More GDV Documentation

November 23rd, 2005 by Multimedia Mike

I have written some more documentation for the GDV file format. VAG’s decoding functions are pretty straightforward but the documentation process gets tedious in a hurry. The more advanced coding methods use a bizarre bit packing method interleaved with data bytes that I can almost guarantee FFmpeg does not support with its native bitstream readers.

I have the game Realms Of The Haunting which is 4 CD-ROMs packed full of FMV goodness using the GDV format. Two other games, Hardwar and Normality, are known to use the GDV format, but with other color depths and perhaps other coding modes. If anyone has those games, I would like to see some GDV samples from each.
