[RFCv2,04/14] vpif_display: move output_id to channel_obj.

Commit Message

Hans Verkuil Sept. 20, 2012, 12:06 p.m. UTC

From: Hans Verkuil <[e-mail]>

The output index does not belong to video_obj, it belongs to
channel_obj. Also rename to output_idx to be consistent with
the input_idx name used in vpif_capture.
