// Lightfield Bitstream Parsing
// ============================
//
// This is a lightfield bitstream parsing example. It takes an input file
// containing the whole compressed lightfield bitstream(ivf file) and a text
// file containing a stream of tiles to decode and then constructs and outputs
// a new bitstream that can be decoded by an AV1 decoder. The output bitstream
// contains reference frames(i.e. anchor frames), camera frame header, and
// tile list OBUs. num_references is the number of anchor frames coded at the
// beginning of the light field file.  After running the lightfield encoder,
// run lightfield bitstream parsing:
// examples/lightfield_bitstream_parsing vase10x10.ivf vase_tile_list.ivf 4
//   tile_list.txt
//
// The tile_list.txt is expected to be of the form:
// Frame <frame_index0>
// <image_index0> <anchor_index0> <tile_col0> <tile_row0>//   uint8_t tile_row;
//   uint8_t tile_col;

// } TILE_LIST_ENTRY;
