The OGG container format and the Vorbis and Theora codecs are included in the Windows Media Extensions package. This is included by default in in Windows 10 Insider Preview Build 17063.Thomas Ruecker (TBR) commented
Please pay attention to Ogg Chaining (Page 4 of RFC 3533). Most player implementations get that wrong initially.
Good testcases are:
- concatenate several files and check if the resulting single file can be played from beginning to end
- Go to http://dir.xiph.org and play an Ogg/Vorbis and an Opus stream that each must show "Artist - Title" info on that page. Chaining happens upon change of song, easiest visible in the changed Artist - Title. Verify that it continues playing as the song changes (the metadata will not change on the page though).
Please note that Icecast streams do NOT send a content length, as they are continuous streams of data. Seeking is not supported and content MUST NOT be cached. This is also valid for MP3 and AAC streams.
