Subject: mp4: Remove useless casts in mp4ff_parse_tag().
X-Git-Tag: v0.7.1~7^2~120
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=e1a8c906d87d543961e021700240a2148c088fc4;p=paraslash.git

mp4: Remove useless casts in mp4ff_parse_tag().

These casts have no effect because "len" and the second argument of
mp4ff_read_string() are of type uint32_t.
