TCP & UPD Control

Configuration

Go to the Settngs menu and choose the Comm tab.

TCP Listen

This field contains all the ip addresses and ports the TCP command module will be listening to, each line represents an ethernet IP followed by a port, separated by a colon :.

Use an asterisk * as a wildcard to specify all Ips in the host.

Examples:

• Listen to adapter with IP 192.168.1.229 on port 7000: 192.168.1.229:7000
• Listen to all local adapters on port 2500: *:2500

TCP

Once configured, Exaplay can be controlled via TCP, and can send commands via TCP as well.

TCP IN (Receive)

Exaplay will listen for TCP text line messages, ending with a CR. The return messages are sent ending with CRLF.

Each section of the message, as well as the parameters, should be separated by commas ,. The main format structure should be as follows:

Command	,	address	,	Parameters (,,,)

Many commands are adressed to a specific composition (playlist or timeline). In Exaplay, compositions are represented as a tab, and they are adressed by an unique ID:
\

When using TCP-commands, the addressing of compostions follows this keyword scheme

comp[ID] // e,g, comp1 for composition with ID 1

Available commands

Command	Description	Return
hello	Echo test	hallo
get:ver	Returns the current Exaplay version.	e.g. 2.21.0.0
play,comp[ID]	Starts the playback of the addressed composition. Example: play,comp1	OK or ERR
stop,comp[ID]	Stops the playback of the addressed composition. Example: stop,comp1	OK or ERR
pause,comp[ID]	Pauses the playback of the addressed composition. Example: pause,comp1	OK or ERR
set:cuetime,comp[ID],[s.s]	Moves the play cue to a given time for a timeline composition. Parameter: Time in seconds (seconds.fractions) Example: set:cuetime,comp1,2.0	OK or ERR
set:cue,comp[ID],[i]	Moves to a given index, in case of a timeline composition will be a cue, in case of a cuelist composition, it will be a clip index. Parameter: Index, starting from 1 Example: set:cue,cuelist1,2	OK or ERR
set:vol,comp[ID],[i]	Sets the volume of a composition Parameter: Volume value from 0 to 100 Example: set:vol,comp1,60	OK or ERR
get:vol,comp[ID]	Returns the current volume of a composition. Example: get:vol,comp1	e.g. 60
get:status,comp[ID]	Retrieves the current status values for a composition object. Return values: 1. Current playback status. 0=stop, 1=playing, 2=pause 2. Current time in seconds 3. Current frame index 4. Current clip index (valid for cuelist compositions) 5. Total composition duration in seconds Example: get:status,comp1	e.g 1,15.65,939,-1,300

TCP OUT (Send)

It is possible to send arbitrary TCP text line messages at certain events, configured as cue commands in Exaplay.The format structure is as follows:

TCP	>	IP Address : Port	,	Message

Example:

• To send the message ‘hello’ to the address 192.68.50.10 listening at port 5000: TCP>192.168.50.10:5000,hello

UDP

UDP Out

It is possible to send arbitrary UDP text messages at certain events, configured as cue commands in Exaplay. The format structure is as follows:

UDP	>	IP Address : Port	,	Message

Example:

• To send the message ‘hello’ to the address 192.68.50.10 listening at port 5000: UDP>192.168.50.10:5000,hello
