Yes it can, but only one of them can use the CCDC, preview engine and resizer. The other will be captured directly to memory as raw data. You could capture both raw streams to memory, and then feed them alternatively through the rest of the pipeline. Whether this can work will depend on the image size and frame rate. > - is it possible to simulate a kind of video stream that is externally > triggered (I would use a gpio line that simply triggers 10 times a > sec) or would there arise problems with the csi2 protocoll (timeouts > or similar)? I don't think there will be CSI2 issues (although I'm not an expert there) if you trigger the sensors externally. -- 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
