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.
