I think they can also appear in raw bitstream format, then of course lacking metadata (although I really like the thought of having a raw bitstream opus file with an ID3v2 header, as possible in Winamp e.g. with .aac files
Moreover, I've heard that the matroska container is also one of the possible file formats for opus.
MP4 container is technically possible but it ist not standardized from MPEG/ISO's side (yet - who knows....).
from what i've read up (only out of interest and not with a means to implement anything), there is a variation in the header which allows opus to be detected that way. though being in an OGG container is a down-side rather than a plus with things.
Also a "+1" for me for the wish of having a native in_opus.dll bundled with Winamp itself. Would be a great thing to advertise as it's the upcoming standard for HTML5 etc.
As it is also delivered in OGG container, there would have to be some mechanism to decide whether it is a vorbis or an opus file - maybe in_vorbis should also handle Opus then (and then be renamed to in_ogg or something like that). So no separate in_opus would be necessary.
To have OPUS natively as decoder and encoder would be really nice.
With in_dshow.dll I have a bad and heavy noise. All other dshow players sounds fine.
Thanks
According to the Hydrogenaudio listening tests, it outperforms current proprietary codecs @64kbps. I suspect that it does just as well at higher bitrates.
there's nothing stopping someone creating a plug-in to allow it to be supported... (as i'm not aware of any impetus to do this officially but i will heavily note that i could be wrong on what is or isn't planned). and the impression i get is this is trying to take over from Ogg Vorbis for the streaming side of things (not sure on where it's positioned for local files) which we know is used but pails into insignificance against the main streaming formats.
