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.

If the user has the GPAC MP4 tools installed, this will use that to
provide a better, text-based diff of the MP4 files. This makes looking
at test failures much better than just "binary files differ".

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.

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.

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.

HLS uses the EXT-X-MEDIA-SEQUENCE tag at the start of a live playlist in
order to specify the first segment sequence number. This is because any
live playlist have a limited number of segments, and they also keep
updating with new segments while removing old ones. When a player refreshes
the playlist, this information is important for keeping track of segments
positions.
When the packager starts, it naturally starts this count from zero. However,
there are many situations where the packager may be restarted, without this
meaning starting this value from zero (but continuing a previous sequence).
The most common situations are problems in the encoder feeding the packager.
With those cases in mind, this parameter allows to set the initial
EXT-X-MEDIA-SEQUENCE value. This way, it's possible to continue the sequence
number from previous packager run.
Closes#691.
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.

Although FRAME-RATE is optional per HLS specification, but per HLS
Authoring Specification for Apple Devices (https://apple.co/30n90DC):
Each EXT-X-STREAM-INF tag MUST have a FRAME-RATE attribute.
Also, iOS and TVos refuse to play the content if VIDEO-RANGE is
present but FRAME-RATE is missing.

- 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.
Fixes#632.

- 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.

Add dash_accessibilities stream descriptor, which is a semi-colon

Add dash_roles stream descriptor, which is a semi-colon separated

We have logics in bandwidth calculation to ignore segments that is
smaller than half of target duration. The logic does not have any
effect right now as the target duration in mpd/hls params is always
zero.
This change will set target duration in mpd/hls params, thus it can fix
part of issue #581 as the last segment which is less than half of
target duration.

Addresses binary/str conversion problems like
'can't use a string pattern on a bytes-like object'.
With this change, packager_test.py will work with any version of python
after python2.5.

Generate an audio only master playlist if there are no videos and

We do not support mixing audio only EXT-X-STREAM-INF with video

Only Marlin Adaptive Streaming Specification – Simple Profile is
supported.
Two additional updates:
- Remove FairPlay ContentProtection element from DASH mpd as FairPlay
does not define a signaling in DASH.
- Updated end to end test to include all DRMs we support.
Closes#381.
Change-Id: Id12269b471ea34983b782cbd92f687332292ef59
This was introduced earlier to indicate FairPlay protection system. But
in fact, it is sufficient to just use the system id for the indication.
- Also updated various parts of the pipeline to support empty PSSH.
- Added an additional FairPlay end to end test using fMP4.

Note that TTML in ISO-BMFF is not supported yet.
Also updated packager_test.py:

- Computed output extension from input extension unless output_format
is specified.

The time for the previous segment was used when generating the segment
name. This resulted in the first segment being overwritten and
mismatching manifest and media files. It led to playback problems.

The VP9 level is computed when the container is missing a codec config
or if the level is missing from the codec config.
This fixes VP9 in ISO-BMFF files generated by FFmpeg v4.0.2 or earlier
which does not have level set in the codec config.
Fixes#469.

And AOM AV1 codec mapping in Matroska/WebM at
https://github.com/Matroska-Org/matroska-specification/blob/av1-mappin/codec/av1.md
Note that AV1 specific boxes are not supported in this CL, i.e.
AV1 Forward Key Frame sample group entry 'av1f', AV1 Multi-Frame
sample group entry 'av1m' etc are not supported. These boxes are optional.
We will add support later if they are useful to the clients / players.
Encryption is not supported yet.
