Does anyone know if it's possible to configure the stream from the camera to the DS to use MPEG4? Doing so directly on the camera via its web config interface doesn't have any effect on the stream used by the DS - it appears the DS is over-riding the on-camera settings, probably via VAPIX or ONVIF.

No, we can only use MJPEG. The reason for that is that H.264 and the other format are pure video formats, whereas with MJPEG each frame is an individual picture that can be pulled out of the video feed and be processed immediately. H.264 and other formats only encode the changes between frames (which is why they use less bandwidth), meaning that if you wanted to process a frame with those formats you would need to process a dozen other frames to get one frame.
