在上篇博客我们介绍的是runtimeutils文件。今天我们将介绍我们是如何获取音视频信息，并将修改好的音视频信息值返回的相关知识。

在解释相关代码之前，我们需要清楚一个视频或者音频有许多例如宽,高,duration等等常用信息。我们需要对这些相关信息进行获取。在这个项目中我们用的是相关info方法。例如我们使用的VideoInfo和AudioInfo和FFmpegInfo文件。用的方法一致。只不过是获取的对应参数不同。

AudioInfo

package com.whty.zdxt.multimedia.pojo;

public class AudioInfo {
    // 音频 编码名称
    private String codecName;

    // 音频 audio
    private String codecType;

    // 音频 时长
    private String duration;

    // 音频 比特率
    private Integer bitRate;

    // 音频 采样率
    private Integer sampleRate;

    // 音频 声道数 1：单声道 2：双声道
    private Integer channels;

    public String getCodecName() {
        return codecName;
    }

    public void setCodecName(String codecName) {
        this.codecName = codecName;
    }

    public String getCodecType() {
        return codecType;
    }

    public void setCodecType(String codecType) {
        this.codecType = codecType;
    }

    public String getDuration() {
        return duration;
    }

    public void setDuration(String duration) {
        this.duration = duration;
    }

    public Integer getBitRate() {
        return bitRate;
    }

    public void setBitRate(Integer bitRate) {
        this.bitRate = bitRate;
    }

    public Integer getSampleRate() {
        return sampleRate;
    }

    public void setSampleRate(Integer sampleRate) {
        this.sampleRate = sampleRate;
    }

    public Integer getChannels() {
        return channels;
    }

    public void setChannels(Integer channels) {
        this.channels = channels;
    }

    @Override
    public String toString() {
        return "AudioInfo [" +
                "codecName=" + codecName +
                ", codecType=" + codecType +
                ", duration=" + duration +
                ", bitRate=" + bitRate +

    }
}

VideoInfo

    // 视频 帧率

    // 视频 比特率
    private Integer bitRate;

    // 视频 总帧数
    private Integer nbframes;

    public String getCodecName() {
