Kongqun Yang b9f1996b68 Fix compilation errors after manifest update 
Manifest was updated in CL 7debbbe19b158ea7377e229a17ec1d3d9d19d1b8
to point to Chromium LGKR CL 253526.

There are some API refactoring in base, which result in some code
changes in our packager source.

Kongqun Yang b93f2020c8 Fix no ContentProtection element problem. 
The original code used stream_info.is_encrypted() to check whether output
stream is encrypted; However, stream_info contains input stream
information and does not contain output stream infomation, which results
in incorrect status was passed to mpd generator. Fix the problem with
correct information from muxer.

Change on behalf of rkuroiwa after a discussion with him.
