    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Why my ffmpeg libs are so large ? [on hold]

    9 avril 2014, par user3504221

    I compiled ffmpeg libs on my Ubuntu 64-bits using the following script :

       mkdir ~/ffmpeg_sources

    #x264

    cd ~/ffmpeg_sources
    
   wget http://download.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
    
   tar xjvf last_x264.tar.bz2
    
   cd x264-snapshot*
    
   ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static --disable-asm
    
   make
    
   make install
    
   make distclean

    #FFmpeg

    cd ~/ffmpeg_sources
    
   wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
    
   tar xjvf ffmpeg-snapshot.tar.bz2
    
   cd ffmpeg
    
   PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig"
    
   export PKG_CONFIG_PATH
    
   ./configure --prefix="$HOME/ffmpeg_build" --extra-cflags="-I$HOME/ffmpeg_build/include" \
    
   --extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin" --extra-libs="-ldl" --   enable-gpl \
    
  --enable-libx264 --enable-x11grab --disable-yasm                                                                                                                               
    
   make
    
   make install
    
   make distclean
    
   hash -r

    But the final libs are really large (For example, libavcodec.a > 140 Mb). Anybody know why my libs are so large ?

    EDIT

    My Solutions :

    • add the option "—disable-debug" to the ./configure. The size of my libavcodec fell from 150Mb to 12Mb !
    • Remove all unnecessary codecs : Add the options -disable-encoders, —disable-decoders and then add only codecs you want with —enable-encoder=NAME and —enable-decoder=NAME. Print the list using ./configure —list-encoders —list-decoders. see ./configure —help for more information. (My final libavcodec has a size of 4Mo)

  • Combine Image and Audio AND fade in and out

    7 janvier 2024, par Jake

    I have an ffmpeg command that merges 1 image and 1 audio file, but I also want the output video to have a fade in and fade out, how can I do that ?

    


    Here's the command :
ffmpeg -r 1 -loop 1 -i image.jpg -i audio.mp3 -acodec copy -r 1 -shortest -vf scale=1280:720 final.mp4

    


  • FFMPEG Video Multiplexer [closed]

    24 janvier, par Nader

    I am a DirectShow developer, I used to build multiplexers that take 2 video inputs and generate one output, I would then use a video encoder mux to feed it the output + anothrr audio stream to generate the final video output. The multiplexer (DirectShow framework) allows me to process the input video from two sources (for example, adding effects using the two frames).

    


    How can this can be done using FFMPEG ?
