Subject: vorbisdec: don't put invalid bitrate values into the taglist
X-Git-Tag: 1.19.3~511^2~9588
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=20fb58be198e7d76ece4e6c635cda7c919fad6d2;p=platform%2Fupstream%2Fgstreamer.git

vorbisdec: don't put invalid bitrate values into the taglist

Bitrates are stored as 32-bit signed integers in the vorbis
identification headers, but seem to be read incorrectly,
namely as unsigned 32-bit integers, into the vorbis structure
members which are of type long, which makes our check for
values <= 0 fail with files that put -1 in there for unset
values.
