Aaron Vaage 7dd88ca5b2 Create CheckLiveTestResults
Created a method to compare test output for live tests. This wraps
CheckTestResults but first replaces the times that would diff between
manifests.

Aaron Vaage 74c53239dd Updated Nested Directories Test
This require a change to the update gold method as it would not
create nested directories. Instead it deletes the old directory
and copies the whole new directory over. This made the code simplier
and far-less error prone.

Aaron Vaage 4ace2754fd Avoid Full Path until Needed in packager_test.py
To make working with file names easier in packager_test.py _GetStream
the full path is not created until needed so that multiple paths can
use the same root filename.

Aaron Vaage cd16e95d79 Make All Output Filenames Similar
Changed all output file names (not paths) to follow the pattern that
any qualifier (e.g. trick play) will be join the current name using '-'
but will use '_' within itself (e.g. trick_play_1).

KongQun Yang ee9b7f6392 Calculate presentationTimeOffset and Period@duration from segments
Prefer timestamps from Video AdaptationSets if available - this avoids
possible video playback jitters due to gaps.

presentationTimeOffset is not applied to the first period as it may in
negative dts which Chrome does not like: https://crbug.com/398141.

It is safe to apply to subsequent periods as the actual offset applied
takes Period@start into consideration:

    offset = Period@start - presentationTimeOffset

The result timestamp with offset applied is close to Period@start, so
it is unlikely to result in a negative dts value.

Closes b/73899306.

KongQun Yang b81b832522 Create GetStream
Created GetStream, a function used to get the stream descriptor for a
single stream. This allows for finer control over the stream compared
to the batch GetStreams.

Added "trick_play_factor" to GetStream so that the trick play factor
did not have to be added the stream descriptor value and "injected"
into the stream.

Aaron Vaage 393f989839 Create DiffDir in packager_test.py
Created a method to diff the output dir against the golden copy
of the output dir. The goal with this is to simplify our end-to-end
test structure by removing the need to track the output files within
the test runner.

With all the golden output in one directory, this makes it easier to
setup end-to-end tests and even allows the golden files to be playable.

This should not affect the repo size too much as duplicate files will
only be stored in the git object store once.

Tests will migrate to this in separate CLs.

KongQun Yang 32d26094ba [HLS] Support AUTOSELECT and DEFAULT in EXT-X-MEDIA
According to HLS spec: https://goo.gl/MiqjNd 4.3.4.1.1. Rendition Groups
- A Group MUST NOT have more than one member with a DEFAULT attribute of
  YES.
- Each EXT-X-MEDIA tag with an AUTOSELECT=YES attribute SHOULD have a
  combination of LANGUAGE[RFC5646], ASSOC-LANGUAGE, FORCED, and
  CHARACTERISTICS attributes that is distinct from those of other
  AUTOSELECT=YES members of its Group.

We tag the first rendition with a particular language in an audio group
with 'AUTOSELECT'; it is tagged with 'DEFAULT' too if the language
matches --default_language.

There can be multiple "label=..." block. The DRM label can be one
of "AUDIO, SD, HD, UHD1, UHD2" or a custom label.

Mark --key and --key_id as deprecated. We can achieve the same result
with --keys=label=:key_id=<key_id>:key=<key>.

Also add a new optional field in stream descriptor: drm_label, which
is used to overwrite the internally generated DRM label for the stream.
If not provided, the DRM label is generated automatically based on
audio/video information, e.g. resolution.

Code changes:
- Merged RawKeyEncryptionParams and RawKeyDecryptionParams into
  RawKeyParams.
- Make FixedKeySource accepts RawKeyParams as input.

KongQun Yang 05a5a41969 Support generation of libpackager.so (shared_library)
Shared libpackager can be built by setting libpackager_type to
shared_library, e.g.

GYP_DEFINES='libpackager_type=shared_library' gclient runhooks
ninja -C out/Debug

will generate libpackager.so in out/Debug/lib directory.

Here is a few other changes to make shared_library builds and
tests pass:

- Add several test parameters to packager.h, which is needed for
  testing.
- Create a protoc.gypi from build/protoc.gypi but depending on
  protobuf_full_do_not_use instead of protobuf_lite, since we need
  protobuf_full_do_not_use for text parsing and generation of media
  info proto. Somehow shared_library build does not allow mixed use
  of protobuf_full_do_not_use and protobuf_lite.
- Remove the use of LazyInstance in version/version.cc and use static
  variable directly. This is because LazyInstance needs AtExitManager
  which may not be easy to setup when calling GetVersion.
- Allow skipping testPackageWvmInputWithoutStrippingParameterSetNalus
  with flag --shared_library, which is needed as shared_library build
  does not support --strip_parameter_set_nalus flag yet.

Kongqun Yang d007ddf20b [MP4] Make outputs CMAF compatible
- Added flag --mp4_include_pssh_in_stream, default to true. If it is
  set to false, the encrypted mp4 stream will not include pssh.
- Align BytesOfProtectedData to multiple of 16 bytes for cenc.
- Set TrackHeader flag to kTrackEnabled | kTrackInMovie |
                          kTrackInPreview
- Move mvex to after trak, required by HLS
- Add cmfc/cmfs compatible brands except for avc3/hev1, where CMAF
  requires single initialization switching set which is not supported.
- Set duration to 0 in tkhd, mdhd, mvhd.

Also updated major_brand and compatible brands:
- Set major_brand to isom (iso-bmff media file format) and made dash
  a compatible brand
- Replaced compatible brand iso6 with iso8 since we use sthd for text
  tracks
