Bug Report: The function load.video doesn't work

[JiaxiangBU]

When I run this code to extract the infomation for this sample video.

imager::load.video(system.file('extdata/tennis_sif.mpeg',package='imager'))

I get this error

Error in tryCatchList(expr, classes, parentenv, handlers) : No output was generated

I follow wiki to install the FFmpeg and check this issue #75 to make sure the FFmpeg is successfully installed and set.

Can you please report which version of imager you're using, and on which platform? Run packageVersion("imager")
