Subject: gstid3tag: Don't extract a track number unless present.
X-Git-Tag: 1.19.3~511^2~9634
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=35a9de28f425f80afaa195f13a74f0ba94cf3a6c;p=platform%2Fupstream%2Fgstreamer.git

gstid3tag: Don't extract a track number unless present.

In ID3v1, a track number is present only if byte 125 is null AND
byte 126 is non-null. If the track number is not present, don't add
a track number tag with value 0.
