Hi,
I've noticed the release 5.0.0 is now out. I've been trying to use it with jetpack 4.6 and 4.6.1, It seems to not like the jmm build step. Having a look at the d3-build-tegra-media-api I can see that the

declare -A JMM_API_VERSION_ARRAY=( \
    ["32.3.1"]="32.3.1-20191209225816"  # JP 4.3
    ["32.4.2"]="32.4.2-20200408182620"  # JP 4.4 EA
    ["32.4.3"]="32.4.3-20200625213407"  # JP 4.4
    ["32.4.4"]="32.4.4-20201016123640"  # JP 4.4.1
)

string is not yet updated for 4.6(.1) The patch is for 4.4 as well. Does this mean installing the jetpack supported mm api is sufficient without having to run the d3-build-tegra-media-api script or is there a trick that is not in the readme?

Cheers

Hi @ganindu7,

Thanks for bringing this up. You will still need to run the d3-build-tegra-media-api script to use argus_camera. If you don't intend to use any parts of the Jetson Multimedia API, then you could skip this step altogether.

We've been dealing with this annoyance for too long, and clearly it fell through the cracks for this release. Try adding the correct version string to the script: ["32.7.1"]="32.7.1-20220219090344" # JP 4.6.1. That should allow you to continue without hitting the scary error message.

Let me know how it goes!
