  • FFMPEG "Invalid data found when processing input" MP4 to MP3 PHP

    10 février 2014, par CubeBoy69

    I have a question. I'm converting videos from youtube to mp3. From 1000 files around 150 files this message is in the log.

    /home/desktop/www/tmp/314629.mp4 : Invalid data found when processing input

    The thing is it's only about 10% of the conversions. How can i solve this issue ?

    I'm converting like this

    ffmpeg -y -i /home/desktop/www/tmp/'.$random_flv_name.'.'.$download_format.' -vn -map_metadata -1 -ab 192k /home/desktop/www/audio/'.$yt_video_id.'/songtitle.mp3

  • Linking to ffmpeg libraries fails while installing OpenCV

    12 août 2015, par Serhan

    FFMpeg 2.7.2 and all necessary libav* libraries are installed on my Ubuntu 14.04 machine. However, when I try to install OpenCV 2.4.11 (with FFMpeg enabled), I get the following error :

    /usr/bin/ld: cannot find -lavcodec
    
/usr/bin/ld: cannot find -lswresample
    
/usr/bin/ld: cannot find -lavutil
    
/usr/bin/ld: cannot find -lavformat
    
/usr/bin/ld: cannot find -lavcodec
    
/usr/bin/ld: cannot find -lswresample
    
/usr/bin/ld: cannot find -lavutil
    
/usr/bin/ld: cannot find -lavformat
    
collect2: error: ld returned 1 exit status
    
make[2]: *** [bin/opencv_annotation] Error 1
    
make[1]: *** [apps/annotation/CMakeFiles/opencv_annotation.dir/all] Error 2
    
make: *** [all] Error 2

    I already tried pointing LD_LIBRARY_PATH and PKG_CONFIG_PATH to the locations which contain the FFmpeg libraries. I also tried with OpenCV 3.0 and obtained the same error.

    It seems that there is some kind of incompatibility between these versions of FFMpeg and OpenCV. Is there a workaround for this ?

    EDIT :
    For example locate libavcodec.a outputs :

    /home/guel/cvpr2014/bin/dependencies/ffmpeg-2.4/libavcodec/libavcodec.a
    
/home/guel/cvpr2014/bin/dependencies/lib/libavcodec.a
    
/home/guel/cvpr2014/bin/dependencies/opencv-2.4.9/3rdparty/lib/libavcodec.a
    
/home/guel/ffmpeg_build/lib/libavcodec.a
    
/home/guel/git/ffmpeg/libavcodec/libavcodec.a
    
/home/guel/mplayer/ffmpeg/libavcodec/libavcodec.a
    
/home/guel/projects/mpegflow/dependencies/opencv-2.4.11/3rdparty/lib/libavcodec.a

    So, I have it in multiple places. Is that bad ?
