Subject: basevideo: Add the caps to the GstVideoState and clean up caps/codec_data properly
X-Git-Tag: RELEASE-0.11.1~272^2~108
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=525875727aa91998c238fc13fe4477b60527741b;p=platform%2Fupstream%2Fgst-plugins-bad.git

basevideo: Add the caps to the GstVideoState and clean up caps/codec_data properly

Having access to the caps in ::set_format can be useful if
non-standard caps fields like the h264 alignment must be accessed.
