Questions tagged [vlc]

VLC is a free and open source cross-platform multimedia player and framework that plays most multimedia files as well as DVD, Audio CD, VCD, and various streaming protocols. Use this tag only for programming-related questions about VLC.

See VLC (Video LAN) Media Player for more details.

Stack Overflow questions tagged VLC may have to do with:

  • Compiling VLC media player's source code and its underlying frameworks
  • Using VLC's underlying libraries (libvlc, VLCKit) inside your own programs
  • Scripting/automating VLC media player via a Bash script, Lua or other approaches
  • Controlling VLC media player via the command line and questions concerning the usage of available parameters
  • Encoding, transcoding or streaming through VLC media player's interfaces via scripts, command line or provided frameworks

Questions about LibVLC, the external programming interface for VLC Media player, should be tagged as well.

If your question is about the usage of the player (with no programming involved) ask your question at Super User and use their vlc tag
