  • Librairies et logiciels spécifiques aux médias

    10 décembre 2010, par

    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
    Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles.

  • ffmpeg recognises MXF dv but won't encode to h264

    6 août 2017, par 3pointedit

    I have a DV file encoded as an MXF that I want to transcode to h264. Running ffmpeg against the file it reads ok and understands the stream but won’t write the h264 file. It seems to get all the streams correct and I can confirm the attributes of video and audio streams.

    I just don’t understand why it won’t encode ? I tried to force a Decoder with -f dv but it complained that the source header was incorrect.

     ./ffmpeg -f dv -i camb_onitefire_050914.mov  camb_onitefire_A.mp4

  • ffmpeg won't recognize x265 options [closed]

    29 octobre 2017, par cdpp

    I am trying to use ffmpeg’s built-in x265 library to process .VOB files through h.265codec.

    What I understood from the ffmpeg documentation was that :

    -c:v libx265 tells ffmpeg to use the h.265 codec for video streams

    -x265-params passes options to x265 encoder instead of ffmpeg

    But whenever try to run the command, ffmpeg doesn’t seem to recognize/pass the options to x265.

    It gives the error

    Unrecognized option '-y4m'.<br />
    Error splitting the argument list: Option not found

    Why is this ?

    Here’s the command (edited spacing) :

    C:\ffmpeg (20170123-e371f03-win64-static)\bin>

  • Android - Decoding via a pipe will not work : Could not find an ffmpeg binary for your system

    28 août 2017, par Daniele

    I’m trying to use TarsosDSP for real time pitch shifting on Android.

    This is my code :

    Uri song;
    
// initialized in another method
    

    
double rate = 1.0;
    
        RateTransposer rateTransposer;
    
        AudioDispatcher dispatcher;
    
        WaveformSimilarityBasedOverlapAdd wsola;
    

    
        dispatcher = AudioDispatcherFactory.fromPipe(getRealPathFromUri(song), 44100, 5000, 2500);
    
        rateTransposer = new RateTransposer(rate);
    
        wsola = new WaveformSimilarityBasedOverlapAdd(WaveformSimilarityBasedOverlapAdd.Parameters
    
                .musicDefaults(rate, 44100));
    

    
        wsola.setDispatcher(dispatcher);
    
        dispatcher.addAudioProcessor(wsola);
    
        dispatcher.addAudioProcessor(rateTransposer);
    
        dispatcher.addAudioProcessor(new AndroidAudioPlayer(dispatcher.getFormat()));
    
        dispatcher.setZeroPadFirstBuffer(true);
    
        dispatcher.setZeroPadLastBuffer(true);

    I get an error here

    dispatcher = AudioDispatcherFactory.fromPipe(getRealPathFromUri(song), 44100, 5000, 2500);

    Decoding via a pipe will not work : Could not find an ffmpeg binary for
    your system

    Why does this happen and how should I fix it ?

    EDIT :

    As far as I was able to understand it’s because ffmpeg isn’t integrated within the app. I looked for a guide here on SO but I couldn’t find any updated one. Using NDK r15c and FFmpeg 3.3.3
