Hi boys and girls, i've got a video with audio codec 0x6771 (Ogg Vorbis 3 PLUS) and no there sound only noises.....and i can't find anymore...you can help me? thank you.

I have never heard about that codec.

Only vorbis I (1) exists.
Vorbis II (2) has been on the planning stage for several years, but it hasn't received much development time (in favour of Theora video codec).

the "Plus", i guess it could mean something like SBR (like aacplus). There existed one codec named PLUS-V that could be added to other codecs and was similar to SBR.

That being said, the main developer of Vorbis said that SBR-like encodings wouldn't improve Vorbis much, since it already had a mechanism that provided a similar functionality.


Concluding: That either is a fake codec ( virus, whatever..) or a 3rd party experiment of someone.

oh my God......

Try to install Vorbis ACM Codec or CoreVorbis (if you are using DirectShow player), that should solve the problem.

Don't tell me some developer went ahead and forked PlusV into Vorbis!? How many times did Xiph say that PlusV was not well suited for the codec. You think they would have listened by now, but NO. It's the same thing with the OGM people. Blargh annoying.

No man...i was already installed all the ogg codesc that i know...ACM and CoreVorbis.....

No guarantees, not tried this myself, give it a good AV scan etc.

Describes as being an obsolete Vorbis ACM


Leads toward a possible better online source

Even mentions the 6771 tag.

Fast reply: could be an MP3+ into OGG container...

Stick the file into gspot and see what it says about it then report back here.

The VorbisACM(audio codec 0x6771 and others) does not guarantee compatibility between versions. You must choose an appropriate version.

It is not general-purpose codec for movie distribution.

I had the same issue with the noise instead of audio, this is one I use that worked:

OGG Vorbis 3 Plus

File will be there for next 7 days.
