Hi,
Please try this and see if it works:

Nothing changed after running:

sudo apt clean && sudo apt install ffmpeg -y

What nv_tegra_release are you?

When I upgraded to 36.4 it added this line:
“deb https://repo.download.nvidia.com/jetson/ffmpeg r36.4 main” to this file:
/etc/apt/sources.list.d/nvidia-l4t-apt-source.list

and I believe that provides the functional ffmpeg:
ffmpeg 7:4.4.2-nvidia
libpostproc-dev 7:4.4.2-0ubuntu0.22.04.1

Your log above you shows ealier versions.

Hi,
Please try

$ sudo dpkg -i --force-overwrite /var/cache/apt/archives/libpostproc-dev_7%3a4.2.7-0ubuntu0.1_arm64.deb
$ sudo apt --fix-broken install

Not work
The /var/cache/apt/archives/libpostproc-dev_7%3a4.2.7-0ubuntu0.1_arm64.deb doesn’t exist.
So I tried the following:

sudo apt download libpostproc-dev
sudo dpkg -i --force-overwrite ./libpostproc-dev_7%3a4.2.7-0ubuntu0.1_arm64.deb
sudo apt install -f
# As the last command has no effect:
sudo apt install ffmpeg -y

Same error output…

I’m using Xavier, which has an elder Ubuntu and of course elder packages than Orin.
Perhaps the bug is now only fixed on Orin.

Hi,
We can run the commands successfully on Jetpack 5.1.4/Xavier:

$ sudo apt update
$ sudo apt install ffmpeg libpostproc-dev
$ sudo dpkg -i --force-overwrite /var/cache/apt/archives/libpostproc-dev_7%3a4.2.7-0ubuntu0.1_arm64.deb
$ sudo apt --fix-broken install

Great!
But as I’ve already installed libpostproc-dev, so I run the following command first before yours:

$ sudo dpkg --ignore-depends libpostproc-dev -r libpostproc-dev
