视频录制 视频压缩（使用FFMpeg）Android Video Recorder/Video Compressor

VideoRecorderAndCompressor

#version 1.1 #works on 7.0 Video Recorder, also a video compressor using ffmpeg supports resolution selection, you can also modify the command to configure compress parameters(video resolution etc...). Internationalization will be done in a few days.

Use https://github.com/WritingMinds/ffmpeg-android-java to load ffmpeg library and execute compress command.

#初始版本 #7.0不能压缩的问题已解决 视频录制（支持录制分辨率选择）

视频压缩（使用FFMpeg）

使用了 http://writingminds.github.io/ffmpeg-android-java/ https://github.com/WritingMinds/ffmpeg-android-java 的ffmpeg的操作库用于加载ffmpeg的库以及执行命令。

你好，编译后的so文件的编译文件没开源对吧？视频好像没法压缩

你好，编译后的so文件的编译文件没开源对吧？视频好像没法压缩

压缩速率能调快么

压缩比率很完美，可以压缩至原大小的十分之一。但是压缩150M需要大概3分钟，有什么好办法能加快压缩速率么

竖屏录制 电脑播放却旋转了90度

竖屏录制 电脑播放却旋转了90度

视频比例发送变化

录视频和压缩过后的视频。宽高比发生边框，视频明显被压扁

点击后显示摄像头初始化失败？

点击后显示摄像头初始化失败？

ffmpeg有点大

压缩后的视频的width是640，高度是480了，怎么才能让宽高跌倒一下呢

70的报错 CANNOT LINK EXECUTABLE

哥们 7.0 不兼容报错，麻烦弄一下 我这样 菜鸟 想做这功能全靠你呢

没有进度条

怎么显示进度条呢。

视频压缩问题

demo运行不了啊, 可以把视频录制和视频压缩的步骤写详细点吗? 谢谢!!

给了权限还是提示给权限？

一直提示给权限？华为手机？

手机竖屏拍摄,压缩后会旋转的问题

看到有朋友碰到和我一样的问题,我是在使用ffmpeg mp4转ts的时候遇到的,找到了原因,但是一直没有很好的解决方案,大家看一下有没有办法解决
遇到的问题是竖屏状态下拍摄视频,比如设置的是16:9, 1920x1080 拍出来的视频直接打开是正常显示的,但是压缩之后会逆时针旋转90°
原因是在有些机型上,我的是HTC X9 API22 ,系统会限制你的拍摄方向,就算设置了竖向拍摄,拍出来的视频其实是横向的,也就是1080x1920 但是视频有一个参数rotaion,这个参数是90或270,视频在播放是时候会根据这个参数把横向的视频旋转成竖向,所以看上去是竖屏的,但是在压缩转码之后这个rotaion会丢掉变成0,视频就变成旋转过后的样子了.我用系统自带的相机拍了一段视频,发现也是这样的设定,宽大于高,rotaion90.
具体查看参数的代码
MediaMetadataRetriever retr = new MediaMetadataRetriever(); retr.setDataSource("/storage/emulated/0/videokit/in.mp4"); String height = retr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_HEIGHT); // 视频高度 String rotation = retr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_ROTATION); // 视频旋转方向 String width = retr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_WIDTH); // 视频宽度

解决方案试过用ffmpeg设置rotate -i input.m4v -metadata:s:v rotate="90" -codec copy output.m4v 但是不起作用
我目前的办法是用ffmpeg的transpose -i inputfile.mpg -vf transpose=1 outputfile.mpg 逆时针旋转90度再顺时针旋转90度,这样会使原视频的rotation变成0,并且还是竖屏的,但是这个过程很慢,希望大家有更好的方法

android 9.0 华为 p30录制后压缩出现问题

android 9.0 华为 p30录制后压缩出现问题

请问这个压缩ffmpeg文件能不能变小点，因为直接影响打包apk，大10几兆

请问一下，你的那个VideoRecorderAndCompressor 项目里面的录制完的视频通过ffmepg进行再次压缩可以让assets-->armeabi-v7a--->ffmpeg文件现在是14M，直接导致发布的apk变的很大，请问有方法让ffmpe文件变小（能够满足本地视频压缩即可），或者有什么其他的方法让apk打包的时候仅仅大一点点（大1M内）最多，者FFmpeg可以满足吗？如果不行，顺便问一下有其他方法吗？

压缩用时有做过统计吗
