Hi all ,anyone knows some usefual Codecs for H.264 live video/audio

I'm headache about the JMF codecs ,they are too few ,and seems inefficiency, anyone knows pure java codecs for H.264 or MPEG4 ?And I think it's better a open source one ,do my thanks , guys!

Here are some basics....
FMLE creates RTMP protocol streams that PCs and Macs watch with Flash players.   iOS devices don't understand RTMP (Flash), only HLS delivery of 10 second chuncks of downloaded video playback.  Both systems understand H.264 video, but iOS wants to see AAC audio not MP3.
You didn't state how you are live streaming, meaning what bandwidth delivery service you are using.  Live streaming only via RTMP won't get you to successful iPad and iPhone HTTP Live Stream.  On-demand delivery to iOS devices normally requires .mp4 video files to be hosted, which Macs and PCs also understand via RTMP delivery.   But unless your delivery service can convert .f4v or .flv files to .mp4 on the fly there is no easy way to to get to iOS via the direct file output of FMLE as of today.   Sometimes we upload live encoded project files to our www.Wistia.com account for PC, Mac and iOS delivery.  This is a YouTube / Vimeo paid type hosting service for on-demand only.
Some commercial CDNs (Content Delivery Networks) today allow an inbound live RTMP into their system using FMLE.  Then they re-mux that RTMP stream into HLS delivery for iOS.  Some work well using the native MP3 audio codec (Internap), but most require FMLE to have the AAC audio codec installed from Main Concept for $200.  Or people use Wirecast from Telestream which is $500 per license to be able to run two instances on that one license.
In my 15 years of being a big commercial webcaster here in Silcion Valley, I have yet to find the perfect simple and easy and affordable RTMP to HLS live and on-demand delivery system.  We currently do it different ways with multiple providers depending on the job.  More offerings are coming out now and we try them all as they come down the pike.

  • Does anyone know a work around for cs6 not supporting video on windows 8.1? Can i use another program to open it and get it into photoshop?

    Thanks in advance.

    Try downloading and using VLC. It is a very popular media player that plays just about every file format out there. That way you would not need to convert it.

    This is the top story at this writing at AppleInsider:
    Like the updated mid-2014 13-inch MacBook Pro with Retina display, Apple's latest 15-inch notebook brings slightly speedier Intel processors. But with memory, graphics and design all carried over from last year, the most substantial change is a $100 price cut.

  • Does anyone know a adequate program for a cleaning MacBookPro

    Hi !
    I want to know ... does anyone know a adequate program for a cleaning MacBook Pro?
    Something really affective and appropriate for MacBokPro

    OnyX is popular for cleaning up your system.  You typically should not experience performance degradation over time however.  If your system is not performing well, you should track down the cause.  If you just want to keep things tidy and clean up some space OnyX is a good choice.  You can download it for free directly from Apple:

  • Does anyone know the default size for 24 in. imac display?

    I inadverently changed the display size on my 24 inch imac. The font in the toolbar at the top of the desktop is larger than I want. Also, when I open windows in different applications, they open larger than the display and have to be downsized in order to see the entire window.
    Does anyone know the default size for this display? Or is there a different way to fix my issues?
    thanks in advance.

    Hi Napamike2: The default setting for the 24" is 1920X1200. If that doesn't get you back to the proper display, maybe you have accidentally activated "Zoom". To check go to System Preferences, Universal Access. Check that Zoom is turned off.

  • Outlook 2007 doesn't show icloud service running.  Does anyone know what the dll for this service is so it can be manually added to outlook?

    Outlook 2007 doesn't show the icloud service running in Windows 7 within outlook.  Does anyone know what the dll for this service is so it can be manually added to outlook?   I've installed the icloud control panel app and set it up to synch everything, but after initially downloading my icloud calendar, it won't process any calendar updates (new entries made on either iphone 4 on ios 5 or outlook). 
    So since the control panel installed, but the service doesn't show running in outlooks "trust center" add-ins list, anyone know the actual dll file it would point to so I can see if I can add it the hard way?

    I had the same issue and figured it out.  First you have to start Outook as administrator.  To do this, shift and right-click on outlook and click run as administrator.  Next you need to enable Hard-disabled add-ins:
    Hard-Disabled Add-Ins
    Hard disabling can occur when an add-in causes the application to close unexpectedly. It might also occur on your development computer if you stop the debugger while the Startup event handler in your add-in is executing.
    To re-enable an add-in
    In the application, click the File tab. 
    Click the ApplicationName Options button.
    In the categories pane, click Add-ins.
    In the details pane, verify that the add-in appears in the Disabled Application Add-ins list.  The Name column specifies the name of the assembly, and the Location column specifies the full path of the application manifest.
    In the Manage box, click Disabled Items, and then click Go.
    Select the add-in and click Enable.
    Click Close.
    Then you need to activate it. 
    To re-enable an add-in
    In the application, click the File tab.
    Click the ApplicationName Options button.
    In the categories pane, click Add-ins.
    In the details pane, verify that the add-in appears in the Inactive Application Add-ins list.  The Name column specifies the name of the assembly, and the Location column specifies the full path of the application manifest.
    In the Manage box, click COM Add-ins, and then click Go.
    In the COM Add-Ins dialog box, select the check box next to the disabled add-in.
    Click OK.

    Mac users using Word 2004 who receive a Word 2008 for Mac, (or Word 2007 for Windows) document, will not be albe to read this without having the Open XML Converter installed, which can be downloaded from Microsoft.
    Go to this page:
    http://www.microsoft.com/mac/downloads.mspx
    and click on the right under Most Popular, 'Open XML File Format Converter for Mac 1.0.2'
    This opens a window at the bottom of the page. Scroll that to the bottom and click on English.dmg, and it will download for you as a disk image, which can be installed in the usual way.
    After installation you can open and read .xml formatted Word 2008 documents in Word 2004.
    Update: This link  http://support.microsoft.com/kb/976831  takes you to a newer version 1.1.3 (released Nov 10, 2009).

  • Does anyone know a mouse solution for someone having parkinson disease

    Does anyone know a mouse solution for someone having parkinson disease?

    Thanks Les.
    FX has just provided an update that is suppose to fix this issue but the update fails to download...I guess I'll just wait a couple of hours until they fix it.
    In the meantime I turned off the plugin and it's now working. At the moment I just need to draw in illustrator so fonts aren't a worry for now.
    I appreciate your help

  • Does anyone know if the beta for iMessage is down

    does anyone know if the beta for iMessage is down

    Hi,
    Can I check the following ?
    You have people in your Address Book with iPhone Numbers and/or Apple IDs listed ?
    In Messages beta you are starting with a "New Message" either from the File Menu or the icon on the top of Messages main window ?
    With a "New Message" showing you are using the blue icon that appears top right
    In this Menu drop down you are selecting Contacts and then a person from the list ?
    You are selecting this person on their iPhone or Apple ID that you know they use in iMessages ?
    You are saying that their name goes red when it is in the "To" Spot.
    Pic of a Name that has gone Blue
    Uploaded with Skitch!
    Messages may or may not have the little Speech bubble next to a Contact point as it can depend where you are in your Sync process and which Contacts you have already had.
    If the contact goes Red it could be that an email you are using is NOT an Apple ID, or it has not been linked to iMessages yet.
    It could also be that they are out of range in one form or another.
    Messages can't tell which Numbers are iPhone Numbers until the other person has Registered/Linked it to thier Apple ID or you have contacted them.
    I have had issues where In my Mac's contact List I keep only the "Local" phone number where Messages Needs the +(Country code)  bit as well.

  • Does anyone know why- when I iport a one minute video project into Final Cut X from I Movie the resolution that looked alright in IMovie full screen becomes worst in final cut, full screen...but clear when it is in still position?

    Does anyone know why- when I import a one minute video project into Final Cut X from I Movie the resolution that looked alright full screen in I Movie instantly becomes worst on full screen in Final Cut X...but clear again when I stop it to still position?

    I'm new to video editing but I think I recall seeing an option in FCPX which lets you choose the video quality for the preview window. I think the window reduces the quality when playing back for performance reasons and so perhaps that is why it seems to have less quality when moved over to FCPX? Just a possibility, I'm sure one of the more experienced users can confirm or deny this theory.

  • Anyone know a good place for Sony camcorder batteries?

    This is a bit off-topic for this forum, but does anyone know a good online store where I can order spare batteries for a Sony HDR-SR5 camcorder? One battery isn't going to cut it. I know some of you on this post have an SR5.
    The Sony store is waaaay too expensive, and all the off-brand online stores seem too dogdy.
    Thanks,
    Otto

    I wouldn't expect a big drop too soon. That's a lot of RAM density on a small board. Unless there's a major increase in demand I wouldn't expect much of a drop in price.
    No doubt there may be cheaper prices than Datamem's. Although their prices are usually competitive, they are not always the cheapest. But they do offer good service, fast delivery, have a good return policy, and experience with Macs. My recommendation is based on a 10 year history with them which has been 100 percent satisfactory.
    But $500 for a marginal 1 GB of RAM is a lot. I'm not convinced it's enough to warrant going from 2 GBs to 3 GBs. I have 2 GBs in mine and it seems perfectly fine for my needs.

  • Anyone know a fast converter for moving my movies into itunes?

    I just got an apple tv2, i have airvideo on my IP4 that works but i want to stream movies from my PC directly to ATV2. Problem is that i have like 300 movies that aren't converted for itunes... Anyone know a good/fast converter? Would be nice if it could automatically add the file into my itunes and even delete the old file after its done conversion. OR even better if theres a way without conversion at all =) thx

    You definitely need them in iTunes and they also have to be compatible with ATV to stream from PC
    http://www.apple.com/appletv/specs.html
    In terms of converters there's handbrake, mpeg streamclip, visual hub..those are ones that I have found to be of good quality.
