问题:原视频的编码格式为h265,在小程序上面无法播放,需要转为mpeg-4格式。
1、引入相关依赖
<dependency>
<groupid>org.bytedeco</groupid>
<artifactid>javacv</artifactid>
<version>1.4.1</version>
</dependency>
<dependency>
<groupid>org.bytedeco</groupid>

2、视频转码工具类
import org.bytedeco.javacv.frame;
import org.bytedeco.javacpp.avcodec;
import org.bytedeco.javacv.framegrabber;
import org.bytedeco.javacv.framerecorder;
import org.bytedeco.javacv.ffmpegframegrabber;
import org.bytedeco.javacv.ffmpegframerecorder;
/**
* 视频转码工具类
*/
public class videoconvertutil {
public void convert(string inputfile, string outputfile) throws exception {
ffmpegframegrabber grabber = ffmpegframegrabber.createdefault(inputfile);
frame captured_frame;
ffmpegframerecorder recorder = null;
try {
grabber.start();
recorder = new ffmpegframerecorder(outputfile, grabber.getimagewidth(), grabber.getimageheight(), grabber.getaudiochannels());
recorder.setvideocodec(avcodec.av_codec_id_mpeg4);
recorder.setformat("mp4");
recorder.setframerate(grabber.getframerate());
recorder.setsamplerate(grabber.getsamplerate());
recorder.setvideobitrate(grabber.getvideobitrate());
recorder.setaspectratio(grabber.getaspectratio());
recorder.setaudiobitrate(grabber.getaudiobitrate());
recorder.setaudiooptions(grabber.getaudiooptions());
recorder.setaudiocodec(avcodec.av_codec_id_aac);
recorder.start();
while (true) {
captured_frame = grabber.grabframe();
if (captured_frame == null) {
system.out.println("转码完成");
break;
}
recorder.record(captured_frame);
}
} catch (framerecorder.exception e) {
e.printstacktrace();
} finally {
if (recorder != null) {
try {
recorder.close();
} catch (exception e) {
system.out.println("recorder.close异常" + e);
}
}
try {
grabber.close();
} catch (framegrabber.exception e) {
system.out.println("framegrabber.close异常" + e);
}
}
}
}
3、调用工具类方法
videoconvertutil convertutil = new videoconvertutil();
convertutil.convert(url, videosavepath);
