It allows users to override the default language for text tracks.
If not specified, --default_language applies to both audio and text

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.

Keep bundled binutil scripts but not downloading actual binaries by default.
Automatic downloading of binutils has been causing problems for some users:
see #164, #412, #440.
Using bundled binutils helps reduce linking time, but packager codebase is
relatively small, so the gain is not significant.
Local testing shows that the full build time increases from 1m42s to 1m50s, i.e.
an increase of about 8s, or ~8%.
User can still enable the usage of bundled binutils by running
'python src/packager/third_party/binutils/download.py' and set
'linux_use_bundled_binutils' and 'linux_use_bundled_gold' to 1 in GYP_DEFINES.

Configurable with --transport_stream_offset_ms.
This is needed to compensate for possible negative timestamps in
inputs, which could happen on ISO-BMFF with EditLists.
Issue #112.

This flag was designed for two purpose:
- Grouping fragments into subsegments, achieving three level hierarchy:
segment < subsegment < fragment.
- Indicate whether to generate 'sidx' box in media segments (when the
value is set to a negative number).
There are no practical use case for the first purpose. Removing it to
simplify the code and reduce the confusion.
Introduce another flag --generate_sidx_in_media_segments for the second
purpose.

It was implemented to workaround Chromium's DTS

This allows UDP receive buffer size to be increased to avoid potential
packet loss result from receive buffer overrun.
Another related flag is --io_cache_size. buffer_size in UDP options
defines the UDP buffer size of the underlying system while
io_cache_size defines the size of the internal circular buffer managed
by Shaka Packager.

RST only accepts two forms for option argument:
- Begins with a letter and consists of [a-zA-Z0-9_].
- Begins with "<" and ends with ">"; any characters except angle
brackets are allowed internally.
Updated documents to obey the above rule.
Also cleaned up the documents to follow the syntaxes defined in

Packager uses ThreadedIO to write media segments and manifest /
playlists. There was a possibility that media segments write being
delayed and scheduled after updating manifest / playlists.
This CL fixes the race condition.
Also added a note on how segments can be synced to cloud storage to
avoid the race condition during file sync.
Also added a live WebM test.
Fixes#386.

The number of preserved segments outside live window can be
configured using flag --preserved_segments_outside_live_window,
which is default to 50, i.e. 5 minutes for 6s segment.
Note that the segment removal will be disabled if it is set to 0.
Only HLS live playlist and DASH dynamic MPD are affected by this flag.
- Also add end to end tests.
Fixes#223.

It is not always possible to align segment duration to target duration
exactly. For example, for AAC with sampling rate of 44100, there are
always 1024 audio frames per sample, so the sample duration is
1024/44100. For a target duration of 2 seconds, the closest segment
duration would be 1.984 or 2.00533.
This feature allows MPD generator to treat these segments as having
the same duration, thus allows MPD generator to generate less
SegmentTimeline entries and potentially no SegmentTimeline entries
(replaced with SegmentTemplate@duration instead if
--segment_template_constant_duration flag is enabled).
Under flag --allow_approximate_segment_timeline. Disabled by default.
Fixes#330.

UTCTiming schemeIdUri and value pairs can be provided to packager using
--utc_timings flag. It should be comma separated list of
schemeIdUri=value pairs.
Note that urn:mpeg:dash:utc:direct:2014 scheme is not supported as it
requires the MPD to be dynamically generated on the fly when MPD is
served to client.
Fixes#311.

The keys can be specified in --keys option, with the form of
label=<label>:key_id=<32-digit hex string>:key=<32-digit hex string>,label=...
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.

'availability_time_offset' is not an attribute in MPD specification,
but used to calculate availability_start_time to adjust segment
availability time. A similar effect can be achieved with standard
blessed suggested_presentation_delay flag.
If suggested_presentation_delay is not set, player is expected to
choose a suitable value.

Profiling can be enabled by setting profiling=1 in gyp, e.g.
GYP_DEFINES="profiling=1" gclient runhooks
To turn on heap profiling, use the HEAPPROFILE environment variable
to specify a filename for the heap profile dump, e.g.
HEAPPROFILE=/tmp/heapprofile out/Release/packager ...
To turn on cpu profiling, use the CPUPROFILE environment variable
to specify a filename for the cpu profile dump, e.g.
CPUPROFILE=/tmp/cpuprofile out/Release/packager ...
Note that profiling may not work for debug builds, so use release
build if possible.
See docs/linux_profiling.md for details.
This change will help identify and resolve problem behind Issue #61.
