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.

Issue #88

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.

vector::data() introduced in C++11 does exactly what vector_as_array does.

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 2c3aed4842 Handle possible NewSampleEvent before ParserInitEvent
For WebM contents, it is possible that we may receive some NewSampleEvent
before receiving ParserInitEvent. This is because init event is fired
after analyzing a video block which could come after an audio block.

Also modified Flush() function to return a bool to indicate whether the
the flush is successful and whether the samples are handled correctly.

And added macro to ensure Flush() and Parse() results are handled.

Fixes #71

Kongqun Yang 3a5fdd2d9c Fix incorrect width/height in VisualSampleEntry for mp2t stream with cropping
Cropping is necessary if width/height are not exactly disivible by 16 due
to 16x16 macroblock size.

The width and height fields in VisualSampleEntry must correctly document
the cropped frame dimentions (visual presentation size) of the AVC stream
that is described by that entry.

Also fixes width/height in input mp4 and wvm streams if the values in
VisualSampleEntry / metadata do not match with the values in
AVCDecoderConfigurationRecord (SPS).

Issue: 39

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.

consideration.
