This changes almost all encrypted tests to use DiffDir. The remaining
un-updated tests are tests that won't match every time.

Change MediaInfo media paths in test output to only use the filename so
that they can be compared between test runs.

iframe playlists will be given a name based on the output name of
the main stream. This is done to ensure unique filenames between
different video output streams.

Instead of using the test file's index in a list to create the output
name, use the original filename and the descriptor.
This caused some problems with file name collisions when some tests
were using the same name. That was fixed by changing the names. This
will go away once they are transitioned to use DiffDir like the other
tests.

This is called when reaching end of the file of the media. The duration

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

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.

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).

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.

This change has the hls master playlist add the text codec string

Updated as many tests as we easily could. The tests that were not updated
all use live manifests or encryption that all require some "help", either
by dealing with times differing or with verifying decryption.

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.

Created end-to-end tests for the segmented webvtt text in HLS. The
text stream is longer than both audio and video, so there are more
text segments than video/audio.

Looks like Safari does not like v0 tenc box.
- Use v1 tenc box for cbcs and cens protection_scheme as required by
CENCv3 spec.
- Set crypt_byte_block and skip_byte_block to 0 for full sample
encryption cbcs and cens.

The old vtt sample data has the header as "WEBVTT FILE" which does

This changes it to "WEBVTT" as described in the WebVTT spec.

- Add empty lines between different types of renditions to improve
readability.
- Group variants with the same audio/text group together, as it is
where the Adaptation occurs.
- Write master playlist after writing media playlists. This makes
more sense and it is also necessary to have the bandwidth of
the last iframe playist segment correctly computed.
- For fMP4, I-Frame segment must include the 'moof' header.
- Fix a problem that hls_iframe_playlist_name is not passed to
MuxerListenerFactory.

If no hls group name is given, we would default to "audio" but as
we are working to support text, this won't make sense to see
GROUP="audio" on a text stream.
Instead default to "default-audio-group" for audio streams. A specific
text default will be added later.

The IV was incorrectly updated across samples.
Created a new cryptor SampleAesEc3Cryptor specially for SAMPLE-AES
EC3 encryption / decryption. The new cryptor uses constant-iv, and
makes sure the IV is reset to the initial value at the beginning
of each audio frame and chained across syncframes within the the
audio frame.
Also added E-AC3 end to end test.

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.

As specified in HLS spec (https://tools.ietf.org/html/rfc8216):
All audio EXT-X-MEDIA tags SHOULD have a CHANNELS attribute. If a
Master Playlist contains two Renditions encoded with the same
codec but a different number of channels, then the CHANNELS
attribute is REQUIRED; otherwise, it is OPTIONAL.

- Remove the TS key rotation not supported check as there is nothing
to be done for key rotation in TS for SAMPLE-AES.
- Fix IV updated problem in new segments even if crypto period does
not change.
- Avoid duplicate EXT-X-KEY tags if it does not change.
- Make EXT-X-DISCONTINUITY-SEQUENCE match with number of removed
EXT-X-DISCONTINUITY.
- Added end to end test for HLS with key rotation.

The HLS manifests output by the packager did not have the RESOLUTION

This addresses playready broken with clear lead = 0.
clear lead != 0 is still broken with playready on Edge. We think it is
likely an Edge bug, which does not support multiple sample entry boxes,
thus does not support clear lead.

- v0 is no longer supported
Change-Id: I189c813d788400beda797eea7da943a83dfa7d79
- 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
