Aaron Vaage b0edec8c40 Changed Text Segmenter to output segment info last
To better align with the Chunking Handler, the Text Segmenter
now outputs the SegmentInfo at the end of the segment rather
than the start.

Aaron Vaage ab19082c20 WebVtt To MP4 Handler
Implemented a MediaHandler that takes text samples and creates
media samples. The data in each media sample is the MP4 box for
non-overlapping cues.

As per WebVtt in Mp4, all cues must be non-overlapping. This handler
takes care of grouping and dividing cues.

Aaron Vaage c03c447e0b Created WebVtt Segmenter
This change creates the webvtt segmenter which will be used for
segmented text webvtt for HLS. It takes a stream of text samples
and injects segment info messages based on the segment duration.

It is possible for samples to extend between segments, if so the
sample will appear twice (once in each segment).

Aaron Vaage 4dcfe413f5 WebVTT Parser
Took the WebVTT Media Parser and created the WebVTT Parser
that will take in a file and output a stream of cues that
will later be passed to another Media Handler that takes in
cues and chunks them.

KongQun Yang 8e96dd3b37 Address gcc build failures in some platforms
Seeing some failures on some platforms when compiled with clang
disabled:
  GYP_DEFINES="clang=0" gclient runhooks

Several changes to make it work:
1. Mark packager code with packager_code=1 in GYP definitions.
2. Disable a few checks in non-packager code, which we do not have
   direct control: dangling-else, deprecated-declarations,
                   unused-function
3. Fix the relevant errors in packager code.
4. Revert HAVE_STROPTS_H in curl config which is not available in
   all linux distributions.

Aaron Vaage ec83d8a73a Implement MsToWebVTTTimestamp
Implemented the other end of the webvtt timestamp parsing as it will
be needed when we write out WebVtt files. Also changed the name of
the parse function to be more inline with the writing function.

Aaron Vaage e605203fa7 Added Origin Handler
Created a handler called OriginHandler that can be used by the Job class
(previously called RemuxJob). Origin handlers represent the start (or
origin) of a pipeline (chain of handlers).

Moved all the timestamp parsing code into its own class with its
own unit tests. This is to make testing easier.

Rintaro Kuroiwa a3ce51785a Make WebVttMediaParser use WebVttSampleConverter
- WebVttMediaParser uses WebVttSampleConverter to generate non
  overlapping media samples.
- The media samples contains ISO BMFF boxes.
- Add kCodecWebVtt to signal that the media is webvtt and
  the samples will be in ISO BMFF boxes.

Jacob Trimble abb1abf5c5 Rename StreamInfo::extra_data to codec_config.
Since the |extra_data| field contains codec-specific configuration
data, it makes sense to call it |codec_config|.

Anders Hasselqvist db7bebe3fa MacOSX: Solve libbase.a conflict link error
On Linux the generated ninja files use path/libbase.a as target name.
In the Mac ninja file the target is just libbase.a.
As we have two libbase.a (base/base.gyp and media/base/media_base.gyp) the linking stage fails to include both libs.

Solve by renaming media_base.gyp's base target to media_base

KongQun Yang 2c3aed4842 Handle possible NewSampleEvent before ParserInitEvent
For WebM contents, it is possible that we may receive some NewSampleEvent
before receiving ParserInitEvent. This is because init event is fired
after analyzing a video block which could come after an audio block.

Also modified Flush() function to return a bool to indicate whether the
the flush is successful and whether the samples are handled correctly.

And added macro to ensure Flush() and Parse() results are handled.

Fixes #71
