qtdemux: Handle protection information in Sample Group Description (4.42 KB, patch)
2017-05-05 14:22 UTC, Seungha Yang 		none Details | Review

Description Seungha Yang 2017-05-05 14:20:37 UTC 
ISO/IEC 23001-7 Common encryption specification defines seig box
which can override default protection parameters of Track Encryption box (tenc).
Note that, Sample to Group box (sbgp) and Sample Group Description box (sgpd)
are required for parsing seig box, since sbgp and sgpd are linked structure
and seig is one type of child box of sgpd.

qtdemux: Handle protection information in Sample Group Description

Override default protection parameters by using defined sample group
Comment 3 Seungha Yang 2017-05-05 14:28:45 UTC 
Some DASH streams signal protection information by using seig boxes instead of tenc.
 
Note that in case of chromium, this box has been parsed from long long time ago...
