Error getting frames

Hi,
I have an issue with a video that plays fine, but when i try to get some frames it rises the following error:
`decord._ffi.base.DECORDError: [10:27:30] C:\projects\decord-distro\decord\src\video\video_reader.cc:641: Error getting frame at: 0 with total frames: 199`

I'm using decord version 0.4.2 installed from pypi, python 3.6.6 on Windows 10. I can't upload the video for confidenciality reasons, but this is ffprobe diagnose info:
```
Input #0, avi, from 'C:\file.avi':
Metadata:
software : MEncoder SVN-r33883(20110719-gcc4.5.2)

```

I'm using `VideoReader.get_batch()` function when i get this error. Also, when i use `VideoReader.next()` function it returns `None`. And when i use `VideoReader.seek(0)` function i get: `RuntimeError: Failed to seek to frame 0` and the same for `VideoReader.seek_accurate()`. When i open the video file with `VideReader.open()` function, i get a warning message: `[11:52:27] C:\projects\decord-distro\decord\src\video\video_reader.cc:277: Failed to seek file to position: 0`

I think is a similar problem to #83 issue, but i'm not getting the same error messages. How could i solve this?

Thanks in advance.

EDIT:
It seems to be the same problem as #100, however i dont understand how to solve it.
