Regarding videoconvert element, I found gst-base-plugin issue #614[1]
and its merge request !263[2]. I'll try the patch set in the merge
request. It might also solve the our issue though they aren't updated
for several months.
What do you think about implementing our own videoconvert element based
on the above patch?
