having `set_category()` + `set_subcategory()` pairs of calls to setup the
location in the preferences tree where a plugin node needs to be attached
to, with corresponding pairs of option records in the plugin option sets,
is silly, inefficient and bug prone. all we need is the subcat records
and we can look up the corresponding cat from the data table when it
comes to time to build the tree.

here we take a step forward to address this, adding cat data to the subcat
data table, and a lookup function making use of it.

note, qt and macos tree construction are done a little differently from
each other, so while the change here is entirely sufficient to rid the core
option set of category hints as far as the macos code is concerned, more
work in a subsequent commit will be needed for qt. thus the purge of
`set_category()` must be postponed for a later commit and so for now we
must just ignore those records.

a subcat table entry was added for `SUBCAT_HIDDEN` since for now the qt
code could potentially look this up and we should preserve the existing
behaviour for it for now.

VLC media player

VLC is a libre and open source media player and multimedia engine, focused on playing everything, and running everywhere.

VLC can play most multimedia files, discs, streams, devices and is also able to convert, encode, stream and manipulate streams into numerous formats.

VLC is used by many over the world, on numerous platforms, for very different use cases.

The engine of VLC can be embedded into 3rd party applications, and is called libVLC.

VLC is part of the VideoLAN project and is developed and supported by a community of volunteers.

The VideoLAN project was started at the university École Centrale Paris who relicensed VLC under the GPLv2 license in February 2001. Since then, VLC has been downloaded billions of times.

License

VLC is released under the GPLv2 (or later) license. On some platforms, it is de facto GPLv3, because of the licenses of dependencies.

libVLC, the engine is released under the LGPLv2 (or later) license.
This allows embedding the engine in 3rd party applications, while letting them to be licensed under other licenses.

Platforms

VLC is available for the following platforms:

  • Windows (from 7 and later, including UWP platforms and all versions of Windows 10)
  • macOS (10.10 and later)
  • GNU/Linux and affiliated
  • *BSD and affiliated
  • Android (4.2 and later), including Android TV and Android Auto
  • iOS (9 and later), including AppleTV and iPadOS
  • Haiku, OS/2 and a few others.

Not all platforms receive the same amount of care, due to our limited resources.

Nota Bene: The Android app and the iOS app are located in different repositories than the main one.

Contributing & Community

VLC is maintained by a community of people, and VideoLAN is not paying any of them.
The community is composed of developers, helpers, maintainers, designers and writers that want this open source project to thrive.

The main development of VLC is done in the C language, but this repository also contains plenty of C++, Obj-C, asm and Rust.

Other repositories linked to vlc are done in languages including Kotlin/Java (Android), Swift (iOS), and C# (libVLCSharp).

We need help with the following tasks:

  • coding
  • packaging for Windows, macOS and Linux distributions
  • technical writing for the documentation
  • design
  • support
  • community management and communication.

Please contribute :)

We are on IRC. You can find us on the #videolan channel on Libera.chat.

Contributions

Contributions are now done through Merge Requests on our GitLab repository.

CI and discussions should be resolved before a Merge Request can be merged.

libVLC

libVLC is an embeddable engine for 3rd party applications and frameworks.

It runs on the same platforms as VLC (and sometimes on more) and can provide playback, streaming and converting of multimedia files and streams.

libVLC has numerous bindings for other languages, like C++, Python and C#.
