If I use the CyberLink ActionDirector (that's bundled with the Samsung Gear 360 camera) to convert the videos to equirectangular, then import these to Vegas Pro, the audio track will not work - no audio track is imported for the video.
If I play back these video files in VLC or such, I can hear the audio, and FFMpeg detects an AAC (LC) (MP4A / 0X6134706D) 48k stereo 128kbps audio track, but Vegas just fails to import them for some reason.
However, if I stitch the videos with my Galaxy S7 phone's Gear 360 app, the audio track works in Vegas too.
What's going on here? Is that audio format not supported by Vegas?
