Hi, I’ve got tx2 with JetPack 4.2. Now, I want to use hardware decode for video.

I find that there is a module called nvdecode, which seems to complete such jobs.

Is there any material to get started ? Many thanks !

Hi,
Please check gstreamer and tegra_multimedia_api documents:

Thanks for your quick reply. I’ve got another question. Can tegra_multimedia_api capture RTSP video streaming ? If can, what should I do?

Thanks in advance.

Hi,
tegra_multimedia_api is low level APIs and you have to integrate into your usecase. For rtsp, you may check live555 http://www.live555.com/

For a quick solution, you may use gstreamer:
