• FFmpeg build error pkg-config can't find x265 /usr/bin/ld : cannot find -lnuma : No such file or directory

  1er janvier 2023, par slyfox1186

  I am trying to build ffmpeg with custom libraries from source code.

  


  Every package in my script builds as it should but when it gets time to run the ffmpeg build using all of the packages it fails with a weird error code shown at the bottom of the ffmpeg build log.

  


  BEGIN /home/jman/tmp/ffconf.JouXp6kg/test.c
    1   #include 
    2   #include 
    3   long check_x265_api_get(void) { return (long) x265_api_get; }
    4   int main(void) { int ret = 0;
    5    ret |= ((intptr_t)check_x265_api_get) & 0xFFFF;
    6   return ret; }

  Does anyone know what this -lnuma is referring to ?

  


  I had no issues just a few days ago when I last ran my build script and then all of a sudden this issue appeared.

  


  This is my build script in its entirety : FFmpeg-build.sh

  


  Update : Per Allan Winds' instructions here is the output of :

  


  find /usr/lib -name libnuma\* -ls

• brodcast png & video ffmpeg with raspberry

  6 mars 2021, par FoxFr

  Someone can help me to add a image during 10s beetwen the videos ?
or explain me how do that

  


  ffmpeg \
-i /dev/video0 \
-i /dev/video2 \
-i /home/pi/videopi/map.png \
-stream_loop -1 -re -i "/home/pi/videopi/bed.mp3" \
-filter_complex "[0][1]overlay=enable='lt(mod(t,60),30)'[v];[v]drawtext=textfile=/home/pi/videopi/gps.txt:reload=1:x=30:y=100:fontfile=OpenSans.ttf:font$
-map "[v]" \
-map 2:a \
-c:v libx264 -b:v 4000k -maxrate 4000k -bufsize 8000k -g 50 -c:a aac \
-f flv rtmp://a.rtmp.youtube.com/live2/XXXXXXXXXX


  


  Below the sequence wished

  


  |-> video0 - duration 30" --> map.png - duration 10" --> video2 - duration 30" --|
|                                                                                | 
|--------------------------------------- loop -----------------------------------|


  


  I'd try to put

  


  -f image2 -loop 1 -i "/home/pi/videopi/acmo/map.png" \


  


  instead of

  


  -i /dev/video0 \


  


  without success

  


• "ERROR : libopencv not found" when compiling ffmpeg

  13 avril 2023, par ArnoBen

  I 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 prints libopencv-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.
