from the basic event driven principles used by QStream. This is currently an ongoing research project carried out by a team of students working under Charles 'Buck' Krasic in the Department of Computer Science, University of British Columbia and under Ashvin Goel in the Department of Computer Science, University of Toronto.

• Extreme Video

QStream's roots are in Oregon with the research team of Jonathan Walpole, formelly at OGI, now at Portland State University (PSU). At PSU, Jon and others have started a project called Extreme Video. The Extreme Video team continue active work on QStream.

• GStreamer

The GStreamer project is an open source multimedia framework, probably the most famous one around. GStreamer and QStream have common roots, as Erik Walthinsen founded GStreamer while he was working for the Quasar team at OGI (the Quasar Video pipeline is the predecessor to QStream, and partly to GStreamer). Buck and Erik also started the LibDV project while at OGI. In some sense, GStreamer and QStream are working toward the same ends, but they each solve different problems.

• Subjective Impression of Variations in Layer Encoded Videos

The Multimedia Communications Lab (KOM) at Darmstadt University of Technology has done some interesting work on video quality adaptation. They used SPEG in their evaluation software.
