VLC has been updated to version 2.0.4 and the modifications touch on plenty of components, from codecs and demuxers to audio output and Qt framework.
In the case of audio output, the playback synchronization with PulseAudio has been improved and there are several repairs referring to live audio device selection and audio output behavior when the output device is plugged or unplugged during playback on Mac OS X.
On Windows, the fix refers to the detection of some 5.1 and 7.1 kits.
In the case of demuxers, the fixes deal with eliminating the problems with Vimeo, Koreus and YouTube Lua parsers and now there is support for YouTube live streams.
The wallpaper mode on Windows 7 and 8 has also been mended and should work with no problems.
