Tearing with nVidia drivers and mplayer with "-vo xv"

Well, let’s start with the conclusion: setting XV_SYNC_TO_VBLANK has no effect, if a second monitor is attached.

But let’s start at the very beginning: What is tearing? Well, this is how Wikipedia defines it:

Screen tearing is a phenomenon in video where a previously rendered frame overlaps a newly rendered frame, creating a torn look as two parts of an object (such as a wall) don’t line up…

Adobe Flash Player 10 and Hardware Acceleration for Linux

A buzz word is going around: hardware acceleration regarding Linux and GPU usage

Adobe has announced the finale release of its Flash Player. The Version 10.
It’s been said, it’s capable of using hardware acceleration under Linux, and that may be the truth actually. But – we are not talking about H.264 acceleration and we are talking about more limitation than only that: Read the blog of Kaourantin for more details. Or a more brief story here.
The statement, Linux won’t have hardware acceleraton for H.264 content in near future is as real as before.
But now I know at least why my fullscreen flash playback gave me 5 frames/sec. It’s because I’m using compiz. This is a no-go combination.

Stuttgart by Bicycle

Navigating with GPS and a bike in the Stuttgart area? No problem anymore: VVS Fahrradroutenplaner
I’m just impressed! I’ve been using this many times now. And in combination with Google Earth, it’s perfect tool to get everywhere in my area.
Just a little tip: In Google Earth you can let mountain look 3 times higher, than they really are. That way it’s much clearer to see, if one track is easy, normal, difficult, or almost impossible to do by bike.
You can set it up under: Continue reading “Stuttgart by Bicycle”

Open Street Map for Cyclers

I’m looking periodically into this site: OpenCycleMap . I’m just interested, whether there’s a new GPS-track I can use for a trip. I’m also playing with the thought to cache some data to and provide it, too.
The map shows Great Britain, because the project stated there. The Netherlands offers also a lot of tracks already. Germany, Swiss, Sweden, Poland and a few other countries have also a few tracks to offer.
Also the east cost of the United States has a few tracks. And it’s getting more every single day.

Issues with CoreAVC

I’m trying to run CoreAVC on Linux. The version I’m using is CoreAVC 1.8.0.
But it doesn’t work for footage from Canon’s HF100 or the Panasonic HDC-SD100. It’s stutter as hell if one let it run in interlaced mode, and if you are going to seek within the content, the playback behaves like a slideshow afterwards. Here’s my post I’ve send: Continue reading “Issues with CoreAVC”
