Android FFMpeg没有此类文件或目录错误 [英] Android FFMpeg No such file or directory error

问题描述

我正在将ffmpeg用于Android(使用gradle插件'com.writingminds:FFmpegAndroid:0.3.2')，并且尝试将视频裁剪为16:9(w:h)的比例.原始视频为1080:1920(w:h).当我执行命令时，我得到一个IOException No no file/directory.

I am using ffmpeg for android (using the gradle plugin 'com.writingminds:FFmpegAndroid:0.3.2') and I am trying to crop a video to a 16:9 (w:h) ratio. The original video is 1080:1920 (w:h). When I execute the command I get an IOException No such file or directory.

我正在使用的命令:

-i /storage/emulated/0/Movies/MyApp/result_joined.mp4 -vf crop=1080:607   -preset ultrafast /storage/emulated/0/Movies/MyApp/result_cropped.mp4

例外:

java.io.IOException: Error running exec(). Command: 
[/data/user/0/my.package.name/files/ffmpeg, -i, /storage/emulated/0/Movies/MyApp/result_joined.mp4, -vf, crop=1080:607, -preset, ultrafast, /storage/emulated/0/Movies/MyApp/result_cropped.mp4] Working Directory: null Environment: null
Caused by: java.io.IOException: No such file or directory

在没有帮助的情况下搜索了几个堆栈溢出问题.我还尝试将文件保存到内部存储而不是外部存储.结果相同

After searching several stack overflow questions with no help. I also tried to save files to internal storage instead of external storage. Same result

有帮助吗?

推荐答案

创建 FFmpeg 的实例后，您需要调用 loadBinary 方法.

You need to call loadBinary method after creating instance of FFmpeg.

try {
    ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
        @Override
        public void onFailure() {
          Logger.i(TAG, "ffmpeg not supported");
        }
    });
} catch (FFmpegNotSupportedException e) {
    e.printStackTrace();
}
