We've noticed that when we run a live stream with Flash and iOS streaming, that when the stream is killed, the iOS stream is cut off by about 15 seconds.
We are using Wowza 2.2.4, using the following encoder settings:
H.264, 30fps, 320x240, mp3 mono 64k.
We also notice a similar issue using SHOUTcast, although the cut off is somewhat less, generally around 7 seconds.
You can test this by recording yourself counting down seconds from 30. When you get to 0, kill the encode. Flash plays through to the moment you stop, but iOS will cut off anywhere from 7 to 21 in our experience. We are using the default iOS chunk settings.
Does anyone else have this issue, and is there a workaround for it?
