FFmpeg错误输出文件#0不包含任何流

Question

我在使用FFmpeg剪切部分视频时遇到错误

以下是我的代码

String[] cmd = {"ffmpeg -ss 0 -i "+mPath+" -t 30 -c copy "+ (Environment.getExternalStorageDirectory().getAbsolutePath()+"/sample.mp4")};
executeCommand(cmd);

函数executeCommand

void executeCommand(String[] cmd) {
    try {
        fFmpeg.execute(cmd, new FFmpegExecuteResponseHandler() {
            @Override
            public void onSuccess(String message) {
                Toast.makeText(VideoFullScreen.this, "finished :" + message, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onProgress(String message) {

            }

            @Override
            public void onFailure(String message) {
                Log.e("Error",message);
            }

            @Override
            public void onStart() {

            }

            @Override
            public void onFinish() {

            }
        });
    } catch (FFmpegCommandAlreadyRunningException e) {
        e.printStackTrace();
    }
}

Answer 1

这是我自己的问题的答案

我的问题出在我传递的命令字符串数组中

这个答案是针对所有人都面临类似问题的人 ffmpeg

使用时应遵循的重要事项 ffmpeg

1. 确保您正在传递命令 String Array

   String[] cmd = {"-ss", "0", "-i" ,input_video_path, "-t" ,"30", "-c", "copy",output_video_path};
   

2. 不要extra space在你传递的参数和标志中添加任何{ " -c"错误}

3. 不要传入ffmpegcmd数组{ "ffmpeg" is错误}

希望这会对某人有所帮助
