I'm streaming live video from Flash Media Server via RTMP. Is there any way to get a list of all available streams?
I already know the names of a few streams, but I'm wondering if there might be others, is there a way to find them?

I am using native Safari player implementation to stream video with HLS streaming protocol.
My goal is to get time-based metadata (such as EXT-X-DATERANGE) from a live stream manifest.
As far as I know, it is not possible to retrieve this data because the streaming logic is fully controlled by the Safari player which does not expose this data.
For now, I came to the 2 possible solutions:
Manually download the manifests and parse out the EXT-X-DATERANGE tag. But with this approach, the download timer should be manually managed too. And, of course, the number of requests for the playlists will be increased.
Desktop Safari browser supports MSE. This means it is possible to have full control over manifest retrieving and parsing. There are awesome libraries that already provide this functionality, such as shaka-player or hls.js. It is possible to implement custom response filter for segments(shaka-player) or listen to Hls.Events.FRAG_CHANGED event (hls.js) in order to have access to the playlist. The problem is that Safari in IOS mobile still does not support the MSE. So it is not possible to apply this solution for mobiles.
Are there any other ways to retrieve time-based metadata (such as EXT-X-DATERANGE) using native Safari player implementation?
Thanks a lot in advance!
In Windows Phone 8.1, I want to play an internet radio station with Windows.Media.Playback.MediaPlayer. I'm aware of a sample which plays mp3 files with MediaPlayer.SetUriSource. However, I don't know how to play a stream. I see MediaPlayer.SetStreamSource, but it appears to be for random access streams which support seek, etc. I'm not sure it's for live streams.
Which method should I use?
Any tutorials or docs on this? I couldn't find any.
You could have a look at the Windows Phone Streaming Media library, which supports live streaming and HLS formats.

What is required to use SMIL file to utilize adaptive streaming in a videojs player. I have created the SMIL file in my wowza application and it is creating my 4 separate streams and making them available. However I cannot get my webpage, that uses videojs, to correctly play the SMIL file. Hints on that coding or where to go to find the correct documentation would be greatly appreciated.
There aren't many implementations of SMIL players. I'm sure I've seen wowza URLs that suggest it will output the SMIL as other formats, something like whatever.smil/manifest.m3u8. That's HLS which could be played on mobile and Safari natively and with videojs-contrib-hls elsewhere.
I know the question is old, but I've been struggling with this recently, so I want to share my experience in case anyone is interested. My scenario is very similar: want to deliver adaptive bitrate streaming from Wowza to clients using videojs.
There is a master link that explains how to setup and run Wowza Transcoder for live streaming, and how to set up your Adaptive Bitrate Streams using an SMIL file. Following the video in there you can achieve to have a stream that uses ABS, but the SMIL file is attached to the stream name, so it is not a solution if you have streams that come to Wowza from another Media Server origin and that need to be transcoded before being served to the clients. In the article there are a few key things mentioned (like the Stream Name Groups), but somehow things doesn't seem pretty clear, at least to me. So here is some clarification from what I understood from all articles I read and what I did to achieve ABS:
You can achieve ABS in Wowza either with SMIL files or with Stream Name Groups (NGRP). NGRP refres to a block of streams that is defined in the Transcoder template that can be played back using multi-bitrate streaming (dynamically) (<- this is what I used). And SMIL files are used to create a "static" list of streams for multi-bitrate VOD streaming. If you are using Wowza Origin-Edge Delivery you'll need the .smil file, because NGRP do not get forwarded to the edge. (Source for all this information: here).
In case you need the SMIL file, you probably need to generate a new one for every stream, and probably you want to do that in an automated way, so best way would be through an HTTP request (in the link above it is explained how to achieve this).
In case you can live with NGRP, things are a bit easier:
You need to enable Wowza Transcoder (this is pretty easy and steps are in the video I mention above).
You should create your own Transcoder Template with the different stream presets you want to deliver, as an example you can check the default ones that are already there. The more presets you add, the more work Wowza will need to do whenever a stream comes, since it will need to generate a new stream for every preset that you have defined.
Now is when we generate the NGRPs. In your Transcoder Template, you can generate as many NGRPs as you want (to clarify: these are like groups of streams, that you will be able to set in your clients video player. Each NGRP contains the streams that the video will be able to use when doing the adaptive bitrate streaming). For instance, these are the default NGRPs:
If you play the ngrp "_mobile" in the clients video player, the ABS algorithm in the player will be able to adapt itself to play either the 240p or the 160p streams based on the client capabilities.
So imagine you have these two NGRP. In order to play them in videoJS, you will need to set the source to:
http://[wowza-ip-address]:1935/<name-of-your-application>/ngrp:myStream_all/playlist.m3u8
or
http://[wowza-ip-address]:1935/<name-of-your-application>/ngrp:myStream_mobile/playlist.m3u8
... based on how many options you want to provide to the client player to use for the ABS. (For instance: if your targets are old mobile devices, you probably just want to offer a couple of low bitrate streams).
(This would be in case you're delivering an HLS stream. If other format, the extension would change, for instance if you are delivering a DASH stream you would have "/manifest.mpd" instead of "playlist.m3u8").
That is all, there is also a very helpful link in video.js documentation explaining how it does the bitrate switching: here.
I hope it helps someone! At least clarifying things! :)
Trying to roll out a video to a client with limited bandwidth. The client is concerned that the video will eat up all the bandwidth at their field office. In testing, I've discovered that even though my video is encoded at 420kbps, when downloading the client it still utilizes about 1.5mbps. Is there a way to control the maximum bandwidth used by video.js or the video tag?
Unfortunately no. The html5 video element doesn't have any throttling options. It's completely up to the browser to decide how to fetch the video data. Some will download the whole thing at once, others will download pieces as you need them. All I think will use as much of the pipe as you give them.
The media source extensions proposal hopes to add some ability here, but that won't be available for a while.
I would find somewhere else besides the office to host the video, like Amazon S3.
I was doing some research to find out ways that would allow me to stream music on my website legally. I came across iTunes partner program which allows to stream music on a website through their embedded players. I was wondering is it possible to stream iTunes music through your own custom player? If that is not possible via iTunes, then what other methods are available?
You could do this with a server software like Icecast, there is some good tutorials on setting this up here: http://www.icecast.org/docs.php
Depending on how many browsers you want to support you might want to setup two streams, one in MP3/OGG and a "backup" stream in Flash. Then add some detection as to what the browser supports and present the correct stream (i.e.: Use the HTML5 <audio> tag for playing MP3/OGG to browsers that support this, and use your flash stream for the rest)
their program allowing playback of music in the iTunes Store is likely only for those with the intention to sell music, without providing a commerce business, you'd be breaking their partner program T&C's.
