avbutil — manage
AVB features and settings.
The avbutil executable is used for the
managment AVB features and settings.
The following options are available:
- --virtual-audio enable if-name [--stream-count stream-count]
[--input-stream-count input-stream-count] [--output-stream-count
output-stream-count] [--channel-count channel-count] [--no-44.1k] [--no-48k]
[--no-88.2k] [--no-96k] [--no-176.4k] [--no-192k] [--no-am824]
[--no-aaf-int] [--no-aaf-float] [--config-per-count]
- Enable the builtin virtual audio entity on the specified interface. With
no additional arguments this enabled the builtin model, with additional
arguments this dynamically creates an entity model with the specified
parameters. --stream-count defines how many audio streams to create,
--channel-count is how many audio channels in each stream. --no-44.1k,
--no-48k, --no-88.2k, --no-96k, --no-176.4k and --no-192k disable each
sample rate. --no-am824 disables IEC-61883-6 AM824 stream format,
--no-aaf-int disables the AAF 24 bits in a 32 bit integer PCM stream
format and --no-aaf-float disables the AAF floating point PCM stream
format. --config-per-count creates multiple configurations with each count
of streams, e.g. if --stream-count is 4 then it creates 4 configurations
the first with 1 audio stream, the second with 2, the third with 3 and the
fourth with 4. The default is 1 stream with 8 channels per stream and all
sample rates enabled. Note IEC-61883-6 AM824 streaming only supports 48k,
96k and 192k sample rates and no stream formats will be created for those
at 44.1k, 88.2k or 176.4k. --stream-count specifies both the input and
output to have the same number of streams, --input-stream-count and
--output-stream-count can be used to specify a different number of streams
for input and output (including 0) but there must be at least 1 input or
output stream.
- --virtual-audio disable if-name
- Disable the builtin virtual audio entity on the specified interface.
- --virtual-audio list
- List the set of interfaces with a builtin virtual audio entity enabled. An
interface must be present and enabled for AVB use to enable the virtual
audio entity on that interface. A virtual audio entity can always be
removed from an interface regardless of if the interface is present or
not.
- --custom-audio add unique-id if-name path-to-entity-model
- Add the custom audio device with the given AEMXML or AEMPLIST entity model
on the specified interface.
- --custom-audio remove unique-id if-name
- Disable the virtual audio device on the specified interface and remove
it.
- --custom-audio list
- List the enabled custom virtual audio devices
- --controller [launch | enable | disable]
- Launch, enable or disable the general AVDECC Controller. Passing no
arguments is the equivalent of passing enable and then passing launch.
Note that enable and disable has no affect and is kept for legacy support.
The general AVDECC Controller is part of the AVB Audio Configuration
utility that lives in the system CoreServices directory. The launch
command is provided as a convenience for not having to find the
application.
- --acquire-mode enable | disable | status
- Enable, disable or check the current status of the acquire mode AVB audio
controller, that is the controller that provides the functionality of the
acquire checkboxes in the Network Device Browser window of the Audio MIDI
Setup application.
- --acquire-mtt-tune enable | disable | status
- Enable, disable or check the current status of the acquire mode Max
Transit Time automatic latency tunning.
- --convert-aem xml-to-plist xml-path plist-path
- Convert AEM xml file to AEM plist file.
- --convert-aem plist-to-xml plist-path xml-path
- Convery AEM plist file to AEM xml file.
- --convert-aem xml-to-c xml-path output-path
- Convert AEM xml file to a series of C data arrays in a C file.
- --convert-aem plist-to-c plist-path output-path
- Convert AEM plist file to a series of C data arrays in a C file.
- --mvrp add bsd_name VLAN-ID
- Add the VLAN ID to the attributes being registered. This will only persist
while avbutil is running
- --mvrp remove bsd_name VLAN-ID
- Remove the VLAN ID from the attributes being registered by avbutil. Note
this will not remove a registration from another application.
- --msrp list bsd_name
- List the all of the MVRP attributes being registered.
