Dash + Ambisonic

Postby NicolasNablaware » Tue Dec 05, 2017 2:07 pm

Hello,

I would like to know if it's possible to use Dash and Ambisonic in the same project, I need to livestream 360 Ambisonic Audio using MPEG-DASH, I was wondering if forgejs could handle that and if so how could I get it working ?

Thank you.

Edit : I just found this line : https://github.com/gopro/forgejs/blob/1 ... ia.js#L246 I think it means dash and ambisonic are incompatible inside ForgeJS ? Would be nice to have that highlighted somewhere because primary features of forgeJS right now are Dash and Ambisonic support.

The compatibility hasn't been applied yet.
Only HTML5 video are ambisonics compatible for the moment.
If you have an ambisonic DASH stream I can give a look on next days to see if it's possible easily.

HLS has been pushed for validation today on the repository. It will be more simple to do it with it because you deal directly with the HTML5 video object and not a third party MediaPlayer.

HLS support is great ! But I don't understand fully how it could help me to play ambisonic audio.

Here's some DASH stream with ambisonic audio from Google : https://yt-dash-mse-test.commondatastor ... 20416.html

If I had a clue how to make it work I could try on my own.


Thank you and your team for your awesome work, keep it up man !

Hi Nicolas,
I'll have a look on it asap.
In fact our HLS quick implementation based on hls.js is using the default HTMLVideoElement so it's more easier than the MediaPlayer of dash.js to access audio tracks.

Hey BBaudel,

Thank you for investigating my issue, I'll be happy to help if there's anything I can do.
I'll look into VideoHLS to see if I can plug Omnitone with the HMTLVideoElement.

Please keep me updated.

Sorry for the delay.
I was working on other products and I've not made any progress in this area.
