Oggcodecs release 0.83.17220

Oggcodecs is a set of DirectShow filters for playing Ogg Vorbis, Speex,
Theora and FLAC files in Windows Media Player and other players.

This release has improved file and networking support, offered by 
default DirectShow filters. More bug fixes, particularly to Theora and 
FLAC, and updates for Internet Explorer's HTML5 <video> technical preview.

Changelog for Version 0.83.17220

* Updated libvorbis to version 1.3.1
* Updated libogg to version 1.2.0
* Ogg Demux filter has been changed from a source + parser filter to 
just parser filter. This step allows usage of DirectShow's "File Source 
(Async.)" filter which can handle files bigger than 2GB, or "File Source 
(URL)" which gives better networking support (proxy, ipv6, etc.)
* HTML5 <video> plug-in has received a couple of improvements:
   - URI support given by uriparser library
   - VMR9 support (instead of VMR7), this requires DirectX9
   - Internet Explorer Standards mode support, instead of just Quirks
   - width and height basic attribute support
* Removed OGM decoding support
* Fixed playback of Theora files with big ogg pages (e.g. hi-res "Patent 
* Fixed #1447: common http based ogg streams broken in Vista WMP 
(atleast vista 64)
* Fixed #1301: [OGGDSF] dsfOggDemux2.dll, fails for http with private ip
* Fixed #1657: FLAC 7.1 wrong mapped channels
