[ZED][Encoding] Critical Error : No Video Enc [enc_0]

I cannot record on GPU. When I use the H.264 or H.265, It shows this

Hi @han12580
What’s your host device or GPU model?

[han12580]

No host. Do you mean this?

[Myzhar]

The Jetson Orin Nano is your host, the ZED is the device.
The Jetson Orin Nano has no hardware encoders, so you cannot use H264/H265 compression when recording SVOs.

[han12580]

OK THANKS.
When recording SVOs, It has many dropped frames. The FPS just is 10. How to up? The Jetson Orin Nano(8G) uses SSD.

[Myzhar]

You need and SSD with a fast write speed and you must be sure that the resolution/framerate settings are correctly handled by the Orin Nano.
You should also set the Orin into 15W power mode (10W if an Orin Nano 4GB) and run the jetson_clocks.sh script to use the maximum available computing power.
