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 the first week in April when I will be busy with final exams, and another 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.
Plan
This plan is based on the dates in the GSoC 2008 timeline
- March 31 - week 1
- write e-mails to the hugin and vlc-devel mailing lists asking for suggestions/ideas
- April 7 - week 2
- study for exams and finish school assignments
- write a patch for VLC
- April 14 - week 3
- April 21 - week 4
- figure out the interaction requirements for panorama viewing and how this will affect VLC as a whole
- decide (along with other developers) whether FreePV can be turned into a stand-alone, separately developed library that can be used by VLC to display panoramas
- think about how panorama viewing fits in with VLC. It should act as a codec for QTVR files, but it should also be able to use any 2d images/frames for panoramas (act as an output module?).
- make a list of QTVR functionality present in FreePV - aim to replicate this list in VLC
- identify which parts of FreePV can be used as a VLC module
- April 28 - week 5
- learn to write a codec/demuxer module
- write a plant of what will need to be changed/added in/to VLC
- by now I should have a good idea of how things fit together
- May 5 - week 6
- get an understanding of the QTVR format (possible start: http://developer.apple.com/documentation/QuickTime/InsideQT_QTVR/6Chap/chapter_6_section_1.html and the FreePV code)
- May 12 - week 7
- May 19 - week 8
- May 26 - week 9 - Students begin coding for their GSoC projects;
- June 2 - week 10
- June 9 - week 11
- June 16 - week 12
- June 23 - week 13
- libfreepv should exist and be usable in VLC
- June 30 - week 14
- simple QTVRs should be viewable by now
- July 7 - week 15
- July 14 - week 16 - Mid-term evaluations deadline;
- July 21 - week 17
- should be able to view image (.PNG, .JPG,...) panoramas
- July 28 - week 18
- should support a number of different projections and do everything that FreePV can with QTVR
- August 4 - week 19
- August 11 - week 20
- August 18
Module Options
- type of panorama: equirectangular,cylindrical,littleplanet,cubic...
- default FOV aka zoom
