Hello experts

I am working on 360 degree video live HLS streaming. I am using nginx server, nginx-rtmp module and ffmpeg. I am using following command to transcode mp4 360 video to flv and push to rtmp port

sudo ffmpeg -i coaster.mp4 -vcodec libx264 -strict unofficial -vprofile high -acodec aac -f flv rtmp://localhost/stream/coaster


coaster.mp4 is 360 degree video, when I playback video from rtmp://localhost/stream/coaster, it plays like 2D video without 360 view. when I checked meta data then I found side
However If i use -strict unofficial as follows then out.mp4 file will be 360 degree with proper metadata.
sudo ffmpeg -i coaster.mp4 -vcodec libx264 -strict unofficial -vprofile high -acodec aac out.mp4

anykind of help suggestions would be highly appreciated.

Thanks
Rama
