--- Comment #2 from Charlie Turner <cturner at igalia.com> ---
At the moment, GStreamer can't support the use case required by WebKit. HTMLMediaElement expects a progress event within three seconds. The only way we have of getting progress information is from buffering events at the moment.

Unfortunately, for many real-world HLS streams, it takes longer than 3 seconds before those events even get sent. Our current strategy for progress information is to poll the pipeline with buffering queries. We can't poll the HLS pipeline for buffering information, because the hlsdemux element doesn't support buffer queries, and the GStreamer people don't think it should.

Will have to investigate other ways of reporting progress here. Perhaps just using the manifest download result as a sign of progress will be a decent approach.
