Anything and everything.

I wrote up a long post about my media playback problems, thought I’d fixed it, played two files without a problem, hit post and went to watch a few videos. The problem returned, my frustration trebled.
I thought I had fixed it by installing ffdshow-tryouts and Haali’s splitter. I was mistaken.
In the end, unplugging the television and running the single LED display has completely eliminated all sync and frame dropping problems. I just played back a 22 minute video with not a single dropped frame and Sync Offsets of 0 throughout according to MPC-HC’s statistics.
I don’t know if the videocard just cannot handle both displays, or if there’s some trickery I need to try to make it perform better, but needless to say it is bloody frustrating.
One of the things I really dislike about reinstalling Windows, whether from need or just masochism, is that I run in to all sorts of problems that I’ve never seen before. For example, my D-Link DWA-552’s poor performance. That’s half the reason I bother with this blog. I’ve a terrible memory, so keeping track of the issues and my attempts at fixing them just seems like a Good Idea. And if I can point someone else in the right direction, even better.
After fixing my audio problems I had hoped that my media playback difficulties would be resolved as well, but this was not to be.
I run a dual display setup off of my single EVGA nVidia GeForce 460 GTX. DVI-1 connects to a 24″ Samsung SyncMaster BX2431 LED display via a DVI-to-HDMI cable, while the HDMI connection is plugged in to a 40″ Samsung LN40D630 LCD television. The TV’s audio is plugged in to my desktop’s 2.1 speaker setup via a 3.5mm TRS plug for those moments when I need a bit more boom.
Aside from the obvious hardware changes of a new processor, motherboard (and the differences in onboard hardware), and the recently upgraded wireless card, the only other big change is upgrading Windows 7 x64 to Service Pack 1.
My preferred media player, Media Player Classic – Home Cinema has suffered terribly from dropped video frames and the audio has refused to stay in sync, growing progressively worse as the video plays on. VLC media player fares a little better, but while playing it averages 35-50% dropped frames according to its playback statistics. Sometimes it’s not quite as noticeable, but being near sighted has made me annoyingly sensitive to things like frame skipping and tearing (and dead/stuck pixels in a display, to my everlasting irritation).
I’ve tried everything I can think of, upgrading/downgrading/upgrading my audio drivers for my motherboard’s built-in Realtek HDAudio hardware, using the latest beta nVidia driver, and disabling Aero in favour of the Windows Classic appearance. I’ve twiddled services, changed audio output settings, all to no avail.
The last step I tried, and the one that seems to have finally prevailed, was to install Haali Media Splitter and a recent SVN build of ffdshow-tryouts by clsid. I set the splitter to handle everything it could, and set ffdshow to only allow whitelisted programs due to incompatibilities with certain games that I happen to play (such as Fallout 3).
MPC-HC needed a bit more tweaking to make it use ffdshow and mkvsplitter.
I think I’ve got it right, although I’m pretty clueless when it comes to the gory details of media playback on Windows. Either way, this appears to work and MPC-HC claims it’s using ffdshow, with the notification area icons backing it up.
So far so good. I’ve watched two videos that were horrendous, exhibiting the sync and frame dropping issues as soon as playback began. Using the external filters appears to have cleared up my issues completely. I haven’t looked in to enabling DXVA in ffdshow for acceleration yet, I’m just happy I can watch videos flawlessly now.
Well, it looks like I spoke too soon, the sync problems are back with a vengeance.
This is bloody annoying.
Oh, and happy 36th birthday to me.
Starting a VirtualBox virtual machine results in a warning popup:
This is because Windows/the audio driver has disconnected the devices due to nothing being plugged in to the relevant ports. Modern audio hardware has a feature called jack sensing, and can disable the respective devices when there’s nothing to receive input from or send input to.
Plugging my headset/mic combo into the front-panel audio connectors results in the microphone recording source being enabled.
If you want these sources to be available to your VM, ensure they’re plugged in before starting it.
A while back (almost a year, wow), I had problems with Windows 7 “locking” executable files, preventing their deletion and overwriting. Recently I’ve run in to problems again, specifically when running NASM’s configure script, though I’d imagine it can happen any time.
I believe the Application Experience service is acting up again. Going through the Windows Event Viewer, there are multiple entries in the System log indicating that the Application Experience service is being started and, approximately 45 seconds later, stopping. The times coincide with my attempts to run the configure script. Coincidentally, my display driver just crashed. Sometimes I really hate computers.
Anyway, we’ve had Windows Vista for five years last month (!), and Windows 7 for just over two years. I don’t, to my knowledge, run any software that isn’t Windows 7 safe, so disabling the Application Experience service once and for all shouldn’t be an issue at this point. The problem is that just disabling the service causes problems as mentioned in my previous post on the issue.
A bit more digging around brought me to Black Viper’s entry on the service in question, complete with a description of how to turn off this “feature” entirely. This needs to be done via the Local Group Policy Editor, a feature which may not be available on all versions of Windows.
Using the Run dialog (WinKey+R), run “gpedit.msc”. Navigate to Local Computer Policy->Computer Configuration->Administrative Templates->Windows Components->Application Compatibility. The two settings we’re interested in are “Turn off Application Compatibility Engine” and “Turn off Program Compatibility Assistant Engine”.
All that’s left is to set the Application Experience service to disabled and reboot.
There’s a bevy of additional “tweaks” that can be made with the Policy Editor; Google can be your friend. Double check before you enable/disable anything! Also, if you do this, be aware of what you’re installing – make sure you use software that is known to work properly with Windows 7. Now I’m off to restart.
I spent a few hours banging my head in frustration trying to get Windows 7 and my XBox 360 to work together. Windows Media Center was failing to connect, and not providing any helpful error messages. I dug through firewall rules, services, the event log viewer, anything I could think of, but nothing was working.
In the event viewer, under Applications and Services Logs -> Media Center, the only slightly helpful error I could find was “Media Center Extender Setup failed as the Extender was detected on the network but the UPnP search for the Extender failed (timed out after 20000ms).”
Anyway, long story short, it turns out that if Internet Connection Sharing is in use (which it is, I run an old wired router from my desktop’s ethernet connection to allow my television and blu-ray player to connect to the Internet), Media Center barfs and can’t connect. So the fix, in my case, was as simple as turning off Internet Sharing on my wireless connection.
I found no documentation on any of Microsoft’s support sites mentioning this as a reason for MCE to not work. In fact, their troubleshooting documentation is pretty crappy all around.
I found a fairly decent implementation of the Zenburn colour scheme for Microsoft’s Visual C++ 2010. It appears to work just fine with the Express version, so hat’s off to Luke Sampson for the “port”.
It’s available here (from studiostyl.es), with styles for the 2010, 2008 and 2005 versions of Visual Studio. The samples don’t show C/C++, but it looks pretty much like the C# sample. Here’s a snapshot:
Looks pretty good. Again, I use Envy Code R (see previous post for link). I might have to tweak it a bit as I’m not overly fond of bold fonts in code display, but it looks good.
I like the Visual Studio IDE. Unfortunately, I haven’t found a free-software alternative that offers the features of Microsoft’s IDE in an appealing and customizable way. I’ve tried CodeLite and Code::Blocks, and a handful of other environments, but there’s always something that irks me about them. I could bug the devs, or (gasp) contribute, I suppose, but instead I’ve taken the easy route and installed the Express Edition of Microsoft’s C++ environment.
While setting it up, I ran in to a small problem with the Windows SDK – it was failing with an unclear error. It turns out that if a newer version of the Visual C++ 2010 x86 redistributable package is installed, the SDK setup program barfs. Removing the redistributable package via Programs and Features allows the SDK setup to do what it’s supposed to.
The version I had was 10.0.4-something.
To use the newer SDK, it must be specified on a per-project basis via the project’s property sheets (Configuration Properties/General->Platform Toolset dropdown).
The Windows SDK Configuration Tool, included with the SDK, does not work with Visual Studio 2010 unfortunately. I would imagine one could edit the appropriate registry keys to set the updated SDK as the default, but a couple mouse clicks isn’t that inconvenient.
While Consolas is a nice enough fixed-pitch font for editing code, I prefer and recommend “Envy Code R” by Damien Guard. I find its slim, clean lines aesthetically pleasing (I also use it with MinGW in conjunction with mintty). Eventually I may try to figure out how to get 64-bit builds working (via the Windows DDK), but for now I’m off to find a decent Zenburn-like colour scheme for the IDE…
Here’s a few links if you’re interested in playing with VC++. Note that these are all legal links to Microsoft’s website, not some shifty “warez” crap.
I think I need to practice my writing skills a bit more. I usually get an idea for a post, but I peter out halfway through writing it. While I generally manage to convey the main points I wanted to, reading over it reveals just how lacking/crappy the article is. =)
After a recent update to the latest version of Logitech’s software for their keyboards, “Logitech Gaming Software”, the multimedia keys on my G110 stopped working (the play/pause, stop, previous and next keys).
The “fix”, for me, was pretty simple. Open up “Windows SideShow” from Control Panel and untick the checkboxes under the Windows Media Player gadget. I recall doing so when last I reinstalled Windows, but it took me a while to clue in that they had been turned back on after the last LGS update.
I’m just guessing, but I believe the WMP gadget is intercepting the multimedia key presses and not passing them along. Note that the G110 does not feature an LCD screen, so running the SideShow gadgets is pointless anyway.
