Re: gstreamer openmax

Yes Wheezy is the key. I have been using Raspbian but the "official" Debian Wheezy will do the job. I can't remember what I installed. I know I installed all the gstreamer packages and most likely the -dev versions and a few other things. I may have even done an apt-get build-dep on gstreamer. Havin...

Re: gstreamer openmax

I think -omx is a fork but I can't remember the details. I got both to build and got configs that were dl-opening the openmax libs but I couldn't work out how to get a pipeline going or even if the config files were right. I wish someone could tell us what needs to be done. It would be such a big wi...

It looks like a Debian Wheezy is available for testing and Raspbian which is also Wheezy has boost 1.46, 1.48 and 1.49 available.

Re: Great SDHC card that's cheap and works.

What is the benefit of buying a Class 10 card for the Pi? Just curious because casual benchmarking on my Pi suggests that the sd interface is the bottleneck and faster cards bring no benefit but I haven't tried anything fancier than a class 6.

Re: 8000 interrupts per second when idle!

No expert but google tells me usb frames happen every 1ms. USB 2 divides them up into 8 microframes to increase performance. So 8000 of them a second. The thing isn't being driven by events as you might expect but by a clock. I am guessing you can't slow the clock down or the usb device doesn't just...

Re: [debian] No keyboard/mouse after startx

I don't use rpi-update (yet) but look at the source it does a depmod after a kernel update so it should work as in "does" unless something goes very wrong such as a crash during the update.

Re: Keys keep locking

I am happy to be proven wrong but I think people are too quick to blame power issues. They certainly exist. But I would wager the missing usb packets are a kernel driver bug since I get the problem with multiple keyboards and the problem only gets worse on a powered hub.

Re: [debian] No keyboard/mouse after startx

If after a kernel upgrade you have keyboard at console but no input in X windows it is almost always due to your system not being able to load the evdev module. You can confirm this by doing an lsmod and looking for evdev. If evdev is not listed check to see if the modules were installed. People may...

The funny thing is that even with 8000 interrupts per second the Pi still misses some of my key presses. You would think it could just do a poll every hundredth of a second and see I am not pressing a key anymore :-) And @dom, would it be correct to say this is a feature of the driver or the hardwar...

The sound problem above is probably something with the kernel alsa driver which hopefully will mature separately. Another problems I noticed was running on the framebuffer.
