For the lazy, these are some of the topics we’ll be covering: Vision and mission — where we are and where we want to be Improving our patch review process [...]

Androidifying your autotools build the easy way

By Arun | Published: May 2, 2012

Derek Foreman has finally written up a nice blog post about his Androgenizer tool, which we’ve used for porting PulseAudio, GStreamer, Wayland, Telepathy and most of their dependencies to Android. If you’ve got an autotools-based project that you’d like to build on Android, whether on the NDK or system-wide this is really useful.

PulseAudio on Android: Part 2

By Arun | Published: April 30, 2012

Some of you might’ve noticed that there has been a bunch of work happening here at Collabora on making cool open source technologies such as GStreamer, Telepathy, Wayland and of course, PulseAudio available on Android. Since my last blog post on this subject, I got some time to start looking at replacing AudioFlinger (recap: that’s [...]

PulseAudio vs. AudioFlinger: Fight!

By Arun | Published: January 16, 2012

I’ve been meaning to try this for a while, and we’ve heard a number of requests from the community as well. Recently, I got some time here at Collabora to give it a go — that is, to get PulseAudio running on an Android device and see how it compares with Android’s AudioFlinger. The Contenders [...]

i’m in yur analog gain, controlling it

By Arun | Published: November 8, 2011

Longish day, but I did want to post something fun before going to sleep — I just pushed out patches to hook up the WebRTC folks’ analog gain control to PulseAudio. So your mic will automatically adjust the input level based on how loud you’re speaking. It’s quite quick to adapt if you’re too loud, [...]

Alternate sample rates

By Arun | Published: October 18, 2011

I’ve just pushed a bunch of patches by Pierre-Louis Bossart that can have a pretty decent CPU/power impact. These introduce the concept of an “alternate sample rate”. Currently, PulseAudio runs all your devices at a default sample rate, which is set to 44.1 kHz on most systems (this can be configured). All streams running at [...]

Hello … hello … hello!

By Arun | Published: August 25, 2011

I have a secret to confess. I’ve spent a great deal of time over the last few months talking to myself. I can’t say I haven’t enjoyed it — it turns out my capacity to entertain myself is far greater than initially suspected. But I hear you ask … why? Here at Collabora, I’ve been [...]

(Gst)Discovering Vala

By Arun | Published: January 16, 2010

My exploits at Collabora Multimedia currently involve a brief detour into hacking on Rygel, specifically improving the DLNA profile name guessing. We wanted to use Edward‘s work on GstDiscoverer work, and Rygel is written in Vala, so the first thing to do was write Vala bindings for GstDiscoverer. This turned out to be somewhat easier [...]
