If i configure ffmpeg this way:
./configure --disable-everything --enable-static --disable-shared \
--enable-gpl --enable-nonfree --enable-encoder=h264_videotoolbox,aac \
--enable-muxer=mp4 --enable-protocol=file --enable-libfdk-aac
--enable-videotoolbox --disable-autodetect
it works for my purposes (allows to encode h264 video with aac audio on Mac's videotoolbox - an Apple QSV toolkit), but if i send it to any other computer except the one it was built on, it fails with something like this:
dyld: Symbol not found: _kCVImageBufferTransferFunction_ITU_R_2100_HLG
Referenced from: /Users/admin/Downloads/./ffmpeg
Expected in: /System/Library/Frameworks/CoreVideo.framework/Versions/A/CoreVideo
in /Users/admin/Downloads/./ffmpeg
Abort trap: 6
if i rebuild it this way:
./configure --disable-everything --enable-static --disable-shared
--enable-gpl --enable-nonfree --enable-encoder=aac
--enable-muxer=mp4 --enable-protocol=file --enable-libfdk-aac
--disable-autodetect
so with everything else but videotoolbox removed, it runs successfully on any other computer, so apparently ffmpeg needs to carry along something it doesn't, for videotoolbox to work...
i am actually building a C++ app with ffmpeg's static libraries, but explaining what i do there will be a very long story and error message produced is exactly the same if i run it on different machines, so i better illustrate it on example of ffmpeg console utility itself.
what are the configure switches i need to do to make the ffmpeg build portable please?
Problem turned out to be my macos version (10.14), the API mentioned is since 10.13, so it didn't work on earlier version i tried. Fixed by rebuilding ffmpeg on 10.10.

I'm trying to get to work hardware acceleration on my Raspberry pi 4-64. I'm using FFmpeg and AFAIK hwaccel can be reached by using OpenMAX or V4L2-M2M.
After '--enable-omx' and 'enable-omx-rpi' for FFmpeg, build fails with error: 'OMX_Core.h not found'. If I will provide manually omx headers, then it will compile but FFmpeg encoding will fail due to missing libraries: bcm_host.so and libopenmaxil.so
I have tried reverting to userland by DISABLE_VC4GRAPHICS = "1", it produced bcm_host.so, but not libopenmaxil.so. I have tried different combinations of virtual providers and graphics settings but without success.
Is it possible to access omx hardware acceleration on RPI4-64?
Steps to reproduce the issue:
1.Download latest Poky distro, meta-openembedded, meta-raspberrypi
2.Enable omx, omx-rpi support for FFmpeg
3.Link headers for FFmpeg
4.Build and try to use h264_omx
How do I get missing library libopenmaxil.so and everything I need for hwaccel?
poky master: commit 5d47cdf448b6cff5bb7cc5b0ba0426b8235ec478
meta-openembedded master: commit daa50331352c1f75da3a8ef6458ae3ddf94ef863
meta-raspberrypi master: commit 8d163dd
BTW, by using V4L2-M2M, I'm getting green shadows on the resulting video. Maybe can someone point me in the right direction?
You have to provide some extra flags to point ffmpeg to the right header and library locations, both at compile time and at run time.
This is what I used to cross-compile ffmpeg for AArxh64:
./configure \
--arch="${HOST_ARCH}" \
--target-os="linux" \
--prefix="/usr/local" \
--sysroot="${RPI_SYSROOT}" \
--enable-cross-compile \
--cross-prefix="${HOST_TRIPLE}-" \
--toolchain=hardened \
--enable-gpl --enable-nonfree \
--enable-avresample \
--enable-libvpx --enable-libx264 --enable-libxvid \
--enable-omx --enable-omx-rpi --enable-mmal --enable-neon \
--enable-shared \
--disable-static \
--disable-doc \
--extra-cflags="$(pkg-config --cflags mmal) \
-I${RPI_SYSROOT}/usr/local/include \
-I${RPI_SYSROOT}/opt/vc/include/IL" \
--extra-ldflags="$(pkg-config --libs-only-L mmal) \
-Wl,-rpath-link,${RPI_SYSROOT}/opt/vc/lib \
-Wl,-rpath,/opt/vc/lib"
Note that pkg-config is configured for cross-compilation as well, it looks in the Raspberry Pi sysroot, not in the build machine root. This is done by setting the right environment variables here.
The -I flags specify the include paths, and the -L flags returned by pkg-config --libs-only-L are the library paths. -Wl passes a list of comma separared arguments to the linker. -rpath-link is used to find shared libraries required by other shared libraries at link time, -rpath is used to find the libraries at run time. This is required because the userland libraries are in a nonstandard location, ld will not search in /opt/vc/lib by default.
You can find the toolchains, Dockerfiles and install scripts I used on my GitHub: https://github.com/tttapa/RPi-Cpp-Toolchain/tree/master/toolchain/docker/rpi3/aarch64/aarch64-cross-build
The userland script is here: https://github.com/tttapa/RPi-Cpp-Toolchain/blob/76ac03741bc7b7da106ae89884c7bada96768a07/toolchain/docker/rpi3/aarch64/aarch64-cross-build/install-scripts/userland.sh
And the ffmpeg script is here: https://github.com/tttapa/RPi-Cpp-Toolchain/blob/76ac03741bc7b7da106ae89884c7bada96768a07/toolchain/docker/rpi3/aarch64/aarch64-cross-build/install-scripts/ffmpeg.sh
There's some more documentation about the compilation process and the files used in the repository here (though not specifically about ffmpeg).
I need to compile a static FFmpeg on macOS and add this build to a Xcode project. If I download a full version from official website that is work. But this version size is huge, and I just need a few format to convert. So I need to compile by myself.
I've tired to compile and it's worked. But I am not sure how to select compile parameter.
For instance, I need to convert: ogg,flac,opus,webm files to mp3 file with the minimum size. And my compile parameter :
./configure --enable-ffmpeg --enable-small --enable-static --enable-protocol=file,http,https --enable-libvorbis \
--enable-libopus --disable-ffplay --disable-ffprobe --enable-demuxer=mp3,mp4,webm_dash_manifest,opus,flac,ogg \
--enable-decoder=mp3*,vp*,mpeg4*,opus,flac --enable-libmp3lame --disable-autodetect --disable-network --enable-pthreads
But it seems not to work, I can't convert files. Error reason is dyld: Library not loaded: /usr/local/opt/lame/lib/libmp3lame.0.dylib.But I used parameter --enable-static.
So what should I do? If I need to support a format to convert, I need to care about which respect? Thanks
--enable-static is applied to ffmpeg libraries but not its dependencies. You need to download and compile lame as static as well.
I need ffmpeg with hardware acceleration.
I am compiling ffmpeg following this guide:
https://gist.github.com/Brainiarc7/eb45d2e22afec7534f4a117d15fe6d89
x264 never works after compile.
I follow the official guide, adding "--enable-shared", compile again, still no luck.
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
Simply installing libx264-dev does not work as well.
$ ldd ~/bin/ffmpeg | grep x264 libx264.so.155 => not found
Does anyone know how to make x264 work?
Thanks.
Is there not any error message when you configure ffmpeg?
Or you can command ffmpeg, and show the configuration like
configuration: --enable-shared --enable-libx264 --enable-libx265 --enable-gpl --enable-nonfree
Maybe you can try install x264 from source.
You can use VCPKG to install ffmpeg with x264 support this project is avaliable on GIT.
Its a straight forward installation using VCPKG.

I'm trying to use my GPU for video encoding/decoding operations on macOS.
OS: MacOS 10.12.5 (Sierra) //hackintosh if it matters
CUDA Toolkit 8.0 installed
NVidia GTX 1080 with latest web driver
Followed this guides:
https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX
https://developer.nvidia.com/ffmpeg
Config:
./configure --enable-cuda --enable-cuvid --enable-nvenc \
--enable-nonfree --enable-libnpp \
--extra-cflags=-I/Developer/NVIDIA/CUDA-8.0/include \
--extra-ldflags=-L/Developer/NVIDIA/CUDA-8.0/lib
Got this error:
ERROR: cuvid requested, but not all dependencies are satisfied: cuda
config.log - full configure log
I did not install Video Codec SDK (not sure how to make it on macOS, just thought that it may come with cuda toolkit) and according to this page I have a lot of limitations on OSX.
Is it possible on macOS? Or this will work only for linux/windows?
I am installing ffmpeg utility, but I am facing libmp3lame >= 3.98.3 not found not found error. I am able to find lame-3.99.5-1.el6.rf.x86_64.rpm and lame-libs-3.98.4-1.el6.nux.x86_64.rpm but installing these are not solving the problem. I am not able to find libmp3lame rpm to install.
Can anyone help me here?
[root#sdp-dev-03:/opt/ffmpeg] # ./configure --prefix="$HOME/ffmpeg_build" --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin" --extra-libs=-ldl --enable-version3 --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvpx --enable-libfaac --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libvo-aacenc --enable-libxvid --disable-ffplay --enable-gpl --enable-postproc --enable-nonfree --enable-avfilter --enable-pthreads

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user#ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.
What worked for me was building lame from source. Download lame from here: https://sourceforge.net/projects/lame/files/lame/3.99/, then extract and install:
tar -zxvf lame-3.99.5.tar.gz
cd lame-3.99.5
./configure
make
sudo make install
Check to see where libmp3lame.a is:
locate libmp3lame.a
Its probably in /usr/local/lib.
Now when you go to configure ffmpeg, try adding that path to the end of your ./configure string. For me it made the difference. e.g.:
--extra-ldflags=-L/usr/local/lib
For configure troubleshooting see the ffbuild/config.log in the ffmpeg source directory.
In my case it had missing references to libmath functions, even if -lm was set in host_extralibs.
For a quick-fix add -lm to the configure script:
enabled libmp3lame && require "libmp3lame >= 3.98.3" lame/lame.h lame_set_VBR_quality -lmp3lame -lm
I just experienced this problem. I had lame v3.99.5 installed, but ffmpeg configure was giving ERROR: libmp3lame >= 3.98.3 not found.
In addition to --extra-ldflags, I had to specify --extra-cflags. So, the configure line was:
./configure [...] --enable-libmp3lame [...] --extra-ldflags=-L/usr/local/lib --extra-cflags=-I/usr/local/include
On Ubuntu 16.04
sudo apt-get install yasm libmp3lame-dev
Then configure ffmpeg to build from source with libmp3lame:
./configure --enable-gpl --enable-libmp3lame --enable-shared
In my case the solution for ffmpeg/3.1.3 (based on https://github.com/Homebrew/legacy-homebrew/issues/44489) was to add:
--host-ldflags=-L/usr/local/lib
to the configure string.
this is my way:
install X11,and goto ffmpeg path,and code this in the Terminal:
pkg-config usr/local/lib
pkg-config usr/lib
pkg-config usr/X11/lib
then code ./configure xxxx.
