Getting Error: write EPIPE

[tention]

Describe the bug
Trying to generate the thumbnail using a buffer, so what i did was:

1. Adding faststart so it works on mov and mp4 file
2. Convert it to Readable before parsing to genThumbnail
3. The thumbnail was generated at /tmp/test.jpg, however i'm getting following error that terminated my nodejs application.

            })
              .then(() => console.log('done!'))
              .catch(err => console.error(err));
