Subject: v4l2-dbg: autodetect stride Author: Hans Verkuil <[email protected]> Date: Thu Mar 17 12:02:20 2016 +0100 When listing registers v4l2-dbg now queries the first register to detect the range that should be used. If non-zero that size is used, otherwise the given stride value is used. Support for formatting for a stride of 2 is also added, that was missing.
