iknow4 / android-video-trimmer

Android-Video-Trimmer项目实现了对长短视频进行片段的裁剪选择。使用MediaMetadataRetriever获取视频帧，采用ffmpeg进行视频裁剪，和视频压缩。

项目介绍

实现Android上使用ffmpeg进行视频裁剪，压缩功能。类似视频裁剪功能的开源项目,个人觉得非常稀缺。 不像ios开源的那么多,自己在开发过程中也是不断的摸索,其中也遇到不少蛋疼的问题。 现在简单说一下这个项目实现。

使用到相关技术

• FFmpeg实现裁剪视频
• FFmpeg实现裁剪之后的视频压缩
• 采用Loader或者ContentProvider获取所有视频资源
• 采用VideoView播放视频
• 采用RecycleView显示视频的帧图片
• 通过MediaMetadataRetriever获取视频帧的Bitmap
• View的自定义

功能扩展思考

视频裁剪功能之后往往涉及到视频的压缩和上传,每一个功能都是Android开发中的高阶内容,比如说视频的压缩,压缩库其实开源的有一些, 但是能达到压缩比高、压缩速度快,同时又保证视频的质量,这样的开源库还是比较少的。 在这个项目中，我只是简单的实现了裁剪后的视频压缩，想达到一个好的压缩效果，还需要在项目中对视频压缩参数进行调整， 大家可以fork项目进行相应的移植和修改。

其他

• 视频裁剪完成，会将裁剪好的视频输出保存至应用的Android->data->包名->cache文件夹中
• 联系方式 Email: [email protected] WeChat: 516799851

欢迎star、fork和issues.

有些许问题

先膜拜下大神。 再提点小问题。
at com.iknow.android.widget.RangeSeekBarView.onDraw(RangeSeekBarView.java:156)，这里划着划着就oom了。有的手机大于30S的视频帧就显示不出来了，整体感觉卡顿卡顿的。

bitmap 为空

在小米5手机压缩出现压缩失败

小米手机5,Android 8.0,26.但是出现compress video failed

剪辑的时候 锁屏 在解锁 所剪裁的视频时长会变长 。设置剪裁时间 截图会比较模糊。

推荐换个速度还可以的ffmpeg库

速度快还能中断转码，https://github.com/mengzhidaren/FFmpegCmdSdk

老铁，这么多分支，那个是最新维护的呢

4.4系统版本RangeSeekBarView拖动左边和右边的托块之后无法绘制阴影遮盖，不知道是什么原因

视频合成

老铁，能做一个视频合成，加水印的demo吗？
谢谢

Reset

I have implemented your code, It works great. But I need to refresh all the component once I changed the video. Here I changed VideoTrimmerview, recycle Adapter but cant refreshing RangeSeekBarView. Please help us.

退出后台再进会出现重复 或者前面留白

这个的初始化应该只能一次

裁剪时间过长，压缩视频比裁剪的视频还大？

1.看了下closed的问题，基本提到的是压缩时间，我感觉裁剪时间过长，问题比较大。15秒的视频裁剪8秒需要25s＋的时间。
2. 压缩后的视频大小比裁剪后的还要大一点。(...why)

滑动的时候有Bug

测试一个 02:47的视频，先拖到图片最后面，再拖到最前面，最前只能到00:29就不能再往前了，实际显示图片倒是00:00的。这个Bug还请麻烦看看哈

下面的缩略图显示不出来

视频裁剪3分钟的视频，下面的缩略图出不来

android.view.InflateException: Binary XML file line #9: Error inflating class com.example.VideoTrimmerView

How to use this view in my app.It's generated android.view.InflateException: Binary XML file line #9: Error inflating class com.example.VideoTrimmerView this error.

支持MKV格式的视频的裁剪吗

支持MKV格式的视频的裁剪吗

裁剪时间不一致

裁剪出来的视频有时候11秒，有时候13秒。。。。

需要精确裁剪的拿走不谢

double startTime = (double)startMs / 10.0D / 10.0D / 10.0D;
double induration = (double)(endMs - startMs) / 10.0D / 10.0D / 10.0D;
String[] complexCommand = new String[]{"ffmpeg", "-ss", "" + startTime, "-y", "-i", inputFile, "-t", "" + induration, "-vcodec", "mpeg4", "-b:v", "2097152", "-b:a", "48000", "-ac", "2", "-ar", "22050", outputFile};
FFmpegCmd.exec(complexCommand, 0L, new OnEditorListener() {
public void onSuccess() {
callback.onFinishTrim(outputFile);
}

        public void onFailure() {
            callback.onFailed();
        }

        public void onProgress(float progress) {
            Log.d(TrimVideoUtil.TAG, "FAILED with onProgress : " + progress);
        }
    });

裁剪框不能拖到最后

例如一个视频有22秒，只能选择裁剪前面19s的内容，最后几秒裁剪框不能拖动到那里

点击截取完成后直接崩溃

oppo A59m

三星手机裁剪视频失败，”正在裁剪视频“Dialog长时间不消失

手机信息描述：

初步原因：

怎么会把相册里面的图片的时长也裁剪了?

视频372M 时长三分半 加载的时候就ANR了 ，请问这个怎么解决

将时间精确到0.1秒为单位的裁剪

如果我将时间改为每次裁剪区域时间为60秒
裁剪时间精确到毫秒的话
发现拖动右边进度条的准确有问题
不是很清楚这块的算法

迫不得已自己加了没有完美的减去了一定的宽度，精确度提高了解决了我的问题 不过不知道是哪里造成的误差 左边的没有这个问题

i didn't change anything else than imports to make them work in my project.

Trimming process never succeeds

I just downloaded your project and trimmed a video.

Looks like the process never succeeds, the alert dialog never hides.

By the way, the UI for trimming looks really cool

符号: 类 ActivityRecordingLayoutBinding

为什么红色的光标与拖拽控件有一定的间隔

这是一个一直存在的bug，没有时间修复，我后面计划用FFmpeg来重新实现整个项目

setMaxDuration不是15秒就不对

抱歉 回复晚了。
问题已经修复，现在视频裁剪的时间，由TrimVideoUtil.java类中的变量VIDEO_MAX_DURATION来统一控制。

请更新最新代码。
非常感谢！

ffmpeg总感觉压缩时间太慢了，如果只需要用到压缩的话，推荐

我推荐一个压缩更加快的，https://github.com/tangpeng/VideoCompressor 一个5分钟的视频，大小为646M 压缩时间3分钟

Avi files with codec MjPEG throws FIle not found exception
