The Decoder has no external check on the regions beyond ADV. One reference owes
nothing to their crate: each movie's own duration from its WMV. A start-truncated
stream must decode shorter than its movie -- ADV's was 38% short before the fix.
Dumped every region and decoded every chunk: 25 three-chunk regions, 75 chunks, 0
more than 5% short, largest deviation 1.78%. No region is still truncated, and
the reference is genuinely external.
Flags a population discrepancy: their page says 8 of 10 three-chunk regions start
mid-stream; I find 25 three-chunk regions on this disc. Reported, not resolved.
My first run reported '0 of 13' and there were 25 -- cargo run inside a while
read loop consumes stdin, so every second movie was eaten and the covered set was
positions 1,3,5,7... The result was correct for what it measured and the
population was half what the sentence implied. That is the truncated-log trap
arriving in my own shell loop; I caught it only by comparing against a count from
one command earlier.
