On a PC running Win10Pro64 that has no Firewire port i needed a 4in4out audio solution functioning as an ASIO device. So i dug out my E-MU 1616m PCIe, and – fearing that it would show severe compatibility issues – installed the most recent driver (EmuPMX_PCDrv_US_2_30_00.exe, July 15th 2011). To my surprise, the device started […]

xdraw 1.1
5. Mai 2017 in Multimedia, Programmierung.
I was very pleased to notice that my small Xlib-utility xdraw has made it across the years unscathed. It compiled after 11 years of complete lack of code or build system maintenance. Hail to the stability of the X Library! However, i found the visual quality of the drawing results a bit lacking – the […]

Stabilize Shaky Video With ffmpeg and vidstab
5. Oktober 2015 in Multimedia, Technik.
Overview On my walking and hiking tours i often do not carry my camera but only my Android phone. Unlike the camera, the phone features no image stabilization mechanism whatsoever. In the past i have used the option offered by Google’s YouTube to apply a transformation that compensates for the most unfriendly effects of my […]
„jack-autostart“ – Setup and Start Scripts for jackd
9. September 2015 in GNU/Linux, Multimedia, Programmierung, Technik.
„jack-autostart“ is essentially a start script (I use it for my XFCE sessions) that starts „jackd“ with appropriate command line parameters and configures as many applications as possible to route playback to the JACK service. For this purpose, redirect all ALSA playback to JACK, and set JACK as default audiosink/-source for GStreamer.
DTP With Free Software?
31. Juli 2015 in Multimedia, Technik.
In case anyone is wondering how to produce documents with complex structure, multiple pages and professional quality using free software, the answer is of course: with LaTeX. Consider the alternatives: Office (Libre, Open, the KDE stuff) are a nuisance when it comes to properly customized sectioning, and for larger documents or 100% precise positioning they […]

Mobile Version 1.0: jQuery Mobile
8. Januar 2015 in Multimedia, Programmierung, Technik.
As an experiment, I have implemented a „mobile version“ for my website with jQuery Mobile. The downside of that framework is that even the customized (stripped-down), minimized format that I am using still consumes about 200 kilobytes, and that is more than the entirety of my desktop-version start page altogether. This excessive network traffic consumption […]
