It depends. How critical is the content you are streaming? If critical use TCP. This may cause issues in bandwidth, video quality (you might have to use a lower quality to deal with latency), and latency. But if you need the content to guaranteed get there, use it.

Otherwise UDP should be fine if the stream is not critical and would be preferred because UDP tends to have less overhead.
