Comment:

 Replying to [ticket:2172 devr]:
 > Summary of the bug:
 > ffmpeg 1.1 fails to produce a valid hls m3u8 live stream for iOS
 devices.
 >
 > What happens:
 > The iOS device stops playing the video after the end of the current m3u8
 file is reached.
 >
 > What should happen(this is the behaviour in version 1.0.3):
 > The ios device  checks cyclic for new content in m3u8 and plays the next
 segments and recalculates the length of the current stream.
 >
 > How to reproduce:
 > Start streaming a video and begin watching '''while''' encoding happens.
 > Video will only play as far as the current progress of the encoding has
 been at the time of starting playing the file.
 > iOS Device does not seem to realize that new "content" has been added
 and stream length has changed while watching the video.
