Support audio et vidéo HTML5
10 avril 2011MediaSPIP 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.

JavaCV Video Player with FFmpeg and JavaFx
2 juin 2021, par ِِYazdan NaderiI want to create a media player using Java CV, but I can not adjust the frame rate
And because of this, some videos play fast and some play slow


Is it possible to read the information of a video through a FFmpegFrameGrraber object and set it in another object to solve the problem ?
Of course, I did this and did not get an answer, but if there is another way, please help


playThread = new Thread(new Runnable() {
 public void run() {
 try {
 final String videoFilename = "E:\\Java\\s1\\3.mp4";
 final String videoFilename2 = "E:AudioVideo.mp4";
 final String videoFilename3 = "E:\\1.mp4";
 final String videoFilename4 = "E:\\Java\\s1\\3.mp4";


 FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(videoFilename);



 grabber.start();

 grabber.setFrameRate(30.00);


 primaryStage.setWidth(grabber.getImageWidth());
 primaryStage.setHeight(grabber.getImageHeight());

 final AudioFormat audioFormat = new AudioFormat(grabber.getSampleRate(), 16, grabber.getAudioChannels(), true, true);

 final DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat);
 final SourceDataLine soundLine = (SourceDataLine) AudioSystem.getLine(info);
 soundLine.open(audioFormat);
 soundLine.start();

 JavaFXFrameConverter converter = new JavaFXFrameConverter();

 ExecutorService executor = Executors.newSingleThreadExecutor();

 while (!Thread.interrupted()) {
 Frame frame = grabber.grab();
 if (frame == null) {
 break;
 }
 if (frame.image != null) {
 final Image image = converter.convert(frame);//
 Platform.runLater(() -> {
 
 imageView.setImage(image);

 });
 }
 else if (frame.samples != null) {
 final ShortBuffer channelSamplesShortBuffer = (ShortBuffer) frame.samples[0];
 channelSamplesShortBuffer.rewind();

 final ByteBuffer outBuffer = ByteBuffer.allocate(channelSamplesShortBuffer.capacity() * 2);

 for (int i = 0; i < channelSamplesShortBuffer.capacity(); i++) {
 short val = channelSamplesShortBuffer.get(i);
 outBuffer.putShort(val);
 }

 try {



 executor.execute(() -> {
 soundLine.write(outBuffer.array(), 0, outBuffer.capacity());
 outBuffer.clear();
 });
 } catch (Exception interruptedException) {
 Thread.currentThread().interrupt();
 }
 }

 }
 executor.shutdownNow();
 executor.awaitTermination(10, TimeUnit.SECONDS);

 soundLine.stop();
 grabber.stop();
 grabber.release();
 Platform.exit();
 } catch (Exception exception) {
 LOG.log(Level.SEVERE, null, exception);
 System.exit(1);
 }
 }
 });
 playThread.start();
 }

Flutter ffmpeg_kit_flutter_full_gpl-6.0.3 PluginRegistry.Registrar flutter version 3.29
30 avril, par LisaI am using ffmpeg_kit_flutter_full_gpl-6.0.3 for flutter version 3.27 but when upgrading to flutter 3.29, with android, there is an error PluginRegistry.Registrar registrar. Is there any solution to replace the current
ffmpeg_kit_flutter_full_gpl
because I see this library was updated 17 months ago

Joining three videos with FFMpeg [duplicate]
4 novembre 2016, par M. SaezThis question is an exact duplicate of :
I’m trying to merge/join three mp4 videos with ffmpeg ; the first one is a 5 seconds intro without an audio track, then it is the main video and at the end there is a 6 seconds mp4 video also without an audio track.
All videos are encoded with exactly the same settings, so far i’m trying the concat option and i can join them just fine, the problem is the final video doesn’t have the audio track from the main video.
This is the command i’m using :
ffmpeg -f concat -i mylist.txt -c copy output.mp4
Needless to say, the final video must respect the first 5 seconds without audio and the last 6 seconds.
Any idea ?, if i prefer something where i don’t need to reencode at all, but if i must, i don’t really mind.
Thanks !
