No, the UDP protocol is currently not supported. This means that the Mine Media M4 can no longer transmit SRT. (The Mine Media Q8 and Q9, on the other hand, can already transmit via SRT.)
The Mine Media M4 currently only supports the TCP protocol, as the Mine Media M4 uses MPTCP for bonding. The menu item “UDP” for bonding is not yet active. (As of October 2021)
UDP is used, for example, for VMix Call, SRT or certain functions in Zoom or Teams. However, there are often fallback functions, so that Zoom also works to a limited extent via TCP.
