- Also import the version of the protobuf bundled in packager first,
this avoids importing the installed version of the protobuf, which
may not be compatible with this script.
- Print help if no argument is supplied.

Some subtitle files use .webvtt instead of .vtt, probably because
ffmpeg uses -f webvtt when converting from some other format.

- Add decrypt_config in media sample and stream.
- Update subsamples when converting NAL unit to bytestream.

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
Change-Id: I7f39c0e51fc8a3fcbb41313094a0ca6b33db7bf3
Also updated packager_test not to fill in output_format by default,
which will help catch these kinds of bugs.

This flag is needed to workaround the Chromium bug
https://crbug.com/398130, which uses decoding timestamp
in buffered range.

Since the |extra_data| field contains codec-specific configuration
data, it makes sense to call it |codec_config|.

- Add flags and stream descriptor fields for HLS.
- Remove fields from MuxerOptions. Instead pass them directly to
HlsNotifyMuxerListener.
- Rebase segment names to the master playlist's path where it makes
sense.

- 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.

This is part of the effort to support Opus in iso-bmff #83.
Changes in this CL:
- Add support for multiple SampleGroupDescription and SampleToGroup
boxes in TrackFragment box;
- Add support for SampleGroupDescription and SampleToGroup boxes
in SampleTable box;
- Add support for AudioRollRecoveryEntry in Sample Group and 'roll'
sample grouping type;
- Also fix a bug that default length was not set correctly in
SampleGroupDescription when constant iv is used.

- For encrypted segments, PMT specified by SAMPLE-AES specification is
generated.
- Remove time_scale_ field from TsWriter. It is not used.
- Move ContinuityCounter to a separate file.
- Add ProgramMapTableWriter and implementations.
- continuity_counter is incremented for PAT and PMT.
Change-Id: If0dd0990203cb6990f39a6832048bdc3ff08decd
- These warning messages are not useful since the code needs to
loop through various container types to find a matching one.
Change-Id: I1d8eca563faf24e485ac71cce32e09515c174bf2
- 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.
Change-Id: I3fb4de0e8abbe891e6271e779373ba53f8df660d
- 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.
Issue #85
Change-Id: Iea06e68552a56ae180177ffd6ca315a7cf39456c
- 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.

- FOURCC is not a mp4 only concept. It is also used elsewhere.
- RCHECK has been used outside formats/mp4.
Also updated the FOURCC enum names to match the actual fourcc code, e.g.
FOURCC_mdat for "mdat".
Change-Id: I5be02f12695882c0fb41d359305fb8ec01303a06
- Create AesCryptor class as the common base
- AesCryptor::Crypt function will serve as an Encrypt function for
encryptor and a Decrypt function for Decryptor.
Change-Id: Ie91fb14964b5091786705bf510656f40d73af160
- 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.

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.
Closes#88
Change-Id: Ic719b19747530f0e4856cfb36471a644d572a734
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
Change-Id: I4bd0290f6d8b965f7d118f075c96e0f267d7e831
- 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.
Issue #77
Change-Id: I3a9304d89adf5efbfb226b6e805a3077b6cb8c68
* 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.

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.
Change-Id: I6f4633facad39207809ffbad970635d1f9d70983
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.
