Moov atom not found in mp4 file rendered with Blender

I’ve tried to render a 360 degree animation video in blender.
Rendering got completed and the video is playable in mediaplayers like VLC.

For uploading in youtube as 360 degree video, I need to add additional tags to metadata,
Which I am trying using an script “spatial media injector” as recommended by google.

This process is fetting failed if I try to add meta data to any mp4 rendered using blender.
I have selected mpeg4 as preset as well as codec.

Please help me on this.I am not getting what I have missed.

Thanks
