Parse channel layout value from dec3 box. Pass it through audio stream
info. MPD builder forms audio channel configuration to signal ec-3
codec.

Enhanced AC-3) Standard E.1.3.1.8.

Before this change, the media file will fail to be parsed if it contains
non-wvtt text streams. This change allows demuxing of video and audio
streams in these media files even though the text stream is ignored.
Fixes#74.

This also changes the way frames are written in the WebM muxer. Now,
frames are stored and written on the next call to AddSample. So each
call to AddSample will write the previous frame. This is needed to
determine whether the given frame is the last one in the cluster.

Create a new MacOSX configuration for curl:
- Add a curl_config.h created on MacOSX
- Add a find_curl_ca_bundle.sh that searches default folder from Homebrew and MacPorts for a ca bundle.
To find the files either install OpenSSL from Homebrew or MacPorts, or Curl from MacPorts.
When generating ninja files we end up with two libwebm targets.
packager/media/formats/webm/webm.gyp:webm -> becomes target libwebm
packager/third_party/libwebm/libwebm.gyp:libwebm -> becomes target libwebm
Solve this conflict by renaming libwebm.gyp:libwebm to mkvmuxer.
There is a target name conflict between packager/base/base.gyp:run_all_unittests and
media_test.gyp:run_all_unittests. Change to media_test.gyp:run_tests_with_atexit_manager to
resolve the conflict.
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
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.

'dynamic' MPD.
- Period@id is always set to "0".
- MPD@publishTime is set to the time when the MPD is output.

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.

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.

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.

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.
Change-Id: I3fbcf8c527581b676d9d13f1ac1dd798da7c4d5f
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

locks, removing locks from MpdBuilder.

- Added factory methods for creating Representation and AdaptationSet in
tests.
- Since most tests only needed access to the constructors for
Representation and AdaptationSet, instead of using
FRIEND_TEST_ALL_PREFIXES() for each test case, added factory methods
on the test class.
- Check the 'frameRate' attribute in
CommonMpbBuilderTest.SetSampleDuration.

- Neither live with or without key rotation did not output the right
result.
- No key rotation: did not produce any ContentProtection element.
- With key rotation: did not have DRM specific ContentProtection.
- To get key rotation working with shaka player, <cenc:pssh> elements
are removed.
Change-Id: I1f34d303ae1f3ea81820e3368ab66b8420498372
- Added --iv to inject iv for fixed key encryption.
- Added support for key rotation in fixed key encryption.
- Added --use_fake_clock_for_muxer to set timestamp to 0 in the output.
Also updates stream info dump message:
- Modified pixel_width: %d\n pixel_height: %d to pixel aspect ratio: %d:%d
- Removed language from video stream info.
These flags should only be used for testing.
Change-Id: Iedf8d6d6492226219f49fe44d932645f557010e4
- ContentProtection elements were missing when using MpdWriter,
therefore mpd_generator also did not generate ContentProtection.
- MpdWriter uses MpdNotifier now, instead of directly using MpdBuiler.
- Add mock_mpd_notifier.{h,cc} to be shared by several tests.

Cropping is necessary if width/height are not exactly disivible by 16 due
to 16x16 macroblock size.
The width and height fields in VisualSampleEntry must correctly document
the cropped frame dimentions (visual presentation size) of the AVC stream
that is described by that entry.
Also fixes width/height in input mp4 and wvm streams if the values in
VisualSampleEntry / metadata do not match with the values in
AVCDecoderConfigurationRecord (SPS).

write out the MPD.
