GStreamer Hackfest 2015
Last weekend was the GStreamer Hackfest in Staines, UK, in the Samsung’s premises, who also sponsored the dinners and the lunches. Special thanks to Luis de Bethencourt, the almighty organizer!My main purpose was to sip one or two pints with the GStreamer folks and, secondarily, to talk about gstreamer-vaapi, WebKitGTK+ and the new OpenGL/ES support in gst-plugins-bad.
About gstreamer-vaapi, there were a couple questions about some problems shown in downstream (stable releases in distributions) which I was happy to announce that they are mostly fixed in upstream. On the other hand, Sebastian Dröge was worried about the existing support of GStreamer 0.10 and I answered him that its removal is already in the pipeline. He looked pleased.
Related with gstreamer-vaapi and the new GstGL, we tested and merged a patch for GLES2/EGL, so now it is possible to render VA-API decoded video through glimagesink with (nearly) zero-copy. Sadly, this is not currently possible using GLX. Along the way I found a silly bug that came from a previous patch of mine and fixed it; also, we fixed other small bug in the gluploader .
In the WebKitGTK+ realm, I worked on a new functionality: to share the OpenGL context and the display of the browser with the GStreamer pipeline. With it, we could add gl filters into the pipeline. But honour to whom honour is due: this patch is a split of a previous patch done by Philippe Normand. The ultimate goal is to ditch the custom video sink in WebKit and reuse the glimagesink, with it’s new off-screen rendering feature.
Finally, on Sunday’s afternoon, I walked around Richmond and it is beautiful.
Thanks to Igalia, Intel and all the sponsors that make possible the hackfest and my attendance.
