How to broadcast from a custom data source?



I am developing an application to monitor images which have been generated in a custom format from a live data source (in our case EPICS). This is not a DV stream from a Firewire or a video capture card. I have looked at the QuickTime Broadcaster API and it seems that I need to create a custom Sourcer component, but the relevant API is undocumented and I haven't found any examples that would shed light on that particular API. The sample codes seem to assume video is coming in via the sequence grabber which is not relevant to my project.

I know how to capture data from the data source and I can generate an image an convert it to a QuickTime movie if necessary. I just don't know how to get the broadcaster API to broadcast a live stream from the custom data source.

thanks,
