352x288, 320x240
These two look like winners for testing with
The Harvard Digital Literacy Club found that Nicaraguan students were able
to sign to each other even at the pretty awful video quality produced by
the XO-1's Record activity. It wasn't ideal, but the signing was
comprehensible.
Yah, it's ok, but for long-term, sustained communication its pretty painful.
Could focus test as well, but I'm fluent and my wife is Deaf and my experience is
that
if there's a choice between the two, people would rather have a smaller window with
smoother signing.
Cropping the image would be interesting, as it requires much less CPU time
than scaling. You might want to experiment with using, say, just the
right half of the visual field, because the XO camera is off-center.
Also useful
You should benchmark this to see if the cost of converting YUY2->I420 is
offset by the increased encode speed.
Figure the team will give it a shot as well.
Thanks so much. This is extremely helpful!
