3. Types of messages
|
||||||
|
The server and the client send messages over the network to
|
||||||
|
communicate with each other. The messages can be of any type which
|
||||||
|
includes audio messages, video messages, command messages, shared
|
||||||
|
object messages, data messages, and user control messages.
|
||||||
|
3.1. Command message
|
||||||
|
Command messages carry the AMF-encoded commands between the client
|
||||||
|
and the server. These messages have been assigned message type value
|
||||||
|
of 20 for AMF0 encoding and message type value of 17 for AMF3
|
||||||
|
encoding. These messages are sent to perform some operations like
|
||||||
|
connect, createStream, publish, play, pause on the peer. Command
|
||||||
|
messages like onstatus, result etc. are used to inform the sender
|
||||||
|
about the status of the requested commands. A command message
|
||||||
|
consists of command name, transaction ID, and command object that
|
||||||
|
contains related parameters. A client or a server can request Remote
|
||||||
|
Procedure Calls (RPC) over streams that are communicated using the
|
||||||
|
command messages to the peer.

The client or the server sends this message to send Metadata or any
|
||||||
|
user data to the peer. Metadata includes details about the
|
||||||
|
data(audio, video etc.) like creation time, duration, theme and so

3. Types of messages

The server and the client send messages over the network to

communicate with each other. The messages can be of any type which
|
|
||||||
includes audio messages, video messages, command messages, shared
|

||||||
object messages, data messages, and user control messages.
|
|
||||||
3.1. Command message
|
|
||||||
Command messages carry the AMF-encoded commands between the client
|
|
||||||
and the server. These messages have been assigned message type value
|
|
||||||
of 20 for AMF0 encoding and message type value of 17 for AMF3
|
|
||||||
encoding. These messages are sent to perform some operations like
|
|
||||||
connect, createStream, publish, play, pause on the peer. Command
|
|
||||||
messages like onstatus, result etc. are used to inform the sender
|
|
||||||
about the status of the requested commands. A command message
|
|
||||||
consists of command name, transaction ID, and command object that
|
|
||||||
contains related parameters. A client or a server can request Remote
|
|
||||||
Procedure Calls (RPC) over streams that are communicated using the
|
|
||||||
command messages to the peer.
