INGEST API - Socket Commands
Using third party applications, users can easily connect to Ingest. In this section, we will use Telnet application to connect to Ingest. As shown on the figure below, the computer running Ingest has been connected to Telnet. In order to access to Ingest, the user should enter the command;
o <hostname> <portnumber>
o : open
host name: the name or IP of the computer running Ingest
port number: the port to which third party applications connect to Ingest (please see Remote Control settings. )
Where Ingest is computer name, example Metus1.
Ingest has two responses to TCP commands;
FAILED: shows that the command couldn’t be executed successfully. The user has not defined any profile for ‘Encoder 1’ as shown on the first command below, so that this encoder can’t be started without any profile.
OK: shows that the command is executed without any problem. The user has defined a profile to start successfully.
1.EncStatus [encoder name] : Displays status of an encoder.
Example: (The commands user entered has been shown in bold text)
EncStatus TestEncoder1
OK: TestEncoder1:Prepared
The possible results of EncStatus [encoder name] command;
No encoder exists : no encoder has been defined yet.
None: indicates that the encoder has been disposed.
Running: shows that recording has just been started.
Runned: shows that Ingest has been capturing the media source.
Stopping: indicates that recording has just been stopped.
Stopped: indicates that the current encoder stopped capturing.
Pausing: shows that recording has just been paused.
Paused: shows that the encoder paused capturing.
Preparing: indicates that the user has just defined either encoder or encoder and its profile.
Prepared: indicates that the user has defined either encoder or encoder and its profile
Splitting: indicates that the user has clicked <split> button.
Splitted: shows that recording has been splitted.
Error: shows that error has just been found.
