50 * Create a device object.
52 * Typically a device object will be created for each tuner.
53 * It is valid to have multiple device objects communicating with a single HDHomeRun.
55 * For example, a threaded application that streams video from 4 tuners (2 HDHomeRun devices) and has
56 * GUI feedback to the user of the selected tuner might use 5 device objects: 4 for streaming video
57 * (one per thread) and one for the GUI display that can just between tuners.
59 * This function will not attempt to connect to the device.
60 * The connection will be established when first used.
62 * uint32_t device_id = 32-bit device id of device. Set to HDHOMERUN_DEVICE_ID_WILDCARD to match any device ID.
63 * uint32_t device_ip = IP address of device. Set to 0 to auto-detect.
64 * unsigned int tuner = tuner index (0 or 1). Can be changed later by calling hdhomerun_device_set_tuner.
65 * struct hdhomerun_debug_t *dbg: Pointer to debug logging object. May be NULL.
67 * Returns a pointer to the newly created device object.
69 * When no longer needed, the socket should be destroyed by calling hdhomerun_device_destroy.
71 * The hdhomerun_device_create_from_str function creates a device object from the given device_str.
72 * The device_str parameter can be any of the following forms:
74 * <device id>-<tuner index>
76 * If the tuner index is not included in the device_str then it is set to zero.
77 * Use hdhomerun_device_set_tuner or hdhomerun_device_set_tuner_from_str to set the tuner.
79 * The hdhomerun_device_set_tuner_from_str function sets the tuner from the given tuner_str.
80 * The tuner_str parameter can be any of the following forms:
