I want to start making more 180* / 360* animations with Blender. I recently read that VLC is among the first video players to properly support panoramic video, it’s one I use so that’s great news on the matter.
Only problem is I was told such videos must be encoded with special metadata baked into them, indicating it’s a sphere mapped video and what sort. It was suggested using special software to set this data, which is an extra dependency I’d like to avoid as I prefer using just Blender to produce the frames then ffmpeg to compile them. I understand I need to include specific properties like the FOV of the video, something I assume I can fetch from the settings of my camera in Blender and pipe into the appropriate video tags.
Can anyone list the metadata tags I need to set on panoramic and / or stereoscopic clips for video players to recognize them accordingly? Then how do I set them either in ffmpeg, from Blender if they can be baked into exr images at render time, VLC if it allows writing that information to a video, or at least a shell script for Linux which I’m familiar with and could easily use? I alternate between mp4 and ogv for video format if they’re relevant.
