Over the past few weeks I did some work on porting Emotion to GStreamer 1.x. Emotion is the media library used by Enlightenment and part of the Enlightenment Foundation Libraries (EFL). It provides a media playback library abstraction (there are also Xine and VLC backends).
Previously there was a GStreamer 0.10 backend (which was the default one for Emotion), but GStreamer 0.10 is no longer maintained and supported by the community. At Centricular we want to make sure that GStreamer and other Free Software shine, so I started porting the backend to GStreamer 1.0.
I started doing a straightforward port of the old GStreamer 0.10 backend. That was a few hours of work, but the old 0.10 backend was rather bitrotten and was lacking a lot of features compared to the other backends. So I spent some more time on cleaning it up, fixing a lot of bugs on the way and making it (almost) feature-complete. Some of the new features I added were selection and switching of audio/video/text streams, support for the navigation interface for DVDs, buffering for network streams, improved support for live streams and proper support for non-1:1 pixel-aspect-ratios. I’ll work on adding some further features and improvements (like zerocopy rendering) to it over the next weeks every now and then, but overall I would say that this is ready for general use now and definitely an improvement over the old code.
The code can be found here and will also be in the 1.9 release, which will be released soonish. It’s also the default backend for Emotion now, and should give proper out-of-the-box multimedia experience with Enlightenment. The GStreamer 0.10 backend is still available but has to be enabled explicitly, if anybody needs it for whatever reason.
