12// Lightfield Encoder
13// ==================
14//
15// This is an example of a simple lightfield encoder. It builds upon the
16// twopass_encoder.c example. It takes an input file in YV12 format,
17// treating it as a planar lightfield instead of a video. The img_width
18// and img_height arguments are the dimensions of the lightfield images,
19// while the lf_width and lf_height arguments are the number of
20// lightfield images in each dimension. The lf_blocksize determines the
21// number of reference images used for MCP. For example, 5 means that there
22// is a reference image for every 5x5 lightfield image block. All images
23// within a block will use the center image in that block as the reference
24// image for MCP.
25// Run "make test" to download lightfield test data: vase10x10.yuv.
26// Run lightfield encoder to encode whole lightfield:
27// examples/lightfield_encoder 1024 1024 vase10x10.yuv vase10x10.ivf 10 10 5
28
29// Note: In bitstream.c and encoder.c, define EXT_TILE_DEBUG as 1 will print
30// out the uncompressed header and the frame contexts, which can be used to
31// test the bit exactness of the headers and the frame contexts for large scale
32// tile coded frames.
