2.2、海康视频解析

2.3、比对工具

3、转码

3.1、maven依赖

3.2、实现代码

4、验证

在前面的文章（海康威视-按时间下载录像文件_海康威视 sdk 下载录像 大小0-CSDN博客）中，通过按时间段下载指定的录像视频。

在实际的播放中，VLC工具可以播放，而放到浏览器中则无法播放

1、播放异常比对

海康视频播放错误：

出现 206 返回码，则视频下载完成，无法播放

普通视频播放正常：

虽然出现206，但播放正常。

所以考虑到，可能是通过设备网络SDK下载的视频编码存在问题

2、视频编码检查

使用ffprobe工具进行视频的详细内容检查

复制代码 
ffprobe.exe  -v quiet -print_format json -show_format -show_streams 3.mp4

2.1、正常视频解析

2.3、比对工具

使用BCompare 比对工具，检查两个json的差异性。共有三处主要的不同

左边为正常视频、右边为海康视频

第一处：

海康转码后的格式 MPEG-H Part2/HEVC(H.265)(hevc)

第二处：

第三处：

3、转码

通过上图的对比，优先考虑将海康视频转码为H.264 格式

3.1、maven依赖

复制代码 
<dependency>
            <groupId>ws.schild</groupId>
            <artifactId>jave-core</artifactId>
            <version>2.4.5</version>
        </dependency>
        <!--    核心包-->
        <dependency>
            <groupId>ws.schild</groupId>
            <artifactId>jave-native-win64</artifactId>
            <version>2.4.5</version>
        </dependency>
        <!--   这个是在windows环境下的jar,使用不同的环境，会调用不同的jar文件-->
        <dependency>
            <groupId>ws.schild</groupId>
            <artifactId>jave-native-linux64</artifactId>
            <version>2.4.5</version>
        </dependency>
        <!--   这个是在linux环境下的jar-->

3.2、实现代码

复制代码 
public static void convertH264() throws EncoderException {
        //源视频位置
        File file = new File("G:\\video\\ffmpeg\\3.mp4");
        //目标视频位置
        File file1 = new File("G:\\video\\ffmpeg\\4.mp4");
        // 创建转码器
        AudioAttributes audio = new AudioAttributes();
        //指定编码
        audio.setCodec("aac");
        audio.setBitRate(new Integer(128000));
        //通道
        audio.setChannels(new Integer(2));
        audio.setSamplingRate(new Integer(44100));
        VideoAttributes video = new VideoAttributes();
        //设置编解码器
        video.setCodec("h264");
        video.setX264Profile(VideoAttributes.X264_PROFILE.BASELINE);
        video.setBitRate(new Integer(1024*1024 * 2));
        //设置帧率
        video.setFrameRate(new Integer(25));
        //设置大小
        //video.setSize(new VideoSize(2560, 1440));
        EncodingAttributes attrs = new EncodingAttributes();
        //格式
        attrs.setFormat("mp4");
        //attrs.setAudioAttributes(audio);
        attrs.setVideoAttributes(video);
        // 进行转码
        Encoder encoder = new Encoder();
        encoder.encode(new MultimediaObject(file), file1, attrs);
    }

根据实际需要设置转码中是否需要音频，

调整视频清晰度：通过设置 video.setBitRate 大小，实际测试值为1024*1024*4=4M大小较清晰。

但是转码时间较长，10秒的3.7M视频 需要7秒转换完成，最终大小4.3M

4、验证

转码后视频可以通过浏览器播放。对应的视频详情如下
