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.
