Note: Due to the browser compatibility issues, it may cause the web page display abnormal, it is

recommended to use Chrome or Firefox browser.

MG300· User Manual

After login, you can set decoding and other parameters on the Web page. The left window is for preview,

the right is Output 1 and 2. You can close the preview window, Webpage as blow:

5.2 Network configurations

The decoder has two Ethernet ports. Generally, it only needs to configure the address 1 of network 1.

This IP is used for network streaming and device management. The two ports are used as service

separation between LAN and Internet or data flow separation between service and management.

Click "Network" to enter the configuration page. The network interface icon is shown as green to indicate

the normal working state of network, and the network interface icon is shown as orange to indicate the

disconnected state of network.

MG300· User Manual

Each network port can be configured with 2 IP addresses: "Address 1" is configured to be the working IP

of the device; "Address 2" is used as the default management address and device management as well.

Click the "Set" of “Network 1- Address 1” to configure the IP address. You can get your IP address by

"DHCP Dynamic" and "Manual Set". The IP address obtained by DHCP may change, while the IP

address specified manually is fixed for the convenience of device management. IP address configuration

is according to the actual situation of your local network configuration.

To choose manual configuration, you need to set the IP, Gateway, Mask, DNS parameters in turn. If the

local network is in 192.168.4. */24 subnet, you can configure Address 1 to 192.168.4.15, 255.255.255.0,

192.168.4.1, and 8.8.8.8.

After the IP address is configured, you can test whether the IP address can ping through other computers

in the local network, or access the web page of the device through http://192.168.4.15. Only when the IP

address configuration is correct can the device work properly.

The configuration of network port 2 can be set as instructed for network port 1.

NOTE

：

Because the device saves the configuration file to the system regularly, the device cannot

power off immediately after the IP address is manually configured or modified, otherwise the IP

address may be lost. If you want to save the configuration immediately, you can restart the device once

on the web page.

6 Function Configuration

6.1 Media (Video decoding)

Click the "Media" to configure the decoding parameters. There are three main functions: one is to add

video sources and source list; the second is to preview, the third is to display output information such as

streaming, split-screen, layout and etc.

6.1.1 Video source

6.1.1.1 Add RTSP source

Click "Add", then configure the parameters in the pop-up dialog, and click "OK" to add a video source.

Two URL addresses can be added under the same “Name”, one main stream and one sub-stream. The

main stream is for decoding output. The sub stream is for preview. If only filled main stream address,

both preview and output will adopt main stream.

NOTE

：

Please make sure to get the correct URL address of the video source from live platforms.

The abnormal working source address will cause the device not to work properly. (Video source can be

testified by VLC player.)

MG300· User Manual

The above image shows how to add video source through RTSP stream, for other streams, please

check below tables for reference.

The parameters of the video source are defined as follows:

6.1.1.2 Add SRT source

1) Add an SRT source on WEB page by "Media"–"Add Source"–"SRT".

SRT source parameters description as below:

Name: You can name it freely, letters and numbers combination;

Connection Mode: Caller, Listener, Rendezvous;

URL address: When using the CALLER mode, the URL address is: srt:// the peer public IP address: port;

Name Video source name

URL Address

Support RTSP, RTMP, RTMPS, UDP, HTTP and other protocols, decoder can

automatically identify the URL address. After entering the URL address, if some

advanced parameters are configured, the dialog box will auto pop up for your

configuration. You can also click on the protocol options on the page to set the

parameters directly.

Transmission Mode Choose TCP or UDP. TCP is reliable transmission and UDP is unreliable transmission

User/Password Normally, no configuration is required. It depends whether or not the video source is

authenticated by the user.

Decoding buffer and

latency

Various buffer strategies for choice, including zero buffer, 50ms, 120ms, 200ms,

500ms, 1s. It counts on your actual network conditions, good network set with lower

latency, and bad network with higher latency.

Video Receiving Port Network receiving port 1-65535

Audio Receiving Port Network receiving port 1-65535

Binding Network Auto by default

Video Coder Format is [PT,]CODER[/Timestamp-unit],i.e.96,H264/90000

Audio Coder Format is [PT,] CODER

[/Timestamp-unit/channels],i.e.96,MPEG4-GENERIC/48000/2

MG300· User Manual

when using the LISTENER mode, the URL address is: srt://:port

Address: Set IP address of the receiving port;

Port: Configure a listening port which should be consistent with the sending port;

Latency: It depends on the performance of your current network. The Latency can be set at both ends of

the SRT source and the SRT target device, and the larger of the two values will be selected as the SRT

transmission delay;,

Encryption Mode: AES-128, AES-192 and AES-256;

Key: encryption key, fill in 10-32 letters or numbers according to the encryption method;

Bandwidth Overhead: Percentage value that configured according to your network conditions. Multiply

this percentage value by the total video and audio bitrate encoded by the encoder to get the maximum

bandwidth occupied by the overhead allowed by Bandwidth Overhead. The sum of this value and the

video and audio bitrate is the current SRT transmission bandwidth threshold, which is also the maximum

bandwidth available for SRT streams. From the perspective of "overhead", it is the extra "invalid"

bandwidth to be used in addition to the media content required for transmission (it can be understood as a

payload), but it is different from those common protocol overlay, TCP header overhead or UDP header

overhead. The bandwidth overhead here is not a fixed 20~60 bytes TCP header overhead or 8 bytes UDP

header overhead, but changes in real time according to the network conditions. The worse the network

link conditions, the more the required transmission. The setting range is 5%~100%, and the default size is

25%;

Payload size: The sending data packet size. The receiver should match the same size of the data packet

sent. The default size is 1316, which is the optimal packet size for encoding and decoding.

2) Please drag the added SRT source to the output window, and the decoder starts to listen for SRT

requests, it will establish the SRT connection while receiving the right SRT "Call". After connected, the

status will show “Pull”.
