AWS medialive documentation change
Summary
Expanded pipeline locking documentation to include single-pipeline channels using linked channels, added CMAF Ingest as supported output type, introduced pipeline locking methods (source timecode and video alignment), and updated section titles.
Security assessment
Changes describe functional enhancements to pipeline locking without addressing vulnerabilities or security features. No evidence of security fixes or weaknesses addressed.
