Subject: [PATCH] plugin: Set initial display resolution to 1x1

We do not support zero width/height (described in our caps). Set initial video
dimensions to 1x1. They are going to be updated on first buffer after video info is set.

This avoids running into https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1139
and makes sure we do not do any divisions by zero here either.
