[optional] upload the media file that is in question.

ffmpeg version: 1.0.11

question:

In my app, we want to grab video stream from a usb camera, but did not get a api or a way to open the usb camear.

my codes as follow:
string videoName = "0";
MediaReader reader = new MediaReader(videoName, null, null));

it throws a exception: FFmpeg error [-2] No such file or directory

It is best to check the documentation for the use of ffmpeg.
