Hi, Would like to confirm if we understand the issue. So if _libpostproc-dev_ is in the command, the error is shown. And if there is no _libpostproc-dev_, the ffmpeg package can be installed. Is this understanding correct? ---

I am running into the exact same issue while trying to build torchaudio. Ive been following the steps provided by Pytorch → [Building on Jetson — Torchaudio 2.3.0 documentation](https://pytorch.org/audio/stable/build.jetson.html) After the install fails I am unable to uninstall ffmpeg or repair the install. I have Jetpack 6.0, Linux R36.3, and Ubuntu 22.04. Is there a diffrence in the ffmpeg from the Ubuntu repo vs. NVIDIA repo? ---

Hi @DaneLLL, libpostproc-dev is a base package and is a dependency for most of the libav\*-dev, and maybe a few more. if i only install ffmpeg i believe the installation goes fine, and the opposite is also true. Saying that ffmpeg is blocking a lot of other packages from installing. > **[Debian -- Details of package libpostproc-dev in sid](https://packages.debian.org/sid/libpostproc-dev)** > > FFmpeg library for post processing - development files ---

Did apt remove, update, install ffmpeg. Looks like they linked to a file that is not available to aarch64/arm64 r36.3. (ffmpeg: error while loading shared libraries: libdav1d.so.7: cannot open shared object file: No such file or directory). Did they compile ffmpeg on an x86\_64 machine? because on my hp workstation the file the updated for Jetson ffmpeg wants is: /usr/lib/x86\_64-linux-gnu/ **libdav1d.so.7.0.0** : ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=c1cbf344111237f101e726679363918a0a83fdd3, stripped ---

I got around this for now by directly installing the ffmpeg from another ppa. 1. `vim /etc/apt/sources.list.d/nvidia-l4t-apt-source.list` 2. Comment the line - `deb https://repo.download.nvidia.com/jetson/ffmpeg r36.3 main` 3. `sudo add-apt-repository ppa:savoury1/ffmpeg4` 4. `sudo apt-get update` 5. `sudo apt remove ffmpeg` 6. `sudo apt install ffmpeg.` This is a temp fix and looses all the nvidia optimizations ---

I’m sorry for sounding rude, but is’nt a Raspberry Pi a cheaper version (and well supported) of Jetson Orin Nano without any CUDA optimisation? My frustration is that i’ve now reflashed my board, resetup the whole and still unable to get the ffmpeg working.
