Remarks
Open a new session at a requested security level. The security level represents the robustness of the device's DRM implementation. By default, sessions are opened at the native security level of the device. Overriding the security level is necessary when the decrypted frames need to be manipulated, such as for image compositing. The security level parameter must be lower than the native level. Reducing the security level will typically limit the content to lower resolutions, as determined by the license policy. If the requested level is not supported, the next lower supported security level will be set. The level can be queried using #getSecurityLevel. A session ID is returned.
