Converting G2M3 and G2M2 encoded Videos (GoToMeeting Videos) to a video type that FFMPEG supports

Question

I'm developing a PHP application that uses FFMPEG-PHP to split videos and convert them to FLV. And I ran into this problem :
FFMPEG does not support G2M3 or G2M2 encoded videos, and I have to make the process of splitting and converting videos effortless for the client, I don't want him to convert the video locally before uploading to the server.
All I want to do is to find a way to convert the G2M3 encoded videos online to FLV or to any other video type that FFMPEG supports.

So, is there any way I can do that?
Can MEncoder handle this type of videos?

Answer 1

I tried doing something similar and could not find a solution. The only workaround I could get together was to use an older version of Windows Media Encoder (think it was version 9), which would let you convert to a different format.

The big hassle was that the GotoMeeting codec was only available on Windows (and maybe Mac). A possible workaround could be to setup GotoMeeting to record using standard WMV, which is not the default setting.

G2M3 is a proprietary codec, see this link on vlc-forum. As the thread says, you will not find a open-src implementation of it.

Google gives me this link for a conversion howto
