The GStreamer, Cairo Video Hackfest Results

Filed under
Software

Last month we talked about a hackfest to improve Linux video playback that came about after a GNOME developer began work on using Cairo/Pixman for raw video in GStreamer and looking at other ways to leverage hardware acceleration within this major open-source multimedia framework. This Linux video meeting started in Barcelona on Thursday and is ending today, with some accomplishments.

Some of the code that has been (and continues to be) worked on is merging YUV support into Cairo/Pixman, a GLX Multi-thread extension, merging gst-plugins-cairo, XRenderPutImage/XV to Pixmap support, VA-API support for GStreamer, and getting the GStreamer Cairo plug-in to work on the Nokia N900. Another proposal that came about this week was a libgstva.so abstraction library that would allow video acceleration support in GStreamer across back-ends for VA-API, VDPAU, XvBA, and other video acceleration APIs.

Early Benchmarks Of The Linux 4.9 DRM-Next Radeon/AMDGPU Drivers

While Linux 4.9 will not officially open for development until next week, the DRM-Next code is ready to roll with all major feature work having been committed by the different open-source Direct Rendering Manager drivers. In this article is some preliminary testing of this DRM-Next code as of 29 September when testing various AMD GPUs with the Radeon and AMDGPU DRM drivers. Linux 4.9 does bring compile-time-offered experimental support for the AMD Southern Islands GCN 1.0 hardware on AMDGPU, but that isn't the focus of this article. A follow-up comparison is being done with GCN 1.0/1.1 experimental support enabled to see the Radeon vs. AMDGPU performance difference on that hardware. For today's testing was a Radeon R7 370 to look at the Radeon DRM performance and for AMDGPU testing was the Radeon R9 285, R9 Fury, and RX 480. Benchmarks were done from the Linux 4.8 Git and Linux DRM-Next kernels as of 29 September. Read more

How to Effectively and Efficiently Edit Configuration Files in Linux

Every Linux administrator has to eventually (and manually) edit a configuration file. Whether you are setting up a web server, configuring a service to connect to a database, tweaking a bash script, or troubleshooting a network connection, you cannot avoid a dive deep into the heart of one or more configuration files. To some, the prospect of manually editing configuration files is akin to a nightmare. Wading through what seems like countless lines of options and comments can put you on the fast track for hair and sanity loss. Which, of course, isn’t true. In fact, most Linux administrators enjoy a good debugging or configuration challenge. Sifting through the minutiae of how a server or software functions is a great way to pass time. But this process doesn’t have to be an exercise in ineffective inefficiency. In fact, tools are available to you that go a very long way to make the editing of config files much, much easier. I’m going to introduce you to a few such tools, to ease some of the burden of your Linux admin duties. I’ll first discuss the command-line tools that are invaluable to the task of making configuration more efficient. Read more

Why Good Linux Sysadmins Use Markdown

The Markdown markup language is perfect for writing system administrator documentation: it is lightweight, versatile, and easy to learn, so you spend your time writing instead of fighting with formatting. The life of a Linux system administrator is complex and varied, and you know that documenting your work is a big time-saver. A documentation web server shared by you and your colleagues is a wonderful productivity tool. Most of us know simple HTML, and can whack up a web page as easily as writing plain text. But using Markdown is better. Read more
