Java获取视频参数信息

资料收集

经过搜索常用的处理视频的方式有两种：xuggler 和 ffmpeg

因ffmpeg 需要使用JNI调用，这里采用xuggler方式

使用xuggler获取视频宽、高、时长等信息

以下内容参考这篇文章

引入maven配置 xuggle 依赖 slf4j-api

// first we create a Xuggler container object

IContainer container = IContainer.make();

// we attempt to open up the container

int result = container.open(filename, IContainer.Type.READ, null);

// check if the operation was successful

if (result<0)

throw new RuntimeException("Failed to open media file");

// query how many streams the call to open found

int numStreams = container.getNumStreams();

// query for the total duration

long duration = container.getDuration();

// query for the file size

long fileSize = container.getFileSize();

// query for the bit rate

System.out.println("Number of streams: " + numStreams);

System.out.println("Duration (ms): " + duration);

System.out.println("File Size (bytes): " + fileSize);

System.out.println("Bit Rate: " + bitRate);

// iterate through the streams to print their meta data

for (int i=0; i

// find the stream object

IStream stream = container.getStream(i);

// get the pre-configured decoder that can decode this stream;

IStreamCoder coder = stream.getStreamCoder();

System.out.println("*** Start of Stream Info ***");

System.out.printf("stream %d: ", i);

System.out.printf("type: %s; ", coder.getCodecType());

System.out.printf("codec: %s; ", coder.getCodecID());

System.out.printf("duration: %s; ", stream.getDuration());

System.out.printf("start time: %s; ", container.getStartTime());

System.out.printf("timebase: %d/%d; ",

stream.getTimeBase().getNumerator(),

stream.getTimeBase().getDenominator());

System.out.printf("coder tb: %d/%d; ",

coder.getTimeBase().getNumerator(),

coder.getTimeBase().getDenominator());

System.out.println();

if (coder.getCodecType() == ICodec.Type.CODEC_TYPE_AUDIO) {

System.out.printf("sample rate: %d; ", coder.getSampleRate());

System.out.printf("channels: %d; ", coder.getChannels());

System.out.printf("format: %s", coder.getSampleFormat());

} else if (coder.getCodecType() == ICodec.Type.CODEC_TYPE_VIDEO) {

System.out.printf("width: %d; ", coder.getWidth());

System.out.printf("height: %d; ", coder.getHeight());

System.out.printf("format: %s; ", coder.getPixelType());

System.out.printf("frame-rate: %5.2f; ", coder.getFrameRate().getDouble());

}

System.out.println();

System.out.println("*** End of Stream Info ***");

}

}

}
