Video Streaming by UTP packet.

Hi all,
my case is that I am developing a prototype. On server side, when it receives a request from client , the server will push UTP packets containing video segments to client, say a video file 10Mb, every packet will be 1kB, and continuous to push the UTP packet until the end of movie.
On client side, of course, when it has received a certain number of packet and store into buffer, it will play the video on screen. I have not used any RTP classes in my work till now, and if available i will not use it.
Ok, my question is when I put the packets into a file, at this moment, my program starts a player to play the incomplete video file. And I continuous to put new incoming packets into the file, and the player continuously play the video. Do you think this approach work or not? I am thinking because the file read/write problem, while I am putting packet to file, it is not available to be played, right?
I
Would you please kindly give me any suggestion?
Thank you very much

No video stream when calling 3rd party endpoint from Jabber client

I use my own H323 client based on the H323Plus open source. It works very well with VCS and all endpoints we tried (a dozen or so from every vendor). We have a problem with Jabber Video though, across all versions from MOVI to 4.4.3. When my own client calls Jabber everything works as it should. However, when Jabber calls my client then (1) it takes up to a minute for Jabber to display incoming video and (2) Jabber does not create outgoing video stream. This behavior is 100% reproducible across all PCs we tried. Jabber is registered with either VCS Starter Pack or VCS Control, sofwtare version 6.1 in both cases. We do not use provisioning at this time.
In Jabber logs there is a unclear hint about insufficient resources (bandwidth?) for the video stream. VCS configuration is fine (it works with all other clients like e20) and I do not see anything useful in VCS logs.
To narrow the discussion, this is NOT a firewall, client camera or driver, OS misconfiguration or any other external issue. It is Jabber video having problem negotiating capabilities and/or resources but only it initiates the call. Where should I look for a solution?

I was afraid this will end this way. I hoped you might have had such a case solved already :-).
Audio works fine, no problem at all. The video packets are not sent from my client to Jabber while in the 1 minute wait; the stream from Jabber is not even started. I still think I need Wireshark to decode H225 traffic. Good idea with the interworking log - I was too lazy to go the OS layer. As you surely know, only 2 of the VCS logs are available from the Web interface.
thanks for your help!

Saving video stream from webcam periodically!!!

Hi there, I want to catch every 1 minute video stream from the webcam, or video file, and save it into separate files. Of course I woudl like to have possibility to save many streams simultaneously. Any idea?
Best regards

Hi,
I want to do the same thing ... I was able to stream audio through the socket but could not stream video.
I posted my question at http://forum.java.sun.com/thread.jspa?threadID=674676&tstart=15
and presented a sketch of my implementation design. But until now no one has answered my question.
This is how you should hook up the components on the transmitter side
Webcam --> Processor --> Custom DataSink --> PushBufferStream --> PushBufferHandler --> Socket --> Network.
You can implement the transferData() method of the PushBufferHandler to write to a socket.
And on the Receiver side the components should be hooked up like this
Network --> Socket --> PullBufferStream --> custom DataSource --> Player
Now as I mentioned in
http://forum.java.sun.com/thread.jspa?threadID=674676&tstart=15
the audio works fine but the video does not. The video does not render on the receiver side.
Note: I tried TCP sockets with audio and it is terrible (not practical at all) so I reverted to UDP datagrams and the result was better than I expected. I didn't take care of the ordering of received packet at the receiver but it still worked fine.
I am still looking waiting for some help in why video is not rendering and how can I sovle this problem.
I am workning on a project and time is running out.
Any help?

Help implementing QoS for Video Streaming

Hello friends!
I am trying to implement a quality of service logic for a videoplayer based on the Brightcove API. As I have learned it's a better idea to use methods in NetStreamInfo class (eg. currentBytesPerSecond) rather than using a native bandwith check.
E.g. (where nc is a NetConnection object)
var ns:NetStream = new NetStream(nc);
var nsi:NetStreamInfo = ns.info;
var cbytes:Number = nsi.currentBytesPerSecond;
use cbytes to evaluate which quality to chose...
The problem is that streams are initiated (by videoplayer) using the Brightcove API and not directly using NetConnection.connect(). The BC API doesnt seem to give me any access to the classes listed above either, altough I'm certain it's utilizing them.
Are there any Brightcove or video streaming experts out there that have a clue as to how I can access the NetConnection object used by Brightcove? Or if i can access the NetStream object or even tge NetStreamInfo object directly.
best regards,
Fredrik

You don't have your egress queuing setup. You need to map your COS values to a queue, then you can allocate bandwidth to those queue's. This makes lower priority traffic wait while higher priority traffic gets transmitted.
I have a few configuration examples on my site that may help you. Remember that the config that I have may not be the best for your network so you will have to figure that out yourself.
http://goatnetworking.com/CiscoCSwitchQOSConfig.php
Make sure that your QOS profile on the WLC is set correctly. I found one of my controllers didn't even have a value set in the profile, but the profile was applied and doing nothing.
You need to apply the policy map to mark packets on the port where the video source is on your network.
You need to Trust DSCP on all of your trunk ports or the switch will ignore the dscp markings.
QOS may only be one of many issues that may be causing your problem. Your AP's could be overloaded with clients, your data rates may not be optimized, etc..
I hope this helps

Site to site between 892s, video streaming, fragments and dropped traffic

Customer network consists of two LANs, each routed from an 892. The 892s are connected by a Gig fiber path, and there's an IPSec VPN between the 892s. All traffic from one LAN to the other traverses the VPN. Site 1 has a Lenel video server with a bunch of cameras streaming video to it. Site 1 and Site 2 each have a Win7 PC with some Lenel software that receives video streams retransmitted from the video server at Site 1. The video server streams the video as UDP.   The client PC at Site1 receives all the video streams from the server just fine. The client PC at Site 2 does not reliably receive the video streams from the server at Site 1. Streams from *some* cameras are received fine, but not others. Looking at Wireshark captures taken at Site 1, it looks like most of the UDP traffic is fragmented.
Anyone else out there have anything remotely like this setup, and any notions of where to go looking for why Site 2's got such issues?
I'm afraid I'm somewhat constrained by all sorts of legal and bureaucratic restrictions on exactly what configuration and sample data I can include in this discussion, which would make me laugh if it wasn't so frustrating (this is a network of security cameras around a sensitive research facility).

Hi Julio,
Everything seems to be ok in this access list. I think this is a routing issue. It is just does not know where to send the packet back or where to reply.

With SilverLight, Microsoft created their own version of what a replacement for Flash could be - but not to universal acclaim. You can read more about it here:
http://silverlight.net/
So, if you go to any sites that have been designed for this Silverlight stuff, you can download the plug-in from there (but make certain that you are downloading SilverLight v.1.0 for OS X (10.4.8 upwards) if you are using a PPC Mac, but even this will not work with Safari 4. Version 2 only works with Intel Macs and does work with Safari 4/5. The solution is to download and install the latest version of Flip4Mac, which now includes a Silverlight component:
http://dynamic.telestream.net/downloads/download-flip4macwmv.htm
But the latest news is that Microsoft will probably abandon Silverlight in favour of HTML5:

Using Labview to process a video stream and detect a color range

My boss has challenged me to come up with a solution to an interesting problem. He wants to know if we could drive a vehicle around with a camera mounted on top pointing at various angles from the horizon and up and then process the video to determine how often we are seeing the sky and how often we are seeing a building or some other "blockage".
I currently have the Full development version and I told him we would probably need the NI Vision module but maybe someone can suggest another tack or at least tell me if I'm on the right direction.
Don Lafferty

Hello friends, I can receive the video stream in my laptop but I only can show noise. Maybe the problem is the type of image or the order of the data (as far as I know It is jpeg format with 320x240 pixels, 24 bits).
I discovered that images' size changes dinamically (they are not fixed to 320x240=76800 pixels) due to the jpeg compression. Bu It is not a problem, because I basically assemble the data packets arriving over TCP/IP and identified by headers ("Content-Type:" and "Length-Type:"). I am discarding the content-type & content-lenght headers. After this
I convert the string into a byte array and once I have the byte array, I plug it into a picture indicator (but only white noise).
I didn't try IMAQ ArrayToColorImage function because it needs a 2D array to is input terminal (vertical and horizontal axis) but I only have available a 1D byte array from my input string. How can I convert it to 2D? I don't know if it is the correct direction or I am away.
I hope I can attach the VI this time.
Thanks.

Can I see video stream from a website on my tv from my desktop with apple tv

I am trying to watch a weekly video stream from a website using my Mac desktop on my tv with Apple Tv..can I do this?

If your computer is a Mac and new enough (2011+) then maybe. See required specs here:

HT3819 video stream from amazon prime to my TV

i want to video stream from amazon prime to my TV via my ipad, mac book using my apple TV device..

there is no reason to get rid of Apple devices, not when a Chromecast, Roku, or FireTV can be acquired so cheaply.
This is a true statement, but this is a bad option in the long term since your content will be split between different sources, DRM rules, apps, access options, etc. You are going to constantly be running into issues were you want to watch a show that is not available on the device (phone, tablet, etc) you are on. I share "Disgusted_with_apple" frustrations in that Apple has not updated in three years now leaving Amazon FireTV and others with better interfaces and features but having my content locked into Apple's DRM.
Apple was really first to market with a viable TV interface device, and has completely turned the market over to its competitors just by not showing up. And now ATV can not play content, or provide features that ALL of the competitors have. I recently bought an Amazon FireTV and love it. The only advantage Apple has left is the iTunes Store still has more content, but that is not likely to last.

SpryTabbedPanel: Flash player in tabs do not play video streams

Note: I am a complete noob (no experience with Javascript and rudimentary experience with htlm/css). Please be patient (I hope that this is the correct forum for this) and know that I am appreciative of any help or solution that anyone can provide.
Using Dreamweaver CS4 on Mac OS 10.5.8
We recently switched all of our streaming servers from Windows Media (good riddance) to Flash Media Server 3.5 (now getting awesome H.264 quality in comparison).
I was asked to re-design this webpage with the aim of re-organizing the content so that it is more accessible:
http://www.librarymedia.net/VideoGallery.html
We used Adobe's test page for our first page:
http://www.librarymedia.net/flash/videoplayer.html?source=rtmp://63.116.232.4/live/livestr eam&type=live&idx=10
This was meant as a temporary page to get us started, and as you can see, it needs work but at least it works.
I've been working the the final version of this page. My boss wants a tabbed web page with links to our video streams (tab for each category of streams).
This is what I have so far:
http://www.librarymedia.net/Flash2/videoplayer2.html?source=rtmp://63.116.232.4/live/lives tream&type=live&idx=10
I realize that I had several options before building this. One, I could have made a separate page for each tab and linked them with a tab menu. In hindsight, this might have been a better option since I could have just copied the working page that we already have for each tab. Or I could have done what I have tried to do: to use Dreamweaver's SpryTabbedPanel to make the tabs and insert a Flash player with links into each tab.
The problem:
1. The streams do not play. The player says "initializing" and then "please enter a stream name and play". Please note that I used SpryURLutils to get each link to open in the appropriate tab.
2. After reading about the benefits of external vs. inline javascript, I took all of the inline javascript that was contained in Adobe's sample page and placed it in an external file. I tried placing the javascript back into the source code (inline), but this did not fix the problem. I guess there is a Javascript problem or I need extra Javascript code to get this to work. The javascript code is below. Use view source in your web browser to see source code. Please let me know if I need to provide more information.
Thanks.

>There is a sample application of the code included with the zip file which shows how to implement it.
The sample doesn't really tell me what I need to do to the code to make it work (I do not know javascript), and unfortunately, I have not found any helpful instructions/documentation online. You've given me the answer, I just don't know enough to implement it. This is what I've done:
1. Placed the FAVideo.js file in my site folder and linked it to the page: <script src="FAVideo.js" type="text/javascript"></script>
2. I added the following code (taken from the SimpleDemo.html example inside the FAVideo folder). My comments in bold. Page at
http://www.librarymedia.net/Flash2/videoplayer2.html?source=rtmp://63.116.232.6/vod/mp4:Ol ympics2010_640x480.mov
         <! To the <body> section:-->
<body onLoad="">
    <div id="divOne"></div>
<!-Do I have to place the entire page within the "divOne" div (or just the section containing the tabs) in order for the javascript to work?-->
         <!-In the <head> section: -->
   <script type="text/javascript">
        playerOne = new FAVideo("divOne", "TabbedPanels1", "demo_video.flv",0,0,{ autoLoad:true, autoPlay:true });
    </script>
<!- I noticed that the body code added a div id called "divOne", so I added the "TabbedPanels1" div id to the above code thinking that this would apply the javascript code to all of the tabs. Dreamweaver adds <div id="TabbedPanels1" class="TabbedPanels"> to the page when you insert the tabbed menu, so I'm thinking the javascript has to point to either one of those for it to work. The "demo_video.flv",0,0 code is probably unneccesary, right? As you can see, I'm completely clueless. -->
    <script>
        playerOne.addEventListener("playheadUpdate",this,myHandler);
        playerOne.removeEventListener("playheadUpdate",this,myHandler);
        function myHandler() {
            //alert("eh");
    </script>

CTD bug in simple video streaming applet.

I'm trying to write a simple applet to use JMF to allow an end-user to view a video stream that's being served up by VLC. It doesn't have to look immensely pretty (in fact, streamlined is what I want most). I swiped some code from the jicyshout project (http://jicyshout.sourceforge.net) which handles streaming MP3s, and borrowed a framework for an applet from one of Sun's example applets for the JMF.
Here's my code so far:

* extended for our puposes.
* This is a DataSource using a SeekableStream suitable for
* streaming video using the default parser supplied by JMF.

// Make the stream seekable, so that the JMF parser can try to parse it (instead
// of throwing up).

Now, I'm still new to the JMF, so this might be obvious to some of you... but it's exploding on me, and crashing to desktop (both in IE and Firefox) with some very fun errors:

siginfo: ExceptionCode=0xc0000005, writing address 0x034e6360
(plenty more here, I can post the rest if necessary)
The problem seems to be coming from the "return seekStreams" statement in the first file; when I have execution aborted before that (with a fatalError call), it doesn't crash.
Any tips/hints/suggestions?

You should write your own Applet, where you can easily get the visual component (getVisualComponent())and show it directly in your Applet (you call it "embedded"). As far as I know, all examples (AVReceive* etc.) use the component which opens a new window.

Remote video streaming not working with Windows Server Essentials Media Pack

I installed Server Essentials Media Pack and the video streaming via remote access does not seem to be working. I see all the video files on the server's remotewebaccess page in "Media Library" group. When I try to play the video in Chrome
the player appears for a brief moment, but then the browser starts downloading the entire file. With Internet Explorer the empty browser window opens and the download starts. I am trying it while outside of my local network. The video streaming used to work
with Server 2012 Esesentials. Am I missing some additional codecs or remote streaming is no longer supported?

Hi,
What’s the default player for these media files on your computer? The issue may be caused by the default player could not load the media file correctly. Please make sure Windows Media Player
with full codec installed is the default one. And then check if the media streaming feature could work as normal. Here is an article about how to configure the media streaming feature, hope it helps.

No audio video streams upon import of .mov files?

Hi... recently upgraded OS onto Intel 240 GB SSD. Running Widows 7 64 bit, clean re-install, 24 GB RAM, NIVIDIA Quadro FX 4800. I have been trying to optimize the system for maximum GPU accelerated effects while also taking advantage of the high speed read and write of my disk. OS runs on SSD, Adobe media cache on separate 2 TB eSATA connection, Media stored on external drive USB 3.0. Without getting into the fine details this is a snapshot of my workflow.
The few problems I am encountering are some .mov files cannot be imported to PP. Error reads no audio or video stream in the files. I suspected metadata issues so tried to import with media browser and still no luck. These files worked perfectly before I began surgery 2 days ago on my computer. I have installed the latest version of quicktime and yet to no avail. Any recommendations here regarding my issue with imports or suggestions to benefit from my hardware would be appreciated.

MOV is a wrapper, what is inside YOUR wrapper - Exactly what is INSIDE the video you are editing?

.Mov files in CC : The File Has no Audio or Video Streams

I recently updated premier to CC , since i have issues iimporting any .mov files at all.
The specific ones Im trying for my current project are exports from AE , rendered lossless animation .mov , worked fine in CS6 , will play in quicktime and other generic's but always getting the The FIle Has no Audio or Video Streams message when trying to import into a project.
Quicktime is updated so I can't understand why the won't play, is this a CC bug ?
i go back to cs6 on my other comp they open fine...
Ive seen a few topics on this none with a resolution and most of those where from cam's, this is an export from AE, anyone able to help this is stopping me from working atm ......

I can verify that Apple screen recordings without audio do not import into any Adobe premeier.
Details on screen recording from Gspot v2.70a:
H.264
qt : Apple QuickTime (.MOV/QT)
File Type: QuickTime (.MOV)
Mime Type: video/quicktime
Len: 1:03.083
Frms: 1,521
Qf: 0.153
Frames/s: 20.000
wx: 1280 x 800
sar: 1.600 (8:5)
However Apple (MAC OSX) screen recordings WITH audio will import.
I would think this should be fixable with hotfixes...
If you (adobe staff) have access to macbook pros 2012 or 2013 models, open quick time pro, do a screen recording, make sure no audio is recording, just your screen movements.. then export to 1080p video (mov is only option).. then on a windows PC try to import that file into adobe premiere. The file will play perfectly fine natively in windows with any player so long as a H264 decoder is available on that system... the problem here is Adobe Premiere. Not the users system.
Edit:
To help those with this issue.. just make sure when you render your mov that you have ANY kind of audio in it.. and just remove the audio track once imported into premiere. I know it's frustrating and you would think something as simple as not having an audio track wouldn't break premiere but alas... we have to work around the shortcomings until they decide to fix it.. just like the VFR issue in premiere.

Video streaming stalls in full screen mode

I'm not sure to be in the right category, but my Laptop runs in Tiger and I happen to use video streaming from different websides like ESPN Live and other websides with their own players. I use even some that require a program dowload to be able to see their content. By all those sources the video runs pretty smooth in a normal size. As soon as I put it to full screen it stalls in a certain rhythm no matter if the whole program is buffered or not.
I achieved better results with one of the providers using WMP that via flip4mac streams into Quicktime. Just don't know if and how I could incorporate those other webside players into Quicktime. And if this would be the solution.
I freed up some of my HD to achieve better performance. Have 18 GB free out of 100.. is this too little ?
Do I need a better video card ?

Ba,
It may be of interest to know that streaming video codecs are designed for computers of a specific age (CPU and GPU speeds).
DVD quality streams MPEG-2 compression at about 10 Mbits/sec, and the older MPEG-1 compression, designed for NTSC television, streams at about 2 Mbits/sec. At 10 Mbits/sec, the processor must work faster to decompress & display the image. The latest compressions are based on MPEG-4. Even a G3 iBook could display MPEG-4 full screen; so I don't think you need a faster GPU.
Microsoft codecs & containers, the last time I checked, were ancient: based upon MPEG-2. So, check your speed:
DSL Reports speed tests

If you use Wi-Fi, IEEE 802.11n is fastest.
Increase the cache size for your codec, if you can. It needs to be contiguous, so I dare to recommend iDefrag 2 (US$30) to clean your remaining disk space and obtain about 20 GB of contiguous space. Video display uses many operating system files, which are likely not fragmented; but you can also de-fragment the Windows codec if it lies in over 100 fragments. (The Spotlight database usually has over 1000 fragments; but pauses in it don't affect one's pleasure in using it.)
My low-resolution DVD is interpolated by my graphics card, and look beautiful at maximal resolution. Streaming graphics apparently isn't programmed to interpolate low resolution: it demands high resolution and high bandwidth.
If you can't increase the cache in WMP, you can lower the resolution of your monitor. That may be why this System Preference was designed to sit on the desktop's top bar.
