This topic introduces the transitions between different states of a MediaLive channel and the operations to start and stop a channel in the console.
Channel states
The following state machine diagram illustrates the transitions between channel states:
IDLE: The channel is inactive. This is the initial state after creation.
STARTING: The channel is in the process of being started.
RUNNING: The channel is started and working normally.
STOPPING: The channel is in the process of being stopped.
RECOVERING: The channel is attempting to recover one or more failed tasks until they are successful.
Start and stop a channel
After creating a channel in MediaLive, you must start it manually. The channel will automatically restart only when it has recovered from a failure through retries.
You can stop a running channel at any time.
