Introduction
VLC media player is a large and complex piece of software. It also uses a large number of dependencies.
Being open source allows VLC development to benefit from a large community of developers worldwide.
However, entering a project such as VLC media player 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.
A very good introduction to VLC can also be found on enjoythearchitecture.
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 to the core This is a MUST-READ for developers.
- VLC modules loading
- Input (slightly outdated)
- VLC Object Management
- VLC variables
- VLM Internals
Plugins / Modules
Input
- Access
- An access module provides a byte stream from a location string MRL.
- Demuxer
- A demux module parses a byte stream and splits it into elementary streams (tracks).
- Access-Demuxer
- Also access_demux module combine the functionality access and demux (and bypass any stream filters), splitting elementary streams directly from a location string. It's used where the bytestream abstraction is inadequate.
- Stream filter
- A stream filter module converts a byte stream into another byte stream. It could be used for file or byte stream decryption, as it is already used for decompression (gzip, Bzip2, XZ).
- Decoder
- A decoder takes an elementary stream and convert into raw video, audio or text data, reading for output.
