Recommended setup for live streaming of HD video and HE-AAC audio (5.1 channels)

Hi,
Could anybody please post a working hardware configuration for streaming HD video (720p) and 5.1 channel audio using HE-AAC via FMLE3?
What is your experience and what kind of professional equipment would you recommend (camera, capture card, type of cables used, PC specs incl. CPU and memory, etc.)?
I'm looking for a portable solution that ideally supports two concurrent streams (at different bit-rates) and multi-pass encoding (yes, I know that professional hardware supports that even for a live setting with a little delay).
FMLE (or is it Windows?) seems to be very picky as far as the recognition of HD data from specific input sources is concerned. Hence my question before investing into new hardware.
Thanks you.

Flash Player does not support 5.1 audio at this time, only 2 channel audio.
For what you describe, you may want to consider one of the streaming appliances or solutions from companies like ViewCast, Digital Rapids, or Inlet. ViewCast and Digital Rapids both offer portable appliances.
Flash Media Live Encoder does not support two-pass encoding, the only solution that I'm aware of that does this for Flash is Kulabyte that offers a 2-pass software solution as well as a complete solution with hardware.
If you use a capture card with FMLE you'll be fine with HD inputs, the problem seems to be with cameras that only offer HD source as MPEG-2 and FMLE only supports RAW input at this time.

Help with setup for live streaming

I'm trying to set up a live stream that's viewable on my
website.
I have two machines behind a router with one being the
webserver running FMS (windows 2003) and the other being the
encoding machine running FME (windows XP).
When I set up FME, I put in the following as the url to the
server "rtmp://
computernamewebserver/live/" with the session name being
"test".
This has no problems connecting to FMS .
On the webserver/FMS, I created a *.swf file which basically
contains just a flvplayback object with the URL set to "rtmp://
computernamewebserver/live/test".
Now after I publish this, I can view the video via the
published html file from within the network, but when I try outside
of the network, it doesn't work and I get no error messages so it's
hard to debug.
I have port 80 forwarded to my webserver/FMS machine. I tried
forwarding port 1935 to both my webserver/FMS machine and the FME
machine with no success.
I've tried playing around with the rtmp URL by changing the
computernamewebserver from the internally recognized
computer name to the externally recognized URL to my webserver.
The solution is probably something simple, but since this is
my first attempt at flash streaming, it's not obvious to me and
I've tried searching for the solution. My suspicion is that there's
some config file somewhere that I need to config that I don't know
about or maybe it's some port issue. Neither of my machines have
windows based firewall disabled.

"Now after I publish this, I can view the video..." Well this
shows that FMS is working fine, so I am guessing that it is an
outside network issue.
"Neither of my machines have windows based firewall disabled.
" I don't know if this is the cause either, as a host based
firewall should prevent any connections from arriving, either by
the internal lan or the external (well, at least I think that is
the case, I dont know if windows still allows hosts on the same
subnet to have local lan permissions or what they do with their
crazy security model. That said it shouldn't be a problem.)
I would try to just telnet to the port that you have open to
make sure the connection can be established.
telnet computernamewebserver 1935 (this should open up a
socket, otherwise your port forwarding isnt working correctly.)
If telnet works ok, perhaps its an issue with the swf. I
would code the minimal things needed to just get a stream playing
from the external network (perhaps just using the vod service, not
the live, to make things simple).
Hope that helps.

Need license for using H.264 Video codec for live stream with FMS 3.5 series

Hi,
I am creating a live audio-Video chat application in which I use H264 video codec for live streaming. I am using Flash Media Server version 3.5.7. I read some where that H.264 Video streaming using FMS required seperate licencse. So I want to confirm , It is true that H264 video streaming required seperate license? If yes then what is the procedure to get license.
Please let me know its urgent.
Regrads,

Hi Again,
Thanks for your reply.
Here are some articles/posts which says about Royalties to use h264:
http://www.mpegla.com/Lists/MPEG%20LA%20News%20List/Attachments/226/n-10-02-02.pdf 15:27

http://www.streamingmedia.com/Articles/ReadArticle.aspx?ArticleID=65403&PageNum=3
http://www.mpegla.com/main/programs/avc/Documents/AVC_TermsSummary.pdf
According to these, any product/service provider, need to pay one time fee based on # of subscribers if we are using h264 for encoding and is charging fee from its users.
About our business: We are web-conferencing solution tool provider and are using Flash Media Server version 3.5.7. I for audio/video. Please help me out if h264 is really free for us or we need to buy license to use that.
Looking forward to hear from you soon.

JVC GY-HM100u for live streaming

I want to buy the JVC GY-HM100u for live streaming at my local church. We want to be able to have the camera at the front of the church and have the laptop that we are using somewhere else.
Is this possible and if so how?
Also what laptop would you recommend for this type of task
(Live streaming a Church service and editing the recording later on)

First question I have is why do you want the camera at the front?
Second question is are you using the laptop for the web broadcast or recording?
Third question - what hardware are you going to use to get from the camera and into your computer, and what software to get it from the computer to the web?
My advice is stream in SD and run a composite video line from the camera to some sort of hardware that'll get it into your computer to stream out. What hardware you need depends on the software you use to stream. It's church - save a few bucks going SD, then donate what you save to a local charity. If you do anamorphic (widescreen) SD you'll probably convince half of your web viewers that it's HD. Check with your streaming provider about what needs to be done with anamorphic video. Don't forget to think about what kind of upstream data connection you need. Check with your provider to see what kind of sustained upload speeds you need. Do tests during the service to see what's available. If you have public WiFi sharing the internet connection you might run into issues sometime.
For your recording later on, just record to the camera's SD card slots. The JVC you mentioned records Quicktime movies that'll go right into Final Cut. This can easily be HD.
Make sure your audio is clean, it matters more than the picture. Get a feed from one of the audio consoles. If it's the front of house board (or the board if you only have one) ask for a Matrix, post-fade AUX, or Tape Out from the sound guy - though he will have an understanding of what you need already. You might look into some sort of auto-gain controller or compressor to level things off. You can have 12dB of difference between someone talking and a band play easily.
For the laptop - again it depends on your streaming provider. A desktop may be a better option for specialised hardware requirements.
I'm going to hop on a soap box here at the end for a second. I don't mean this offensively to your local church. I have no idea what sorts of programs you have in place or anything of the sort. That said, for a church I'd sit down and do a cost-benefit analysis on this before continuing. Sure, a live stream is cool, but given the cost that it takes to get it going I'd rather buy school supplies and hygiene items for kids that need them, or put some money into social justice. Chances are a live stream isn't going to change someone's life, but providing a village with clean water changes several lives. You could probably step away from the live idea, drop down to SD, and save about $4,000 initially, plus whatever ongoing costs web streaming necessitates. A lot can be done with $4,000.

How to use Phone camera for live streaming rather than using WireCast camera in Live streaming using Azure Media Services

Hi,
am planning to develop a live streaming app using C# and xaml.
I have gone through the below sample and am able to stream the live content using wireacst camera.
Azure Media Services Live Streaming Sample
But i want to use Phone camera to stream the live video rather using wirecast camera.
How can i use that? How to get the published URL from the C# code, is there any API to get that?
Anybody please help me
Regards,
Santhosh

Hello,
There are no in box components that will allow you to transmit captured video from a Windows Phone device to Azure Media Services. You will need to create you own implementation. You can do this by creating a custom Media Foundation sync that can plug into
the MediaCapture element's pipeline. You will then need to modify the captured and compressed video to align to one of the two protocols that Azure Media services can use. At this time Azure Media services can use either Smooth Streaming or RTMP for ingestion.
You will need to create your own packager (or find compatible packager code from a 3rd party) to package the MP4 encoded data into the necessary format.
Here is an example of how to create a custom Media Foundation sync (please note you must write your Media Foundation components using C++ MoCOM. We do not support Media Foundation components written in managed languages):
Real-time communication sample
I hope this helps,

Flash Media Player which handles bitrate switching for live streams?

Hello. I've got a very short timescale to find a solution for a way to display livestreams with bitrate switching. Does anyone
know of any opensource players which can do this effectively? Or do the inbuilt components in CS4 deal with this ok?

Thanks,I have read that article. Based on that article the NetStreamInfo.maxBytesPerSecond is not an accurate measurement to base dynamic switching on. This seems to be the basis of the bitrate switching in both the longtail player, and the adobe examples that I have tried. That article suggests using the dropped frames property, in conjunciton with bufferlength to determine if switching is neccessary. Unfortunately I can't seem to find a player online which handles this successfully. That being said, I can't believe I'm the only person trying to implement dynamic bitrate switching for live streams so surely there are some players out there which can do this successfully? If anyone knows of any code available which does this successfully I would appreciate knowing where! The examples provided by Adobe https://www.adobe.com/cfusion/entitlement/index.cfm?e=fms35 unfortunately don't work either.

Thanks for looking at this post. We have resolved the issue for ourselves by working with our DBAs to narrow down where the problem actually started. We found that the particular SQL we were looking at was not the issue. In a chart on a subsequent page (via a click through), we were actually running into where apex was starting to consuming memory but we were catching it later.
What we found was that when we had a chart query that was SQL containing a pipeline function, the memory usage went up. And within 10 minutes, the server would crawl to a halt. To release the memory, the DBAs would have to bounce the Apex instance. When I changed the query to be a function returning SQL, the problem stopped. I don't know what the correlation was between SQL and moving to a PL/SQL function returning SQL.
I am not even 100% positive of the pipeline function being the cause. I only know that this started happening about the same time as when I implemented the pipeline function. I understand you are leery of a one-second function/query running up that kind of utilization. No one here believed me either (including me really). We figured it HAD to be a coincidence. But once I changed the query from SQL to a function returning PL/SQL, our problem went away.
Thanks to all who looked at and thought about this.

Using Broadcaster with Internap CDN for live streaming

Has anybody successfully used Broadcaster with Internap's CDN for live streaming?
If so how are you configuring broadcaster?

What are your current settings in FMLE ?
What is your input feed? from webcam? external HD camera? Encoder card?
If your connectivity approved you can raise up the bitrate and set higher output size.

Having trouble watching live streams such as jtv and twitch.tv. I tried uninstalling/reinstalling adobe flash but I still get no stream just ads and pictures. Anyone have any suggestions?

Having trouble watching live streams such as jtv and twitch.tv. I tried uninstalling/reinstalling adobe flash but I still get no stream just ads and pictures. Anyone have any suggestions?

I just wanted to follow this up by saying that you were entirely correct in your diagnosis of the situation. My computer did have the faulty part you linked to. I brought my laptop in and specifically told them to run that test, had it fail and then argued with the person at the genius bar and the manager. Eventually they offered to have it sent out and have everything replaced for free of charge. They did so mainly because I had complained about graphical issues almost every other time I had come in with problems and no one ran the test. They should have caught this problem during my warranty, but they didn't, even though I mentioned the problem.
Anyhow, after having the part replaced, I haven't had my computer crash a single time since, or had many of the issues mentioned above. I've never had this experience before. Even brand new, I got occasional crashes. Hopefully this new trend continues.
I do find that web browsing is still incredibly slow. Web browsers just chug along at a slow pace, even though I have great internet speed. Maybe I'll try just deleting my web browsers and reinstalling them...
Anyhow, thank you for your help and knowledge Clinton.

How can I delete the video and keep the Audio in a few frames using Imovie 11

How can I delete the video and keep the Audio in a few frames using Imovie 11?

I've met the problem too before. but i solved it with Audio Converter Mac instead of iMovie. If you have similar situation that just want to keep audio but not video, and if your file format is not workable in iMovie, you can use the Audio Converter for help too. it can easily help to extract audio soundtrack from any video format. Or if you need to convert one audio format to another, it is a good choice too, because it supports many common audio output formats.

Can I author hi def HDV video and surround digital audio by sending a file

Create a bl;ue ray HDV video and surround-digital audio
Posted: Nov 2, 2006 10:43 PM
I have a MAC G5 dual processor, Final Cut Pro, DVDSP, and a home network connecting the MAC to an IBM PC with a Blue Ray Burner. You would think that wioth my Sony HDV camera, I could create HDV hi-def video material and a Dolby 5.1 or DTS audio track along with it and burn a Blue REay media and then be able to play it on a Sony Blue Ray player in my home theater.
Well, How do you do this? I have been wanting to create some of my own stuff and record like this so anyone with the equipment could view it.
Please RSVP

I recently made a dual layer disk on one of our G5s without a dual layer burner by doing the final burn on a PC. I imagine you could do the same with blue ray.
Just edit the project and make your hi def DVD on the MAC using FCP and DVDSP. In DVDSP Build the project to a suitable folder on the hard disk. Copy the files to your PC and burn the disk as a data disk with the burner software.

Creating a custom player for live streaming video

I have live streaming video set up where I use the Flash Media Encoder to send the live stream to a Flash Media Server. Then, the Flash Media server packages this stream, and sends it to whatever websites requests it via the url. I know how to create a Flash move or even asc file, and then have Flash generate the html for that saved movie so that I can embed it in a web page and play it. But in the case of live streaming video, there is no pre made asc file or movie to reference. So I need some help about what I need to do to play live streaming video in a flash player embedded in a webpage, that will also have some custom action script for controlling playback and other things.

About a half-hour after making the changes I outlined above, and long after I closed the active Safari window, noticed that my MBP was uncharacteristically hot. Extremely hot!
Opened Activity Monitor and saw that Flash Player was still running (?) and using a tremendous amount of system resources. I then quit Safari altogether. Within moments, the heat began to subside.
May be something you want to keep an eye on...

Offline image for Live Stream

I am new to using flash media server. I setup the server and using the default player for the live stream and when I am not broadcasting I want to display an image instead of the black box that comes up till I start the live broadcast. Is there away to have it pull an image when I am not streaming?

Hi,
When you said you are using the default player, did you mean the livetest.swf inside <fms-install>\applications\live ?
If so then that cant be modified since it has only .swf file. You may have to write custom client side player (swf file).
And also do you want to display any image or the last frame of the video before it stopped?

How to find metrics for live streams?

Hi there,
We have installed FMS and have used it for a live streaming video event. The event lasted an hour and FMS worked great.
How can I get statistics on that live stream? I'd like to know how many people saw the video, and how many people were watching at one time.
Can you please tell me where to find this?
Thanks

One way to check this is to use the FMS logs. The access logs in <FMS install>/logs folder contains all such information regarding events with time. With default logger configuration it records only certain events like connect, disconnect, etc. and fields related to them. To enable more logging make changes to the following tags in conf/Logger.xml
tag 1. Modify <Events> value under <access>. The value of this tag controls which events will be logged in access.00.log. Select the ones which you need. The information of all events have been provided.
tag2: <Fields> under <access> Similarly you can configure what fields you want to be logged for each event.
I understand this is not very straight forward as this log may get very large. So you may also consider using file parsers which may be available and use them to parse this file.
Another way is to use admin API commands. You can check the list of admin APIs listed in FMS documentation. These APIs may give you some information too and you can use the most suitable ones for your purpose.
Thanks,
Abhishek

H.264 for live streaming

Flash media encoder 2 only encodes to the on2v6 video
standard. Has anyone attempted live streaming of h.264? If so, what
worked (or didn't)? Any lessons learned would be appreciated.
Thanks!

I would like to know what is going wrong with my tries.
I’ve been trying to do live stream with Flash Media Encoder
2.5, but i cant conect to the server with it. It ask’s about
my Username end my Password, i put them right but doesn’t not
work. Comes, there is no such user. But i’ve been putting the
username from login of server and password fron the server…
…Thank’s for now.
