This makes it possible to dynamically add / remove receivers, which is
necesary for sending to multiple receivers. Mixed multi- and unicast
receivers are possible. Example pw-cli calls (56 is the ID of the RTP
sink node):
pw-cli c 56 User '{ extra="{ \"command.id\" : \"add-receiver\" , \"destination.ip\" : \"10.42.0.1\", \"destination.port\" : 55001 }" }'
pw-cli c 56 User '{ extra="{ \"command.id\" : \"remove-receiver\", \"destination.ip\" : \"10.42.0.1\" }" }'
pw-cli c 56 User '{ extra="{ \"command.id\" : \"clear-receivers\" }" }'
Commands and their arguments:
* "add-receiver" : Adds a receiver to the sink's list. If the given
IP address <-> port combination was already added, the command is
logged, but otherwise ignored. Arguments:
- "destination.ip" : IP address to send data to. Can be a uni- or
multicast address, but must be a valid address.
- "destination.port" : Port to send data to. Must be valid.
- "local.ifname", "source.ip", "net.ttl", "net.dscp", "net.loop" :
These are all optional, and work just like in the RTP sink
module's properties.
* "remove-receiver" : Removes a receiver from the sink's list. The
receiver is identified by the given IP address. A port can optionally
be specified as well. If it isn't, then the first receiver with that IP
address is removed. If no matching receiver is in the sink's list,
this command does nothing. Arguments:
- "destination.ip" : IP address to send data to. Can be a uni- or
multicast address, but must be a valid address.
- "destination.port" : Port to send data to. This is optional. But, if
it is set, it must be a valid port number.
* "clear-receivers" : Removes all receivers from the sink's list. If the
list is empty, this does nothing. This command has no arguments.
If the RTP sink module is created with the "destination.ip" and
"destination.port" properties set, it behaves as if "add-receiver" were
called right after the module was initialized. This means that if none
of these commands are used, the module behaves just as it did prior to
this patch. Note that the "remove-receivers" command can remove this
initial receiver as well.
If no receivers are added, the module continues to work normally.
Adding and removing receivers mid-operation is supported.
NOTE: "destination.ip") handling in stream_props_changed() is removed,
since it never really did anything other than change the param value.
