Yes, you can do that, but only if the hardware supports it. Most cards with CAM/CI are hardwired in such a way that the transport stream comes from the demodulator, goes through the CAM/CI and then into the PCIe/PCI bridge. There are only a few cards where you can send a TS from memory to the CAM/CI and back. -Ralph -- 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
