Questions & Answers
Q: Does the player decides which bitrate is used?
A: Yes, the client chooses which bitrate to use out of the ones which are available in the .smil file. It works by detecting a user's bandwidth and CPU capacity in real time and adjusting the quality of a video stream accordingly. The player client switches between streaming the different encodings depending on available resources. The result: very little buffering, fast start time and a good experience for both high-end and low-end connections. Find out how to setup ABR here: http://www.wowza.com/forums/content.php?546
Q: Is there any tweaking that is needed to be done for a rtmp stream be played by jwplayer and seen in a windows phone, android phone, iphone, ipad AND windows AND linux AND MacOS, or we can be sure that it works no matter what?
A: You can set up multiple sources using RTMP as a primary with a fallback HLS stream for HTML5 devices, but JW Player Premium can handle HLS on desktops with Flash just fine.
Q: Is WOWZA capable of capturing live signals say off satellite to then be delivered into the JW Player?
A: Yes, this workflow is supported and has been implemented by many users.
Q: So, is this correct??? If you purchase wirecast pro for a computer you are already using, and subscribe to the churchstreaming.tv package, will you then have everything you need to do everything you demonstrated today?
A: That is correct. We offer a 30 day full functionality trial, check it out yourself.

A: If the encoding inputs are H.264 and audio AAC
Q: We are hosting our JWPlayer locally, does this reduce the functionality?
A: If this is self-hosting rather than cloud-hosting, no. This shouldn't affect functionality.

Q: Configuring secure token and jwplayer6
Q: Server sizing for running Wowza?
A: We recommend a dedicated quad core server with newer model Xeon chips, 8 - 16 GB of RAM, and at least a 1 GB ethernet network interface connector (NIC). On the software side, you will need to deploy a 64-bit operating system & a 64-bit Java VM.
Q: Which protocol gives best quality, RTMP or HLS?
A: HLS vs. RTMP quality is very similar. The difference is that RTMP requires flash, and delivers with significantly less latency to live. HLS supports iOS and other mobile devices.
Q: Can Wirecast be set to automatically reduce bandwidth or automatically restart stream if the internet has a temporary problem?
A: Yes, the UI has that information across the top of the application. You will first see Green go to Orange if you're losing bandwidth and to Red if you're offline. WC will continue to try to reconnect.
Q: What does HLS stand for, what is it?
A: HTTP Live Streaming
Q: Very interested in how you guys capture live signals from a broadcaster to then deliver to the JW Player.
A: You can request this broadcast video white paper: http://info.wowza.com/broadcast-white-paper
Q: JWPlayer knows when to use HSL or DASH (doing device detection) or we have to do that and tell JWPlayer when to use one or another?
A: Dash is still not yet implemented for JW Player, but there will likely be HLS fallback if your browser/device does not support dash.
Q: Will there be any mention of linear/live streaming of television?
