Sorry, my response was clearly incomplete. GstVideoFrame and
gst_video_frame_copy() will allow to copy from one stride to another. Just
create a frame with "normal" stride, and copy to it as a slow-path fallback. We
shouldn't care much about performance, writing raw to filesink is only useful
for testing.
