This is done so that host can detect end of transfer and pass data for processing. Still, frames that are multiple of 16K in size gets dropped. The ZLP sent by camera is ignored by uvc_video_decode_bulk(). The makes sure that the ZLP is not part of a video frame before ignoring it. If ZLP follows a video frame, then it triggers completion callback.
