Hi Oliver. To my knowledge there's nothing special about muxing more than 2 channels of audio with a video stream. Once a video file and a multi-channel audio file are ready to mux, FFmpeg can do it (MP4Box is also useful for MP4 streams). About mixing codecs: there's cases where the MKV container is required; for example, H-264 + Opus, but I could be wrong. What I found difficult (3 years ago) was to prepare and render multi-channel audio streams and save them in the AMB format, but now I suppose there's more options.
I did not know about VLC3 and its ambisonics support. But I can see here: https://twitter.com/m4gsoft/status/890127816842465280 That the support is based on Google specs: https://github.com/google/spatial-media I guess that the produced files can also be decoded to speaker arrays. P.S.2: I'd be trilled to consult the FB page that Umashankar suggested, but it requires a login and I'll never get a FB account. So any useful info found on FB should be forwarded to non-big-brothered repositories. -- Marc Le Tue, 24 Oct 2017 12:03:02 +0100 Oliver Larkin <olilar...@googlemail.com> a écrit: > Hi All, > > Is anyone is aware of a good resource that will help me learn about > muxing video with ambisonic audio?
