Kongqun Yang d08f6ae0cc Fix cbcs/cens behavior when applied to non video tracks
- Tracks other than video are protected using whole-block full-sample
  encryption as specified in ISO/IEC 23001-7:2016(E) 9.7, which is
  equivalent to a pattern of 1:0. This is different to the non pattern
  encryption counterparts.
- Also updated the code to allow the existence of other protection
  schemes in the original content, which will simply be ignored.
- The internal cryptor used by AesPatternCryptor should not use
  constant iv, add a DCHECK for that.
- Optimize AesPatternCryptor handling on the special pattern 1:0.

Jacob Trimble c9645bc21b Add a utility script used to generate/parse PSSH boxes.
This script can be used to parse and generate PSSH boxes.  This
serves two purposes:

* Parse PSSH boxes into a human readable format.
* Take several arguments to generate PSSH boxes.

This is also able to parse Widevine and PlayReady PSSH data and will
print the parsed data instead of the data as binary.  This can also
generate Widevine PSSH data instead of having the PSSH data passed
as an argument.

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.

Jacob Trimble e7926e7ccb Fixed mac build for H.265 parser.
Another feature that the mac build does not support.  It incorrectly
uses a copy-constructor when creating new values in a std::map.  This
is incorrect and should use an in-place constructor with C++11.

Jacob Trimble cdcfc4c44b Added H.265 parser.
This adds a preliminary H.265 parser.  The parser only support
reading the slice header.  This also attaches the H.265 parser to the
VideoSliceHeaderReader so H.265 frames can have unencrypted headers.

Jacob Trimble 6f8cbf90b9 Add packager flag to include common PSSH with Widevine.
The flag --include_common_pssh will add another PSSH box in addition
to the Widevine one which will contain the key IDs of all the keys.

Rintaro Kuroiwa 94b4c52bf5 packager test should respect builddir_name
- Use 'builddir_name' environment variable to create the output
  path in test_env.py
- This allows running the packager test with different build
  configs because it doesn't use 'out', e.g. it could use 'out_clang'
  for clang builds.

KongQun Yang 0c46943177 Improve handling of unescaped NAL units in byte stream
The new algorithm will parse NAL unit header and only starts a new
NAL unit if it is valid, otherwise it will be considered part of
the previous NAL unit.

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 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.

Joey Parrish f3e19fc002 Split AdaptationSets by content type, container, codec, and language
This adds a new function to key AdaptationSets based on the
characteristics that require separate sets.

With this, we are now able to package multi-codec assets at once
(AVC1/MP4 and VP9/WebM in the same manifest, but in different
AdaptationSets).

Joey Parrish b6718a37c5 Accept language subtags
When normalizing language tags to their shortest form, we need to
split off subtags and treat them as separate components that do not
get changed.

Furthermore, MP4 can only store language tags without subtags.  So
only store the main language in MP4 output.

This does not currently work on our mac builds, so this replaces it
with push_back.

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.

2016-03-07 19:10:42 -08:00
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.

This moves common parsing code out of the H.264 parser.  This is in
preparation for the H.265 parser to use.

Jacob Trimble 0803e31836 Read SPS/PPS Nalus from decoder configurations.
Now the AVCDecoderConfiguration and HEVCDecoderConfiguration classes
will read the Nalu from the blocks, meaning they will store a
vector of Nalu objects for the data.

Also added H.265 to the Nalu class and added argument to NaluReader
to read H.264 vs H.265 Nalus.

KongQun Yang 91b43773fd Update hevc test file to have more than one key frames
This is needed to test encryption in end to end test since the video
is segmented in gop boundary by default. Due to the existence of clear
lead, the first segment is always left in clear.

Jacob Trimble 53e6d2d149 Renamed Nalu |data_size| to |payload_size|.
This member refers to the size of the payload (the data after the
header).  Since the pointer is called |data|, calling this size
|data_size| is confusing.

Jacob Trimble 0d3951ff74 Moved Nalu data pointer position.
Now the Nalu data pointer points to the start of the NALU header
rather than pointing to the start code.  Added a new method on
NaluReader to check whether the stream starts with a start code.
