来自.ts文件的Java BufferedImages

Question

如何从Java中的.ts文件获取BufferedImage（定义位置的帧）？如果可能，我不想使用任何JNI / CLI包装器。

＆＃13;

＆＃13;

     System.out.println( JCodecUtil.detectFormat( file ) );
        Demuxer demuxer = JCodecUtil.createDemuxer( JCodecUtil.detectFormat( file ), file );
        for ( DemuxerTrack demuxerTrack : demuxer.getVideoTracks() ) {
            Packet packet;
            while ( ( packet = demuxerTrack.nextFrame() ) != null ) {
                System.out.println( "frame " + packet.getDuration() );
            }
        }

＆＃13;

＆＃13;

＆＃13;

第一个代码段的输出只是MPEG_TS [ERROR] . (:0): Format MPEG_TS is not supported MPEG_TS [ERROR] . (:0): Format MPEG_TS is not supported

＆＃13;

＆＃13;

    for ( DemuxerTrack demuxerTrack : JCodecUtil.createM2TSDemuxer( file, TrackType.VIDEO ).v1.getTracks() ) {
        Packet packet;
        while ( ( packet = demuxerTrack.nextFrame() ) != null ) {
            System.out.println( "frame : " + ImageIO.read( new ByteArrayInputStream( packet.getData().array() ) ) );
        }
    }

＆＃13;

＆＃13;

＆＃13;

在这个Snippet中，它只为每个帧输出null。如何解决这个问题？

Answer 1

Picture tmp = Picture.create(1920, 1088, ColorSpace.YUV420);
VideoDecoder vd = JCodecUtil.createVideoDecoder(JCodecUtil.detectDecoder(data.duplicate()), data.duplicate());
Picture pic = vd.decodeFrame(data, tmp.getData());
BufferedImage buf = AWTUtil.toBufferedImage(pic);
