SoC 2008/Enhance PVR capabilities of VLC

This project is part of Google Summer of Code 2008. Student: Dylan Yudaken Mentor: Pierre d'Herbemont

Intro

This is the page I will use to document the progress of my Summer of Code 2008 project. Feel free to send me ideas, comments or any inspiration.

Project Abstract

VLC has fast become one of the most common video players available for 'non-technical' users. The ability to watch streams easily and efficiently is a huge advantage for VLC. The ability to timeshift streams has been added to the latest unstable builds, however it is vastly underfeatured and not nearly ready for release. The features would enhance VLC to a new level which would allow a new set of users to use it.

I propose to extend & improve the PVR capabilities of VLC. The current version is severely lacking in functionality and performance. There is a very basic timeshift capability already. To this I will add the ability to randomly seek through the buffer (fast forward, rewind, etc ). The ability to save buffers and continue recording to the new file will be added. These recordings will be in any chosen format. These features will help anyone who uses VLC to watch TV shows to easily turn their client into a MythTV/Media Centre style client. I will tie the module in with the user interface properly so that the state of the buffer and the current position can be easily seen. I then plan to begin work on a framework that combines all of these features into a simple interface easily accessible with a remote control. The interface will combine VLM and the media library into a single easily accesible place. The interface will have the ability to 'talk' to the server sending commands such as changing tv channel or switching input source.

With this and the completion of VLM and the playlist managing system VLC will have the capabilities to become a fully featured PVR system with the massive advantage of it being run off a streaming server if need be.

Current Status

Currently in preparation for the beginning of the program. Busy getting a good plan built.

Details

The plan is to work on two parts.

Timeshift Module

Initially the timeshift access module will be improved considerably. Bugs ironed out and additional functionality added. This should be a relatively quick thing to do, hopefully being done in the first 2-3 weeks.

PVR Interface

Then a new interface will be added. My current idea (still to be discussed with more knowledgable developers) is to build onto the QT interface. A newwidget will be created that contains the PVR-style menus. These will be nice and big for use on a tv. There will be screens to access music & videos (from the library still to be finished), streams, options, pictures & VLM. There will potentially also be a new sort of hotkeys interface specifically for the PVR, so that you can have specific hotkeys linked to a remote control when watching fullscreen.

Project Timeline

Time constraints

Studying in South Africa I will have exams at the end of May. Specifically the week beginning 26 May I will not be able to do any work with some very difficult exams. Also being in South Africa, 3 times in every 2 weeks there are scheduled power cuts for 4 hours. During these times there will be no coding either. :)

Timeline

This will be expanded upon, specifically the PVR Interface section will be much more detailed closer to the time, when a specific plan is developed.
