DeepStream 7.1 on Jetson Orin Nano — nvvideoconvert (NVMM → system memory) silently fails in headless mode, producing 0-byte encoded files

1. Supported headless NVMM → system-memory conversion

Is there a supported way to make nvvideoconvert produce system-memory output in a fully headless environment on Jetson Orin Nano + DeepStream 7.1?

I have tested this without connecting a monitor, and it works. However, I need to verify one point: after flashing JetPack, have you never connected a monitor to configure the Orin Nano?

2. Recommended headless encode topology

@tech204

Orin Nano does not have NVENC, so I am not sure whether nvv4l2h264enc is actually usable on this platform.

Do not use nvv4l2h264enc on Orin Nano devices; it will not work due to the absence of the necessary hardware module. x264enc is recommended.

Please refer to this FAQ, for this sence, it provided a detailed resolution.
