Error opencv #1

Closed soheer closed 2 years ago

soheer commented 2 years ago

Hello,

we've downloaded opencv4 (version 4.5.5) from source and we want to build ffmpeg package with opencv using this configuration (+ transform 360 package to transform 360 videos [https://github.com/facebook/transform360]):

./configure --prefix=/usr/local/transform/ffmpeg --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvo-amrwbenc --enable-version3 --enable-bzlib --disable-crystalhd --enable-fontconfig --enable-frei0r --enable-gcrypt --enable-gnutls --enable-ladspa --enable-libaom --enable-libdav1d --enable-libass --enable-libbluray --enable-libdrm --enable-libjack --enable-libfreetype --enable-libfribidi --enable-libgsm --enable-libmp3lame --enable-nvenc --enable-openal --enable-opencl --enable-opengl --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-librsvg --enable-libsrt --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libvorbis --enable-libv4l2 --enable-libvidstab --enable-version3 --enable-libvpx --enable-libx264 --enable-libx265 --enable-libxvid --enable-libzvbi --enable-avfilter --enable-libmodplug --enable-postproc --enable-pthreads --enable-gpl --disable-debug --disable-stripping --enable-nonfree --enable-libfdk-aac --enable-libopencv --extra-libs='-lTransform360 -lstdc++' --extra-ldflags=-L/usr/local/lib

but we have error : ERROR: opencv not found using pkg-config even though when running pkg-config --modversion opencv4 we got the opencv version

what should we do to solve this problem?

Thanks.

opencv install issue not the best place to find help. Why do you install opencv includes just like they suggest ? sudo apt-get install libopencv-dev

You can also try some of the advice from this issue https://github.com/facebook/transform360/issues/56 especially this : https://github.com/facebook/transform360/issues/56#issuecomment-412466165

Maybe this version (v5) of ffmpeg isn't the appropriated one of this filter (transform360), the last commit are older than 9 months ago. You can test but I won't be surprise if you'll encounter errors after solve this lib dependency error... Go to the v4 ffmpeg version of this work is the best option to start with.
