Embedded flash video freezes after 2 seconds (all browsers, tiger, leopard)

Hi folks. Here's the problem I've been having:

Web-based flash video (youtube and all others) freezes after 2-3 seconds of playback and there is no sound. This doesn't happen always, restarting the browser sometimes helps, but not always. I had this issue in Tiger and I'm now having it in Leopard. I've used Safari and Firefox - both browsers do the same. Tried re-installing the Flash plugin, seemed to solve the problem temporarily but it always comes back again.

I've read somewhere that restarting the "coreaudiod" process solves the problem - it does, but again - only temporarily.

Is anybody else having this issue? I have a MacBook Pro (Core Duo) 2GHz, 2GB RAM, running 10.5.1 and Safari Version 3.0.4 (5523.10).

I haven't been messing around with no Quicktime settings either.

Perhaps it is time you did!

These are the downloads and the settings you need in order to view/hear pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!

It is known to work in the great majority of cases with Safari 3.0.4, QT 7.3 and OS 10.4.11.

Assuming you already run Tiger versions OS 10.4.9 or above (this has not yet been verified with Leopard) and have Quicktime 7.2 or above, and are using Safari 2 or 3, download and install ( or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:

RealPlayer 10 for Mac from http://forms.real.com/real/player/blackjack.html?platform2=Mac%20OS%20X&product= RealPlayer%2010&proc=g3&lang=&show_list=0&src=macjack

Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)

Perian from http://perian.org/

Adobe FlashPlayer from http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash

(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.)

In Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).

In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them).

Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them).

Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz.

Important: Now repair permissions and restart.

The world should now be your oyster!

You should also consider having the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.

Thanks for your reply, very detailed. However, I must say that ALL of the settings and checkboxes (both in Quicktime and Safari preferences) were already set default as mentioned in the instructions. I've already downloaded and installed Perian (though I can't see how Perian can affect playback of web-embedded flash video), the Audio MIDI settings have always been set to 44.1KHz under all options by default and Leopard had the latest version of Flash already installed.

Still, YouTube videos often freeze after 2-3 seconds of playback, despite being loaded (buffered) properly in the video window. The only solution right now is to either restart Safari (or Firefox, which has the same problem) or if that doesn't work - restart the "coreaudiod" process.

Any more ideas?

Hi,

I had the same problem today that flash videos play only for 2 seconds without sound and I figured out the reason for my problem! The problem was that yesterday I paired my computer with my brand new Bluetooth headset. As it's my first wireless headset I didn't know that paired headset has a switch to use headset for sound or not. So my computer refused to play any sound or video when it was set to play sound into paired headset that was unavailable or currently in use with my phone.

To switch your Mac to use headset as sound output, click on Bluetooth icon on a menubar, choose your headset and there you have a menu choice "Use Headset" or "Don't Use Headset". If you have set to use headset but you don't have a headset who currently wants to talk to your computer then this problem occurs.

Thanks, Klaus! I am not looking for a solution by posting here and I'm not planning to post here again.

And you might be correct in your assumption that this problem has no relationship to the same sounding problem posted about the same time on these three forums — one for Linux, one for Windows and one for Mac. But if there is a connection, it might help someone find an answer.

We will see when we start getting some solutions (soon I hope!).

SOLVED!

I was having this two-second playback in silence then freeze problem.

The solution for me was found (rather weirdly) under the Applications>Utilities>Audio Midi Setup settings. I set the "properties for" dropdown to the speakers I was using, then looked at the "Audio Output" settings.

The "Format" was set to 8000.00 Hz, 2ch-24bit. When I changed this to 44100.00Hz 2ch-24bit, all flash played back just fine as before.

This is not the first time the settings in Audio Midi Setup have seemed to change by themselves for me. A few weeks ago they changed to 1ch (mono) output only! This is annoying at it's not an intuitive place to look for a solution.

I hope this has been able to help some of you too.

Mark
