There is a known issue in ActiveX for IceLink 3.0.11 that is causing the user to have to click "Allow" several times in order for local and remote media to be displayed. Once the user has installed the CAB and allowed access three times, it no longer prompts the security warnings on subsequent calls. The work-around is to add the domain that the CAB is hosted from to Trusted Sites. This issue has been resolved so that security prompts are no longer required and sites do not need to be set as Trusted. The fix is being shipped in 3.0.12.
There are also several known issues related to h.264 in iOS and macOS for 3.0.11 that are also being addressed in IceLink 3.0.12. It is recommended to not use h.264 with the 3.0.11 release and wait on 3.0.12 before deploying applications that utilize FMIceLinkVideoToolboxH264Encoder/Decoder to production.
