Subject: [media] vivi: fix sequence counting Author: Hans Verkuil <[email protected]> Date: Mon Feb 10 08:08:45 2014 -0300 The sequence counting was not reset to 0 between each streaming run, and it was increased only every other frame. This is incorrect behavior: the confusion is with FIELD_ALTERNATE systems where each field is transmitted separately and only when both fields have been received is the frame sequence number increased.
