The users list is a better place to discuss this, but thats an old version, try using the latest release and if you still have issues, try the users list.

In particular, we are seeing an issue where sometimes the video element in HTML will start streaming videos just fine, but most of the time, one side of the video call, or both, will have a screen being pitch black. The audio is totally fine though.

I looked into the source code, which corresponds to the switch_rtp.c file, it seems like the "srtp_protect()" function, which transforms/encrypts an RTP packet into SRTP packet, returns an error code. I tried by patching it with the changes here: https://freeswitch.org/jira/browse/FS-10667 <https://freeswitch.org/jira/browse/FS-10667>, since it seemed like a similar issue, but it didn't work either. I understand there are several ways to go about this: 1) stick a debugger or 2) try out the latest version.
