[Jack-Devel] AES67 / SMPTE ST 2110-30

[Philippe BEKAERT]

Hi Christophe and others,


There has been little progress here on AES67 support in jack. We had to give priority to other issues in response to clients requests at azilpix. However, its still on the list. In fact, I'd need only a couple of work days to finish a first sharable version of a AES67 jack client.

I am also interested in evaluating your students work, whenever ready.

Best,

Philippe.

Initially windows reported an error and it did not work. Went back to Ubuntu 17.10 on the same machine and it worked fine. (Same result as another person before me). Disabled the internal NIC and started Windows again. Voila, it worked ! Re-enabled the on-board NIC and it kept Working in windows. Just for reference.  Don't have a AVB audio device so cannot really test them. Looking if there is any AVB test software out there to use these two cards to transmit AVB based audio from one to the other.
>> From talking to Focusrite regarding AES67 and the Rednet series and firmware support, got the following:  "With regards to AES67 compatibility, this is possible for devices using the 'Brooklyn 2' Dante chipset. RedNet 3s ship with a 'Brooklyn 1' chipset, though it's possible to upgrade to a Brooklyn 2 (this would be chargeable). All of our devices using Brooklyn 2 modules have AES67 compliance following the latest firmware update available from RedNet Control"  (Focusrite Rednets use the Bonjour/mDNS protocol for discovery)

Hopefully suppliers will support some kind of new standard in the future for that as well ( HTML XML, JSON  or other open messaging over IP to configure the unit). The Rednet3 will keep the routing/configuration after power cycling thus until then that should be done under Windows.
