Description Tim-Philipp Müller 2012-07-24 13:11:07 UTC 
Don't think it's stream-specific, happens with multiple streams.

Applies to 0.10 git/SDK and 0.11.

Works fine with latest 0.10 release (mpegtsdemux).

I'm not getting the segfault ... because it can't seek anymore. I get this message whenever I seek

0:00:30.827658710 29612 0x7f530c0556d0 ERROR               hlsdemux gsthlsdemux.c:966:gst_hls_demux_cache_fragments:<hlsdemux1> Could not fetch the child playlist http://ipad.akamai.com/Video_Content/cbc/being_erica/1240k/prog_index.m3u8

The tsdemux bug seems to be gone.

I fixed the bug that prevented any seek from happening (the GstUriDownloader was set to cancelled state but never reset on seek).
