Subject: oggstream: Add a default GstOggMap
X-Git-Tag: 1.16.2~1040
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c3006b17d1b927184197564b279ebb53bd9a650b;p=platform%2Fupstream%2Fgst-plugins-base.git

oggstream: Add a default GstOggMap

Since the default value of a GstOggPad.map.map was 0 ... we would
end up using wrong functions from mappers() if the stream wasn't
initialized yet.

Instead of that, use a default blank/empty first entry.
