YouTube Unsupported File Type

[M2Dr2]

I keep getting my 360 video and spatial audio file rejected by YouTube when trying to upload. I have used the following code when working with ffmpeg:

ffmpeg -loop 1 -i R0010183.jpg -i Location1B.wav -map 1:a -map 0:v -c:a copy -channel_layout quad -c:v libx264 -vf scale=iw:ih*1.125 -pix_fmt yuv420p -b:v 40000k -bufsize 40000k -shortest Location1.mov

The image was taken with a Ricoh Theta camera and i've ensured my audio is set to ambiX ACN/SN3D format. I've injected the metadata using the Spatial Media Metadata Injector:

Saved file settings Track 0 Ambisonic Type: periphonic Ambisonic Order: 1 Ambisonic Channel Ordering: ACN Ambisonic Normalization: SN3D Number of Channels: 4 Channel Map: [0, 1, 2, 3] Track 1 Spherical = true Stitched = true StitchingSoftware = Spherical Metadata Tool ProjectionType = equirectangular

The frustrating thing is that a colleague of mine has had success using the same files and the same process. I am now at a loss as to how to solve the issue.

I would appreciate any advice or comments, Mark

Hey Mark,

The issue here is the channel_layout flag passed to ffmpeg; for upload to YouTube, your file's audio must use the 4.0 channel layout (or be unspecified). So your ffmpeg command line should be:

ffmpeg -loop 1 -i R0010183.jpg -i Location1B.wav -map 1:a -map 0:v -c:a copy -channel_layout 4.0 -c:v libx264 -vf scale=iw:ih*1.125 -pix_fmt yuv420p -b:v 40000k -bufsize 40000k -shortest Location1.mov

Could you share where you got your ffmpeg command line from, if you got it from somewhere online? We'd like to make sure the source is fixed too. :)

Thanks, Dillon

Think Mark got it from http://www.brucewiggins.co.uk/?p=666

I'll happily update my page..... Funny thing is, it's always worked for me (with or without quad or 4.0 flags).

Cheers

Bruce

Ahhh, thanks Bruce! :) That would be great.

quad channel layout should not work on YouTube if it's specified, though it may have at one point; it will work in Jump Inspector though. YouTube only allows (i.e., succeeds in processing) ambisonic audio with unspecified or 4.0 channel layout.

Thanks for the clarification.... I'll update my page 😊
