<blockquote type="cite"><div class="plaintext" style="white-space: pre-wrap;">I note a video artifact under certain conditions when watching any HD recording. The artifact is either absent or too difficult to notice when viewing SD recordings. Further, the artifact is only noticeable in HD recordings in certain instances: I note it when, for example, the camera is panning up or down or side-to-side, or when the frame includes a lot of movement toward the top of the screen. The artifact can be described as a series of horizontal lines that seem to get out of sequence about one quarter of the distance from the top of the screen. Once the panning or movement stops, the horizontal lines are gone and the display returns to normal--the artifact only showing up again once this panning or movement begins again. All in all the artifact shows up only very briefly and sporadically.
So, what is the artifact? I'm not much of a video connoisseur, so it just constitutes a minor annoyance for me: I can live with it. But if there is some simple way of fixing it, I might give that a try.
PS I had to compile MythTV without vaapi support since, on this machine, compilation errors out if I don't disable it. Perhaps the fact that I don't have vaapi support compiled in is resulting in my installation have less-than-optimal video output?
