// 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> // <image_index1> <anchor_index1> <tile_col1> <tile_row1> // ... // Frame <frame_index1) // ... // // The "Frame" markers indicate a new render frame and thus a new tile list // will be started and the old one flushed. The image_indexN, anchor_indexN, // tile_colN, and tile_rowN identify an individual tile to be decoded and // to use anchor_indexN anchor image for MCP.
