Silence Error Messages

Not a bug report, but a request for a bit of help...

Is there a way to disable to disable (error) messages from underlying programmes?

I'm doing the following to check whether a video is corrupt, millions of times:

```
try:
vr = VideoReader(path)
# video is fine...?
except Exception:
# video is not fine...?
```

But the error messages, such as `ffmpeg`'s `moov atom not found` is obstructing my output. Is there any way to disable them?
