AVB isn't dead no, but it certainly isn't close to dominant at this point, at
least on my side of the pond. It may be a different situation on the other
side,
no idea. That being said, it has a very uphill battle to displace Dante at this
point on my side of the pond and get decent usage professionally.
You are exactly right. However, for most of us, it is a matter of what can
work with Linux and has open drivers. Right now nothing. The chances of
some Dante box having a linux OS in it is probably quite high, but I can't
even buy a closed version at this point (though I hear there are some
around). And the HW to go with such a driver is not cheap (at least not
cheap enough for me to buy when it may never work).
Then again if AES67 interoperability comes into play, then is may be a moot
point
as ideally you would be able to communicate between the two protocols.
AES67 right now is the same. There are no Linux drivers and none in the
works so far as I know. There are some audio cards that are basically
AES67 ends, but again they are not cheap.
AVB is far from dominant for sure, but there is an open driver (well sort
of... a group of bits that can be put together to make things work is more
like it) in the works. It does require some special HW, but the gist of
the thread is that the cost of that HW has come within reach. In other
words, the average experimenter with no backing can start to tinker.
There is an option to still make use of AVB equipment if one can't make
this work, not cheap ($600) but similar to a USB AI with the same feature
set that will act as either a USB (USB2.0 compliant it says) AI with AVB
bridging or as an AVB AI. SO not a loss if things don't go well or not
unusable while working on things. The internals can be controled via a web
browser on the avb port even with no AVB stuff attached.
Along with this, parts of the linux AVB driver and HW needed (the NIC for
example) will be usable for AES67 development if someone chooses to do
that.
So AVB development may not seem like the best way to go, but right now it
is the only way that at least seems open and in the end seems to also have
the edge quality wise (perhaps that is debatable... I won't bother arguing
either way).
So for me, it is about accessability. I am a hobbiest (at this point
anyway) and Dante/AES67/Ravenna are out of my reach. AVB seems to have
entered into that accessable place.
One thing I will say is that Dante and AVB can coexist on the same
network, it should not be very hard to make a box with only one NIC that
can bridge the two... and make whatever in on one protocol look like it is
on the other.
