The "Octopus CI" from "Digital Devices" is the only one I know where you can input the TS stream directly to the CAM: http://shop.digital-devices.de/epages/62357162.sf/en_GB/?ViewObjectID=370117 11 > > > -- > To unsubscribe from this list: send the line "unsubscribe linux-media" > in the body of a message to majord...@vger.kernel.org More majordomo > info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
