Subject: mov: do not overwrite timebase with sample rate
X-Git-Url: https://git.nihav.org/?a=commitdiff_plain;h=de3f3f006ff7b0b6407111d4dca3ec124be398fb;p=nihav.git

mov: do not overwrite timebase with sample rate

E.g. in AAC SBR case we may get timebase 2048/44100 with the nominal
sample rate being 22050 Hz.
