Detailed Description

PSX STR file demuxer by Mike Melanson (melan.nosp@m.son@.nosp@m.pcisy.nosp@m.s.ne.nosp@m.t) This module handles streams that have been ripped from Sony Playstation CD games. This demuxer can handle either raw STR files (which are just concatenations of raw compact disc sectors) or STR files with 0x2C-byte RIFF headers, followed by CD sectors.
