The KeySource now only handles fetching the keys and loading any PSSH
info from the license; it will not handle generating new PSSH info
based on the config.
This will allow the PSSH generation to access to the full
EncryptionConfig so we can add additional options to it.

There were several enum types that all were used for key systems. This
combines them into one to make it more clear and only needing to update
one. This also uses a bit field to specify multiple key systems instead
of using a std::vector.

The resolution values are uninitialized when parsing AVC decoder
configuration record if it does not contain parameter sets (SPS/PPS),
thus they could contain undefined values.

Opening a named pipe can block until both ends are open, and we cannot
control when the other end will be open. Ideally, we would always
open files in a thread so that Packager can be used with piped inputs
from naive applications without a potential deadlock.
This change will defer opening WebVTT files until the parser Run()
method is called from a thread. This way, WebVTT files being sent in
from a pipe will never be able to block the main thread.
Previously, files were opened on the main thread before calling the
parser constructor, passing the open file to the constructor as an
argument. I also tried doing it in the parser's InitializeInternal()
method, but that is also called from the main thread.

Under command line flag --mvex_before_trak.
This is needed to workaround Android MediaExtractor bug which
requires |mvex| to appear before |trak|.
Closes#711.

Added --crypt_byte_block, --skip_byte_block to allow users to specify
protection pattern other than 1:9 for pattern based encryption scheme,
e.g. cbcs and cens.

AV1-ISOBMFF spec is updated recently to use start alignment instead of
end alignment for cbcs:
for the protected scheme cbcs:
- BytesOfProtectedData SHALL start on the first byte and end on the
last byte of the decode_tile structure (including any trailing bits).
- A subsample SHALL be created for each tile, even if its size is less
than 16 bytes.
- ...
cenc protection scheme is not affected.
Closes#698.

Remove custom constructors, which is no longer needed with C++11. Use

Added Dolby Vision backward compatible signalling, i.e. for Dolby Vision
profile 8, both base codec without Dolby Vision and HDR codec with Dolby
Vision are signalled.
This is achieved by using a new MuxerListener implementation
MultiCodecMuxerListener, which wraps multiple child MuxerListeners and
is able to delegate to the child MuxerListeners based on the codecs in
the stream.
Closes#341.

Call CRYPTO_library_init to properly initialize crypto engine, which
enables AES-NI (Hardware AES) if it is supported by CPU.
Also added a performance benchmark test.

For MP4 files, mp4 parser tries to open and read the same file again
to handle trailing MOOV box.
Open FIFO again may result in packager hang.
Update the code to only attempt to load MOOV for local regular files,
as FIFO and remote files are unseekable anyway.
Fixes#664.

Calculate FRAME-RATE from sample duration as in the DASH solution.
Right now calculated frame-rate may not be accurate in some scenarios,
so we avoid setting the attribute in HLS unless it is more than 30
fps. We will set it unconditionally once it is fixed.

- Parse and extract transfer_characteristics from H264/H265 VUI
parameters.
- Set VIDEO-RANGE attribute in HLS according to HLS specification:
https://tools.ietf.org/html/draft-pantos-hls-rfc8216bis-02#section-4.4.4.2
- Also added an end to end test.

- Add relevant FOURCCs for Dolby Vision.
- Parse DOVIDecoderConfigurationRecord (dvcC, dvvC) to generate
Dolby Vision codec string.
- Propagate Dolby Vision configs (dvcC, dvvC, hvcE) from Demuxer
to Muxer.
- Add a Dolby Vision end to end test.
Support for backward compatibility signaling in DASH and HLS will be
added in a later CL.

Latest version of FFmpeg encodes non standard channel layout, e.g. 5.1(side), in AAC using PCE.
This is now supported with the below changes:
- Allow channel_configuration in ADTS header to be 0, as the cctual channel layout is specified
in PCE.
- Add GetFrameSizeWithoutParsing to determine the frame size before actually parsing the frame.
- Skip and resume later if not the whole frame is available.
- Also ensure that the next frame starts with a proper sync word.
Fixes#598.
- Parses parameter set NAL units in the samples.
- Calculate pixel width and height from track width and height.
Fixes#621, #627.

This is needed for Dolby Vision as Dolby Vision uses NAL unit type 62
to carry private information.
Issue #341.
Change-Id: Ib3f06d8f36ef3d89c33162dd74c012a0c3a805e5
- Define BaseDescriptor and generic read / write operations.
- Define descriptors: ESDescriptor, DecoderConfigDescriptor,
DecoderSpecificInfoDescriptor, SLConfigDescriptor.
DecoderSpecificInfoDescriptor and all other descriptors can now
handle arbitrary length size, not limiting to 64 byte for
DecoderSpecificInfoDescriptor, which was placed to limit
ESDescriptor length size to one byte.
- Now DecoderConfigDescriptor is able to handle reading and writing
of all fields including buffer_size_db, which was not handled
earlier.
Fixes#536.

Add crypto_period_seconds to Widevine key request
When using key rotation with Widevine DRM, a key server has to know
the duration of crypto period to relate generated keys to the media
playback time. This helps the server to provide relevant keys to
a client during license request.
Closes#544.
VLC seems to generate access units with extra AUDs. In #526, the below
sequence is seen:
AUD | SPS | PPS | SPS | PPS | AUD | SEI | SEI | SEI | IDR_SLICE
Previously we exit early when seeing AUD, which results in delayed
processing of the access unit.
The behavior is changed to continue processing the following NAL units
to workaround the content issue.
Closes#526.
