[H-GEN] debconf video stack

[matt]

Dvswitch is no longer under development. Doesn't mean that it isn't 
still being used or is useful. Take Pycon for example.

We could have gone with gst-switch (dvswitch's evil gstreamer daughter 
;-) ) and that may have worked well but it would have meant time taken 
to get Eventstreamr (backend control program) to work with it. Time we 
didn't have since we spent a lot on being sick and the editing backend. 
Since we had all the equipment that works under dvswitch it was very low 
priority on our list to get working. Right up there with me working out 
how to use my cockatiel Modo as a pirate prop (poor bugger still 
recovering from missing me at Pycon)

Having Evenstreamr working solved an awful lot of problems that any 
solution I know of wouldn't. Like the combining of the rooms. 
Evenstreamr made that happen and prevented bad naming of dvs missing 
videos etc.

That said to quote your reference "DV is on the way out (it's hard to 
even *find* a camera with DV anymore these days)" I fully agree with and 
that is why we do need to work on a solution. Gst-switch is definitely 
something we need to look at as I think it provides that solution. 
However according to Ryan Verner the hardware to replace the dv hardware 
doesn't work. Take hdmi to usb3. The devices stop working randomly. Okay 
if you know what to do and have experience but show stopper in the hands 
of an inexperienced volunteer.

We would have lost videos and the cost of buying the needed hdmi to usb3 
($200-$400/device which would be $400-$1200/room) and the rental of 
computers or the purchase of usb3 cards etc etc would be greater than if 
we had the la equipment shipped multiple times.

He uses something that Mark found which is Blackmagic cards but they 
only work under Linux as pci-express cards which would mean buying 
desktops. Painful to move and expensive.

If gst-switch works as Tim Ansell says it does, I can see no reason why 
it shouldn't, then integrating it with Evenstreamr and the work that 
Joel, Kim, Ryan Stuart (not to be confused with Ryan Verner. I've seen 
them in the same room as each other.) should be one goal that we need to 
set.

Dvswitch maybe dead but right now a better solution is still yet to be 
fully develop. Going with dvswitch for Pycon was the right decision if 
only because we really had no other option.
