Web overlay in GStreamer with WPEWebKit
After a year or two of hiatus I attended the GStreamer conference which happened in beautiful Edinburgh. It was great to meet the friends from the community again and learn about what’s going on in the multimedia world. The quality of the talks was great, the videos are published online as usual in Ubicast. I delivered a talk about the Multimedia support in WPEWebKit, you can watch it there and the slides are also available.
One of the many interesting presentations was about GStreamer for cloud-based live video. Usually anything with the word cloud would tend to draw my attention away but for some reason I attended this presentation, and didn’t regret it! The last demo presented by the BBC folks was about overlaying Web content on native video streams. It’s an interesting use-case for live TV broadcasting for instance. A web page provides dynamic notifications popping up and down, the web page is rendered with a transparent background and blended over the live video stream. The BBC folks implemented a GStreamer source element relying on CEF for their Brave project.

GStreamer’s playbin3 overview for application developers
Multimedia applications based on GStreamer usually handle playback with the playbin element. I recently added support for playbin3 in WebKit. This post aims to document the changes needed on application side to support this new generation flavour of playbin.
So, first of, why is it named playbin3 anyway? The GStreamer 0.10.x series had a playbin element but a first rewrite (playbin2) made it obsolete in the GStreamer 1.x series. So playbin2 was renamed to playbin. That’s why a second rewrite is nicknamed playbin3, I suppose
