style: cleanup unused includes and use consistent <> for external code (#1267) 2023-10-09 16:21:41 -07:00

feat: port media/base (#1127)
This removes all chromium dependencies from media/base/ and completes
the build system in CMake.

The ClosureThread class and its classes were removed, as they were
specific to chromium base. ClosureThread has been replaced by
std::thread.

The byte-swapping utilities in network_util.cc have been removed and
replaced with absl.

generate_unique_temp_path() was split out of file_unittest.cc into
file_test_util.cc, where other test suites could make use of it.

WARN_UNUSED_RESULT was replaced with the C++ standard attribute
[[nodiscard]].

The base::Clock interface was replaced with a typedef for a function
pointer that returns the current time.

This re-enables the tests in http_key_fetcher_unittest.cc by using
httpbin.org.

KongQun Yang 92e1e39868 Update MediaSample to avoid redundent copying
Use std::shared_ptr<const uint8_t> with a custom deleter to
represent MediaSample::data_ instead of std::vector<uint8_t>.

MediaSample::data_ can be shared by multiple MediaSamples and it is
immutable. A new data instance must be created if the clients want to
modify the underlying data. The new data instance can be transferred
to MediaSample using provided MediaSample::TransferData function.
This avoids unnecessary data copying.

Kongqun Yang c3d1dc1733 Deprecate STLDeleter and string_as_array
1. Replace STLDeleter with unique_ptr in container, which is
   supported in C++11
2. Replace string_as_array with &string[0] which is guaranteed
   to work in C++11

KongQun Yang 13202f91b6 Fix a few problems in AesCryptor classes
- CBC cryptors should accept IV of size 8 bytes - it will be zero
  extended to 16 bytes.
- Fixed iv() not updated problem in AesPatternCryptor.
- Replace kChainAcrossCalls with ConstantIvFlag enum flags.

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.
