Comment:

 Each chunk starts with a four byte identifier, followed by the size of the
 chunk (eight bytes).
 The whole file is the "{{{QMV }}}" chunk, audio and video is identified by
 {{{STRM}}} chunks, followed by the (large) "{{{DAT }}}" chunk, the
 {{{INDX}}} chunk near the end of the file and finally the {{{INFO}}}
 chunk.
 The absolute positions of the "{{{DAT }}}" and the {{{INDX}}} chunk are
 written before the first {{{STRM}}} chunk.
 Maybe the first {{{STRM}}} chunk starts always at 0x56.
