Hello,

I have two questions regarding video streaming from server to iOS device.

1. Now I have HTTP LS (Live Streaming) stream and I want to use OpenTok instead. Question is what requirements are for OpenTok server side part to stream video? (What kind of media source can it use?) Where can I find some docs on setting up streaming from server to device? (I have already read this: http://www.tokbox.com/opentok/api/tools ... aries.html but there is no information on how to pass media content to server side tools)

2. The second task is to have 3 audio streams and one video in one session and to have a possibility to switch between audio streams on device. Is it possible?

Thanks in advance and sorry if this questions were already answered elsewhere, I would appreciate any links.

OpenTok media sources must originate from instances of the OpenTok SDK; if you have your own HLS source, you'll need to use a different mechanism to deliver it to your clients. We have looked at the possibility of server-side media sources, but nothing has been specified and it's unclear whether we'll pursue that feature.

You can subscribe to multiple OpenTok video streams using the SDK. Again, the streams must be sourced by other OpenTok instances in order for this to work.

Thank you for answering, I'm new to OpenTok so not everything in your answer is clear for me.

Now I have HLS stream received on device, thats correct. I know that OpenTok is not suitable to receive it, and thats why I plan to setup server-side part of OpenTok libraries and completely remove HLS. When talking about server requirements I meant requirements to media content (codecs, frame/bit rates and so on) that will be used by OpenTok.

As for multiple audio streams as I understood this is not possible and the only option is to setup three streams with the same video and different audio?

I'm afraid I do not understand the scenario you are describing. The only way to get media onto an OpenTok session (both audio and video) is from the OpenTok client's camera & microphone. Multiple audio streams on a session is possible, however the audio streams must all be microphones from different devices/browsers. You cannot currently source audio or video from a server component of your own writing.

You're right, my idea was to stream video from server to iOS device getting video from source like media file or other not OpenTok based stream. In fact this video will come from a TV studio to the server and, as I understood, there is no option to use OpentTok for this segment of transmission.
Do you plan to implement such a functionality someday?

Anyway thanks a lot for your answers, this was not obvious from documentation.

Some day, yes, or at least I hope so. We haven't yet figured out how it would look as a public-facing service, and there is no prioritization against the product roadmap at this time. If you would like to discuss with our business development staff about the application you're thinking about building, the feedback is always useful for us to understand what the future might look like for the product: contact@tokbox.com

This is simple videos steaming concept.But any you tube app which play without steaming(buffering)?

This is a video chat API. I don't think we're what you're looking for.
