All talks will be live streamed, and right after the talk is done you have a rough cut available instantly under "re-live" you can watch until the final recording is available; https://streaming.media.ccc.de/39c3/relive
I should note that some talks will not be recorded, and only available at the congress. These are clearly marked on the congress hub website, but not easily available on the fahrplan view.
