The whole file or the samples of a track should be given to FreePV in order to build and display the panorama, thus there will be the need to analyze how we will display the panorama, probably we will have to modify some code on how VLC handle the images, then the the basic interaction with panoramas should be supported and it should be easy, since VLC already support some interaction with the DVD menus.

Latest revision as of 22:54, 8 July 2009

This project is part of Google Summer of Code 2009.
Student: León Moctezuma
Mentor: Antoine Cellerier

Project Abstract

FreePV is a panoramic viewer that was initially developed due to the lack of an implementation of QuickTime and Shockwave for Linux and VLC is a cross platform media player widely used, both work with QuickTime files and the problem arise from that, since both videos and VR contents share the same Mime Type this ends in a conflict for web explorers such as Firefox which should decide which plug-in to load based on the Mime Type of the file. To solve this problem the main goal of this project is to integrate the FreePV library into VLC to enable it to play QuickTime VR contents; the second goal would be to improve FreePV.

Previous works

The problem was identified during the realization of the Interactive Panoramic Viewer project proposed for SoC 2007. There was the Panorama Viewing proposal for SoC_2008 based in the same idea. There is also a page about this in the Panotools' Wiki.

Description

Since main proble is that both videos and VR contents share the same Mime Type this ends in a conflict for web explorers such as Firefox which should decide which plug-in to load based on the Mime Type of the file, thusthe first step of the project would be to distinguish between videos and VR contents, based on this I could create a demux and a decoder in VLC or use the existing functions inside FreePV, I would say that we should analysis this, since there are some decoders already implemented in VLC that would be useful. The whole file or the samples of a track should be given to FreePV in order to build and display the panorama, thus there will be the need to analyze how we will display the panorama, probably we will have to modify some code on how VLC handle the images, then the the basic interaction with panoramas should be supported and it should be easy, since VLC already support some interaction with the DVD menus.

The second part of the project would be the advanced interactive part by exploring the use of Wiimote, we will need to check which library out there will fit our needs to get advantage of the Wiimote's accelerometer, then we will experiment with the interaction with panoramas and finally using it to control other VLC's functionalities.

Main goal

  • Display Quicktime panoramas with VLC media player.

Project goals

  • VLC will be able to distinguish between video and vr content.
  • VLC will be able to display panoramas.
  • VLC should be able to handle the interaction required for panoramas.
  • Control VR with the Wiimote.
  • Control other media using Wiimote.
  • Keep improving FreePV.

Here is a tentative plan for the project, this schedule was the one submitted with the original project proposal, for a more accurate Schedule you can check this Google Calendar.

April 3th

I could start getting familiar with the VLC code, since April 3th, because I will have more than 2 free weeks and I should have plenty of time to do it, after April 22th I will be with exams and giving projects away, but I will try to keep working in the project.

Project Status

Project Accepted --Leonox 23:51, 20 April 2009 (CEST)

Git

You can checkout my repository by: 

 $ git clone git://git.videolan.org/vlc-leonox.git

If you want to test QTVR... 

 $ git checkout qtvr

to compile the qtvr decoder module you need to add the following argument: 

 $ --enable-qtvr

... or if you want to test the Wiimote 

 $ git checkout wiimote

to compile the wiimote control module you need to add the following argument: 

 $ --enable-wiimote
