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.

Problem occurs when the media playlists are in a sub-directory under
master playlist. If base_url is not set, segment URL should be
relative to the media playlist.
This only affects fMP4 as TS does not have init segment.

Problem occurs when the media playlists are in a sub-directory under
master playlist. If base_url is not set, media segment URL should be
relative to the media playlist instead of the master playlist.
Also make sure the path separator is "/" in URL instead of "\" on
Windows.

Support generation of fairplay key system tag: "com.apple.streamingkeydelivery" when --pssh

- The master playlist should have the display resolution instead of the
encoded resolution.
- Changed MediaPlaylist to return display resolution.

- Use byte range format if segment_template is not set in MediaInfo.
- Change HlsNotifier::NotifyNewSegment() to take start byte offset.
- Change HlsNotifyMuxerListener to cache the segment information if
MuxerOptions::segment_template is set.

In the original manifest updating process, the file was truncated first
before was written with new contents. There is a small chance that
the web server may read back empty file or incomplete file.
The new code makes the update operation atomic (by writing to a temporary
file first then replace the old file with the temporary file).

- 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.

Resolving TODO in packager/hls/base/master_playlist.cc that asked for
media playlists to be grouped when they are added.
Change-Id: I01c7687400bc74ce45f271d0242d1c3bf3610cf2
The HLS manifests output by the packager did not have the RESOLUTION
attribute on EXT-X-STREAM-INF tags. This change adds the resolution
tag when resolution values are present.

- Add EXT-X-MAP tag for init segment.
- Do not set output field on stream descriptor if not specified on
command line. If it's set (internally) then it gets copied to
MediaInfo that gets passed to the manifest generators.

Before this, HLS output did not contain language information.
Now, media playlists are properly tagged with a language in the
master playlist.

supported in C++11
2. Replace string_as_array with &string[0] which is guaranteed
to work in C++11

- Cannot include PMT for following encrypted segments in the clear lead.
Some players consider them as conflicting codecs.
- Add EXT-X-DISCONTINUITY in front of first EXT-X-KEY to notify that the
codec is switching from e.g. "avc1" to "zavc".

- Remove fields from MuxerOptions. Instead pass them directly to
HlsNotifyMuxerListener.
- Rebase segment names to the master playlist's path where it makes
sense.

- Media Playlist that is non-VERSION 1 must have EXT-X-VERSION.
- Attribute for EXTINF should be CODECS instead of CODEC.
- BANDWIDTH attribute expects bitrate (not bytes per second).
- Removed unnecessary check if MediaInfo has media_info_name, in
SimpleHlsNotifier::NotifyNewStream().

STLValueDeleter.
