A viewer for 360-degree and VR180 videos on Linux: drag to look around, wheel to zoom. A lightweight Linux alternative to 360-capable players such as KMPlayer.

What it really does:

• Re-projects equirectangular 360, stereo top-bottom/side-by-side, VR180 half-equirect, cubemap 3x2/6x1 and EAC sources with FFmpeg's v360 filter, using the camera yaw, pitch, roll and field of view you set.
• Output views: flat (rectilinear), little planet, fisheye, Pannini, cylindrical and equisolid.
• Source projection is auto-guessed from the video size and can be changed manually.
• Saves the current view as PNG and exports a flattened MP4 of the current camera (real FFmpeg encode with progress).
• Library tab scans your Videos, Downloads and removable media and shows resolution, codec and likely projection.
• Video only: this release has no audio output. The view updates when you release the mouse (FFmpeg re-renders it).
