I was helping a friend and he seemed to think this might be of interest to the Apple Community.


Here are a couple of options:


1. MPlayer for OSX Version 1.0 rc2 will play the MSS2 Windows Media Video 9 Screen codec. There is no plug-in for watching the video in Safari, however you can use RCDefaultApp to change the Safari mime-type for video/x-ms-wmv so that it uses MPlayer for OSX. This will pop open a new mplayer window and play the video.


2. The Windows Media Video 9 Screen codec has a corresponding codec in Apple Quicktime called the Animation codec.  A Third Party Windows tool like Movavi Video Converter can read the Video 9 Screen codec file and save it to the Quicktime Animation codec format which will play on the Mac.  




Why this works.


#1 works because that project uses dmo to load the windows codecs written to read the format, the newer binaries for MPlayer for OSX Extended didn't really work, only the older version was reliable. This has only been tested on OSX 10.6.8 on a 32 bit Intel machine, so there maybe a different behavior on a 64 bit machine


#2 works because if you start from a Windows machine the native codec is available, and both 9 Screen and Animation are optimized for screen casting, that is they are similar in purpose so there is little if any loss of quality. Conversion is uncommonly fast it zips right along. The Fonts are very legible. After converting to Animation, Quicktime Pro can convert it to H.264 and the view still looks very good. You might want to use QTP because it can also 'hint' the file properly and can save it to device specific formats like AppleTV for presentation. Do not forget to change the Movavi/QPT settings when converting to animation codec to 'Best' quality otherwise it will degrade the video.


I've tried to be as complete as possible in this description, but I do stuff like this all day long. If I left any details out just ask.


I'll watch the thread a few days.


I aplogize if this information is too trivial or obvious, it was posted as a favor to friend.

    MPLAYERX  can play it. Download from here:

    The one from the Appstore is not supported anymore. You can also dual boot  windows and convert with this tool
