VrJpeg

.NET Helper library for *.vr.jpg files. These files are produced by the Google Cardboard Camera Android app.

Code samples:

• High level abstraction: create a full equirectangular stereo-panorama with poles filled in.

bool fillPoles = true;
int maxWidth = 8192;
Bitmap stereoPano = VrJpegHelper.CreateStereoEquirectangular(input, EyeImageGeometry.OverUnder, fillPoles, maxWidth);
stereoPano.save("stereopano.png");

• Mid level abstraction: extract the right-eye from the metadata, then convert it to an equirectangular image.

var xmpDirectories = VrJpegMetadataReader.ReadMetadata(input);
GPanorama pano = new GPanorama(xmpDirectories.ToList());

Bitmap right = VrJpegHelper.ExtractRightEye(pano);
Bitmap rightEquir = VrJpegHelper.Equirectangularize(right, pano);
rightEquir.save("right-equir.png");

• Low level abstraction: extract right-eye JPEG bytes and audio MP4 bytes directly from the metadata.

var xmpDirectories = VrJpegMetadataReader.ReadMetadata(input);
GPanorama pano = new GPanorama(xmpDirectories.ToList());

File.WriteAllBytes("right-eye.jpg", pano.ImageData);
File.WriteAllBytes("audio.mp4", pano.AudioData);
