Facebook Filter for 360° Videos

As you may know Facebook open sourced its ffmpeg filter to convert 360° videos. The source code is available on GitHub and has to be compiled into ffmpeg. This is quite a hassle if you just want to a quick check of the tools capability.

To save you some trouble I converted a test video in every available output layout. Kudos to Finwe for releasing their 360° test images and videos and giving me permission to publish the transformed images.

I converted the equirectangular input video with following command:

ffmpeg -i Orion360_test_video_2048x1024.mp4 -vcodec rawvideo -vf transform=input_stereo_format=MONO:cube_edge_length=512:output_layout=cubemap out.avi

Some of the videos got distorted but I think setting the width and height parameters should solve this issue.

I uploaded a stereo (top/bottom) version too. As far as I can tell the filter is just stacking both eyes on top of each other. I had to downscale some of the stereo images because of their file size.
