to come back to my issue,
is it perhaps somehow possible to choose the segment where i start the 
connection, ive seen in the m3u8 files thata there are always also older 
segments listed not only the actual one.

and who to i define the time to analyze the stream with 
avformat_open_input, i tried already:

av_dict_set(&this->avoption, "probesize",           "15000", 
         av_dict_set(&this->avoption, "fpsprobesize",        "120", 
         av_dict_set(&this->avoption, "analyzeduration",     "15000", 

but it takes always 30 seconds before this gives me an OK back
