Subject: mp4: Remove two local unused header_size variables.
X-Git-Tag: v0.7.1~7^2~43
X-Git-Url: http://git.tuebingen.mpg.de/?a=commitdiff_plain;h=cc12c978b4ad5ed927747fbc7e4cf3289b9da15b;p=paraslash.git

mp4: Remove two local unused header_size variables.

The header size is an optional pointer argument of atom_read_header(),
i.e., callers may pass NULL if they aren't interested in the atom
header size.
