Subject: resindvd: Start with a larger subpicture queue for preroll.
X-Git-Tag: 1.19.3~507^2~14937
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=16f5120d96070a86c420fe7d8ddb27340b0d8b6c;p=platform%2Fupstream%2Fgstreamer.git

resindvd: Start with a larger subpicture queue for preroll.

Shrink the queue once we're prerolled. Fixes the Fringe S1
DVD. Also, ensure we only fire no_more_pads once.
