Do you have a monitor connected? If you choose sink type =2 (EGL) you will need connect a monitor on the Nano to get EGL initialized. ---

**There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks** 1.Your env have some problems cause `no such element factory "nvstreammux"!`. 2.If you don’t have display env, you can set the sink type to fakesink. We suggest you refer to the link below to install component step by step.
