I'm still getting an intermediate frame. By intermediate, I mean that
the frame is essentially black with some area filled with the real
content. The 2 or 3 successive frames are "similar" and then I reach a
frame with the whole window updated.
My understanding was that GST_SEEK_FLAG_KEY_UNIT ensures that I reach a
"full content" frame. Am I doing something wrong or am I
misunderstanding the documentation? How can I avoid this?
