Description Nirmal Palanisamy 2017-08-09 14:15:32 UTC 
As per ISOBMFF spec,

reference_type: when set to 1 indicates that the reference is to a segment index (‘sidx’) box;
otherwise the reference is to media content

This behavior is observed in the below MPD 
http://dash.akamaized.net/dash264/TestCases/1a/sony/SNE_DASH_SD_CASE1A_REVISED.mpd

In the attached patch, second level of SIDX is parsed and table is formed which refers to MOOF box.

This is probably not enough yet. The other SIDX tables with reference_type==0 could be anywhere in the stream before the corresponding moof boxes, and we need to parse them correctly then and remember them all somehow.

And when seeking we need to first go to the corresponding SIDX table somewhere in the file to then find the position of the moof from it.
