Once the hfi_session_flush is issued by the vdec all queued buffers to firmware should be returned to the v4l driver. Some of those buffers are not processed at the time of flush command, those buffers has filled len zero (no data). Catch that in buffer_done callback and mark not filled capture buffers with error state so that client can discard them.
