Doesn't Wowza mostly do offline content, e.g. pre-recorded video?  Even in the case of live streaming, the keyframeless option is really only useful if you're trying to go for very low latency, which as I mentioned in the blog post isn't very useful for ordinary broadcast purposes.<p>The primary target of all this is <i>interactive</i> video: gaming, videoconferencing, and maybe something like Livestream or Justin.tv where a person interacts with viewers who are chatting with them.  Ordinary broadcast probably won't benefit.<p>I should note that the keyframeless solution is <i>not unique</i> to our system: this was done a few times in MPEG-2 broadcast encoders back in the day, as well as in some mezzanine stuff.  I haven't seen anyone do it in H.264 though yet; it is made slightly more tricky due to the way that intra prediction in H.264 works.<p><i>What are the implications for automatic bandwidth adaptation?</i><p>We don't support that yet--but that will probably come soon, as it's the natural next step forward.  (Currently the encoder's ratecontrol settings can't be changed without re-initting it.)
