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.

Add an Intro FLV before live stream starts

Hi,
I have a console that has a main VideoDisplay that will
broadcast a live stream.
I'm using FME 2.5 with FMS 3.02.
What I would like to have the ability to run a looping FLV in
the VideoDisplay until the Live stream begins which will then cut
in.
I know this may be a FMS 3.02 config, but any advise would be
appreciated...
If it is also possible to play an Exit FLV when the live
stream stops..that would be a bonus....
Cheers

Hi Macnimation,
The tutorial is helpful only if you are using some Flash Authoring tools to write your playback client (which is playing back the video from the FMS at your side). In that case, inside your client code, there must be a NetStream object ns, and a statement like ns.play(filename, 0, -1), where filename is the name of your final video which you have created by combining the various videos you want to play.
So to create a playlist (as described in the tutorial), you need to modify the ns.play() statement. If your video files are named A.flv, B.flv, and so on, while the short intro video is named X.flv, you can write the following sequence of statements to create a playlist:
ns.play("X", 0, -1, true);
ns.play("A", 0, -1, false);
ns.play("X", 0, -1, false);
ns.play("B", 0, -1, false);
The last parameter (true/false) is the reset parameter. For the first time, it is true, to indicate that reset the play and start playing stream X immediately. For the following statements, it is false, indicating that play the stream A after the previous stream (i.e. x) is completed.
Thanks.

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?

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.
Thanks,

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.

Archiving live stream at FMS and injecting metadata: VP6 good h264 not

When I record a live stream at FMS, one in which I've injected metadata in my main.asc file, the archived file plays back fine. The metadata plays back too. I'm able to retreive it just fine - if I encode VP6.
If I encode h.264 the file plays back but the metadata does not. The fact that the archived file is created and plays back tells me things are wired correctly. The only thing I changed is the format.
According to FMS docs (http://help.adobe.com/en_US/FlashMediaServer/3.5_SS_ASD/WS5b3ccc516d4fbf351e63e3d11a11afc9 5e-7e42.html#WS5b3ccc516d4fbf351e63e3d11a11afc95e-7f35)
..."The recording format is determined by the filename you pass to the Stream.get()
method."
So my record code looks like the following:
application.onPublish = function(client, stream) {
     trace("onPublish");
     s = Stream.get("mp4:streamname.f4v");
     if(s){
         s.record();
     this.doRepublish(this.nc, stream);
My code that injects the data in to the stream looks like this:
Client.prototype.sendDataEvent = function(data) {
     trace("Call to sendDataEvent...");
     this.newStream = Stream.get("mp4:streamname.f4v");
     this.newStream.send("onTextData",data);
All must be wired correctly because the metadata comes through during the live stream. On play back of the archive though, the metadata doesn't appear to be there.
Any thoughts?
Thanks

My apologies on the s.play() confusion. I had been trying different versions of the code and posted the one without it.
Whether I include s.play() or not the file gets created. Here are the various versions of the onPublish() function I've tried (differences in red):
1.
application.onPublish = function(client, stream) {
    trace("onPublish");
    s = Stream.get("mp4:streamname.f4v");
    if(s){
        s.record();
        s.play("mp4:streamname.f4v");
    this.doRepublish(this.nc, stream);
2.
application.onPublish = function(client, stream) {
    trace("onPublish");
    s = Stream.get("mp4:streamname.f4v");
    if(s){
        s.record();
        s.play(stream);
    this.doRepublish(this.nc, stream);
3.
application.onPublish = function(client, stream) {
     trace("onPublish");
     s = Stream.get("mp4:streamname.f4v");
     if(s){
         s.record();
     this.doRepublish(this.nc, stream);
All produce the same result - an archived file called mp4:streamname.f4v in my streams folder. This file plays back fine but does not play back the commands.
On your other question, about things working fine for VP6, it works fine for FLV. A file called streamname.flv is produced. This file plays back fine and does indeed play back commands baked into the file as well. This is what makes me believe the code is not the problem. If it works perfectly for one format, there would seem to be very little I could do in my code to break things for the other.
Can you try this using the record() code snippets in the live docs Stream.record() section?
http://help.adobe.com/en_US/FlashMediaServer/3.5_SS_ASD/WS5b3ccc516d4fbf351e63e3d11a11afc9 5e-7e42.html#WS5b3ccc516d4fbf351e63e3d11a11afc95e-7f35
All you'd need is the code snippets there to record your live stream and another server side function to inject commands into that live stream. Here is that function:
Client.prototype.sendDataEvent = function(data) {
    trace("Call to sendDataEvent...");
    this.newStream = Stream.get("mp4:streamname.f4v");
    this.newStream.send("onTextData",data);
Do something simple like call onTextData and pass some text in the data parameter. Then on the client side viewer, handle the onTextData method. It will receive the text. Display it in a text area or something.
If you record while injecting this text into your stream, the text should display on playback of the archived file. It will if you encode VP6/FLV, but not if you encode H.264/F4V.
Let me know what you discover.

Live stream and codecs

Hello.
Here is described how to use different codecs for different
clients (Sorenson Spark for Flash Player 7- and On2 VP6 for Flash
Player 8+).
http://livedocs.adobe.com/fms/2/docs/00000081.html
But as I can see, it is only suitable for recorded .flv
files.
Is there any possibilities to customize stream delivery or
live streams?
Can FMS2 transcode streams on the fly?
Thank you.

FMS can't transcode or do any sort of recompression. It's
bits in, bits out.
If you publish through the Flashplayer, you will alwaus have
sorenson spark encoded video (the flashplayer only has the decoder
half of the VP6 codec). If you want to publish live VP6 video, look
into the Adobe Flash Video Encoder, or On2 Flix Live.

Playback of low bitrate flv or f4v from live stream in FMS causes player buffer to empty

We are experiencing a consistent issue when playing a low bitrate (300kbps or less) flv in a live stream from FMS. Basically, the player will will start off with the appropriate buffer, say 5 seconds, then begin dropping until it empties out, and will have to rebuffer. We've tried with a variety of flv and f4v files, all that are 300kbps or less, and we consistently get the issue. Is this something Adobe can investigate in FMS? Or are there any suggestions on how we can get around the issue?

Loop a short flv before the live stream begins

Hi,
Using FMS 3.02 and FME 2.5 is it possible to run a looping
flv that the clients can see, before the live stream begins, and
when the live stream finishes, an exit flv video plays?
cheers

Besides, can I draw data from DataBase (say, MS SQL Server) on server side? Can server-side ActionScript do this?

Configure Live streaming FLV Encodering -- Adobe -- End user

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.
