#15 Switch to disable/enable video playback while transcoding

[Tourneur Henry-Nicolas]

Hi,

It would be great to add a switch to enable or disable video playback during the encoding process.

As it may takes times, the user probably won't look all the time to the playback.

Furthermore, on some computer with bad video driver (think of nvidia & nv driver), the video playback may eat a lot of cpu usage...

Regards,
