Support for Google's VR180 file format (Daydream camera)?

[poVoq]

The readme mentions VR180, but I don't think this is actually the VR180 file format developed by Google & Lenovo for the Daydream Camera?

I think it includes some gyro sensor readings to allow the video-player to stabilize the recorded video in real-time.

Since Google has more or less abandoned this line of hardware, it would be nice to have some open-source tool support it. The camera itself is still really nice, but there is no way to play the videos properly on Linux.

Thanks!

The mentioned VR180 simply mean 180° equirectangular projection. The underlying file format is still a common image or video file.

Your linked site mentiones neither VR180 nor Daydream. A quick google search revealed nothing substantial. I found some references to VR180 creator, but that program seems to have vanished from the internet.

If you can point me to a specification of the file format, I'll look into it.

Sorry, indeed the info is a bit sparse even though it is less than 5 years old. Here are some links that might help:

Thanks for that. It's nice to finally find some spec.
You're right, it currently doesn't support VR180. I updated the README to reflect that.
Reading metadata is a bit tricky (especially when it's an additional stream channel), since neither the godot video player nor the encoder plugin support that, so I would have to write my own plugin. I do plan on eventually doing that (to support hardware acceleration if nothing else), but it will take a while.
