It's not entirely clear what you want to do. Bus messages are inappropriate for communication between elements. It might be possible to force them into doing that, but it wouldn't be a good idea. > For video data fusion, I need to communicate forensic data acquired from one > plug-in and pass it on to another. > I was hoping to accomplish this through the GstBus. > If this is not possible & I need to use a GstEvent, is there any > functionality lost in using an event handler for this purpose? > If you want to communicate data between elements, then that's what gstreamer's core dataflow is all about - why not just send GstBuffers containing the data? Events and messages are different, but without any details at all about what sort of data you're sending, and what exactly you're sending them between, I couldn't say whether the differences matter for your purposes. It does sound like you need a better understanding of the core gstreamer concepts though - once you understand how gstreamer is intended to work, it's likely that the right solution to your problem will be pretty obvious.
