We will keep this thread posted once we hear back from the team. They are still working on getting the 360 audio accessible in both the GoPro MAX Player and the GoPro MAX Exporter. Thank you for your patience.

VLC recognises both audio streams in the .360 files from the SD card as 32 bit signed little endian and plays them back as such

 

I figured installing ffmpeg on my machine would allow me to import them using Audacity

 

Unfortunately I am wrong and the 4 channels simply come up blank (with some background noise)

 

So, how come VLC can see it and ffmpeg can't

 

Kinda need to solve this ASAP or I need my money back

 

Thanks

Okay it's late I am trying everything to make this work and I made a mistake in my last post

 

Here's whats really happening

 

Handbrake (using ffmpeg library) thinks the files in PCM_S32LE

 

VLC plays the file back and thinks it is PCM_S32BE

 

Audacity recognises the file as BE and imports silence

 

I suspect the file is carrying the wrong flag and VLC somehow works out the file is actually Big Endian?

 

I suspect your YouTube issue is down to the wrong flag in your files BE vs LE

 

Need to get this fixed ASAP

..just checked is as well...

i am able since a month now to extract the 4ch ambisonicstrack with ffmpeg.

That files can be used without problems for example in resolve and premierepro.

Playing back in vlc shows me PCM S32LE (no BE)  (little endian because I'm on a mac) ... so this way should work

 

... but for sure ... it should work automatically with the gopro software as well ... what is not happening since nearly 2 month now ... and I really cannot understand what is going on at gopro... if someone like me can extract and combine this audiotrack from *.360 to *.mp4 then why in the world are the gopro developers are not able to provide this as well ????
