  24  * VQA Video Decoder by Mike Melanson (melanson@pcisys.net)
  25  * For more information about the VQA format, visit:
  26  *   http://wiki.multimedia.cx/index.php?title=VQA
  27  *
  28  * The VQA video decoder outputs PAL8 or RGB555 colorspace data, depending
  29  * on the type of data in the file.
  30  *
  31  * This decoder needs the 42-byte VQHD header from the beginning
  32  * of the VQA file passed through the extradata field. The VQHD header
  33  * is laid out as:
  34  *
  35  *   bytes 0-3   chunk fourcc: 'VQHD'
  36  *   bytes 4-7   chunk size in big-endian format, should be 0x0000002A
  37  *   bytes 8-49  VQHD chunk data
  38  *
  39  * Bytes 8-49 are what this decoder expects to see.
  40  *
  41  * Briefly, VQA is a vector quantized animation format that operates in a
  42  * VGA palettized colorspace. It operates on pixel vectors (blocks)
  43  * of either 4x2 or 4x4 in size. Compressed VQA chunks can contain vector
  44  * codebooks, palette information, and code maps for rendering vectors onto
  45  * frames. Any of these components can also be compressed with a run-length
  46  * encoding (RLE) algorithm commonly referred to as "format80".
  47  *
  48  * VQA takes a novel approach to rate control. Each group of n frames
  49  * (usually, n = 8) relies on a different vector codebook. Rather than
  50  * transporting an entire codebook every 8th frame, the new codebook is
  51  * broken up into 8 pieces and sent along with the compressed video chunks
  52  * for each of the 8 frames preceding the 8 frames which require the
  53  * codebook. A full codebook is also sent on the very first frame of a
  54  * file. This is an interesting technique, although it makes random file
  55  * seeking difficult despite the fact that the frames are all intracoded.
  56  *
  57  * V1,2 VQA uses 12-bit codebook indices. If the 12-bit indices were
  58  * packed into bytes and then RLE compressed, bytewise, the results would
  59  * be poor. That is why the coding method divides each index into 2 parts,
  60  * the top 4 bits and the bottom 8 bits, then RL encodes the 4-bit pieces
  61  * together and the 8-bit pieces together. If most of the vectors are
  62  * clustered into one group of 256 vectors, most of the 4-bit index pieces
  63  * should be the same.
