[PATCHv1 05/12] vivid: add the video capture and output parts

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Hans Verkuil <hans.verkuil@xxxxxxxxx>

This adds the ioctl and vb2 queue support for video capture and output.
Part of this is common to both, so that is placed in a vid-common source.
