Get list of video cameras and information about them

GET http://IP Address:port/prefix/camera/list − get all available original sources (cameras) of Axxon-domain.

The returned VIDEOSOURCEID identifiers will have the format as follows "HOSTNAME/ObjectType.Id/Endpoint.Name". Friendly name and other related meta data will also be received.

Parameter	Required	Description
limit	No	Determines the maximum number of returned results, the default value is 1000.
next_page	No	The value of the nextPageToken parameter, which will be in the response if the request returns not all the results. It is used to get the following values.
filter	No	Allows getting a subset of the results in accordance with the filter. Currently it can have the HOSTNAME or VIDEOSOURCEID values. Attention! If Office is specified as the Server name, then the GET http://IP-address:port/prefix/camera/list?filter=Office request will receive all video cameras of Office Server.
group_ids	No	List of the group identifiers to which the cameras should belong (see Get list of groups and their contents). It is possible to specify several identifiers using the separator "\|". For example: http://localhost:80/camera/list?group_ids=6af92229-43ff-0347-9dae-081bf9835733\|b48111eb-64c5-294c-a69c-4adb07c954d1 In this case, the response will contain all the cameras that belong at least to one of the specified groups.

Get camera live stream

On page:

General information
HLS video
RTSP video
HTTP video
Tunneling RTSP over HTTP
H.264 and H.265 video

Important!

You can get audio from x64 Server only.

You can't get audio in MJPEG format.

General information

GET http://IP Address:port/prefix/live/media/{VIDEOSOURCEID}

{VIDEOSOURCEID} – a three-component source endpoint ID (see Get list of video cameras and information about them). For instance, "SERVER1/DeviceIpint.3/SourceEndpoint.video:0:0".

Important!

If no parameters are specified in the request, then the video will be received in the MJPEG format.

Parameter	Required	Description
format	No	Parameter values are "mp4", "hls". Video can be received in the original format (without recompression) via HLS protocols. HLS protocol supports only H.264 format. The "mp4" player allows to receive the original video in H.264 and H.265. In all other cases the server re-compresses it to MJPEG format. Important! If video is requested in the format that differs from the original one, then recompression will be performed, therefore, Server load will increase.
w, h	No	w – frame width, h – frame height. Note If h and w values are more than size of original video, the video will be received with original size. Zooming out of width and height is available only discretely – in 2, 4, 8 times, etc. If specified sizes are not corresponding to 1/2, 1/4 etc. of original video size, the video will be received with size divisible by the original video size close to specified values. Important! The mp4 video is transferred without scaling.
fr	No	fps. Important! This parameter is relevant only for MJPEG video.
enable_token_auth	No	Get signed links to video streams. enable_token_auth – enable authorization by token = 1. valid_token_hours – signature validation time (in hours). The maximum value is a week. The default value is 12 hours.
valid_token_hours	No
key_frames	No	1 – playback only by key frames; 0 – original frame rate (default).

Sample request:

GET http://IP Address:port/prefix/live/media/Server1/DeviceIpint.23/SourceEndpoint.video:0:0?w=640&h=480&enable_token_auth=1&valid_token_hours=1

HLS video

HLS protocol video can be received in the original format only. The following parameters are in use when receiving HLS protocol video:

Parameter	Required	Description
keep_alive	No	Time in seconds in which the stream is to be kept alive.
hls_time	No	The segment length in seconds.
hls_list_size	No	The maximum number of playlist entries. If set to 0 the list file will contain all the segments.
hls_wrap	No	The number after which the segment filename number wraps. If set to 0 the number will be never wrapped.

Sample request:

GET http://127.0.0.1:80/live/media/SERVER1/DeviceIpint.23/SourceEndpoint.video:0:0?format=hls&keep_alive=60

Sample response:

{
    "keep_alive_seconds": 60,
    "keep_alive_url": "/live/media/hls/keep?stream_id=7e9d8c93-80e2-4521-9a54-cb854fe3cd2d",
    "stop_url": "/live/media/hls/stop?stream_id=7e9d8c93-80e2-4521-9a54-cb854fe3cd2d",
    "stream_url": "/hls/7e9d8c93-80e2-4521-9a54-cb854fe3cd2d/playout.m3u8"
}

Parameter	Description
keep_alive_seconds	Time in seconds in which the stream is to be kept alive.
keep_alive_url	The url to keep the stream alive.
stop_url	The url to stop the stream.
stream_url	The url to access the list of segments.

Important!

HLS protocol video becomes available with some delay (about 20 seconds). This is due to a feature of the HLS protocol: after receiving the link, it forms a cache of several video segments, and only after that the video starts playing.

To playback video via HLS protocol use the stream_url parameter from the response as follows:

ffplay "http://root:root@10.0.12.65:80/hls/c83b48d5-2ab7-49eb-91ef-593f808d4e51/playout.m3u8"

RTSP video

RTSP protocol video is sent in the original format only.

Request to get the structure of the RTSP link: http://login:password@IP-address:Port/live/media/Server1/DeviceIpint.23/SourceEndpoint.video:0:0?format=rtsp

Sample response:

{
    "http": {
        "description": "RTP/RTSP/HTTP/TCP",
        "path": "hosts/Server1/DeviceIpint.23/SourceEndpoint.video:0:0",
        "port": "8554"
    },
    "rtsp": {
        "description": "RTP/UDP or RTP/RTSP/TCP",
        "path": "hosts/Server1/DeviceIpint.23/SourceEndpoint.video:0:0",
        "port": "554"
    }
}

Request to get video: GET rtsp://login:password@IP Address:554/hosts/Server1/DeviceIpint.23/SourceEndpoint.video:0:0

Important!

In some cases, the RTSP video can be streamed with artifacts. To fix this, change the TCP/IP settings using this reg file.

RTSP stream information:

GET http://IP Address:port/prefix/rtsp/stat

HTTP video

ffplay.exe -v debug "http://login:password@IP Address:8001/live/media/Server1/DeviceIpint.23/SourceEndpoint.video:0:0?w=1600&h=0"

Important!

HTTP sends video in mjpeg only, w and h parameters are mandatory.

Tunneling RTSP over HTTP

See Configure tunneling RTSP over HTTP in VLC.

Video is sent over the tunnel in the original format.

Sample request:

ffplay -rtsp_transport http "rtsp://login:password@IP Address:80/rtspproxy/hosts/Server1/DeviceIpint.23/SourceEndpoint.video:0:0"

GET for VLC: rtsp://login:password@IP Address:80/rtspproxy/hosts/Server1/DeviceIpint.23/SourceEndpoint.video:0:0

H.264 and H.265 video

To get live video in the original H.264/H.265 format use mp4 format.

Sample request:

ffplay.exe "http://root:root@192.168.25.112:8001/live/media/Server1/DeviceIpint.61/SourceEndpoint.video:0:0?format=mp4"

Get camera snapshot

GET http://IP-Address:port/prefix/live/media/snapshot/{VIDEOSOURCEID}

{VIDEOSOURCEID} – three-component source endpoint ID (see Get list of video cameras and information about them). For instance, "SERVER1/DeviceIpint.3/SourceEndpoint.video:0:0".

Parameter

Required

Description

w

h

No

w – frame width, h – frame height.

Note

If h and w values are more than size of original frame, the frame will be received with original size.

Zooming out of width and height is available only discretely – in 2, 4, 8 times, etc. If specified sizes are not corresponding to 1/2, 1/4 etc. of original frame size, the frame will be received with size divisible by the original frame size close to specified values.
