Android录制视频---LandscapeVideoCamera的使用详情及修改

来源：互联网发布：苹果软件更新编辑：程序博客网时间：2024/05/16 08:35

LandscapeVideoCamera是一个非常强大的android 视频录制库，可以选择视频尺寸以及视频质量，只允许横屏录制。对于LandscapeVideoCamera的好处就不多介绍了。网上已经有很多人介绍了

个人最忍受不了一个点是：强制用户横屏，竖屏的时候是不让录制的，这一点真的有点坑，录制过程中不小心斜过来了呢？它就停了！它就停了！它就停了！（个人体验，不否认LandscapeVideoCamera本身的强大~~~）

......

因项目需求原因对其进行了如下修改：

1：取消了竖屏时停止录制的动作。

2：录制结束后增加了重录功能。

3：增加了倒计时开始录制功能。

4：增加了录制过程中开启灯光的功能。

5：需求原因改变了其UI。

CaptureConfiguration对象有多种构造方式如下：

private CaptureConfiguration() {        // Default configuration    }    @Deprecated    public CaptureConfiguration(CaptureResolution resolution, CaptureQuality quality) {        videoWidth = resolution.width;        videoHeight = resolution.height;        bitrate = resolution.getBitrate(quality);    }    @Deprecated    public CaptureConfiguration(CaptureResolution resolution, CaptureQuality quality, int maxDurationSecs,                                int maxFilesizeMb, boolean showTimer) {        this(resolution, quality, maxDurationSecs, maxFilesizeMb, showTimer, false);        this.showTimer = showTimer;    }    @Deprecated    public CaptureConfiguration(CaptureResolution resolution, CaptureQuality quality, int maxDurationSecs,                                int maxFilesizeMb, boolean showTimer, boolean allowFrontFacingCamera) {        this(resolution, quality, maxDurationSecs, maxFilesizeMb);        this.showTimer = showTimer;        this.allowFrontFacingCamera = allowFrontFacingCamera;    }    @Deprecated    public CaptureConfiguration(CaptureResolution resolution, CaptureQuality quality, int maxDurationSecs,                                int maxFilesizeMb, boolean showTimer, boolean allowFrontFacingCamera,                                int videoFPS) {        this(resolution, quality, maxDurationSecs, maxFilesizeMb, showTimer, allowFrontFacingCamera);        videoFramerate = videoFPS;    }    @Deprecated    public CaptureConfiguration(CaptureResolution resolution, CaptureQuality quality, int maxDurationSecs,                                int maxFilesizeMb) {        this(resolution, quality);        maxDurationMs = maxDurationSecs * MSEC_TO_SEC;        maxFilesizeBytes = maxFilesizeMb * MBYTE_TO_BYTE;    }    @Deprecated    public CaptureConfiguration(int videoWidth, int videoHeight, int bitrate) {        this.videoWidth = videoWidth;        this.videoHeight = videoHeight;        this.bitrate = bitrate;    }    @Deprecated    public CaptureConfiguration(int videoWidth, int videoHeight, int bitrate, int maxDurationSecs, int maxFilesizeMb) {        this(videoWidth, videoHeight, bitrate);        maxDurationMs = maxDurationSecs * MSEC_TO_SEC;        maxFilesizeBytes = maxFilesizeMb * MBYTE_TO_BYTE;    }

本文中使用的是：

@Deprecated    public CaptureConfiguration(CaptureResolution resolution, CaptureQuality quality, int maxDurationSecs,                                int maxFilesizeMb, boolean showTimer, boolean allowFrontFacingCamera) {        this(resolution, quality, maxDurationSecs, maxFilesizeMb);        this.showTimer = showTimer;        this.allowFrontFacingCamera = allowFrontFacingCamera;    }

resolution对应值有：

RES_360P(WIDTH_360P, HEIGHT_360P, BITRATE_HQ_360P, BITRATE_MQ_360P, BITRATE_LQ_360P),            // LDRES_480P(WIDTH_480P, HEIGHT_480P, BITRATE_HQ_480P, BITRATE_MQ_480P, BITRATE_LQ_480P),            // SDRES_720P(WIDTH_720P, HEIGHT_720P, BITRATE_HQ_720P, BITRATE_MQ_720P, BITRATE_LQ_720P),        // HD readyRES_1080P(WIDTH_1080P, HEIGHT_1080P, BITRATE_HQ_1080P, BITRATE_MQ_1080P, BITRATE_LQ_1080P),    // HDRES_1440P(WIDTH_1440P, HEIGHT_1440P, BITRATE_HQ_1440P, BITRATE_MQ_1440P, BITRATE_LQ_1440P),    // 2KRES_2160P(WIDTH_2160P, HEIGHT_2160P, BITRATE_HQ_2160P, BITRATE_MQ_2160P, BITRATE_LQ_2160P);    // 4K

quality对应值有：

public enum CaptureQuality {        LOW, MEDIUM, HIGH;    }

maxDurationSecs为录制的最长时间，单位为秒。maxFilesizeMb为录制的最大大小，单位为M。showTimer为是否显示录制计时器。allowFrontFacingCamera为是否允许前置摄像头切换。
