|

// This is an example of a simple lightfield decoder. It builds upon the
|
||||
// simple_decoder.c example. It takes an input file containing the compressed
|
||||
// data (in webm format), treating it as a lightfield instead of a video and
|
||||
// data (in ivf format), treating it as a lightfield instead of a video and
|
||||
// will decode a single lightfield tile. The lf_width and lf_height arguments
|
||||
// are the number of lightfield images in each dimension. The tile to decode
|
||||
// is specified by the tile_u, tile_v, tile_s, tile_t arguments. The tile_u,
|
||||
// tile_v specify the image and tile_s, tile_t specify the tile in the image.
|
||||
// After running the lightfield encoder, run lightfield decoder to decode a
|
||||
// single tile:
