Question

Issue with video playback in Flash Player

I am currently doing some voluntary work for my mom for the local branch of the Alzheimer Foundation. Now I have encoded a video to mpeg4/h.264 and F4V using the Adobe Media Encoder only I am having not much luck to get it successfully played. Now is my question what could I be doing wrong? I already tried to use ActionScript 2 and 3 and disabled GZIP compression on the server and even tried different files like H.264 and F4V.

The strange thing is that the video always work just fine when being tested in Flash CS4 10.2 but when I tried it in the browser it fails. The Test Movie feature of Flash is using the following player version MAC 10,0,12,36. I am using 10,0,32,14 MAC in my Safari browser and their the movie plays fine once the file is fully downloaded (how can I change this?) only when let friends try it out which have version 10,0,32,18 or the same version it doesn't work for them. Also when I am using an older version doesn't seem to work. I thought that H.264 support was added in some version of Flash Player 9. One of the issues which I was getting that the video playback worked lovely in Test Movie with the below listed alzheimer.mp4 url but when testing after the SWF and HTML were uploaded to the webserver it failed to work and I was receiving a FileStructureInvalid error. Now I would expect that the video file would fail in Test Movie too when the video file structure is invalid.

I have tried the following video files both encoded with Adobe Media Encoder:
http://www.letslearn.it/dropbox/alzheimer.mp4
http://www.letslearn.it/dropbox/alzheimer08.f4v

The current player can be found at:

I have attached my As3 version of the Flash file which is normal easy video stuff.

Anyone happen to know what could be the issue here? I am getting desperate!

    FWIW I tried it using the FLVPlayback component in Flash CS4. Using your .f4v file from your site it played in Flash. It did not play in the browser.

    I then copied the .f4v onto my server and renamed it to .mov. That worked for me in the browser as well as in Flash.

    Feel free to try it:

    I then figured that my webserver probably does not understand .f4v. So I added the MIME type video/mp4 for .f4v and tried again:

    http://www.flashcomguru.com/flv/alzheimer08.f4v

    That also works now in the browser. Locally at least. I'm using the latest v10 Player.

    Yes, it has always worked succesfully in the Quicktime player. Maybe I misunderstanding something but I thought H.264 video files support was already added in one of the later v9 player and should work from that version which it doesn't do for me. Only appears to work succesfully in the latest Flash Player version available at Adobe.com.

    Wow. Something is way not right here. Attempting to load your f4v or mp4 in Firefox 3.5 totally crashed Firefox.v


    So next I wonder, what would happen if I try to point FLVPlayback to your videos? (I can't see your attachment for some reason).   Drop a component on the stage, add your F4V as source, test movie, seems to work OK.

    So my next thought is, what's the metadata of the video look like?  Couldn't tell looking at an online tester, and I can't find my local tester just now.

    So some questions:
    a. How big is the source file?
    b. What format is the source in?
    c. What settings are you using to compress in the Media Encoder?
    d. can you upload the video source somewhere that we can download it?
