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.

Now outputs cenc:default_KID attributes on all ContentProtection
elements for non-MP4 streams. For MP4 streams, it will still output
the default ContentProtection element.

- Also refactor decryptor management code out of mp4_media_parser.cc
- Move decryptor managment logic to DecryptorSource class to make it
available for webm as well
- Remove data_offset member from DecryptConfig which is not useful
- Add widevine_pssh_data.proto file

- dts was not set earlier, although for WebM, we could assume that
dts is the same as pts.
- Calculate block duration with the difference with the next block
if duration is not encoded, even if track default_duration is set.
- Use track default_duration as a duration estimate for the last
block.
- This also removes opus duration computation from encoded data.

This does not support key-rotation and will give an error. This is
because WebM does not have a way to indicate a change in key ID using
media segments.

- Check if 'output_dir=' is already defined in GYP_GENERATOR_FLAGS
before appending the one generated in the script.
- Reusing out/ with different GYP_DEFINES causes everything to rebuild.
- This change allows the user to use different directories for different
GYP_DEFINES; it can make sanity checking faster for different
GYP_DEFINES.

- From DASH spec 2014, MPD@publishTime and Period@id are required for
'dynamic' MPD.
- Period@id is always set to "0".
- MPD@publishTime is set to the time when the MPD is output.

Added packager tests for WebM audio. Also now only outputs the
language if it's not empty. Fixed the packager tests for that.

ThreadedIoFile spawns a new thread for every new file. Thread
information is stored for tracking purpose by base::tracked_objects.
The tracking object remains even if the thread itself is destroyed.
This results in memory usage increased by a couple of bytes for every
new segment created in live mode (new segments spawns new threads).
Use WorkerPool instead to avoid spawning new threads.
Fixes Issue #61.

For mp4 outputs, a metadata box with version information is added to
moov box.
For mpd outputs, a text comment with version information is added in
the beginning of mpd file.

- Another minor change in segmenter_test_base: scoped_refptr can
be passed by value, remove ".Pass".

* Changed Segmenters to accept StreamInfo rather than MediaStream
to help in testing.
* Changed MemoryFile behavior to mirror local file:
* Read non-existent file is an error.
* Write deletes any existing file.
* Fixed a bug in SingleSegmentSegmenter.

Javascript/JSON does not support int64_t or unsigned numbers. asset_id,
if greater than 0x80000000 will be converted to negative number. Use
double to represent asset_id instead as 32-bit integer can be lossless
represented using double.

- Replaced urn:mpeg:DASH:schema:MPD:2011 with
urn:mpeg:dash:schema:mpd:2011. The former is from the old spec.
- Replaced the MPD schema with the latest one.
- Fixed subSegmentAlignment typo with subsegmentAlignment.

This can be used for unit tests to reduce the need for temporary
files. A MemoryFile acts the same as any other File object, but
stores the contents in memory. The memory pointer can be accessed
directly. A file with the 'memory://' prefix will be a memory file.

- Parse vp9 bitstream to get vpx codec configuration
- Add subsample encryption for vp9
- Also fixed a bug in VP9 parser if segmentation update_map is enabled

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.

- Add Box::WriteHeader and Box::HeaderSize methods. The concrete
box implementations should not need care about whether it is a
Box or FullBox normally.
- Rename Box::ReadWrite to Box::ReadWriteInternal to make it clear
that it is an internal methods. Make it private so it cannot be
incorrectly called in box implementions.
- Make an internal implementation of ComputeSizeInternal to compute
box size. |atom_size| is updated in ComputeSize, which wraps
ComputeSizeInternal.

Added two stream descriptors that are both used to tell the output
format. If it is not given, the packager will use the output file
extension to determine the output format.

* Added WebM muxer that supports both single and multi-segment modes.
* WebM muxer supports MPD generation.
* Enabled WebM muxer and demuxer in packager.
