This is cool!

Please can anyone tell me how I can get VLC to
feed 4.0 or 5.1 or whatever ambisonic sound
format is available from this video -- ideally
directly to my RME UFX (through the "speakers"
option in the Windows applet)? Alternatively, B
format. All I can get at present is stereo.

If VLC is the problem (although I can play my
surround audio files with it), what DOES work?

Thanks,

David

Since when? They are not in VLC v3.0.4 which claims to be current, nor
does the VLC wiki contain the word Ambisonic.

Bruce's posting reminded me to upgrade VLC to 3.0.4.

It says here https://www.videolan.org/vlc/releases/3.0.0.html : "VLC
supports 360 video and 3D audio, up to Ambisonics 3rd order"

In the basic installation, there is an "Ambisonics renderer and
binauralizer" plugin listed under "Tools/Plugins and extensions". I
dont know whether it needs some action to install it, but in any
case, I am not interested in Binaural.

In April 2014 (how time flies!), when I was putting some test 4.0
multichannel .mp4 files on my website, I feel sure that I had them
play back locally through VLC, but I could be mistaken, and I cant
recall how I might have done it.

My reading is that the renderer works on its own, and the binauraliser
is separate. However, I can find no clue how to invoke it; when I
offered it a .amb file, the codec information claimed it had three
front channels and one LFE! And how does it decide otherwise what
convention the file is made to?

In Windows, the key is to have configured the audio device (default, or
whichever is selected in VLC) in Control Panel/Sounds to have the right
number of channels - then VLC (and any browser) will play 4.0 or 5.1
files appropriately for the number of speakers you have. I have
hundreds of 4.0 files on my web site (behind a password, sorry)*, and
they simply play as required. It does require the driver to have the
Windows multi-channel mode implemented though - so MOTU interfaces
don't work, because they haven't bothered (I've been using VB-Audio's
ASIO Bridge to get around this, though its setup is far from intuitive).

I presume it is being rendered as a binaural sound track for headphones
- certainly the audio image moves around when you rotate the displayed
image in the browser window. I imagine this is being done at YouTube
in response to the browser passing back the required panning position.
