fluent-ffmpeg throwing SIGSEGV in nodejs
22 mars 2023, par C GI am using fluent-ffmpeg to resize a video, split into frames, etc.
Here's my code :


ffmpeg("./uploads/video.mp4")
 .output("./uploads/small-video.mp4")
 .noAudio()
 .size('320x?')
 .on('end', function() {
 extractVideoFrames("./uploads/small-video.mp4")
 })
 .run()



I am getting a SIGSEGV error, which I suspect might be because of some weird memory issue ?
Here's the error :


Error: ffmpeg was killed with signal SIGSEGV
 at ChildProcess.<anonymous> (/home/admin/superformweb/node_modules/fluent-ffmpeg/lib/processor.js:180:22)

I have installed ffmpeg first :

Then I installed node packages :

npm install ffmpeg

"ERROR : libopencv not found" when compiling ffmpeg
13 avril 2023, par ArnoBenI am trying to install ffmpeg with the libopencv libraries and it fails with the error "ERROR : libopencv not found".


I did install libopencv with
sudo apt install libopencv-dev
which now printslibopencv-dev is already the newest version (3.2.0+dfsg-4ubuntu0.1)
, and I can see the files in/usr/include/opencv2
.

Here is my full script to compile ffmpeg :


cd ~/ffmpeg_sources && \
wget -O ffmpeg-snapshot.tar.bz2 https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 && \
tar xjvf ffmpeg-snapshot.tar.bz2 && \
cd ffmpeg && \
PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
 --prefix="$HOME/ffmpeg_build" \
 --pkg-config-flags="--static" \
 --extra-cflags="-I$HOME/ffmpeg_build/include" \
 --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
 --extra-libs="-lpthread -lm" \
 --ld="g++" \
 --bindir="$HOME/bin" \
 --enable-gpl \
 --enable-gnutls \
 --enable-libopencv \
 --enable-libtensorflow \
 --enable-libx264 \
 --enable-libfdk-aac \
 --enable-nonfree && \
PATH="$HOME/bin:$PATH" make -j4 && \
make -j4 install && \
hash -r



It works fine if I remove the
--enable-libopencv
line.

I'm running Ubuntu 18.04.6.


Any help would be appreciated.
