- Deprecated command line flags --profile and --single_segment.
'segment_template' in stream descriptors implies live profile
and non-single segment.
- Added flag --generate_static_mpd_for_live_profile to generate
static mpd for live profile; if not set, dynamic mpd will be
generated.
Close#142
Change-Id: I78879297ed118f0f246c4753a16ad125bd6b5e4f
- Added two new fields in MpdOptions: dash_profile and mpd_type
- Updated MpdBuilder to support LiveProfile with static mpd
- Command line arguments will be updated in the next CL
Issue #142
Change-Id: Ibd35e5c9e1b1ef98043392e3f04a0af4700135c1
Current mechanism of using AdaptationSet @group is not spec compliant.
The spec compliant mechanism is to use supplemental descriptor with
schemeIdUri: urn:mpeg:dash:adaptation-set-switching:2016 as specified
in ISO/IEC 23009-1:2014/Amd.4:2016.

Three options are supported right now:
- reuse=1|0
Allow or disallow reusing UDP sockets. Default 0.
- interface=a.b.c.d
Address of the interface over which to receive UDP multicast
streams.
- timeout=microseconds
Timeout in microseconds. Default to unlimited.
A UDP url should be of the form udp://ip:port[?options], here
is an example:
udp://224.1.2.30:88?reuse=1&interface=10.11.12.13&timeout=12345
Also deprecate --udp_interface_address flag in favor udp options.

Cues used to be generated in the end of the file; if http range
request is not supported, clients have to download the whole
file to get to the cues.
This CL updated TwoPassSingleSegmentSegmenter to write cues
after writing webm header.
This CL also updates libwebm dependency to latest.

Setting this flag will tag any matching tracks with kRoleMain.
The player will then know which tracks should be default when there
is not a language match.
Closes#155
Change-Id: I827304c49e345d07b1e76f7a46421b60f228f0ba
Language tags can have subtags, such as "por-BR". While the base tag
should be 3 characters, the entire tag can be longer. Rather than
parse out the base tag and check that it is size 3 without the subtag,
we can just trust the ISO tag converter to do the right thing.

- Also regenerated test content to insert an iframe every one
second: ffmpeg -i source.webm -auto-alt-ref 1 -g 30 out.webm
This makes sure the content is actually encrypted with one
second clear lead in end to end test.

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

The current behavior of logging to a file in the same directory
as the binary will break if the binary does not have write access
to that directory.

Change-Id: I11adfaec676fc9bbef2a5caa3261889d1fba3b88
Mimic iso-bmff behavior: either all the samples in a segment are encrypted
or all the samples are clear.

The right way to detect the presence of a keyframe in a BlockGroup
is to look for the absence of the ReferenceBlock element [1].

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

- Try to determine container name from segment_template if output is
not specified
- segment_template descriptor is required for TS
- output descriptor should not be specified for TS
- Generate hls_playlist_name from stream number if not specified

Change-Id: Ide7169f1c26c85a6e38272dda0e1af77135b4d90
- 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.

- 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.

- Disallow packager_test.py to be executed from source directory
- Remove the building of packager target from packager_test.py. User
need to make sure packager builds successfully before running
the test.
- Remove build_type parameter which is no longer needed
Change-Id: I479d3c39b8d45730e5388d194069f1320fa5cd75
- 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
- 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.

Tracks and SegmentInfo.

- Optimize and clean up encryption and decryption code.
