audio and subtitle switching tests should be added to LIVE tab (single period tests)
Does Livesim2 support ac4? Should we have an example?
@bobcampbell-resillion Livesim2 does not support Dolby AC4
audio track at the moment. I asked about this in Slack channel and they lack a public free-to-use test material.
Dolby has few AC4 test files and dash manifests, I do not know the licensing rights.
Dolby AC4 mp4 (or AC4-IMS for mobile devices). https://ott.dolby.com/OnDelKits/AC-4/Dolby_AC-4_Online_Delivery_Kit_1.5/help_files/topics/kit_wrapper_MP4_multiplexed_streams.html
