AVB Switches
- LabX Titanium 411:
Discontinued. Working nicely with some bugs, that wont be fixed. The SFP is working with a Fanisar Multimode LC fiber port (GBit). - DSP4U AVB Switch:
Quite powerful, if accessed via RS232. It can also act as AVB endpoint with an I2S interface. I have to figure out on how to use it. You need a Marvell SDK for development. As usual Marvell is not willing to cooperate. No NDA, and thus no access to the SDK and documentation. - Extreme Networks x440-24t:
24 Port AVB switch with small data center capabilities. Everything you can wish to have for development. The shared SFP is working with a Fanisar Multimode LC fiber port (GBit). But takes extra AVB license.
XMOS AVB
Atterotech XR-AVB-LC-BRD Board: Development board with analog I/O
DSP4U AVB-DG Board: Small OEM board with simultaneous I2S I/O. These would rather make my Behringer ADA8k (which is quite an undertaking) and Yamaha 01v (w. ADAT) AVB ready.
Now my Sound Reinforcement System Breakout AVB Devices for the B1800-d Pro and EAW KF300 are ready and working flawlessly!
Now they have a nice home!
Open AVB
Intel AVB Linux driver for I210 NIC.
At the moment I have three Linux machines running with OpenAVB. Now I am waiting to either find the time to implement the GStreamer AVB Plugins or to wait for someone else to do it. :-)
AVB and AMD APU
I found an industrial mainboard with an AMD APU. Goal was to achieve low latency HD streaming.
The first approach was a Blackmagic Design Deckling 4k HDMI capture card. After two months the BMD support was not able to get it working. Second time I made this experience. BMD Linux support is NOT TRUE!!!
The Second approach was with a Mobius Actioncam. Until now it seems the Video4Linux2 or UVC drivers buffer to much data. Nothing I did decreased the video latency below ~100ms and I was just watching "/dev/video0" and not streaming.
PyQtAVDECC
Qt/Python based AVDECC Controller Software. It is still in an early phase. The next step ahead is to write Cython bindings to interface with the audioscience avdecc-lib.
After that, there shall be a jack-like connection visualisation, with Bézier curves showing established connections.
