MediaProbe's MIME table, its image-demuxer rule and its Int reader are pure
functions with no test at all, and each fails silently rather than loudly.
shortName falls through to substringAfter('/') and reports a plausible-looking
string that CodecNames may or may not still recognise, so a dropped arm turns a
stream-copyable file into a re-encode. isImageFormat is checked before anything
else in classify, so a wrong answer overrides both probes. intOr's runCatching
is the only thing standing between a Float frame rate and losing every other
track property the loop had read.
Widen the three to internal, as #57 did, and say in each KDoc why the shape is
what it is -- the _pipe suffix is not a substring test because yuv4mpegpipe is
raw video, and getInteger casts rather than coerces.
Every format name asserted came from ffprobe rather than from memory: a picked
.png reports png_pipe, a .jpg reports jpeg_pipe, a .y4m reports yuv4mpegpipe.
