mpeg4 part 10 is h.264. So, are you sure the camera does not already have native h.264 support? If it does you can use this guide to re-restream directly from the camera:

Otherwise, the VLC guide is here:

You can adapt one of the VLC examples, and/or there are others you can find by searching this forum that would be better suited to your case.
