Hi, did you also install the vid.stab library itself? It cannot be found at runtime. You can either install it in the system (with sudo make install) or use LD_LIBRARY_PATH to point the linker to the path of the lib file.
Hope it helps.
It looks like I need export LD_LIBRARY_PATH before running ffmpeg every time I start a new shell, I don't know if this is the expected behaviour, but it works this way.
It depends on your intentions. Mine was to create a static build of ffmpeg because there is often a lot of trouble getting RHEL and derivative distros to agree on shared library version requirements... so I just opt to build and statically link the requirement. But to do that you have to decipher the switch to generate static libraries. In this case I was able to use:
cd ~/ffmpeg_sources
git clone https://github.com/georgmartius/vid.stab.git
cd vid.stab
cmake -DCMAKE_INSTALL_PREFIX:PATH=$HOME/ffmpeg_build -DBUILD_SHARED_LIBS:bool=off .
make
make install
So, if you're intending to link static libs, this error happens because vid.stab defaults to shared. If you're intending to use shared libs then that's another whole can of worms.
Also, another word of caution, be careful of the sudo make install
. I don't doubt that sudo
is required to do the install to the system shared library, but not only is it not required for local builds but I had it set root permissions on some of the folder structure and subsequent build steps failed because they lacked root permissions. I would use it only in the correct context.
Dear all,
I followed this guide to compile ffmpeg. Before doing so I got the source code for the vid.stab library from GitHub and did
within the follwoing directory structure:
At last, I compiled ffmpeg and exported
LD_LIBRARY_PATH
. However, when I run ffmpeg, I receive the following error message:./ffmpeg: error while loading shared libraries: libvidstab.so.1.1: cannot open shared object file: No such file or directory
Does anybody have an idea of what could have gone wrong? I can see
libvidstab.so.1.1
in ffmpeg_build/lib.Thanks a bunch.
