If your streams contain just one media type - i.e., just video or just audio - then you could write an ‘elementary stream’ file instead.

E.g., if your stream is H.264 video, you could feed the received video data into a “H264VideoFileSink”, and you will then get a file that could be played (or re-streamed) while it’s being recorded.
