Deb, just re-writing the post where I had written whole method to convert GoToMeeting files into MP4 (https://moodle.org/mod/forum/discuss.php?d=307282#p1242045)
Unfortunately this is the ONLY way you can convert the GoToMeeting files into MP4 format, there is absolutely no other method, either you can follow the steps or else you can keep looking, halting your site with 2 things in the tunnel.
- Conversion of GoToMeeting files into MP4.
- Live Streaming, without the need of Streaming server (essentially free) - However there is a method, but it will have nothing to do with your Moodle / Joomdle site, but viewers can only be able to watch it on VLC players outside the site, so you will actually be broadcasting the stream for ANYONE to get URL and watch for free taking your bandwidth to an essential halt.
If your TEAM can come up with some other idea with their research to live stream without the need of a streaming server, I'll be damned, as after scratching my head in Uni of Manchester's server racks studying streaming media over the internet I couldn't find any alternative to that without the need of a streaming server, once your team come up with a solution, do let me know, I'll update my thesis report with your credentials for sure.
