Log.i("message", outDirPath);
String[] splitCmd = exec.split(" ");
Log.i("message", Arrays.toString(splitCmd));
//String[] command = {"-i", mediaPath, "output.mov"};
FFmpeg.getInstance(this).execute(splitCmd, new ExecuteBinaryResponseHandler() {
//execution
}
答案1
使用：
-var_stream_map 'v:0,a:0 v:1,a:1'
- 变体流组之间以空格分隔。
- 每个组内的流以逗号分隔。
- 引用该字符串以防止不正确的解析。
