Global configuration(Overall config)

A. Overall config:You can set common protocol switches for all channels in a unified manner, including HTTP(TS), HLS, RTMP (Server/ pull stream), RTSP, multicast (UDP multicast/unicast), and push streams (Client/ RTMP and RTSP).

Multicast Address supports automatic increment of IP or Port:

-Such as setting the “233.233.2.1:3000 +”, then the channels of multicast address in the order: “233.233.2.1:3000”, “233.233.2.1:3001”, “233.233.2.1:3002″…

-Such as setting the 233.233.2.1 + : “3000”, the passage of multicast address in the order: “233.233.2.1:3000”, “233.233.2.2:3000”, “233.233.2.3:3000″…

Note: Multicast requires the permission of the network environment and usually requires a switch with IGMP management capability and is configured correctly.  To configure UDP unicast, you only need to change the multicast address to the IP address of the target device.  

Stream config

Set the output protocol switch or address of each channel. The push stream address supports RTMP, RTSP, SRT and other push stream protocols.

TS config

A.Flow control and bandwidth: The two parameters limit the maximum rate at which UDP packets are sent to prevent packet loss.

B.RTP Head: When this switch is enabled, the UDP TS stream carries an extra RTP header. .

HLS config

Note that HLS fragment data is stored in memory to protect Flash lifetime. If the fragment length or list number is too large, memory will be insufficient.  

SRT config

A.For details about how to set SRT parameters, see SRT descriptions or examples in “Connecting Third-party Software to vMix“.

B.You can also refer to the blog post “Introduction to three modes of encoder SRT protocol (listener, caller and rendezvous)” .

Note: The modification of SRT parameters takes effect after the restart. The password must contain at least 10 characters.  

NDI config

NDI Name: Channel name displayed for automatic NDI discovery

NDI grouping: It is recommended to leave blank

Note: If you buy an encoder without AN NDI license, it can only be used for 30 minutes each time NDI is turned on.

Pull config

A. HEVC ID: The FLV package used by standard RTMP does not support HEVC(H.265), so you need to use a custom extension ID to extend the package. The ID commonly used by international video platforms is 12.

B. Format: Auto is recommended.

C. Push speed(Upload speed): When channel push flow is enabled, the real-time upstream push rate can be displayed here.

As shown in the figure above, all playable protocol addresses will be organized in this interface according to the output protocol you currently enable, which can be easily copied to other playback systems for use.
