{{Module|name=timeshift|type=Access filter|first_version=0.8.2|last_version=0.9.9|description=enable timeshifting on live streams}}

This access filter will enable timeshifting on live streams. The user will thus be able to pause the stream. Buffered data will be stored in memory for short periods and on the hard drive afterwards.

Sebastien:

== Introduction ==

{{VLC}} is a large and complex piece of software. It also uses a large number of [[Contrib Status|dependencies]].

Being open source allows VLC development to benefit from a large community of developers worldwide. However, entering a project such as {{VLC}} can be long and complex for new developers.

This '''guide''' seeks to help understanding the VLC code base and VLC internals to quickly get up to speed. 

''NB: this guide is '''not''' about compiling VLC.''

== The layers of VLC and libVLC ==

=== VLC's Core / libVLCcore ===

The most important (and probably most complex) part of VLC is the core, located in src/ in the repository.

== Introduction ==

Vlc have a very powerful "object variable" infrastructure useful for many things.

== Usage ==

var_Get will get the value if the variable exist (error overwise).

var_Inherit will get the default value or the one setted by the parent object.

var_CreateGet will create the variable and the get the default value if the variable wasn't already created. If the varible does exist before the call it will get the current value (and increment the refcount).

A variable must be created if you want to add a callback or change the value (with var_Set) of a variable
