The guide now includes information about the new thumbnails feature that lets you view a preview of the current input for the channel. | July 7, 2023 | |
The CloudWatch metrics for AWS Elemental MediaLive channels and multiplex now support a period as low as 1 second. This enhancement gives you the ability to monitor activity in your channels in real time. | June 26, 2023 | |
The information in this section has been revised. Specifically, we now require TLS 1.2 and we recommend TLS 1.3. | June 24, 2023 | |
The guide has been updated to describe a constraint with setting up a channel with epoch locking when an HLS or MediaPackage output group includes SCTE 35 messages. This constraint applies only to epoch locking. It doesn't apply to regular pipeline locking. | June 24, 2023 | |
The information in this section has been revised. Specifically, we now require TLS 1.2 and we recommend TLS 1.3. | June 24, 2023 | |
The information for using HLS output groups to deliver to MediaPackage using the standard MediaPackage API and using the MediaPackage v2 API have both been revised to correct errors, particularly in the examples for the MediaPackage channel URLs. | May 31, 2023 | |
The information about AWS Elemental MediaLive has been reorganized into three main sections, one in Features, one in the setup topics in the navigation bar, and one in the operations topics in the navigation bar. | May 31, 2023 | |
The section about timecode has been renamed to timecodes and timestamps. The section has also been revised to clarify how timecode works in MediaLive. | May 22, 2023 | |
This section has been revised to clarify some points. Pipeline locking now works with a channel that has multiple inputs (a channel that implements input switching). Inputs must have an embedded timecode. The timecode configuration field in General Configuration for the channel has no effect on pipeline locking. | May 22, 2023 | |
This section has been revised to remove incorrect information. Pipeline locking requires an embedded timecode in the input. But you don't need to set the timecode configuration source to embedded. MediaLive always looks for the embedded timecode. | May 22, 2023 | |
