Thanks for the bug report and the sample file.

This should fix it:

commit 61fa4c7bb2295f29d38daceffdfaca3a8eb2216a
Author: Tim-Philipp Müller <tim at centricular.com>

    typefindfunctions: lower H.263 typefinder max probability

    The typefinder returns LIKELY for as little as one possible
    sync and no bad sync (not even taking into account how much
    data was looked at for that). It's generally just not fit
    for purpose, so should just not return anything like LIKELY
    at all ever, even more so since it only recognises one out
    of ten H263 files, and likes to mis-detect mp3s as H263.
