a57e3f365a video.c: modify set_buf call seqence in start_capture function. 
To avoid losing the first frame, the set_buf needs to excute first. At the same time, imgdata->start_capture should excuted before the imgsensor->start_capture.

Add initialization of flags member to avoid return of the garbage value.
