style: Use angle-brackets for all internal headers (#1271)
This feeds into efforts to create a working install target.

The order of headers is still funky, and was "fixed" by clang-format,
but in a way that doesn't exactly align with the style guide. Further
cleanup of header order is coming in a follow-up PR.

KongQun Yang 74df8d30cc Exclude short segments from peak bandwidth computation
https://tools.ietf.org/html/rfc8216#section-4.1
The peak segment bit rate of a Media Playlist is the largest bit rate
of any contiguous set of segments whose total duration is between 0.5
and 1.5 times the target duration.

Fixes #498.

KongQun Yang 224b597b48 Support approximate SegmentTimeline
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.

Aaron Vaage 8067fd4818 Made Trick Play A 1:1 Handler
Before the trick play handler would have one input and multiple
outputs. The normal media handler API for adding handlers had to
be ignored when setting-up the trick play handler.

This changes the trick play handler to have one input and one output.
It uses the standard AddHandler method calls. When initialized, the
trick play factor must be provided.

This included a run of 'clang-format' over all edited files.

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.

Fixes #227

Kongqun Yang 80c54a533a Update cmd flags to support static mpd with live profile
- 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

Joey Parrish 3cc86c62b5 Add a stream descriptor field for language.
If a stream has no language metadata, or has the wrong metadata, this
field allows the user to override this on the command-line.

This also maps all specified languages on the command-line to ISO-639-2
tags as required by the MP4 muxer, so that ISO-639-1 tags specified on
the command-line do not cause a DCHECK to fail.
