| Enum | Description |
|---|---|
| AV_SCREEN_CAPTURE_ERR_BASE = 0 | Basic value of an error code. The number of other error codes increases based on this value and is used to identify different error types. |
| AV_SCREEN_CAPTURE_ERR_OK = AV_SCREEN_CAPTURE_ERR_BASE | Operation successful. |
| AV_SCREEN_CAPTURE_ERR_NO_MEMORY = AV_SCREEN_CAPTURE_ERR_BASE + 1 | Insufficient memory. Possible causes: The system memory is insufficient. Solution: Check the recording parameters or system memory status. |
| AV_SCREEN_CAPTURE_ERR_OPERATE_NOT_PERMIT = AV_SCREEN_CAPTURE_ERR_BASE + 2 | Operation not allowed. Possible causes: The required permission has not been obtained for the current operation or the operation is invalid. Solution: Check the operation permission and current status, and try again. |
| AV_SCREEN_CAPTURE_ERR_INVALID_VAL = AV_SCREEN_CAPTURE_ERR_BASE + 3 | Invalid parameter. Possible causes: The input parameters do not meet the API requirements or the parameter values are out of the allowed range. Solution: Check the parameter type and value range, and try again. |
| AV_SCREEN_CAPTURE_ERR_IO = AV_SCREEN_CAPTURE_ERR_BASE + 4 | Abnormal input and output streams. Possible causes: The file fails to be read or written, or a data transmission error occurs. Solution: Check the file path, permissions, and storage space, and try again. |
| AV_SCREEN_CAPTURE_ERR_TIMEOUT = AV_SCREEN_CAPTURE_ERR_BASE + 5 | Network timeout. Possible causes: The Internet connection is unstable, or the server response times out. Solution: Check the Internet connection status and try again. |
| AV_SCREEN_CAPTURE_ERR_UNKNOWN = AV_SCREEN_CAPTURE_ERR_BASE + 6 | Unknown error. Possible causes: An unexpected exception occurs. Solution: Check the log information. |
| AV_SCREEN_CAPTURE_ERR_SERVICE_DIED = AV_SCREEN_CAPTURE_ERR_BASE + 7 | Media service terminated. Possible causes: The media service process crashes or is terminated by the system. Solution: Check the system resources or restart the service. |
| AV_SCREEN_CAPTURE_ERR_INVALID_STATE = AV_SCREEN_CAPTURE_ERR_BASE + 8 | Unsupported operation in this state. Possible causes: The instance is in an error state when the interface is called. Solution: Check the current state and call the interface according to the correct process. |
| AV_SCREEN_CAPTURE_ERR_UNSUPPORT = AV_SCREEN_CAPTURE_ERR_BASE + 9 | Unsupported interface. Possible causes: The current version does not support this interface or function. Solution: Check the API version or device compatibility. |
| AV_SCREEN_CAPTURE_ERR_EXTEND_START = AV_SCREEN_CAPTURE_ERR_BASE + 100 | Unexpected error. Possible causes: An unexpected exception occurs. Solution: Check the detailed error information. |
