I'm also using Google Chrome with the latest non-pepperflash plugin enabled. I disable pepperflash because it makes audio and video of out sync.
Pretty much every day either two things happen. One, chrome can freak out and cause my laptop to freeze for 3-5 seconds and then go back to normal, or flash player can cause Chrome to go unresponsive, and then shockwave flash player will crash when it lets me choose to end it. It seems like Flash player these days is terrible. On my older desktop with a Core 2 Duo, pepper flash causes videos to be out of sync in a very obvious fashion. On a Core 2 Duo 3.0GHz, are you kidding me? 1080p videos used to play very smoothly, and now Flash player is total crap wth Chrome on that computer. And now on my i7 processor I am getting crashes and freezes? I really hope that Google gets HTML5 video nailed, because I will stop using flash once HTML5 works well and is used more by websites.
I don't know what platform Adobe is developing for. Flash these days works like crap on single core processors, but Flash 10 and under works fine still, Flash these days works like crap on dual core processors in many cases, and now the power of an i7 isn't enough to prevent crashes. What are they developing for? PowerPCs? Are they even testing Flash on more than one computer? Seriously, way to give away the sign that you're ready for HTML5 to take over. Stop trying to put in bullcrap features and make the CORE PROGRAM work in a stable manner. I'd rather have a stable Flash player that plays videos well than an unstable Flash player that has whatever special 3D optimization API OpenGL blah blah blah. Why does Flash 9 work better than Flash 12 for people with single cores? Why are we getting way more crashes than we used to?
The primary difference between Flash Player 10 and 11.x is that we're leveraging your system's graphics and audio hardware acceleration (on windows), where we were previous using the general-purpose CPU for video decoding, and the old Windows WavAudio APIs instead of the modern CoreAudio subsytem (which leverages your audio hardware's acceleration capabilities).
The first step is to work through the video troubleshooting guide for your operating system, here:
When reporting issues with video or audio, it's also helpful to get your system hardware and driver details. Instructions for finding this information can be found here:
Finally, sometimes video and audio problems are caused at a lower level and not directly related to Flash Player. I recommend trying both of the links below to see how they perform. If the problem exists with both, then Flash Player is most likely not the culprit as the HTML5 video link does not use Flash Player when playing. You can verify this by right clicking the HTML5 video and looking for the words "About HTML5" at the bottom of the menu.
