Google Summer of Code 2008

Panorama Viewing

Abstract

The goal of this project is to make VLC a one-stop solution for viewing panoramas of various formats. Currently, FreePV is the best/only cross-platform, non-proprietary solution for viewing QuickTimeVR and plain image panoramas. However it suffers from a few drawbacks, which include difficult installation, browser plug-in conflicts and low popularity. The intent is to integrate the FreePV rendering code with VLC. This should not only automatically alleviate installation difficulty and plug-in conflicts, but also bring panorama viewing to a much larger audience. This project will initially focus on basic support for QTVR files and equirectangular images.

Detailed Description

The way I see it, based on rudimentary knowledge of the VLC internals, is that technically this project is about writing a codec to handle QTVR and an output module for viewing frames projected onto the inside of a rotatable OpenGL sphere.

My Commitment

I'm committed to work at least 40 hours per week for the duration of the GSoC on this project except for one week (to be determined) when I will be gone on vacation.

Collaboration with the FreePV dev team

Since this project was born out of an explicit idea[1] from the FreePV developers and because they promised it in a private e-mail I am certain that they are willing to help me in this project as best they can.
