Obtaining the AV/C Model from a BeBoB device

You need to compile libffado from source, in order to get the necessary test tools. You also need graphviz.

in the libffado compilation directory run:

tests/test-ffado -v5 Discover 1> stdout.log 2> stderr.log

In the stdout.log you will find a section:

 digraph avcconnections {
   ...
 }

Example

For a QuataFire? 610 it looks like this:

digraph avcconnections {
	"(26) MSU Output 1-8" -> "(0) ASU Audio Input 1394"
	"(0) ASU Audio Input 1394" -> "(16) FB Audio In MixFW"

Copy this section into a separate file and name it my_device.dot.

You can now convert the dot file to a ps file (or svg, ...) by running

dot -Tps my_device.dot -o my_device.ps

Example

dot -Tps quatafire.dot -o quatafire.ps

Results in the attached file: quatafire.ps
