Streaming video over http

Hello
I need your help to understand how streaming over http works
In our company we have about 600 users who will be able to view streaming video over http hosted in Internet
We have 100 Mbps Internet link . What can we expect to happen in the network when there is contention for resources to access video on our network which delivers best effort service for video
We have enough bandwidth 4 gigs in local area network to core , so there's no real bandwidth cruch
How to differentiate or monitor bandwidth used for http streaming as against http normal traffic
Sent from Cisco Technical Support iPad App

One step closer:
Changed the crossdomain.xml file (more permissive settings).
Changed the encoding on FMLE to vp6. Working somewhat (don't know what I did to make it start streaming through hds).
But at least now I can get the individual streams in the set manifest file to work:
http://localhost/hds-live/livepkgr/_definst_/livevent/livestream1.f4m
http://localhost/hds-live/livepkgr/_definst_/livevent/livestream2.f4m
http://localhost/hds-live/livepkgr/_definst_/livevent/livestream3.f4m
BUT when I try to play the streams through the set manifest file from http://localhost/liveevent.f4m I'm getting the following error:
"The F4m document contains errors URL missing from Media tag." I'll search the forums to see if anyone else has come across this problem.
I used the f4m config tool to make the file. These are the file's contents:
<manifest xmlns="http://ns.adobe.com/f4m/2.0">
  <baseURL>http://localhost/hds-live/livepkgr/_definst_/liveevent/</baseURL>
  <media href="livestream1.f4m " bitrate="200"/>
  <media href="livestream2.f4m " bitrate="500"/>
  <media href="livestream3.f4m " bitrate="1000"/>
</manifest>
Thanks

  • Loading a video over HTTP

    I'm having problems loading a .3gp video over HTTP. I get the
    following error message "Error preparing video for playing".
    Everything else (xml data, images) loads nicely. I've tested
    this with Nokia 6630 and N70, but with no luck.
    If I transfer the files to my phone and load the video from
    the memory card, it works just fine. Is there something I can do to
    fix this?

    Ciao
    the defualt streaming protocol for Nokia is rtsp not http. So
    it will not work an http call to a video.
    Also using rtsp requires a streaming server, it's not enough
    to place the video file on the server.
    Other phone might use http for streaming.

  • Streaming videos over home network (KDE)?

    What do I need to be able to stream videos over home network in KDE?
    I tried to do it with ssh, both graphically and by terminal (Network>AddNetwork>ssh) and it didn't work. It tried to download the file. I was reading this is some kind of bug in the KDE.
    What else can I use to stream videos? Samba? Avahi?

    IMO, it would be best to abandon SSH completely. Its going add undesired overhead to this project.
    I use mediatomb to stream content to PS3 and HTPC running Arch: https://wiki.archlinux.org/index.php/Mediatomb
    If you just want to be able to access files locally from a remote server, use NFS to mount the desired remote folders: https://wiki.archlinux.org/index.php/NFS

  • Facing Problems in Streaming Video over internet using FMS 3.5

    I,am using FMS 3.5 to stream video over internet.This video will be a part of a website www.mywebsite.com . I have the webserver in my company. This webserver has the local LAN IP : 192.168.10.19 which is binded with a public internet ip 212.77.xx.xx .This website is hosted using IIS 6.0 on OS windows 2003 server with SP2
    I created a swf name sample.swf from sample.flv file and gave it the rtmp address as follows:
    rtmp://192.168.10.19/vod/_StreamingVideo_/sample.flv   (where _StreamingVideo_  is the instance on the server, and 192.168.10.19 is the LAN IP of server) ,and it worked fine and every one within the local company network could see the streaming video. Now i tried to replace this local address with the public address and the address became as follows:
    rtmp://212.77.xx.xx/vod/_StreamingVideo_/sample.flv
    After giving this public IP in the rtmp address i,am getting a message "Failed to load Flv from the address rtmp://212.77.xx.xx/vod/_StreamingVideo_/sample.flv" and as as result the video is not streamed and it only shows the progress bar on the link
    www.mywebsite.com/VideoStreaming/Sample.html without loading the video. I have also checked the ports 80,1935,1111 on the server and they are open. Is there any problem with my rtmp address with public IP or any other reason ??. Please help me out in this regard because im realy stuck here.

    Adding to my previous post this is the XML output i get when i try to access the fms admin console from local ip address i.e http://192.168.10.19:1111/fms_adminConsole.htm
    <?xml version="1.0" encoding="utf-8" ?>
    - <result>
    <level>error</level>
    <code>NetConnection.Connect.Rejected</code>
    <description>Admin user requires valid username and password.</description>
    <timestamp>2/3/2010 8:26:08 AM</timestamp>
    </result>
    but when i try to access fms admin console through public ip (http://212.77.xx.xx:1111/fms_adminConsole.htm) then it gives me the following :
    Internet Explorer cannot display the webpage.
    Any more suggestions Jay (because really ur the only one helping me out in this so far) ??

  • IPad air has trouble streaming videos over Wi-Fi when Bluetooth is enabled

    With Bluetooth enabled several video streaming apps have trouble. Videos are intermittent and choppy. But when I turn Bluetooth off, the problem goes away immediately. I'm streaming videos over Wi-Fi, and I tried changing the channels of the Wi-Fi network, but nothing seems to help. I've also tried switching video streaming apps with no difference. Has anyone else noticed these problems with Bluetooth?

    Hey,
    I have the same problem!
    Apple, do you have an answer for this? How can we fix this?

  • Stream rather than download videos over HTTP

    I have a home-built NAS server running a custom Web server.
    When I click an MP3 file from my NAS, it streams in Safari. It does not download, which is fine, and actually the behavior I want. (If I need to download, I'll right-click and choose Download.)
    But when I play a video file, it simply starts downloading it no matter what I do.
    The only solution I have for streaming video off my NAS is to copy the link to the video with a right-click, open QT Player, bring up Open Location and paste the URL. QT Player streams the video just fine.
    I'm guessing this has either to do with a MIME type issue or a headers issue, and not a Safari configuration problem. I can't find any settings that would allow me to change this behavior in the Safari UI.
    What I want to happen is for the video file to play in the browser window similar to how MP3 files do. I have seen this happen properly on older Safari builds accessing videos from public web sites, so I know it's possible - unless Apple removed this ability for some deliberate reason recently.
    Since I have control over the Webserver, I could change the MIME type it sends for m4v files. I just don't know what I should change it to, or if it's even possible to modify Safari settings in such a way to make streaming in-browser the default behavior.
    Is this possible to do?
    Thanks!
    F

    Yes, turned out my web server was giving the generic "application/octet-stream" mimetype. I told it to issue "video/mp4" and that seems to have worked. video/x-m4v also worked so maybe it doesn't matter which.
    Solved!

  • Anybody transmit video over HTTP?

    use JMF to transmit video stream over HTTP but not RTP

    I'm trying to do just this at the moment, to try to implement a low bitrate videoconferencing application. It is possible. The people behind Microsoft Portrait did it successfully. Check out their white paper at http://www.acm.org/sigs/sigmm/MM2001/ep/li-demo/.
    But I don't have any idea how to do it. I'm not too good at networking stuff. Any help I can get?

  • Streaming video over WiFi very slow

    Hi, I started to dealing this unpleasant issue since I guess I updated to last firmware on my Apple TV. Now when I want to stream video from my MacBook or iPad over wifi, the picture is not fluent at all. It is cut (not sure about this word). When I connect my MacBook through ethernet cable, it works just fine. Apple TV is connected by cable to my network.
    Anyway I was able to stream practically any movie in any quality and it worked. No I cannot stream nothing at all! :/
    Does somebody experience the same issue?

    If you have an Apple Store nearby, book an appointment with the Genius Bar and get them to check it over.
    If you don't have an Apple Store nearby, take it back to the retailer and explain what's happening and see what they have to say.
    Or, you could call Apple Tech Support give them the details of the problem and see if they can suggest a fix.
    Before doing any of the above, you might want to try restoring the iPad to default settings and then set it up again (back up your iPad prior to this to preserve apps and date etc) to see if this rectifies the issue.
    Hope you get it sorted

  • How can i stream video over apple tv from Macbookpro?

    I can stream video(youtube) off my Iphone, but not Macbook. On my Iphone an icon shows up for some video streams that allows you to select appletv to stream the content to tv, but I don't see that same Icon when browsing and playing youtubes or video on my macbook.???

    Unfortunately with that speed you are not going to have a good experience with HD streaming. I would make sure everything is set to stream SD. Go into the settings - iTunes Store and you can switch there for any purchases/rentals made through them.
    If you use Netflix (or other streaming sites) go into your account(s) and see if you can switch to a lower quality stream. I know Netflix has that in place.

  • Streaming video over TCP (sockets)

    We are trying to stream only video files between a client and a server, but we don't know how. We are using sockets TCP to connect both systems and we would like to know if exists any class in Java that could be helpful for us, or if any of you has created a source code that could help us and give us ideas about how to continue.
    Thanks in advance

    If you want exact representations of the video files, that is, bit for bit equality from end to end, tcp is fine. But you say streaming, so you will want to have a look at the UDP. This transfer doesn't care if some bits are lost along the way.
    If you want tcp, you should use RMI to transfer your files.

  • FMS 3.5 and steraming over http

    Hi, I've install FMS 3.5 development with Apache server
    option, on my Windows XP . I want to stream a live video over http
    ( so I be able to open it from a web browser). I'm using FMLE to
    encode a live video and and I'm sending it to the default folder
    "rtmp://myFMSserver/live" with the default name "livestream".
    From the instructions, I've understand that to be able to
    view a live movie over http I've to change the LIVE_DIR
    in <FMS_Installation_Dir>/conf/fms file and tell it to
    point to <FMS_Installation_Dir>\webroot\live_recorded folder.
    I downloaded the beginner_live_fms3.zip example files and
    copy live.html live.swf and live.fla to \webroot\live_recorded
    folder and in parallel I started to stream my "livestream" movie
    from the FMSE. Here is my problem:
    when I using my browser from the FMS server itself and use
    the followings
    http://localhost/live_recorded/live.html
    I'm able to see the live stream, but when I'm using a remote
    computer with the followings
    http://myFMSipAaddress/live_recorded/live.html
    I just get a blank white screen.
    I'm doing it in my own network so there is problem of
    firewall block problem. Any help we be appreciated.
    Thanks

    Hi,
    I have FMS 3.5 and WAMP running no problem.
    It might be a good idea to remove and reinstall FMS 3.5 and
    allow the Apache to be installed.
    It isnt a core version of Apache and it does not have any
    effect on my Webserver also running Apache, where FMS 3.5 is
    installed also.
    It seems to be a self contained package to run on the vob
    folder in the webroot directory of FMS 3.5 only
    I'm using it to test applications before deploying to the
    webserver.
    I think its main application is to display the sample pages
    which generates the code automatically to copy and paste the new
    Videoplayer for your own movies.
    I hope this helps.

  • IOS Safari wont play quicktime over HTTPS

    I have a video that streams from Apache (Mac Web Sharing) OK to Mac OS X Safari and Firefox, and to Safari on my iPhone and iPad.
    However, when I put the same video on a Mac OS X Server with SSL enabled (self-crtificated) I can view the video via Mac OS X Safari and other browsers using HTTPS, but not on my iOS devices.
    I have recreated this problem on multiple servers and clients, and my client is also seeing the same thing (same video streamed from an IIS/SharePoint server.)
    Can anyone shed light on this?
    Regards,
    Paul Adams,
    Vancouver, BC.

    Having the same problem. Here should be a solution https://devforums.apple.com/message/361209#361209
    It says following:
    After experiencing the very same problem and symptoms, I was able to gain access to the Apple Developer Forum thread mentioned here (https://devforums.apple.com/message/361209#361209)
    The upshot of the Apple thread is that you must have a valid Intermediate Certificate installed on the server. It is not enough to have only the server certificate installed.
    I have tested this with Mac OS X 10.6 Server. I installed the server certificate and while desktop browsers were able to stream a video over HTTPS, iOS devices (iPhone and iPad) both gave the "This movie could not be played" error.
    Installing the Intermediate Certificate fixed the problem.
    Other devices, like Android phones and tablets, and RIM PowerBook (via Flash) had no problems playing the video without the Intermediate Certificate. I suspect it is a case of iOS being overzealous with its security, a "Feature" if not a bug ;-)
    My question is: Where and how do I install the Intermediate Certificate? On the iPhone or on the Apache Server?

  • How can I stream video from my computer to my tv?

    I want to know if and how I can stream video over my wireless network from my computer to my internet ready Sony TV.  The TV is connected to an Airport Express.

    Well you could go with the Apple TV, or you could just use the streaming functions built in to your Sony TV. As I don't know about Sony smart TVs I can't tell you anything about the TV's streaming functionality.
