Rintaro Kuroiwa 300c23104e MuxerOptions and MuxerListener change for HLS 
- Add hls_name and hls_group_id fields to MuxerOptions. This is used to
  pass the NAME and GROUP-ID values for EXT-X-MEDIA tag to
  MuxerListener.
- Change MuxerListener::OnEncryptionInfoReady() to take an
  initialization vector.
- Change MuxerListener::OnNewSegment() to take segment name.
- Reworded and formatted MuxerListener comments to Doxygen style.

KongQun Yang 2ac57bf9b9 Use FOURCC as protection scheme parameter 
- Remove EncryptionMode enums
- Remove AesEncryptor::InitializeWithRandomIv, replaced with
  a static function AesCryptor::GenerateRandomIv, which should
  be called to generate the iv if the iv is empty.

This change is to prepare support for CBCS and CENS pattern-based
protection schemes.

KongQun Yang 5fc09763ce More cleanups in AesEncryptor and AesDecryptor 
- Create AesCryptor class as the common base
- AesCryptor::Crypt function will serve as an Encrypt function for
  encryptor and a Decrypt function for Decryptor.

KongQun Yang a9e5a2ff4f Refactor and optimize cbc encryption/decryption 
- Optimize and clean up encryption and decryption code.
- Consolidate various CBC encryption/decryption schemes into a
  common class.
- Make it a constructor argument whether cipher block chain is
  continuous across Encrypt/Decrypt calls.
- Also align protected region size as required in CENC spec.

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 144cdc5e59 Change to use ProtectionSystemSpecificInfo. 
* EncryptionKey now contains them rather than a PSSH box.
  * Outputs PSSH boxes for each entry.
  * Outputs a ContentProtection element for each entry.
* Removed SystemName and UUID from KeySource.
* Removed --scheme_id_uri packager argument.

Jacob Trimble d1d75f477c Add encryption support to WebM. 
This does not support key-rotation and will give an error.  This is
because WebM does not have a way to indicate a change in key ID using
media segments.
