According to latest requirement, when the level reported by RtpSender.getCapabilities() for H.265 is different from that was negotiated, we should not throw when setParameters() is called with level-id set to that reported by RtpSender.getCapabilities(). Underlingly negotiated codec level should remain unchanged.
