Comment (by FernetMenta):

 First pass a hls playlist to ffmpeg like this one:
 http://qthttp.apple.com.edgesuite.net/1010qwoeiuryfg/sl.m3u8

 ffmpeg hls demuxer will read the first segment of the 8 items of this
 playlist. Depending on the bandwidth of your internet connection this may
 take a while. OP of ticket 17422 reported 6 seconds.

 Now pass only one item of this playlist:
 http://qthttp.apple.com.edgesuite.net/1010qwoeiuryfg/1240_vod.m3u8

 This is much faster.

 The problem is that ffmpeg spends the time in avformat_open_input not in
 analyze_streams. The latter allows a timeout. If the hls playlist is long
 enough, ffmpeg fails on open.
