Subject: avidemux: add convert query, fix duration query
X-Git-Tag: RELEASE-0.10.15~313
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3e7aede3ea4a0078dbbbf09b22eb762e5eda404b;p=platform%2Fupstream%2Fgst-plugins-good.git

avidemux: add convert query, fix duration query

Fix the duration query so that it also works with formats other than
TIME, such as DEFAULT to get the number of frames.

Add a convert function.

Fixes #578052.
