error: failed to run custom build command for `ffmpeg-sys-next v6.0.1`

[OktoberfestTheEnthusiast]

I'm trying to build a cargo with RUST but I always seem to get this error upon installing these ffmpeg crates

**error: failed to run custom build command for ffmpeg-sys-next v6.0.1

Can anybody help me with this issue? Thank you!

I had the same with libavfilter and libavdevice, turns out ffmpeg-sys-next 6.0.1 needs both of them, so the necessary packages to install are (excerpt from my devcontainer's Dockerfile):

RUN apt-get update && export DEBIAN_FRONTEND=noninteractive \
    && apt-get -y install --no-install-recommends \
    clang \
    libavcodec-dev \
    libavdevice-dev \
    libavfilter-dev \
    libavformat-dev \
    libavutil-dev \
    pkg-config

Hi, how to fix it in Windows?

[openersoft]

try this: vcpkg install ffmpeg:x64-windows

I managed to fix it after 7 hours of work. What I did was using the GNU build guide found in the build wiki of this repo. Afterwards I: installed vcpkg ran vcpkg integrate install ran: vcpkg install ffmpeg[core,avcodec,avformat,swscale,avdevice,avfilter] --triplet x64-windows --recurse The avdevice component includes libavdevice, and the avfilter component includes libavfilter.

You should than get this error: usr/include/libswresample/swresample.h is missing error (or something along these lines, it will appear at the bottom of the screen) the file is located in this path (if you used the default download location for vcpkg) : C:\Users\USERNAME\vcpkg\buildtrees\ffmpeg\src\n5.1.2-f31542651f.clean (libswresample will be one of the folders in here) move it over to: C:\Users\USERNAME\vcpkg\installed\x64-windows\include

run cargo build again and it should work just fine.

#160 is a duplicate. I tried to answer there
