Jacob Trimble d5cdd00ba1 Move fixed key encryption code to new FixedKeySource.
KeySource is now an abstract class that is implemented in two
types WidevineKeySource and FixedKeySource.  This also updates
fixed key encryption to use v1 PSSH boxes with the common system
ID.

This also updates the --pssh argument.  Now it accepts full PSSH
boxes rather than data.  Multiple PSSH boxes can be concatenated
together.

Bei Li e39c3572af Add support for "AES 128-bit Cipher Block Chaining (CBC-128) Encryption"
- Part 1.

- Add packager command line argument "protection_scheme" to specify
  protection scheme. Plumb through packager code to enable CBC
  encryption/decryption.
- Add scheme type "cbc1" to sinf.
- Refactor AES encryptor and decryptor.
- Need more work in the subsample handling.

Jacob Trimble c4246d04fd Change FetchKey usages.
Add another overload to fetch by key ID directly, used by WebM.
Changed the one using PSSH data in favor of the entire PSSH box.

This also moves the Widevine proto to media base.  Now, the
Widevine key source handles creating the Widevine specific PSSH
data.

Jacob Trimble 9d67f545ed Add support for v1 PSSH boxes.
This moves pssh parsing to its own class in media base.  This type
can be used to parse and generate pssh boxes.  This new type also
supports both v0 an v1 boxes.

This also modifies the pssh box definition to only have the |raw_box|
and moves all pssh parsing and handling into mp4 media parser.

A follow-up change will replace the remaining usages of 'raw' pssh
box data with the new type.

Anders Hasselqvist db7bebe3fa MacOSX: Solve libbase.a conflict link error
On Linux the generated ninja files use path/libbase.a as target name.
In the Mac ninja file the target is just libbase.a.
As we have two libbase.a (base/base.gyp and media/base/media_base.gyp) the linking stage fails to include both libs.

Solve by renaming media_base.gyp's base target to media_base

KongQun Yang e0040a4910 Add version information in generated outputs
For mp4 outputs, a metadata box with version information is added to
moov box.

For mpd outputs, a text comment with version information is added in
the beginning of mpd file.

Kongqun Yang 2a95367dd4 Move SAR extraction out of video_stream_info.cc
This fixes a circular dependency of media_base depends on filter and
filter depends on media_base.

Also added code to extract sar in WvmMediaParser if it is not yet
extracted when setting extra_data.

Rintaro Kuroiwa c3c971ebd9 Add pixel_{width,height} to VideoStreamInfo
- Added logic to container parsers to extract pixel width and height.
- If the container doesn't contain the pixel width and height of the
  stream and the stream is H264, this parses the SPS to get the
  sar_width and sar_height.
- If extracted sar_width and sar_height are 0s then they imply 1s.
- Add hb2_v_frag.mp4 for test media. This does not have a
  'pasp' box and has sar_width = 8 sar_height = 9.

KongQun Yang e685dd1a73 Move test files in media/base to test directory
Also rename mpd/base/bandwidth_estimator_test.cc to
bandwidth_estimator_unittest.cc for consistency.

And remove mpd/base/simple_vod_mpd_notifier.* as they are not used
anywhere.
