Flash Player Freezing Over Multicast

Large scale testing (60+ IT admins) has been done with Firefox, Chrome and IE 11 on Win7x64, Win8.1 & Win10.

Basically, in cases where either IE or chrome freezes up we are able to actually see that the stream is still being received by the browser consistently. So even when the screen and audio is frozen the process is still receiving the multicast data.

So at least in the case of freezing issues it looks as if we are dealing with something above the network configuration and in the browser/flash issue. We are using IE11 with the embedded flash player, and chrome with the embedded flash player and seeing hard freezes in both.

Observations today are that Firefox (using machine based Flash) may freeze but it is more of a 20 sec or so pause.

We are aware that multicast issues do exist in the wild but would like to be able to pinpoint what exactly is causing this.

We are partnered with INXPO for our Multicasting needs. We utilize an Adobe Media Server that just today was identified as having out of date Flash clients(18). Endusers in the field are currently on 21.0.0.242.

Any suggestions for further troubleshooting? We have run multiple test calls with inconsistent results. All video issues seem to point to Flash.
