Seeking in a  Mp3 RTMP audio file

Anyone has already try to seek into a rtmp audio file, to determinate if a file is seekable OSMF 2.0.2494
I use this methode: media.hasTrait( MediaTraitType.SEEK ), but it always return false.
Any idea ? Thank

I'm streaming it, and I've figured out how to make the video jump to a
specific point, it had to do with the fact that .FLV files take the
offset in bytes, and .MP4 files take the offset in seconds
I am not sure what you mean by that. Method seek() accepts time and is executed so that closest video KEY frame (I-frame) is hit. So, I am not sure that encoding makes any difference.
Here is a quote from documentation of seek():
Seeks the keyframe (also called an I-frame in the video industry)
closest to
  the specified location. The keyframe is placed at an offset, in
seconds, from
  the beginning of the stream.
WIth that said, chances are that your video has very big gaps between keyframes. For instance, if the gap is 10 seconds and you try to seek to second 4 it may throw playback to 0 as the closest keyframe.

  • IWeb and MP3 or audio files

    Just got a Mac and looking at the information for iWeb, it talks about text and video, but nothing about audio files, like MP3.
    I assume I can upload MP3 files (my own) using iWeb, but just wanted to confirm that before I purchased it. I have my own web page now and would like to redo it with iWeb, but obviously I want to include my original MP3 files in the web page for others to hear and download.
    Thanks

    iWeb writes page code that will play your MP3 files using the QuickTime browser plug-in.
    If you need to use another plug-in or player you'll need to use the special "snippet" code feature.

  • Audio File Not Valid! on Zen Sleek Ph

    Hello!
    I've had a Zen SleekPhoto for a few days, and was initially delighted, until I realized that a significant part of my music collection will not transfer to the player.
    I have many mp3 files which result in this message from Zen Sleek Photo Media Explorer when I try to send them to the player:
    "Cannot Copy 'somefile.mp3': the audio file is not valid or not recognized. Do you want to skip this file?"
    When I try to send the files using WinAmp, it just skips them without informing me.
    What does this mean
    !!! These are all mp3 files with ID3 tags filled in. They play just fine on WinAmp, iTunes, and Windows Media Player. I'm sorry to say that I cannot give encoding details about all of them, as I have neraly a decade worth of encoding different disks on different computers at different times represented here.
    Is there some type of mp3 this player will not play? Most are 28K mp3s.
    Firmware .0.0
    Windows XP system.
    If I cannot get this player to play half my collection of music, I will have to return it to the store, which is a shame, as it seemed so promising. I would be grateful for any help.
    A friend who got a Zen Sleek Photo a few days ago is also having the same problem on a different computer, with a different music collection entirely.Message Edited by celticchrys on 05-25-2006 0:45 PM

    cheers for that,I didnt mean the clicking on the touch pad but the clicking coming from inside the player :smileytongue:I have found some other threads about it and it does seem to be normal...which is?good ...cheers for the replies

  • Can i convert AIFF audio file into an MP3 file please?

    Can i convert AIFF audio file into an MP3 file please? I will be doing this on an imac 2008 model. thank you for help!

    Since this is the Logic forum and you may be working in Logic, you dont even need iTunes. To convert Aiff to MP3:
    1 - Go to the Bin>Audio Files
    2 - Select the Audio File you want to convert ( and not a region or edit of it)
    3 - Go to Audio File next to the Link icon ( Audio - Edit - View ) and down the menu to Copy/Convert.. gives lots of options

  • How do I listen to mp3 audio files on my iPhone 4s?

    I have recently purchased and downloaded some mp3 audio files onto my personal computer.  I was able to transfer them to my itunes library.  I now want to listen to them on my iPhone 4s.  How do i do this?  If I go to the itunes store application, i can see all of my "purchases", and I can easily download those to my iphone.  But these particular audio files were not purchased from itunes.  So how do I get them to my iphone?  Thank you!!

    I also have purchased and downloaded an mp3 audio file (not from itunes) onto my macbook air.  I was able to transfer it to my itunes library.  I now want to listen to it on my iphone 4s.  How do I do this?  If i go to the itunes store application, i can see  my "purchase"  .   I emailed the mp3 (it went to a downloader automatically).  I couldn't open it in email to listen to it on my iphone 4s.  So I purchased  idownloader pro".  still cannot listen to them on my phone.  Isn't there a way to transfer them without physically connecting the mac to my iphone?  afraid to do this as I screwed up my files, etc doing this in the past!! Any suggestions???    Thank you!!

  • Compress audio file to mp3 or aiff of 5 MB?

    Hello,
    Does anyone know if I cam compress an audio file on GarageBand for the iPad 2? I'd like to take a file 30 minutes in length and be able to email it, so I need to compress it to 5 MB or less.

    only thing I can think of is "share with iTunes" and then once the file is in iTunes, compress it again there, by going to iTunes -> preferences and on the general tab, about 3/4 of the way down, click Import Settings and then set your settings to MP3 and then choose custom from the settings drop down and then choose a really low kbps bit rate. You may have to experiment, I haven't had coffee and can't do the math right now to suggest a bit rate for a 30 minute file becoming a 5MB MP3. Good luck!

  • Premiere Pro CC won't import ANY audio file, be it an mp3 or part of an mp4 video (or other formats)

    Any audio or video file I drop in to premiere will almost immediately pop up with the window
    Audio Conforming Error
    Error compiling movie.
    Unknown error.
    When I check the error/event log (little red X in the bottom corner) that window says:
    "11/21/14 09:47:28  A disk error occurred while attempting to access the following files:
    \\ipsse01\home$\myusername\AppData\Roaming\Adobe\Common\Media Cache Files\filename.mp3 44100.cfa"
    (The actual file is on my desktop)
    This happens with everything, even the stock audio files Windows comes with in the "Sample Music" folder, I tried those too to no avail.
    I'm at a complete loss. I'm new to premiere pro but these are generic file formats so I don't think the issue is with the file. I haven't tried to reinstall because I'd have to go to our one network administrator/IT person (who also is the accountant for the company) so she can enter the admin user name/password in the pop up box, and she's often so busy. I'm trying to avoid bugging her if I don't need to (which unfortunately I tend to still have to do a lot)
    For reference I'm running Win7 Professional 64-bit, 8GB RAM, and an i7-4610M CPU @ 3.00 GHz.

    Thanks for responding, but I work for a very small company and since I'm the only one who needs CC, I have the personal version installed.
    Also this appears to be a blanket issue with all audio and video file formats, thus not likely a codec issue since the files I've tried so far should be covered by premiere's compatibility, the even play in windows media player with no issue.
    Video itself plays fine, but any audio attached to a video, or just plain audio files will not import no matter what I try.
    Sorry my info didn't help.
    Two things to try.
    Create a brand new project and test if you can import the problematic files.
    If that does not work, change the name of the folder that contains your media files. Then try to import.
    Let us know what happens.
    Thanks,

  • Assistance needed in trying to import MP3 audio file into Slide Show

    I get the following message when trying to import an MP3 audio file into a slideshow in Organizer 9 "The selected file can not be played because your system does not have the required compressor/decompressor(codec) installed. I am pulling the file from my Itunes folder and I have not had problems with any other file I have downloaded from itunes and changed to an MP3 format.  Does anyone have any ideas?  I really want to use this song in a slideshow for my parents 50th Anniversary.

    Best GUESS is that DRM is getting in the way of the file being used outside of iTunes (DRM = Digital Rights Mgmt = Copy Protection)

  • Trying to import .mov audio file and burn as MP3

    Can someone point me to a thread, or be kind enough to post answer, about how I might successfully import a .mov audio file and wind up burning it as an MP3. I've been dinking around with this for too long. I can import it and end up with it in the format: MPEG-1, Layer 3. But when I burn it to CD and play it on a Sony boom box, I hear nothing. I tried playing it in another iMac and hear nothing.
    Thanks.

    I was hoping someone in this forum could point me in the right direction to a web site that is designed specifically for Garage Band users that need sound effects.
    Check out:
    http://www.macjams.com/
    http://www.thegaragedoor.com/
    These both are GarageBand-oriented.
    Also, check out:

  • Why is the audio file stop playing midway through a .mp3 file in Firefox and not in the IE browser ?

    I added an audio file on to my website, http://www.widescreenonlinereview.com/COMIC-REVIEWS.html. However, the mp3 file stop midway though the song, but the .mp3 file plays completely in the IE Browser.
    I tried update Firefox, but I lost some major add-on, which me caused to return to my present Firefox browser, and the .mp3 file still would not play completely in the updates browser either.

    Hello,
    '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
    ''(If you're not using it, switch to the Default theme.)''
    * You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
    ''Once you get the pop-up, just select "'Start in Safe Mode"''
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    ''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
    Thank you.

  • Spltting an MP3 song or other audio files. PLEASE HELP!

    Hi, guys. I dont even know if I am discussing this under the right category but I hope someone can help. I have a Mac Pro, which I just acquired. I have been used to Window PCs all my life. I am trying to see if there is a way I can split a large audio file (MP3 song) into a smaller clip on the Mac. I don't even mind if this means I have to download an additional program. I am trying to use an audio track I already converted into an MP3 version as a ring tone on my phone. But I don't like the way the song starts from the beginning. I am trying to create a 1-minute audio clip out of the long track and use that. I'll appreciate all the advice I can get.

    hey there Dr. Tee & welcome to Discussions.
    you could try to do this w/ GarageBand. open GB, import or drag in the file, cut out the parts you don't want, from Toolbar menu, "Share" ringtone to iTunes.
    good luck.

  • How do I convert qcp audio file (from cell phone) to mp3 file?

    I moved a recorded cell phone conversation from my phone to my computer. The file is 982498.qcp and iTunes, VLC, Quicktime, or Windows Media Player will not play it. iSoundFile is an application that can convert many different audio files to many other different audio file formats. It does not work with qcp files.
    How do I play this qcp file? Or, How do I convert this qcp file to mp3 or something playable?
    The phone manual says nothing about it (its an LG 8600).

    I've tried it 3 times. It says "Error while converting file." Thanks though, it looks like the perfect site for this function, just wish it worked.

  • How to Convert iTunes Songs (Apple lossless audio file) to a MP3 for E-mail

    How to Convert iTunes Songs (Apple lossless audio file) to a MP3 for E-mail?
    My computer is Windows 7 and my Itunes software version is 1.0.2
    Many thanks in advance...

    iTunes 1.0.2 is +at least+ eight years old.
    The current version is 9.2, and it's free.
    If that was a typo, and you're using something more current:
    In the iTunes preferences, change the import settings to mp3.
    Then select the songs you wish to convert.
    From the "Advanced" menu, choose "Create mp3 version".
    When done, change the import settings back to Apple Lossless.
    That's it.
    BTW, this is the Logic Pro forum, which has absolutely nothing to do with iTunes.
