Twitch HLS playlist

I could not track down which component actually fails here. I'm trying to
playback a HLS stream with gst-play-1.0.

This is a playlist from Twitch.tv. You need an application token and use their
API to get the playlist - which is only valid for a certain amount of time
which makes it a little inconvenient.

However gst-play-1.0 fails very quickly with the following error:

$ gst-play-1.0 broken.m3u8
[..]
WARNING No decoder available for type 'text/uri-list'.
WARNING debug information: gsturidecodebin.c(938): void

Reached end of play list.


I noticed that in the playlist file one of the first entries is a custom
#EXT-X-TWITCH-INFO line. I tried removing that line and the HLS stream played
just fine.

The attached playlist probably won't work anymore due to the session expired -
but can be still value for testing as gst-play-1.0 at least tries to play the
modified playlistthe stream does not error out immediately.

Do I need special handling for this type of playlist or is this a bug?
