adaptivedemux: Pre-rolling problem after seeks on HLS streams
Submitted by Roland Jon @rland
Link to original bug (#787621)
Description
Created attachment 359702
Reproduce unit test code
gstplayer in pause state, seek to a specific point, will cause the pipeline to hangs.
Attached unit_test will perform a seek to user specified position in PAUSED state,
such as:./gst-play http://10.9.44.116/seek_issure/index.m3u8 90000
The HLS file for reproduction is here：
https://drive.google.com/file/d/0B8t5E5lSOxhHOEo2akNZQW9MX2s/view?usp=sharing
The seek location set to 90000, 100% will hangs, audio seems unable to preroll success, and the video has been preroll completed.
backtrace:
