In the GTC catalog, I am trying to find an image that has nvidia-l4t-jetson-multimedia-api already installed, but im not able to find one.

Currently, im trying to use nvcr.io/nvidia/l4t-cuda:11.4.19-devel and install nvidia-l4t-jetson-multimedia-api manually, but I get the following:

root@EAC-5000:/opt/ros/noetic# sudo apt-get install nvidia-l4t-jetson-multimedia-api

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:

                                    PreDepends: nvidia-l4t-core (< 35.4-0) but it is not installable

E: Unable to correct problems, you have held broken packages.

Any suggestions to move forward here? Due to other stack dependencies, I can not go past ubuntu 20.04.

The motivation for needing nvidia-l4t-jetson-multimedia-api is to enable the compiling and running of the tegra-multimedia-api code examples and modify them for camera applications.

Update 00: for some reason, the /etc/apt/sources.list.d/nvidia-l4t-apt-source.list did not exist in the container. I copied that from the host jetson, then attempted to run an install however it fails now with:

my issue looks very similar to this issue, however, when trying the fix of:

mkdir -p /opt/nvidia/l4t-packages
touch /opt/nvidia/l4t-packages/.nv-l4t-disable-boot-fw-update-in-preinstall
echo "deb https://repo.download.nvidia.com/jetson/t194 r35.1 main" >> /etc/apt/sources.list
apt update
apt install libdrm-dev nvidia-l4t-multimedia nvidia-l4t-camera

I get the following error:

In fact, even when running the jetpack image (not sure how i missed this in the first place) with

docker run -it --rm --net=host --runtime nvidia -e DISPLAY=$DISPLAY --gpus all --name container-toolkit-2 nvcr.io/nvidia/l4t-jetpack:r35.4.1 bash

and trying to compile the baked in sample 01_video_encode I get the following:

root@ai-army-1:/usr/src/jetson_multimedia_api/samples/01_video_encode# make
Compiling: video_encode_csvparser.cpp

And when trying to apply this issues solution I am again left with a similar error:

...

Hi,
Please run $ cat /etc/nv_tegra_release to get your release version, and replace it to the commands. In the sample commands, r35.1 is Jetpack 5.0.2.

6

It looks like in the nvcr.io/nvidia/l4t-jetpack:r35.4.1 image, there is no /etc/nv_tegra_release file:

root@ai-army-1:/# cat  /etc/nv_tegra_release
/usr/bin/cat: /etc/nv_tegra_release: No such file or directory

However, using the tag of the docker image r35.4.1 works!
So the fix to get past

NvDrmRenderer.cpp:18:10: fatal error: xf86drm.h: No such file or directory
   18 | #include <xf86drm.h>

here for me is:

mkdir -p /opt/nvidia/l4t-packages
touch /opt/nvidia/l4t-packages/.nv-l4t-disable-boot-fw-update-in-preinstall
echo "deb https://repo.download.nvidia.com/jetson/t194 r35.4 main" >> /etc/apt/sources.list
apt update
apt install libdrm-dev nvidia-l4t-multimedia nvidia-l4t-camera

1 Questions on this:
Is there a way to pass in an arg to the following prompt so that i can add this step to a docker file?

Configuration file '/etc/ld.so.conf.d/nvidia-tegra.conf'
 ==> File on system created by you or by a script.
 ==> File also in package provided by package maintainer.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
*** nvidia-tegra.conf (Y/I/N/O/D/Z) [default=N] ? Y

While the previous steps get me past the #include<xf86drm.h> error, hen trying to make the /usr/src/jetson_multimedia_api/samples/01_video_encode sample, i get

/usr/src/jetson_multimedia_api/include/NvVulkanRenderer.h:43:10: fatal error: vulkan/vulkan.h: No such file or directory
   43 | #include <vulkan/vulkan.h>

I tried to install vulkan with

 apt install libvulkan1 mesa-vulkan-drivers vulkan-utils

but im left with the same error.

Im somewhat surprised that I am not able to make any of the samples out of the box, and that I have to do these install steps manually. Is this what you would expect @DaneLLL ?

for installing volkan, i was installing the wrong apt package - I should have been installing:libvulkan-dev. This gets me to the point where i can compile samples within nvcr.io/nvidia/l4t-jetpack:r35.4.1! Woo!

One final thing to track down here is that all of this was being done on my host machine, x86/64 with a QEMU emulator. When trying this on an orin I get the following error:

Any idea why this action would have different behaviors on my host vs the orin? Its the same exact docker image, with the same commands.

Update: If I don’t use --runtime=nvidia --gpus=all then i can run the install no problem

The host version of jetpack is Jetpack 5.1.1 [L4T 35.3.1] , so i attempted to use the respective jetpack image: nvcr.io/nvidia/l4t-jetpack:r35.3.1, but I get a pretty much the same error (subbing 35.4.1 with 35.3.11)

Again, with the fact that this only occurs with --runtime=nvidia. Maybe something with the host nvidia keys are wrong?

Sorry for thrashing, I do appreciate any help :)

Hi,
The package cannot be installed in docker. Please install it in local and and include the path to docker:

Jetson Xavier + docker + ffmpeg - #3 by DaneLLL

Please use the docker version which matches with the local release version.

Hi,

We test l4t-jetpack:r35.4.1 container and the sample can be built with:

$ sudo docker run -it --rm --net=host --runtime nvidia -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix nvcr.io/nvidia/l4t-jetpack:r35.4.1
