Subject: qv4l2: reset size after changing aspect ratios or scaling mode
X-Git-Tag: v4l-utils-1.3.90~126
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7b7fc920488991bd5776b351a2ac6ee2f58b3342;p=platform%2Fupstream%2Fv4l-utils.git

qv4l2: reset size after changing aspect ratios or scaling mode

When the video or pixel aspect ratio is changed by the user, or if
scaling is enabled/disabled, reset the window size to the optimal
size. This behavior is much more natural.
