Install Multimedia API Alone

Autonomous Machines Jetson & Embedded Systems Jetson Nano
1

Hi,

I tried to install the multimedia API of JetPack 4.3 by itself on Nano. I cannot find the compressed file from Jetson Download Center | NVIDIA Developer any more. There is only a document about the API (L4T Multimedia API Reference: Data Structures). If using SDK Manager, all other SDKs will be installed to Nano, which takes a long time. I also checked the download folder of all SDKs on the host PC and only found a DEB package that does not install on Nano.
So is there still a way to install the API alone for JetPack 4.3?
Thank you very much!

Adrian

They’re now in the Nvidia online repos. You should be able to “sudo apt install nvidia-l4t-jetson-multimedia-api” (but at least on my Xavier these were already installed)

The samples are in /usr/src/jetson_multimedia_api

Hi,

Thank you for the reply!
I did sudo apt install nvidia-l4t-jetson-multimedia-api and it was already installed. But I cannot find “jetson_multimedia_api” folder under /usr/src.

Huh. Can you do a “dpkg-query -L nvidia-l4t-jetson-multimedia-api” and paste what pops out? It is for sure there for me on my Xavier.

Hi,

Here is the terminal output.

~$ dpkg-query -L nvidia-l4t-multimedia

That’s a different package (i know, it’s confusing, there are like 3 similarly named packages), can you try “dpkg-query -L nvidia-l4t-jetson-multimedia-api”

Result from my Xavier:

$ dpkg-query -L nvidia-l4t-jetson-multimedia-api

OK, I realized that there are 2 very similarly named packages nvidia-l4t-multimedia and nvidia-l4t-jetson-multimedia-api. I installed the previous one by mistake. Now it works. Thank you!

No worries. Like I said, it’s confusing. I think the -jetson- package is basically a *-dev package with headers, documentation, samples and so on, while the others are the libraries proper.

Where can I find the .deb for this package?

I don’t see it alongside the other .deb files…

$ tar jtvf jetson-210_linux_r32.6.1_aarch64.tbz2  | grep multimedia

You just sudo apt-get install nvidia-l4t-jetson-multimedia-api. The debian package (and any it might depend on) should be downloadable directly via it’s link here:

https://repo.download.nvidia.com/jetson/

Same result in the end.
