• Originally an academic project, it aims to solve cross-platform media playback and streaming problems.

Open Source and Growth:

• In 2001, VLC was released as open source software with a GPL license to attract contributions from developers around the world.
• In 2009, VLC 1.0.0 was released, marking its maturity and support for a wide range of media formats.

Important versions:

• VLC 2.0 (2012): Improved user interface, added Blu-ray playback and more efficient decoding.
• VLC 3.0 (2018): Supports hardware acceleration, 4K/8K, HDR, 360° video and Chromecast streaming.
• As of 2025: The latest version (3.x series or 4.0 beta) optimizes new formats such as AV1, VR support and user interface modernization.

Community driven:

• The VideoLAN organization is composed of volunteers, the code is hosted on GitLab, and it is continuously updated to adapt to new technologies and user needs.
