Hi there, I’m having issues with NVIDIA ffmpeg package as it is having a conflict with libpostproc-dev and subsequently all of libpostproc-dev’s dependencies such as libav*. below is the error message After this operation, 56.2 MB of additional disk space will be used. debconf: delaying package configuration, since apt-utils is not installed (Reading database … 206247 files and directories currently installed.)

Hi, The package is refreshed. Please re-install it and try again.

Hi, If you don’t re-flash the whole system, please remove the installed ffmpeg deb first: $ sudo apt remove ffmpeg $ sudo apt update $ sudo apt-get -y install ffmpeg libavutil-dev libavcodec-dev libavformat-dev libavdevice-dev libavfilter-dev libswscale-dev libswresample-dev libswresample-dev libpostproc-dev libjpeg-dev libpng-dev libopenblas-base libopenmpi-dev

[image] DaneLLL: sudo apt-get -y install ffmpeg libavutil-dev libavcodec-dev libavformat-dev libavdevice-dev libavfilter-dev libswscale-dev libswresample-dev libswresample-dev libpostproc-dev libjpeg-dev libpng-dev libopenblas-base libopenmpi-dev Same error, i’ll re-flash and try again

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

Hi, The ffmpeg deb is for Jetson platforms. It does not work on x86 machines.

I get the same error when i try to run ffmpeg on Orin NX 16Gb ffmpeg -version ffmpeg: error while loading shared libraries: libdav1d.so.7: cannot open shared object file: No such file or director I checked for the available version, it is libdav1d.so.5 , how to install libdav1d.so.7?

I’m having the same issue. Straight after a Jetpack 6.0 install on Orin AGX, I installed ffmpeg and it cannot find libdav1d.so.7: ffmpeg -i ffmpeg: error while loading shared libraries: libdav1d.so.7: cannot open shared object file: No such file or directory

I have the same problem. It looks like the repository for l4t r36.3 does not provide libdav1d library with version 7 but only 5 (libdav1d5).

This is also impacting gstreamer, which is what I really need. We cannot downgrade to JP 5.1.3 because we need the TRT version in JP 6.0.

I got around this for now by directly installing the ffmpeg from another ppa. vim /etc/apt/sources.list.d/nvidia-l4t-apt-source.list Comment the line - deb https://repo.download.nvidia.com/jetson/ffmpeg r36.3 main sudo add-apt-repository ppa:savoury1/ffmpeg4 sudo apt-get update sudo apt remove ffmpeg 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.

Hi,
We are checking why it links to libdav1d.so.7.0.0. Will update.

Ad a quick solution please build it from source:
