In my case the pipeline is potentially complex, given that it's implemented in an FPGA. The bridge driver just parses the DT pipeline representation and binds subdevs together. It has no concept of simple or complex pipelines. I've thus decided to go for an MC model, even for simple pipelines. > Secondly, I'd love to add MC support to qv4l2.

I assume that's a hint :-) I've just posted a series of patches for libmediactl. Let's take it from there. -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
