           Summary: hlsdemux: Saving IV from media sequence number is done
                    out of file->iv structure
    Classification: Platform
           Product: GStreamer
           Version: 1.3.2

[10:59] <damianZiobro> hi I am analyzing code of hlsdemux and I found bug there
[10:59] <damianZiobro> in gst-plugins-bad version 1.3.2
[11:00] <damianZiobro> file ext/hls/m3u8.c line 352
[11:00] <damianZiobro> there is such code there:
[11:00] <damianZiobro>            guint8 *iv = file->iv + 12;            
GST_WRITE_UINT32_BE (iv + 12, file->sequence);
[11:00] <damianZiobro> so we are basically moving 12 bytes two times
[11:00] <damianZiobro> file->iv structure has 16 bytes
[11:01] <damianZiobro> so wile we are moving 12 bytes 2 times we are out of
structure which we are trying to write to
[11:01] <damianZiobro> I think it is bug
[11:01] <damianZiobro> moving 12 bytes should be done only once
