VideoLAN has released version 2.1 of its popular open source video player, VLC. The update — codenamed “Ricewind” — brings new audio processing to the app, to improve both processing performance and audio fidelity. There is full support for surround sound outputs in addition to new effects and many new supported metadata formats for audio.

On the video side, the app has ported the OpenGL output to OpenGL ES, making ports to iOS and Android much easier. Notably, VideoLAN says that VLC is now ready for Ultra-HD content (otherwise known as 4K). The app update has also focused heavily on improving MKV compatibility, including better seek performance and subtitle metadata support.
