From 00df62c3054d966e2aa8a9b08ce2b1c381f9c3e3 Mon Sep 17 00:00:00 2001 From: yair Date: Sun, 16 Nov 2025 03:25:33 +0200 Subject: [PATCH] Improve IDS uEye error handling with comprehensive error code mapping - Replaced garbled is_GetError() output with human-readable error messages - Added error code mapping for 25+ common IDS errors from uEye.h - Enhanced camera initialization with detailed logging and context - Error messages now include error code, name, description, and troubleshooting hints - Added information about device/camera ID attempted and available camera count - Example: Error 3 now shows 'IS_CANT_OPEN_DEVICE (3): Cannot open device - check if camera is connected and not in use. Camera/Device ID used: 99, Available cameras: 2' Fixes issue where camera initialization failures showed cryptic characters instead of useful error information. --- sys/idsueye/gstidsueyesrc.c | 188 ++++++++++++++++++++++++++++++++++-- 1 file changed, 181 insertions(+), 7 deletions(-) diff --git a/sys/idsueye/gstidsueyesrc.c b/sys/idsueye/gstidsueyesrc.c index ee9894f..44158bd 100644 --- a/sys/idsueye/gstidsueyesrc.c +++ b/sys/idsueye/gstidsueyesrc.c @@ -498,16 +498,60 @@ gst_idsueyesrc_start (GstBaseSrc * bsrc) /* Use device-id if set (non-zero), otherwise use camera-id */ if (src->device_id != 0) { src->hCam = (src->device_id) | IS_USE_DEVICE_ID; + GST_INFO_OBJECT (src, "Attempting to open camera with device-id=%d (handle=0x%x)", + src->device_id, src->hCam); } else { src->hCam = src->camera_id; + GST_INFO_OBJECT (src, "Attempting to open camera with camera-id=%d (handle=0x%x)", + src->camera_id, src->hCam); } + ret = is_InitCamera (&src->hCam, NULL); if (ret != IS_SUCCESS) { - GST_ELEMENT_ERROR (src, RESOURCE, FAILED, - ("Failed to initialize camera: %s", - gst_idsueyesrc_get_error_string (src, ret)), (NULL)); + /* Build comprehensive error message */ + gchar error_msg[1024]; + const gchar *error_str = NULL; + + /* Get descriptive error from our mapping */ + switch (ret) { + case IS_CANT_OPEN_DEVICE: + error_str = "Cannot open device - check if camera is connected and not in use"; + break; + case IS_INVALID_DEVICE_ID: + error_str = "Invalid device ID - check device-id parameter"; + break; + case IS_INVALID_CAMERA_HANDLE: + error_str = "Invalid camera handle"; + break; + case IS_CAMERA_NOT_CONNECTED: + error_str = "Camera not connected"; + break; + case IS_ALL_DEVICES_BUSY: + error_str = "All devices are busy - close other applications using the camera"; + break; + case IS_NO_HARDWARE_INSTALLED: + error_str = "No hardware installed"; + break; + case IS_SENSOR_INITIALIZATION_FAILED: + error_str = "Sensor initialization failed - check power and connections"; + break; + default: + error_str = gst_idsueyesrc_get_error_string (src, ret); + break; + } + + g_snprintf (error_msg, sizeof(error_msg), + "Failed to initialize camera (error code %d): %s.
