Re: [PATCH v9 0/3] MR8034: winegstreamer: Call wg_format_get_max_size() to get the video decoder output sample size.

> The `fill_planes()` helper in `gst-plugins-base/gst-libs/gst/video/video-info.c` called from `gst_video_info_align_full()` sets the minimum alignment. Apparently, setting an alignment manually in `GstVideoInfo` can only increase it.

That's true, but I haven't found anything to indicate that we can't set the stride members of GstVideoInfo manually. I haven't found anything in the base video library, or several decoders, that seems to care about "minimum" alignment, and I don't really know why it would.

Because we implement stride by actually adding padding instead. That's arguably not very correct, but maybe there was a reason I've forgotten.
