Tutorials: on-demand and live streaming

This question was posted in response to the following article: http://help.adobe.com/en_US/flashmediaserver/amazonec2/WS6fc2df2b6d2ce24359910e2812c396a83 eb-7ff8.2.html

I followed the instructions to "Live Streaming with DVR", but it's not quite working for me. I'm able to push a live stream to the EC2, and view it through the Flash Media Playback Setup page under the "Live" option in the Advanced tab. However, I am not able to enable the DVR functions. I have added the dvrcast_origin folder to /mnt/applications, as instructed, but I have no "streams" folder in dvrcast_origin, nor any video from the stream saved to the EC2 that I can find. Any suggestions?

Flv and live streaming

I am unable to play flv applications and live streaming on my nokia lumia 520, why?

Hi, Saqib213. The .flv video file format is not supported by the Lumia 520. For the list of supported file formats, please check this link: http://www.microsoft.com/en-gb/mobile/phone/lumia520/specifications/. Alternatively, you can check the Store for any applications that offers .flv playback functionality.
As for your live streaming concern, where are you trying to stream? Are you using an app or via a website? Is there any error message? You can only watch live streams through websites that supports the HTML5 & Silverlight, as these are the supported technologies for WP8 devices.

IPad And Live-Streaming

Does anybody know if iTunes will ever have live-streaming of movies for iPad to compete with VUDU and Netflix? Thank you in advance for any opinions!

Live stream - buffer and replay

Hi,
i have this issue, which i'm pretty sure isn't feasible, but my boss insists that i give it a try, so here we go:
i've developed a video player being used by a commercial TV channel, both for its VOD and live stream. all the video content - live & VOD - is supplied via external CDN, over which i have little (or even no) control.
what we're trying to achieve now, is while the channel's live stream goes on commercials break, to display our own (website's) ads. we can tell when the break begins and when it ends, but we cant' know in advance how long it'll last.
so our plan is to start running our own ads as the break begins, and when it ends - in case the ad is still running, buffer and 'record' the live stream, so when the ad ends the player will display the live stream, but from when its commercials break ended, with a short delay.
is such a thing even possible? i mean displaying live stream with a deliberate delay?
thanks in advance for any thought or idea,
eRez

Hi,
One way you can do this is to use php script to identify the user agent of the client (http://php.about.com/od/learnphp/p/http_user_agent.htm) and then generate dynamic webpages based on the client (HLS for iOS based clients and HDS for flash based clients). As Apache can only serve static webpages, you'll need to use CQ/MySQL/something else. I've personally not attempted to do so, but this may be a good starting point : http://www.ibm.com/developerworks/linux/tutorials/l-php/
Hope this helps.

Re-Start a Live Stream using AMS 5 through Cloudfront

We have AMS 5 running on an Amazon EC2 instance. We send a Live Stream from an FMLE encoder using H.264/AAC.
If we do an Origin Pull from that instance running the AMS 5 and Live steam through one of our commercial CDN accounts, we can stop and re-start our Live stream without issue. It stops and re-starts as it should. When we re-connect to the AMS using FMLE, using the Origin Pull, the stream re-starts in either the OSMF or JW Player 6 in under 30 seconds.
If we use that same AMS 5 on the same EC2 instance and Live stream through an Amazon Cloudfront distribution, if we stop our Live stream, when we re-start the stream it takes an unacceptably long time for the stream to refresh - if ever. Basically, after the re-start of the Live stream through FMLE, the Live stream at the player plays the first 10 or 15 seconds of the intial Live stream and then stops. If you refresh the player, it will play that same 10 or 15 seconds again - and stop again.
It would seem that the AMS 5 is setup correctly. It works through our commercial CDN.
It also would seem that the issue is with the cache on Amazon Cloudfront. Our assumption is that the Cloudfront cache is not properly updating. But we have tried about every variable in every setting for Cloudfront that we can find. We can't get past this.
Any suggestions?
Thanks

There appears to be 2 different issues - one issue with Amazon Cloudfront and a second issue with Adobe Media Server. Unfortunately, they are tied together in the real world application of these programs.
In AMS. when we use the adbe-record-mode=record, then the AMS works fine because the AMS is clearing the streams on each re-publish. Unfortunately, this causes a status code error on Amazon Cloudfront. And that particular status code error from a custom origin server causes Cloudfront to "override the minimum TTL settings for applicable cache settings". As the programmers explained, basically what happens is that Cloudfront overrides our 30 second cache settings and goes into a standard cache setting of 5 minutes. And waiting 5 minutes to re-start a Live stream just doesn't work in the real world for real customers.
We can fix that Cloudfront status code error issue by using adbe-record-mode=append on the AMS. If we use that AMS setting, then we can stop a Live stream, re-start the stream, the Cloudfront cache clears and everything works - unless you also change the stream settings in your FMLE. If you stop the stream and change the video input or output size in the FMLE, then the AMS server gets stuck and can't/won't append to the f4f record file.
Does anyone have any ideas about how we can adjust all of this so that it works together?
Thanks

Sending Live Stream from one FMS to another FMS

Hey,
Here's what I would like to do:
1. The Flash Media Encoder sends a live stream to FMS 1
2. On FMS 1, a connection to FMS 2 is set up and the live
stream is sent to FMS 2.
3. Every second, a message with metadata is sent to FMS 2
using Stream.send()
4. A Client connecting to FMS 2 receives the stream and the
metadata that was sent along with it.
I know this sounds pretty confusing, but the main problem is,
that I don't have access to the FMS 2, so I can't call
Stream.send() there. First I thought the solution would be using
Stream.play() with a remote connection, but when I call the
Stream.send() method nothing happens on the client side.
Then I thought I could do the whole thing by using a client
side application that connects to FMS 1, receives the stream,
embeds the metadata and publishes it to FMS 2. Here's the code I
used:
// Connect to FMS 1 to get stream
client_nc.connect("rtmp://localhost/encoder_stream/room_01",
"Client");
// Create input stream
in_ns = new NetStream(client_nc);
// Connect to FMS 2
akamai_nc.connect("rtmp://localhost/akamai/room_01",
"Client");
// Create new stream, feed with in_ns and send to FMS2
out_ns = new NetStream(akamai_nc);
out_ns.publish("stream");
out_ns.attachVideo(in_ns);
Unfortunately the attachVideo method only accepts a camera
and not a netstream object.
So this is where I'm standing now... anyone any ideas?
thanks

Hello,
i've asked our Akamai contact and they say it's not possible
to install any scripts on their servers. I think the only way is to
push the stream from FMS1 to FMS2, but since FMS doesn't support a
push method, there i have to find another way *sigh*
I've heard about FMS version 3 coming up soon, and I'd really
like to play around with the alpha version. Any idea where you can
get it from? On Steve Wolkoffs blog it says the new FMS is going to
support a push method:
http://blogs.adobe.com/dreaming/2006/10/fmsnext_feature_open_thread.html
I've also played around with the Red5 server, but I couldn't
find anything there to achieve a server side push method. Does
anyone have any experience with Red5 and live streaming?
Cheers!

Latencies / delay in live streams

I'm doing some tests with FMS and live streaming, but I observe quite long delays.
When the stream is first accessed, the latency is around 3-5 seconds, which is acceptable.
But as we watch the stream for about 30 minutes or more, the latency grows to around 20 seconds, which is just too much.
What settings should I look at to keep the latency / delay minimal?

You're going to want to look at the bandwidth that you're pushing into your FMS system and the bandwidth you're getting out. Usually when you see evolving live latency it's because there's a bandwidth bottleneck somewhere and you're dropping frames and falling behind as FMS attempts to deliver a stream that's too big for the destination. If not then perhaps it's something else, but you'll want to eliminate that possibility first as it's the most common.

Live stream HDS and HLS with one webpage.

Hello,
First off, I am not a web developer, but I can put together a page if I have to. I have been tasked with setting up our Adobe Media Server 5 for live streaming and have successfully gotten the HDS and HLS streams running. I have created the two pages on our webserver to link to the HDS and HLS streams and I wanted to be able to integrate them into one page so the users don't have to choose the appropriate stream. Can anyone point me to a site or maybe an adobe help on how to do this simply and effectively? Does adobe have some prewritten code for this somewhere?

How can I do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder which does not have firewire out/input? it comes only with a component video output, USB, HDMI and composite RCA output?

I need to do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder (http://store.sony.co...ber=HDRAX2000/H) ..this camcorder model does not have firewire out/input ..it comes only with a component video output, USB, HDMI and composite A/V video output..
I wonder how can I plug this camcorder to the firewire port of my laptop? Browsing on internet I found that Grass Valley Company produces this converter http://www.amazon.co...=A17MC6HOH9AVE6 ..but I am not sure -not even after checking the amazon reviews- if this device will send the video signal through firewire to my laptop, in order to live streaming properly? ..anyone in this forum could help me please?
Thanx

I can't broadcast with the built in iSight webcam... how would I zoom in or zoom out? or how would I pan? I've seem people doing it walking with their laptops but that's not an option for me... there's nothing wrong with my USB ports but that's neither an option to stream video because as far as I know through USB you can't connect video in apple operating systems ..you can for sure plug any video cam or photo camera through usb but as a drive to transfer data not as a live video camera... is by firewire an old interface developed by apple that you can connect all sorts of cameras to apple computers... unfortunately my new sony HDR-AX2000 camcorder doesn't have firewire output...
thanx

How to create Live and Archive Streaming URLs??

Hello Pros,
I am new to QT Streaming Server, and how it is setup and delivered. Please take it easy on me. Here are my questions.
Our school has been using Helix (Real) Server to deliver some video content via Live/Archive streaming video. The school will be changing a format to QuickTime Streaming server to move away from Real. We would like to deliver MPEG4 file via Live Streaming and archive. We set up QT Streaming Server and we can deliver video now.
How do you create and display URLs on a webpage to share live and archive movies? In RealServer, you can list URLs with live and archive, and RealPlayer opens separately and play movie. The videos are lectures so the website will have list of lecture links as we record every week.
If I click this link, a RealPlayer opens and start playing. Currently, I know that “sdp” file is assigned under RealPlayer. When I changed it to QuickTime Player, the player does not open to play movie. Is there way for me to setup URL to open it in external player? We are not interested in making the movie playable inside webpage. We would like to let viewers have option to stretch the movie player to view larger image if they wish. Strange thing is that when the live movie is played in RealPlayer, the image size is smaller that what we stream (320x240). How is it possible? I am confused…
How about archived streaming URLs? I have seen sites with embedded movie in the webpage, but how do you make links that when a viewer click the URL, it will start QuickTime Player externally instead of open it in new webpage? Is this possible? In RealServer, you can use “ramgen” code in a part of URL to open RealPlayer to play a movie.
Any help will be appreciated it.
Thank you.

Live streaming in lion 10.7.2 and safari 5.1.1

yh, ok so i have lion 10.7.2, the latest of safari and a very good internet connection, my live streaming is not that encouraging, there must be a plug-in or something to enhance it ryt? can anyone share an advice on that please? thanks

So far the only solution I have been able to find has been launching the recovery partition and running disk repair. That will fix the problem until you trigger it again. Fortunately, or unfortunately, I have pinpointed what triggers it on my computer.
Seems to be a flaw in keychain access. When Safari's connection times out due to an expired certificate (common in university networks that require a log in every few hours), the security settings freak out and effectively shut down safari's ability to do anything. The fact that it attacks KeyChain access and iPhoto and more is just a really big system wide glitch. Here's the run down:

Found out last night that i couldnt watch a live stream confetence because i couldnt download the flash player. why does apple not allow to do that and is there an alternative way other than flash player?

found out i couldnt watch a live stream coference because apple wont allow to download adobie flash player. why is this and is there a way around it to be able to catch more of live stream in future.?

In the future, there won't be any Flash. Adobe, who makes it, has cancelled future versions for mobile devices like the iPad:
http://www.wired.com/gadgetlab/2011/11/adobe-kills-mobile-flash/
You should check if there is another way to get the live stream. For example, I sometimes watch online classes on a site that uses Flash for the video. But they also provide a non-Flash video stream that can be watched in an iPhone or iPad web browser, and an iOS app that you can also use to watch the stream.

Adobe FMS 4.5 and Streaming to DVR and Live Not Working

Hello,
I am having some issues with streaming Live and DVR. I am fairly new to the FMS world, but not to the streaming media world.
I am using a FMS server on AWS, version 4.5. I have installed DVRcast on the server and created a test application. I am seeing no errors in the logs, all services are running properly. No errors when connecting to the serve via FMLE. Logged into the Admin Console, I see the connection. In the Adobe Flash Media Playback Setup player, it just buffers. I try to play the rtmp stream in another test player and get a security error. Any suggestions would be greatly appreciated.

Also having the same problem.
Have installed the applications and stream to the server using FMLE with the DVR Auto Record on and the server is receiving the stream.
But there is no file being saved and when I try to connect with a RTMP player it failes to connect, the livedvr_client_test sample code gives back "Main.as : Not connected to FMS yet - Trying again ...."
Normal LIVE streaming works, it is just the application. Followed the PDF to the letter.
Any help with this would be great!
Thank you.

Time shifting and record live stream

Hellow everyone,
I would like to stream videos for my viewers and them have a abiliti to timeshifting live stream.
Can I use live application for timeshifting? Or I should use livepkgr to do that.
For archive and play on the VOD mode I like to stream live and record at same time. in the livepkgr I see in the stream folder create a stream file with the f4f extention automaticaly whoever in the live application I should call application.record on the FMS to save live stream on the server.
Please advise me the better solution to archive and time shifting.
Many Thanks.

livepkgr application for for HTTP streaming...
f youjust want to stream over rtmp use live application and code to record the stream...recording is pretty simple in AMS just call Stream.get() s.record(...) s.play() where s is the stream which you are recording...
application.onPublish = function(clientObj, streamObj) { trace("recording started..."); var strName = "recorded_" + streamObj.name; var s = Stream.get(strName); if (s == undefined ) return; s.onStatus = function(info) { trace(info.code); } if (!s.record("record")) { s.trace("record failed."); } s.play(streamObj.name, -1, -1, true); }
