 Summary of the bug:

 I am trying to record and segment a live stream and save it in two output
 files: video and audio , but the generated video and audio  segment files
 are not always synched , for example the video length is 120 seconds while
 the audio file length is 124 seconds!  the command to reproduce this is:

 ffmpeg -loglevel 40 -re -i http://alarabiya-geo-
 live.hls.adaptive.level3.net/hls-live/alarabiya-
 channel01/_definst_/live/stream1.m3u8 -f segment -segment_time 120
 ARA%07d.mp4 -f segment -segment_time 120 -ac 1 -ar 16000 ARA%07d.wav

 How to reproduce:
 {{{
 % ffmpeg -loglevel 40 -re -i http://alarabiya-geo-
 live.hls.adaptive.level3.net/hls-live/alarabiya-
 channel01/_definst_/live/stream1.m3u8 -f segment -segment_time 120
 BBC%07d.mp4 -f segment -segment_time 120 -ac 1 -ar 16000 BBC%07d.wav
 ffmpeg version
 built on ...
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
