HTML5 audio and video support

13 avril 2011, par kent1

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 (...)
De l’upload à la vidéo finale [version standalone]

31 janvier 2010, par kent1

Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
Upload et récupération d’informations de la vidéo source
Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

ffmpeg merge wav-audio and rtmp-video stream with itsoffset parameter ?

2 juillet 2015, par whatis01
I tried to merge WAV audio and RTMP video stream with -itsoffset parameter :
```
ffmpeg -i rtmp://server/video/stream_folder/stream_id -itsoffset 00:00:15.0000 -i /audio/1227121.wav \

-codec:v copy -ac 2 -codec:a aac -strict experimental -f flv rtmp://server/sfolder/test_1
```
But it works inappropriately (RTMP output is not steady, only voice or only video), and always prompts : mux overhead ratio 2000%, then conversion failed.

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 :

ffmpeg trim .mp3 - output length forced to 2 seconds

22 septembre 2015, par Brooks

I have just downloaded the latest version of ffmpeg and I am trying to trim the first 14 and the last 6 seconds from a 40 seconds .mp3 file.

The problem I have is that doesn’t matter what -t X I use, the output is always only 2 seconds in length. It’s my first using ffmpeg but it seems like something is forcing it to limit the output to 2 seconds.

I tried a lot of commands including

ffmpeg -ss 00:00:14.358 -i input.mp3 -ab 32k -t 00:00:20.04 -c:a copy output.mp3 -y



ffmpeg -ss 14 -i input.mp3 -ab 32k -t 20 -c:a copy output.mp3 -y



ffmpeg -ss 14 -i input.mp3 -t 20 -acodec copy output.mp3 -y



ffmpeg -ss 14 -i input.mp3 -acodec copy output.mp3 -y



ffmpeg -ss 14 -t 20 -i input.mp3 output.mp3



ffmpeg -ss 14 -i input.mp3 -t 20 output.mp3

but the result is almost always a 2 sec mp3 file.
Now I’m out of ideas.

As requested this is the output from the console :
