Overview:

Yes you can use the tmp package where you can store the video into a specific file pass it to ffmpeg and then clean the file after all processing is completed

Note: I recommend using the tmp-promise since it make it easy to deal with promises

1. Import the package

const tmp = require("tmp-promise");

2. Set the temp dir

  // Temp directory const tempDir = await tmp.dir({   unsafeCleanup: true, });

3. Save the file into the system using the tempDir path

   // Get The video file     const video = req.file;    await fs.promises.writeFile(      `${tempDir.path}/${video.originalname}`,      video.buffer    );

4. Process the video

here you can pass the file to the ffmpeg and process the video as you like with your specific need

note: file name is ${tempDir.path}/${video.originalname}

5. Clean up the directory

 tempDir.cleanup()
