Hi all,
I've prepared a presentation for the upcoming workshop based on my RFC and the
comments I received.
It is available here:

Attendees of the workshop: please review this before the workshop starts. I
want to go through this list fairly quickly (particularly slides 1-14) so we
can have more time for other topics.
A note on the Pixel Aspect Ratio from me, since I won't be attending:
I'm not sure if having a VIDIOC_G_PIXELASPECT is enough, it will work
to get the current mode, but not for enumerating. Also it will not
work with TRY_FMT, that is one cannot find out the actual pixelaspect
until after a S_FMT. As mentioned in previous mail I think at a minimum
the results of ENUM_FRAMESIZES should contain the pixel aspect per framesize,
there is enough reserved space in the relevant structs to make this happen
Regards,
Hans
