  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    12 avril 2011, par

    La manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
    Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • How to add audio to video file at a specific time using ffmpeg

    7 avril 2017, par LEM

    I have an avi and a wav file. Let’s suppose the video file is one hour long, and the audio file 30 minutes long and it’s associated with the last 30 minutes of the video file.

    Is there a way to create a new video file with the video and audio combined but audio starting after the first 30 minutes of the video ?

  • iOS FFMPEG encode images to video

    10 avril 2013, par brad.roush

    I am trying to take a set of UIImages and create a video file out of them with FFMPEG. Seems there are lots of questions about this topic but non have been able to get this working correctly for me. This one was particularly helpful in giving me a starting point. This iFrameExtractor example was also very helpful but I want to do this in reverse, then add audio.

    This is the closest I have gotten and it creates a short silent video with flashing colors and no images :

    // Register all formats and codecs
    av_register_all();

    AVCodec *codec;
    AVCodecContext *c= NULL;

    int i, out_size, size, outbuf_size;
    FILE *file;
    AVFrame *picture;
    uint8_t *outbuf;

    NSLog(@"Video encoding");

    /* find the mpeg video encoder */
    codec = avcodec_find_encoder(CODEC_ID_MPEG2VIDEO);
    if (!codec) {
       fprintf(stderr, "codec not found\n");
       exit(1);
    }

    c= avcodec_alloc_context3(codec);
    picture= avcodec_alloc_frame();

    /* put sample parameters */
    c->bit_rate = 400000;

    c->time_base= (AVRational){1,25};
    c->gop_size = 10; /* emit one intra frame every ten frames */
    c->max_b_frames=1;
    c->pix_fmt = PIX_FMT_YUV420P;

    /* open it */
    if (avcodec_open2(c, codec, nil) < 0) {
       fprintf(stderr, "could not open codec\n");
       exit(1);
    }

    // Put file in place

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *docs_dir = [paths objectAtIndex:0];
    NSString *filePath = [docs_dir stringByAppendingPathComponent:@"test.mpeg"];

    // Seed file
    NSString *sourcePath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"mov"];
    NSError* error = nil;
    if (![[NSFileManager defaultManager] copyItemAtPath:sourcePath toPath:filePath error:&error]) {
       NSLog(@"Test Video creation failed:%@",[error userInfo]);
    } else NSLog(@"Test Video Created");

    const char *filename = [filePath UTF8String];
    file = fopen(filename, "wb");
    if (!file) {
       fprintf(stderr, "could not open %s\n", "filename");
       exit(1);
    }

    /* alloc image and output buffer */

    /* add sequence end code to have a real mpeg file */
    outbuf[0] = 0x00;
    outbuf[1] = 0x00;
    outbuf[2] = 0x01;
    outbuf[3] = 0xb7;
    fwrite(outbuf, 1, 4, file);
    fclose(file);
    free(outbuf);

    avcodec_close(c);
    av_free(c);
    av_free(picture);
    printf("\n");

    Any ideas will be helpful here. If anyone knows of any other good objective-c examples, this would also be great.

  • Android FFMPEG java concat multiple files

    17 juillet 2015, par Kim T

    I’m using a fork of the cordova-plugin-video-editor library :

    https://github.com/jbavari/cordova-plugin-video-editor/pull/13

    Which uses the android-ffmpeg-java library here :

    https://github.com/guardianproject/android-ffmpeg-java

    The out of box cordova plugin example works well to encode a single video using the following code :

    File tempFile = File.createTempFile("ffmpeg", null, appContext.getCacheDir());
    FfmpegController ffmpegController = new FfmpegController(appContext, tempFile);

    TranscodeCallback tcCallback = new TranscodeCallback();

    Clip clipIn = new Clip(videoSrcPath);
    Clip clipOut = new Clip(outputFilePath);
    clipOut.videoCodec = "libx264";
    clipOut.videoFps = "24"; // tailor this to your needs
    clipOut.videoBitrate = 512; // 512 kbps - tailor this to your needs
    clipOut.audioChannels = 1;
    clipOut.width = outputWidth;
    clipOut.height = outputHeight;
    clipOut.duration = videoDuration;
    ffmpegController.processVideo(clipIn, clipOut, true, tcCallback);

    This calls the android-ffmpeg-java code here :

    https://github.com/guardianproject/android-ffmpeg-java/blob/master/src/org/ffmpeg/android/FfmpegController.java#L225

    They have a multiple file concat test example here :

    https://github.com/guardianproject/android-ffmpeg-java/blob/master/src/org/ffmpeg/android/test/ConcatTest.java#L16

    So I have modified the cordova plugin code to match the example :

    ArrayList<clip> listVideos = new ArrayList<clip>();

    Clip clip = new Clip();
    clip.path = new File(videoSrcPath).getCanonicalPath();
    ffmpegController.getInfo(clip);
    clip.duration = 5;
    listVideos.add(clip);

    Clip clip2 = new Clip();
    clip2.path = new File(videoSrcPath2).getCanonicalPath();
    ffmpegController.getInfo(clip2);
    clip2.duration = 5;
    listVideos.add(clip2);

    Clip clipOut = new Clip();
    clipOut.path = new File(outputFilePath).getCanonicalPath();
    ffmpegController.concatAndTrimFilesMP4Stream(listVideos, clipOut, false, false, new ShellUtils.ShellCallback() {
       @Override
       public void shellOut(String shellLine) {
           System.out.println("fc>" + shellLine);
       }
       @Override
       public void processComplete(int exitValue) {
           if (exitValue &lt; 0)
               System.err.println("concat non-zero exit: " + exitValue);
       }
    });
    </clip></clip>

    However when run I get the error :
