I have found that Gotomeeting recorded webinars are streamed as MMS streams. It is well known that MMS streams can be downloaded/saved. For instance VLC has a corresponding option in the Open Network Stream dialog.
After a webinar attendees receive a link that after certain manipulations leads to an ASX URL. The ASX (Advanced Stream Redirector) has a simple structure
<ASX VERSION="3.0">
<ENTRY>
<REF HREF="mms://[...].akamaistream.net/[...].wmv" />
</ENTRY>
</ASX>
The stream is packaged in the Windows Media Video format. Video is encoded as G2M4 (a gotomeeting format) and Audio is encoded as DivX v2.
Unfortunately on my machines this G2M4 codec is not available neither in Windows Media Player and Media Player Classic on Windows 7, nor in VLC on my Linux machine.
I am sure mencoder
would have no problem saving this mms
stream and posted my solution that uses it on Gotomeeting community board.
So my question is twofold. How do I get the G2M4 Codec for use with GUI tools such as VLC or Windows Media Player, or are there ways to save a stream into a file that do not involve the use of tools such as mencoder
that are not always available and are considered complicated by many users?
