 Worker.run() is similar to FFmpeg cli tool, aims to provide maximum flexiblity for users.
 
 **Arguments:**
 
 - `args` a string to represent arguments, note: inputPath must start with `/data/` as worker.write write to this path by default.
-- `options` a object to define the value for input, output and del.
-  - `input` a string or an array of strings to indicate input files, ffmpeg.js deletes these files for you.
-  - `output` a string or an array of strings to indicate output files, ffmpeg.js moves these files to `/data`, deletes them from MEMFS and you can read them with Worker.read()
-  - `del` a boolean to determine whether to delete input file after the task is done, default: true
 - `jobId` check Worker.load()
 
 **Examples:**
 
 ```javascript
 (async () => {
-  await worker.run("-i /data/flame.avi -s 1920x1080 output.mp4", {
-    input: "flame.avi",
-    output: "output.mp4"
-  });
+  await worker.run("-i /data/flame.avi -s 1920x1080 output.mp4");
 })();
