Getting FMS to broadcast a media file being read via a named pipe.

I know you can broadcast partial AVI videos due to it's format. What I want to do, is feed an avi file to fms which is being generated by software on the local machine. If I create a named-pipe(on windows), will I be able to feed an avi file to fms while it's being read?

Thanks Balusc!!
I have made use of your code to display PDF files in an IFRAME tag too!!! I just dint believe that this would be possible. Please just take a look at my JSP page.

  • Cant get quicktime to always open media files

    I'm a very new Mac OS user so forgive me if this has been answered elsewhere or I'm just dumb and don't know what I'm doing.
    I'm trying to get some media files (WAV for example) to always open with QuickTime instead of iTunes. When I do Open With, Other, and select QuickTime and check Always Open With, it only changes that files association, not every WAV file.
    When I right click and do Get Info, the Change All button never un-grays. As before, I can only change the association of that one file.
    The QuickTime panel is set properly but I believe that only refers to the plugin. I've looked thru iTunes but can only find a button to make it the default player, not a way to un-make it the default.
    Any suggestions??
    Zach

    Hello Zach:
    Rather than me put you through hoops, I suggest you post in the Quicktime forum:
    http://discussions.apple.com/category.jspa?categoryID=122
    There are people there that are expert (I am not one) with the QT application.
    Barry
    P.S. There are no dumb questions, but many dumb answers.

  • Getting format/codec info from media file.

    Hi all,
    Using the QuickTime SDK I see how can retrieve metadata about the content of a media file like title, author, etc. But I can't see how to get metadata about the data itself like format, codec, bitrate, framerate, etc.
    I've used code from the QTMetadata example to get me started with metadata like so:
    while(QTMetaDataGetNextItem(/*... */)){
    but as mentioned, it seems one can only get content metadata.
    How should I go about retrieving metadata about the data?
    Thanks.

    Ok, well, I've found ExtAudioFileGetProperty() from the AudioToolbox framework. It works but I'd still be looking for something similar from the QuickTime framework so if anybody has got a hint, I'd still appreciate it. (Not to mention that thre's doesn't appear to be an equivalent framework for video files, e.g. VideoToolbox, which I need as well).

    I upgraded from my
    mac pro power pc, G5 ( running leopard 10.5.8 combo update)
    to
    an Intel iMac Running Lion,
    after failing to move my data with migration assist, then target disk mode - i phoned Apple - which said id need an external drive. 
    I used time machine to copy my user data from my G5.  However Lion will not recognize the external drive.
    Ive been at this for a few days and anxious to expedite the move, mostly photos, and media files.
    If Re-formatting is the only way.....is there a way to  do so without another day of re-copying by firewire.
    The external drive is a Ciel Lx , recomended to me by apple.
    Any one else making the move from power to intel? Havent found much posted recently.

    So we know more about it...

  • Unable to access media files on network via wirele...

    Up until a month ago was able to access media files through wireless, Os is wins 7, HomeHub 2. the curious thing is no problem accessing internet wirelessly, Have reconfigured Homegroup network, changed WEP key, channel no,reset connected devises then for a couple of minutes I actually access my media files then nothing , and nothing since. unable to access Hub manager from desktop icon or internet browser now. One thing that might be pertinent is that my father has  just had YouView installed around the time the problem started. Contacted the call centre for help they came back informing me that you cannot share files through a BT Hub ! last resort sent an email . Anyone out there can throw me a line I'd much appreciate it

    Try a factory reset of the homehub by pressing a pin into the recess button on the rear for about 20 seconds. This will put your wireless passkey which is on the homehub label so you will need to either reconnect your devices to the default wireless passkey or change it back to what you had.

  • Writing to file being read

    Is it possible to write to the same file that is being read in java. For instance I am opening a file and padding every line so that ever line contains 100 characters. After I pad each line can I write it back to the source file or would I need to create a temporary file, delete the original, and rename the temporay file?
    Nathan

    would I need to create a
    temporary file, delete the original, and rename the
    temporay file?That would be it, yes.
    Consider this: you read (say) bytes 1 to 79 from the file, that being the first line. You pad that to 100 bytes and write those back. Then you want to read the next line, which starts at byte 80. That is, it USED TO start at byte 80 until you overwrote it. Now it's garbage.

  • Are my media files being compressed when sending From iPhone 4 to Apple TV?

    I noticed that pictures and videos taken on my iPhone look especially grainy and washed out on my TV when sending to Apple TV via Airplay. It's a 720p set and iPhone 4 records video at 720p so shouldn't the video look at least close to as clear? I understand that it is a larger screen but the difference is substantial. How about audio?
    P.S. I am working over WiFi if that makes a difference.

    no compression takes place

    Sorry about the size of this but I think I should supply all the code to help you..
    A text file contains 11 lines like this (separated by tabs)

  • Trimmed Quicktime Time code Media Files not reading correctly in CS5+ (works in CS4).

    I'm using Prores footage with metadata Timecode inserted into the Quicktime file.  Then I edit the Quicktime file, click "Save" and then import the trimmed file into APP CS4.  CS4 recognizes the edited clip and displays the timecode correctly (adhearing to the trims made on the file with Quicktime).
    BUT, in CS5, when I use the SAME clips, the timecode displays what the untrimmed timecode on the trimmed image.  So now, my timecode is OFF. 
    Really want to figure out how to fix this.  Does CS6 fix this issue?  Is there a preference or custom setting I need to select in order to have CS5 adhere to the metadata stored in the Quicktime file's timcode information?
    Any help would be greatly appreciated!

    There is a difference between Save and Save As in QuickTime Player. When you Save after trimming, the trimmed data remains in the file and takes up the same amount of space as before. When you Save As, the trimmed data is not included and you end up with a smaller file.
    I don't know why CS5 is behaving differently but it's more efficient to Save As and it will solve the CS5 problem too.

  • How to isolate media files in Applications from video uploaders within FMS

    Hello,
    We have linux-centos with FMS 3.5.2, apache is on another server.
    We host media files within applications folders.
    The media files are uploaded via ssh by different users, each one populating her own my_app/streams.
    the problem:
    We do not want the users to be able to see/download one another files while connected via ssh.
    This is difficult because of the user/group needed by FMS.
    We tried several hours changing groups/users without finding a solution.
    Either FMS cannot stream or a user can see/download elsewhere than in her my_app/stream
    (to explain a bit better, I hope, a view of a situation where it does stream, but also leave media files accessible to useradm2)
    FMS is run by fmsuser:fmsgrp
    user1 uid:gid is usr1adm:fmsgrp
    user2 usi:gig is usr2adm:fmsgrp
    [root@my_serv ~]# tree -gup /home/sanmultimedia/applications/testaccess/

    VOD changes won't help him, he said outside the applications
    folder. According to adobe any new vod folders must be in the
    applications folder, hence virtually worthless for most purposes. A
    better question may be, how do you specify a folder on a different
    local hard drive. I wish adobe wouldn't make it so complicated, it
    should be a really simple matter.

  • Media files on my iPod touch are categorized as other and I can't use them

    I connect my iPod touch to iTunes on my cousins computer and all my media files were tranfered to other. They still take up space on the iPod but there not where they are supposed to be. I think something like this happened when I had my iPod video but I fixed it easily by opening the iPod files with mycomputer and finding where they were I could right the wrong....however, my iPod touch does not appear in mycomputer wen I connect it but on my laptop wen I open mycomputer it appears as a camera and I cannot do anything with that. Is this normal....should my iPod appear in mycomputer......and how do I fix the problem with my media files being categorized as other.
    P.S. If I add new media files they go where they are supposed to. I could restore my iPod and start over but I don't have backups so I want to get them back in there proper place

    I really don't want to do that......is there anything the people at the apple store can do?
    Also.....I was was having a problem viewing videos. The videos showed as bright colors i.e hilighter yellow and pink and it was distorted. Even youtube. I restored the settings and it stopped....did this happen to any1 else and is it something I should be worried about although its gone?

  • Using Windows 8 64 bit Premiere Elements 12 , motion tracker gives me the folloing error; The media file seems to have an invalid entry in the catalog, please rename it for use.

    I'm trying to put a graphic over an object, but I keep getting this error message; The media file seems to have an invalid entry in the catalog, please rename it for use.

    Lonesomeless
    Thanks for the reply.
    I checked the link that I posted back in post 3 of your thread. It is working with at least Firefox and Chrome.
    ATR Premiere Elements Troubleshooting: PE12: Motion Tracking/What To Use To Track Object?
    What browser are you using?
    The blog post contains significant information related to Premiere Elements 12 Motion Tracking. But, if you cannot access it for some reason, then we will need to troubleshoot via communications in the thread.
    SG has asked if you are able to create Motion Tracking effect using one of the graphics included with the program. We will watch for your response to him on that question. Please include in your message to him whether you can obtain your file to track the object using Organizer Tab or Project Assets routes as well as Graphics Tab.
    The following is an excerpt from the blog post referenced....
    SOLUTION
    Various tutorials and online comments have pointed to places other than Graphics Tab where objects can be selected and used to track the moving object in the video when the Motion Tracking workspace is opened in the Expert or Quick workspace.
    Organizer Tab, Expert or Quick workspace to access Elements Organizer 12. Cascade Windows and drag a video or photo from Elements Organizer into the yellow track box of Motion Tracking workspace.
    Project Assets, Expert workspace. Drag text, video, or photos from opened Project Assets into the yellow track box of Motion Tracking workspace.
    Graphics Tab, Expert or Quick workspace. Create a png file (graphic) or prtl file (text) and place it in Clip Arts in the Program Files of the program to have a permanent resource. Then from Graphics Tab, drag the newly created graphic or text object into yellow track box of Motion Tracking workspace.
    Thanks.
