 Hi guys i am just trying to restream a live stream as hls
 but ffmpeg doesnt give an error doesnt crash does not exit process
 it just hangs,stucks,freezes whatever you call
 because of that my live stream stops and i have to restart it every 5-10
 minutes by my hand and not sure what is the reason

 here is my commandline

 {{{
 ffmpeg -loglevel debug -thread_queue_size 32768 -i "http://goo.gl/MOFvg5"
 -preset veryfast -f hls -hls_time 5 -hls_list_size 5 -hls_allow_cache 1
 -hls_flags delete_segments -segment_list_flags +live -hls_base_url
 "../ts/" -hls_segment_filename "C:\nginx\html\ts\stream-%%3d.ts" -y
 "C:\nginx\html\hls\stream.m3u8" > log.txt
 }}}

 i tried 32 bit , 64 bit , nightly builds, 3.2 version all are same

 here is example output log
