  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • 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 :

  • Using ffmpeg to combine small mp4 chunks ?

    20 mai 2015, par shiny formica

    I’m trying to convert batches of png images into a single mp4 x264 video using ffmpeg. The conversion, for reasons I won’t go into, converts groups of frames into short mp4 chunks and then I want to take those chunks and merge them into the final video at a specific fps (in this case 30fps).

    My understanding of ffmpeg and the x264 options is too limited, and while I can produce the individual mp4 chunks from the source png frames without trouble, the final merge always ends up duplicating and/or dropping frames especially with very short chunks (< 4 frames).

    The conversion from png to mp4 uses this command :

    ffmpeg -start_number 1001 -framerate 30 -f image2 -i 'intermediate.%d.png' -c:v libx264 -crf 1 -pix_fmt yuv420p -movflags +faststart -frames:v 4 -r 30 chunk.1.mp4 -y

    which appears to work as expected, I get a playable mp4 chunk of, in this case, 4 frames of the sequence of png images at 30fps. The length of each chunk can be anywhere from 1 frame to around 100 frames.

    When all the chunks are generated, I’ve been trying to use the concat demuxer to combine without re-encoding, placing all the source chunk paths in a file :

    concat.txt :

    file 'chunk.1.mp4'
    file 'chunk.2.mp4'
    file 'chunk.3.mp4'
    ...

    and then running this ffmpeg command :

    ffmpeg -f concat -i concat.txt -c:v copy merged.mp4 -y

    but it says this during the concatenation :

    [concat @ 0x315ff80] Estimating duration from bitrate, this may be inaccurate

    and the resulting mp4 has dropped/duplicated frames. So I tried adding duration info to the concat.txt file :

    file 'chunk.1.mp4'
    duration 0.133333
    file 'chunk.2.mp4'
    duration 0.133333
    file 'chunk.3.mp4'
    duration 0.066666

    in this case, two 4-frame/30fps chunks and one 2-frame/30fps chunk. Which gets rid of that estimation warning, but the result is still duplicating/dropping frames.

    I’m not sure where I’m going wrong here...what do I need to do either in the production of the short mp4 segments, or in the combination stage, to get a single mp4 at the right framerate with no duplicated or dropped frames ?

    As suggested, here’s the console output for the conversion from png->mp4 chunks :

    ffmpeg -loglevel verbose -start_number 1001 -framerate 30 -f image2 -i 'intermediate.%d.png' -c:v libx264 -crf 1 -pix_fmt yuv420p -movflags +faststart -frames:v 4 -r 30 chunk.1.mp4 -y

    as I said, this appears to produce a valid mp4 at 30fps with no duplicated or dropped frames from the input images.

  • FFMPEG with SSM is not using the specified network interface

    23 janvier 2014, par caspar

    I'm trying to use ffmpeg/ffprobe to join a SSM stream on a server with multiple network interfaces. I'm using the following command to initialize the input :

    c:\ffmpeg\bin>ffprobe "udp://232.2.4.206:24206?localaddr=10.15.248.217&amp;sources=10.15.248.210,10.15.248.211,10.15.248.212,10.15.248.213&amp;connect=1&amp;fifo_size=1000000" -v 9 -loglevel 99

    The routing on the server can't be changed, though I can confirm other applications running on the same server are able to join and receive the multicast signal. The issue is, I believe, with the localaddr parameter, which is ignored it seems. Using Wireshark I can see that the wrong interface is being used (i.e. not the 10.15.248.217 interface).

    The output of the above command is :

    Anyone have experience with this use case ? Perhaps this is a bug that needs raising ?

    EDIT : I found out that if I remove the &amp;sources= parameter, the localaddr is used and the request is passed through the correct interface, however as I need to join a SSM stream, this still blocks me from continuing.
