HD or SD Camera for web streaming application

Looking to buy a couple of cameras (and FCE) purely for creating video for web streaming.
Given the video will be highly compressed for streaming, is there any benefit in going HD over SD?
With thanks
Bob

CosmoPod downloads the original file format (which can be retained), then converts to either MPEG4 or H264 (Best or Better). The file conversion is dependent on your Preference settings.
For functional purposes, CosmoPod places a Tool Icon on your Toolbar. Plus, the download/preference panel can be accessed via the Window menu. Videos can be directed to a Download location, or directly to iTunes.
Whether or not a file can be downloaded depends on file accessibility permissions on the provider's end. Trial version gives you 5 days/10 videos, which ought to give you a sense of whether it serves your purposes.

  • Built-in support for web streaming camera?

    Hi,
    I have a Sony MiniDV camcorder that supports web streaming.
    Is there any built-in software support for web streaming?
    If not, could someone please recommend software that will allow me to setup my camera in my house and view the streamed data over the internet?
    Thanks!!

    You can download Quicktime broadcaster for free to do this. See http://www.apple.com/quicktime/broadcaster/
    We've used it to stream a live event from an art gallery and then to a Quicktime Streaming Server (available free in the Darwin version) to broadcast to the world.

  • Exporting for Web Streaming...

    Hello - what are the best specs to export a file for Web Streaming? My client gave me the specs of 640x320, and it's too stretched. Also, would it be in Sorenson? MPEG-4? Something else? Thanks so much!

    But H.264, good to know that that's the 'standard' setting for Web Streaming... ,
    There are no standards for Web streaming. None. H.264 is a convenient place to start but only because Flash will see it and Microsoft's latest products sometimes do.
    Streaming is often confused with but can be wildly different from unicast, multicast, download, and live viewing.

  • Using CSS for Web dynpro application in EP

    Hi,
    I have some CSS (Style sheets) which I need to apply to the portal, so that all the web dynpro applications can have the same look and feel.
    I read something about Theme Editor in EP. Can I somehow use that to import the CSS contents into the EP theme?
    Any pointer to using CSS for Web Dynpro applications will be appreciated.
    Thanks.

  • Create iView for Web Dynpro Application

    Hi guys,
    I've created a Web Dynpro Application via NWDI and deployed to the j2ee server. Now, I'm trying to create an iView to link to that application. The steps I've done are:
    1. Create iView for Web Dynpro Application
    2. Select "Create iView from each application View"
    3. Select my application.
    That's when the error occurs at step 3. I select my application and click next, but an error msg keeps appearing telling me to "To continue, select at least one application" despite having already done so. Can anyone enlighten me on this? Thanks!
    ZHenmin

    Hi,
      First make sure the applications runs fine standalone. Also the versions for WAS and EP are maintained correctly. Actually, this error seems to be occur for many users. Check this thread too.
    Open new Web Dynpro iView in EP7
    If nothing works, restart the server and try creating the iView again.

  • Can anyone help me with compressions for web streaming? So lost!

    Hi there
    I am so confused !
    I have the task of getting HD footage from my camcorder ready for quality web-streaming on a website. The clips need to be in mp4 format using the H264 codec. As we are dealing with HD footage, I want the viewer to be very happy with the picture quality. I must admit that most of my compression settings were kind of guess work and I was only judging my results by the final file size in relation to the video quality. I was getting file sizes of about 16mb per minute of video/ audio footage.
    I had been keeping my frame size at 1280x720 and my bit rates were about 2000-2500kbits/s. Bandwidth is a real concern as there will be alot of people streaming these videos and there might be over a hundred videos on offer at any one time. I found that bit rates any less than this were resulting in a poor picture quality.
    I have since learnt that what I was doing is completely wrong!
    I was told that my frame size was way too big for normal web-streaming of HD footage and also that my bit rate was too high and bandwidth hungry. I never knew that the bit rates I set when compressing my videos would have an effect on the bandwidth that would be used. I am obviously showing my ignorance!
    If anyone has anytime to help out someone who has no idea, I would absolutely love to know the answers to these questions:
    1. What is considered a good acceptable frame size to show HD quality footage? Maybe a size that if the quality is OK, they can also stretch the frame afterwards to fill their screen without losing too much quality?
    2. I want to use mp4 with the H264 codec for streaming, what is an efficient bit rate to set the compression at, so that the quality looks nice, but wont drain my bandwidth unnecessarily?
    3. Can anyone explain how the bit rates that I set for my compressions affect the way they are downloaded once they are on a website. Just cant get my head around this logic for some reason?
    4. What other compression settings should I be aware of (eg. keyframes etc)
    I feel so lost in all of this and would appreciate it tremendously if anyone can help me out.
    Dan

    If I select a bit rate of say 2500 to compress my videos at, what will that now mean for the end user? Will that mean that his connection will be forced to download that video at 2500kbp/s thus using alot more bandwidth?
    Yes and no. If the end user has a connection that allows them to receive data at 2500 and the source from the web can supply data at that speed then they'll be able to stream in real time. However, if either end doesn't hold up (the client's connection can't receive data that fast or the source can't send it) then end users will be forced to watch it on delay - letting a good portion of the movie download first. QuickTime will do this anyway - if you (as I do) embed a movie into a webpage, when you visit that page QuickTime will calculate how fast data is being sent and received, and decide when to start the movie based on that calculation.
    I was told that the bit rate I set when I compress these files locally on my machine, tell the streaming software how to allow users to download them - is that true or have I got all mixed up?
    You keep saying streaming and I'm not sure exactly what you mean. Streaming can either mean having a finished file on the web that people can watch with minimal downloading in advance, or streaming can mean sending a live event out over the web. I think you mean the first. In that case, there is no streaming software on the server side - it's just a file that gets sent to a client just like any other file. The bitrate however does tell the client software, like QuickTime player when to start playing the movie (As I alluded to above).
    If you really want to "stream" content - in other words allow people to go to page and start watching then I'm going to suggest you distribute in multiple formats. QuickTime has a number of presets you can use for "streaming", and these are usually small (320*240 or 640*480) videos that are under 1 Mbps (often less than 500 kbps). These files can normally be watched in real time by most clients.
    The other catch with the route you're going is that some computers simply can't handle 720p content that is encoded in h.264 - they just don't have the power. If you look at podcasters many of them have chosen to go multiple formats in part for this reason - they have video embedded on their websites for watching in real time, small iPod formats for lower-power computers and iPods, and HD formats for platforms like the Apple TV that offer the best quality.

  • Required dependencies for Web Dynpro Application accessing KM

    Hi all,
    I need to implement a Web Dynpro application that access km documents (NW 2004s). But i'm having problems to find one required api. I read several tutorials acording to which I need the EP5 user api (com.sap.security.api.ep5.jar).
    The problem is that the application I need to make has to be a development component in NWDI (not a plain proyect).
    What I need to know is which Siftware Component dependencies I should add to my siftware component in order to be able to access the EP5 user api.
    I found the SC required for KM api is KMC-CM, but this doesnot include the EP5 user api.
    Any ideas ?
    Thanks,

  • Short dump when trying to open FPM for Web Dynpro Application

    Hi,
    I am receiving a short dump while trying to open a Web Dynpro Application in FPM.  I go to SE80 and open the Web Dynpro component 'FPM_OIF_COMPONENT'.  I then choose the application '/sapsrm/wda_l_fpm_oif'.  I then click Web Dynpro Application -> Test -> Execute in Administration Mode.  A new IE browser is opened and I then receive a short dump.  The name of the short dump runtime error is 'OBJECTS_OBJREF_NOT_ASSIGNED_NO' and the exception is 'CX_SY_REF_IS_INITIAL'.
    I have not used FPM before.  I would like to use it to remove the 'Close' button from this application.  Do I need to initialize FPM before using it?
    Please help.
    Thanks,

    Hi Chinnu,
    Your understanding is not correct, he is trying to execute the application /sapsrm/wda_l_fpm_oif'.
    Hallo Jeff,
    everyone have suggested lots of possibilities. Nothing works for you. I would suggest the following.
    Go and execute any other FPM application which uses FPM_OIF_COMPONENT,does it work ?
    If it works then you can narrow down that /sapsrm/wda_l_fpm_oif is not working and you can raise a OSS ticket.
    If it is not working then you have to see if you have right BASIS versions to use FPM.

  • Get HTTPS URL for Web dynpro application

    We are using SSL. By default the URL generated for the Web dynpro application is HTTP.
    We went to SICF, and deactivated the HTTP service. That made the URL point to HTTPS.
    But few problems started coming because of it:
    - Our Content server became inaccessible.
    - Every time server is re-started, we need to manually go and de-activate HTTP Service.
    We even tried to set the parameter icm/icm/HTTP/redirect_0. But problem is not solved.
    I know this question is asked before, but every time the answer is to read the help document on ICM.
    What's the correct way for any webdynpro application to point to HTTPS? I don't think de-activating HTTP service is the right way.
    Any suggestions please?
    Thanks in adv.

    Thanks a lot Thomas. I'd ask the Portal Admin to try it out.
    There is another similar problem we are facing: I have embedded Webdynpro in R/3 screen. Then used the cl_gui_wdr_viewer class's load_application method passing HTTPS protocol.
    It returns HTTPS URL only, but is not showing up on users' laptops.
    Earlier we were not passing HTTPS protocol, so generated URL was HTTP, and it was not showing on users' screen (can show in ours). Reason we found out is that users' site has HTTP port blocked. They cannot show any HTTP url.
    So we changed to get HTTPS URL, but that also gives the same problem. It is still trying to get HTTP url.
    Here is the URL that the users got: (when they right click to see the URL generated)
    res://ieframe.dll/dnserrordiagoff_webOC.htm#http://abc.def.jil:8000/sap/public/myssocntl?sap-client=220
    Can give any clues on why this is going wrong? Cannot raise OSS as I know embedding Webdynpro in R/3 is not supported
    Thanks in adv.

  • Best settings for web streaming

    I made an 11 minute film in imovie. I want to put it on my website. I am told that loading it into Quicktime Pro, and then exporting it will give me lots of choices for settings, to optimize the quality and the speed for web viewing. A friend told me to use mp4 at 30 frame at 640 X 480 for acceptable quality. Youtube seems to agree with that. Unfortunately, The resultant quicktime export was a 74 mB file. That seems awfully large for the web. I also tried saving it directly from imovie as an "email", which doesn't allow any tweaking, and that version was 18 mB, and a bit small for web viewing.
    This morning, I've looked through many posts here, but I can't find one place that gives clear opinions for settings for streaming video over the web. I realize there's a lot of choices, so opinions will differ. Nonethless, , but I'd really be happy to have just two or three choices, with all the Quicktime Pro settings spelled out for me. Can someone do that?
    And lastly, what size — both file size and screen size — should I be using for this 11 minute web viewable film?

    I have a similar problem with excessively large files resulting from use of the "export for web" function.
    I have a range of self-contained quicktime movies averaging about 20MB in size. They are all encoded in MPEG4 or H264.
    Exporting for "desktop" results in some files being over 75MB in size.

  • Problems using remote debugging for Web Dynpro applications

    Hello All,
      Have anyone ever encounter the above mentioned problem ? I am not able to step through my codes nor break @ my breakpoints using the debugging features despite many attempts following the tutorial on "Debuggng Web Dynpro applications". The problem always occur when I click on the Run -> Debug -> "Click on Debug". The debug perspective will show the threads running but my application window dows not appear. Should attempts  be made to "Terminate All" threads and relaunch my apllication again, I will get an error message   saying "Deployment of archive file already running : XXX.ear" Then I will need to wait some 15 mnutes or so before I can try again. Any suggestions ? Thank you.
    The status of my J2EE engine is as stated in the tutorial:
    1) State = "Debugging"
    2) Debug Mode = "On"
    3) Restricted Load Balancing = "Yes"
    4) Productive Use = "No"
      I have posted similar queries under "JDI" and "Web AS General" but did not receive and sugestions.

    Kwok Wei

    Hi
    You should Create and Deploy if you want to reflect the code changes that you just did. However if you just want debug to an existing code then you need not Create and Deploy.
    This can also be done as a two step process where you first deploy from NDS and launch Debug without create and deploy.
    Is the issue that after you launch debug that it does not launch the application window.

  • 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):

  • Context root for web Module application (with slash)

    We are on PI 7.31. I am getting URL not found error with web application in certain cases. Initially, i had thought it was not working because of the Slash. Later I realized it was happening with only keyword 'inbound'.
    Edited:
    my alias (context-root) starts with "inbound" and that is the problem.. For me when i try anything other inbound it works..
    For some reason, when I put my context-root as 'inbound' it gives me the message that URL does not work. All other context roots with  and without "/"(slash) works.

    Okay, The URL prefix in the SMICM is generated from the Services/external Alias defined in the SICF. Unfortunately in the new PI 7.31 environment, the URL prefix is stripped down to the first level.
    In our case, we had the URL (/inbound/xxx/yyy) which was SICF service. As a result our URL prefix was stripped to /inbound/. When we developed a java webmodule with URL /inbound/zzzz, it gave service not active error.
    We are creating a message with SAP to see if this will be the standard behavior going forward. Anyone encountered such an issue before?
    Moderators, I guess this question needs to be moved to a different topic thread. Wondering if I should close this thread and open a new one ?

  • 10 Minute video compressed for web streaming help

    Hi, I have to get some 10 minute videos online and I can't seem to get them smaller than 60 MB. Right now they are great quality H.264 files but they are all 111 MB. Does anyone know how to get these files to an acceptable file size for the web?
    I have to keep the size of the video at 570x320.
    Thanks.

    I'd have to agree with Dave on this one. Your movie dimensions are the biggest hang up.
    How about an old Web trick that works nice with H.264 files? Half size.
    Using export via QuickTime at the settings that made the 11MB file but set the dimensions scaled half of your intended size.
    I know. You want a big display in the Web page. Here's how to do it.
    In the html code are special tags used by the QuickTime browser plug-in. One (rarely used) is scale="tofit".
    In the embed tag add scale="tofit" and in the object tag use param name="scale" value="tofit"
    In each (object and embed) tag are dimensions used in the source file. Change these values to your desired size (double them).
    Bingo! Big display of a smaller file sized movie. Your viewers will not know what hit them.
