RTSP configuration

dsn rtsp.listenREQUIRED = "*:554:/"

Network settings for incoming RTSP client connections in the <hostname>:<port>:<base-url> format, where:

hostname – refers to a local network name, at the IP address of which connections will be listened to. If * is specified, connections at all network addresses will be listened to, and the current hostname from hostname will be used.
port – refers to a port number that will be open for listening of connections. In specific operational systems, you should allow for not root users to use a port lower than 1024.
base-url – a base path address.

number rtsp.ip = 4

An IP protocol type for incoming connections:

4 – for IP4
6 – for IP6

An array of event identifiers that can be sent. If not specified or empty, all events are sent.The following are the event types:

Event types

service:up – indicates that the service configuration has been successfully accepted and that all services are functioning correctly.
service:down – signifies that the service has received a shutdown signal and is in the process of attempting to cease operations properly, although this event may not always be issued.
service:pulse – the service is currently operational. The event is sent every 60 seconds.
service:emergency – a critical event related to the failure of one of the services or the runtime environment occurred.
stream:create – Mediaserver created a stream. The event takes place when a stream is added.
stream:pulse – a stream is successfully captured. The event is sent with the frequency of sending the PINGcommand to the camera.
stream:reconnect – Mediaserver is attempting to reconnect to a stream.
stream:state – an event occurs when a stream status is updated.
stream:delete – an event occurs when a stream is deleted.
stream:dvr – an event with regard to ranges of a DVR stream. An event occurs when a new range appears.
stream:dvr:delete – an event on deleted DVR ranges of the stream. An event occurs when an old range is deleted.
server:capture – an event of captured server streams.
server:release – an event that signals about the end of the secondary streams capturing.
camera:create – an event on a new camera instance creation.
camera:delete – an event that occurs when a camera instance is deleted.
camera:event – an event that is generated by a camera. Foe example, an event was received via ONVIF or it was placed via Server.PostEvent.
onvif:create – an event that occurs when the ONVIF instance is created on the camera.
onvif:delete – an event that occurs when the ONVIF instance is deleted from the camera.

For details on the Weebhook mechanism, refer to the Configuration of Webhook and notification events documentation page.

    "cluster": {
        "webhook": "http://localhost:8080/event/",
        "events": [
            "service:up",
            "service:down"
        ]
    }
}

SSL configuration

string ssl.key = "string"– a path to the SSL key file.

string ssl.cert = "string" – a path to the SSL certificate file.

JSON

{
    "ssl": {
        "key": "string",
        "cert": "string"
    }
}

Additional parameters for configuration

url streams = "./cameras.json" – the path to the file location that contains the configurations of the captured streams. This parameter overrides the -s parameter of the service startup command line. The source can be designated as either a local file path or a URL, which is expected to return the list of streams along with their respective configurations.

number log.verbose = 4 – the level of the server state logging. The levels of logging are from 0 to 7. Where 7 provides detailed information. This may increase space during logging and reduce efficiency.

url licenseREQUIRED = "url" – specifies the location of the license file: URL or a local file.

string secretREQUIRED = "string" – a secret value that is used to generate authorization tokens to view and access API. Tokens generated with the same secret will be accepted on all servers.

JSON

{
    "streams": "./cameras.json",
    "log": {
        "verbose": 4,
        "out": "stdout|syslog.user"
    },
    "license": "url",
    "secret": "string"
}

Configuration of a virtual storage device

Mediaserver supports virtual storage devices for DVR. To configure a virtual device, define a storage section in your Mediaserver configuration file. Once defined, you can specify this section in the recording and storage path for your DVR. If no storage section is specified, the path defined in the stream configuration will be used as the recording directory. If no storage section is defined, a default virtual storage device with the local driver type will be created.

enum storage.driverREQUIRED = "local"

The driver for the virtual storage device:

dvrfs – a type of the storage device.
local – use directories for storing and recording the archive.

object storage.volume = {}

Is used when driver dvrfs is specified

object storage.volume

string storage.volume.name = "string" –a virtual mount point for the file system (neither devices nor a directory are created). The name can be arbitrary (no spaces, special characters (a-z, A-Z, 0-9,-_.). The name must be specified as a parameter in dvr.location. For details, refer to the Add a stream documentation section.

string storage.volume.option = "string"–additional option dvrfs.

disable-root-write – this option indicates that the root file system cannot be used for DVR recording. If the physical device is unmounted, this option will prevent the root file system from running out of space.

object storage.volume.bucket = {} – an object that contains a mount point of a physical device as a key and the mount point parameters as a value.

mixedstorage.volume.bucket.mountpoint – specifies the mount point.

bytesstorage.volume.bucket.mountpoint.capacity = "bytes" – defines the maximum storage space used. It is used in a special edition, with role determining the purpose of this disk.

enumstorage.volume.bucket.mountpoint.role = "data" – a type that defines the purpose of the disk usage. By default, set as data and will be used for DVR storage. recovery – for storing archive recovery information in case of physical media failure.

JSON

{
    "storage": {
        "driver": "local",
        "volume": {
            "name": "string",
            "option": "string",
            "bucket": {
                "mountpoint": {
                    "capacity": "bytes",
                    "role": "data"
                }
            }
        }
    }
}

Each mount point is checked for existence. If the mount point (directory) doesn’t exist, it won't be created – this prevents accidental writing to the root file system.

For each mount point, the writing capability is determined (filesystem status: rw, ro), as well as the sufficiency of permissions for writing and reading. If writing is not possible, the mount point is marked as "read-only" but is not excluded from the bucket.

After configuration, the storage device for the DVR of each stream can be specified using a device like /bucket0.
