Description
GStreamer’s playbin3 element provides a convenient and simple interface for basic media playback. Like earlier playbin elements, it has some support for external subtitles, but with some limitations. Extending it to handle multiple auxiliary streams - such as multiple audio or subtitle tracks - reveals a surprising number of complexities.
This talk delves into the challenges faced when adding robust auxiliary stream support to playbin3, covering bugs found, pipeline negotiation intricacies, state management issues, and the corner cases that arose.
