I've started poking through the available dmSDK bits, and noticed that very few codec implementations have been provided. (Well, none, to be accurate.) Is this not within the intended scope of the dmSDK? I noticed in particular on the dmSDK OSS web page's News section references to a news item that mentioned DV compression/decompression among other things... Does SGI intend to open source any of these components of dmSDK, or just the core library itself? I understand that there may be licensing difficulties in doing so...

We will probably not be open sourcing the MPEG or DV codecs for this reason. The null codec is provided as a skeleton dmSDK module into which you can plug the appropriate calls to your codec. It's hoped that this module will be useful as an example for those wishing to develop codecs for dmSDK. If an outside party produced an open source MPEG dmSDK transcoder module, we would be very happy, but we probably would not be able to include it in our open source distribution (although we would be happy to advertise it on the dmSDK web site). If an outside party produced an open source Ogg Vorbis dmSDK transcoder module, we would be very happy and would include it in our distribution. We welcome any such contribution.
