This will move ContentProtection element from Representation
to AdaptationSet.
Shaka Player already supports AdaptationSet switching
urn:mpeg:dash:adaptation-set-switching:2016;
ExoPlayer does not support it yet. Filed
https://github.com/google/ExoPlayer/issues/2431 to track the issue.
(ExoPlayer does not like having ContentProtection in Representation
anyway)
Closes b/34691105

- Deprecated command line flags --profile and --single_segment.
'segment_template' in stream descriptors implies live profile
and non-single segment.
- Added flag --generate_static_mpd_for_live_profile to generate
static mpd for live profile; if not set, dynamic mpd will be
generated.
Close#142
Change-Id: I78879297ed118f0f246c4753a16ad125bd6b5e4f
- Added two new fields in MpdOptions: dash_profile and mpd_type
- Updated MpdBuilder to support LiveProfile with static mpd
- Command line arguments will be updated in the next CL

Current mechanism of using AdaptationSet @group is not spec compliant.
The spec compliant mechanism is to use supplemental descriptor with
schemeIdUri: urn:mpeg:dash:adaptation-set-switching:2016 as specified
in ISO/IEC 23009-1:2014/Amd.4:2016.

- nalu_data points to the beginning of the nalu, instead of
beginning of the slice header which excluded the nalu
header.
- nalu_size is the size of the whole nalu.
- header_bit_size calculation is corrected. The size used to exclude
emulation prevention bytes.

- If OnEncryptionStart() is called OnMediaStart(), someone should be
calling NotifyEncrytionStart().

Three options are supported right now:
- reuse=1|0
Allow or disallow reusing UDP sockets. Default 0.
- interface=a.b.c.d
Address of the interface over which to receive UDP multicast
streams.
- timeout=microseconds
Timeout in microseconds. Default to unlimited.
A UDP url should be of the form udp://ip:port[?options], here
is an example:
udp://224.1.2.30:88?reuse=1&interface=10.11.12.13&timeout=12345
Also deprecate --udp_interface_address flag in favor udp options.

1. Allow encryption pattern of 0:0, which is treated as 1:0;
2. Remove the special handling of pattern 1:0 in pattern cryptor
which may not always be correct;
3. Allow senc/saio/saiz boxes to be absent.

The original code creates temporary file in the current directory,
which may not always be writable.

- Also import the version of the protobuf bundled in packager first,
this avoids importing the installed version of the protobuf, which
may not be compatible with this script.

Cues used to be generated in the end of the file; if http range
request is not supported, clients have to download the whole
file to get to the cues.
This CL updated TwoPassSingleSegmentSegmenter to write cues
after writing webm header.
This CL also updates libwebm dependency to latest.

The original code accumulates sample durations in seconds (double)
and then generates new segment / cluster by comparing the accumulated
value with configured value.
There may be loss of precision when accumulating values in double.
For example, with a GOP of 96 frames and frame rate of 24 fps; the
accumulated frame duration for 96 frames is 3.999999999999, which is
very close to 4.0 but not 4.0. Problem would arise if segment
duration is set to 4. The created segments would have a duration of
8 seconds instead of 4 seconds.
The new code accumulates sample durations in uint64_t relative to
input time scale; the configured segment duration will be converted to
timescale for comparison. This avoids loss of precision.

Setting this flag will tag any matching tracks with kRoleMain.
The player will then know which tracks should be default when there
is not a language match.

Language tags can have subtags, such as "por-BR". While the base tag
should be 3 characters, the entire tag can be longer. Rather than
parse out the base tag and check that it is size 3 without the subtag,
we can just trust the ISO tag converter to do the right thing.

Some subtitle files use .webvtt instead of .vtt, probably because
ffmpeg uses -f webvtt when converting from some other format.

- Also regenerated test content to insert an iframe every one
second: ffmpeg -i source.webm -auto-alt-ref 1 -g 30 out.webm
This makes sure the content is actually encrypted with one
second clear lead in end to end test.

1. Add Windows support in README.
2. Add a useful links section in README.
3. Set line length to 80 characters in README; if exceeded,
will wrap to a new line. This won't affect the presentation
for the markdown.
4. Include the content of Chromium.License in License file.

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

The current behavior of logging to a file in the same directory

to that directory.

In H264, there may be multiple consecutive video slice NAL units
in the same frame. The original code assigns a new access unit
for every video slice NAL unit, which is incorrect.

Mimic iso-bmff behavior: either all the samples in a segment are encrypted
