Push and pull AWS Cloud inputs
When an input is being deployed in the AWS Cloud, it is categorized in terms of how MediaLive and the upstream system negotiate delivery:
-
Push input with handshake.
-

-
Pull input.
There are different limits and charges for push inputs compared to pull inputs.

Note about RTMP push inputs
An RTMP push input works as follows: The source attempts to deliver to an endpoint that is specified in the MediaLive input. There must be a handshake between the source and the MediaLive channel so that the source has information about the status of the input.
When you start the channel that includes this input, MediaLive responds to the handshake message and ingests it. When the channel is not running, MediaLive does not react; the source goes into a paused state.
