Removed the code for NALU splitting in the H.264 parser and moved
it to its own class. Also added support for length-prefixed
NALU splitting for use with the encrypting fragmenter.

Parse channel layout value from dec3 box. Pass it through audio stream
info. MPD builder forms audio channel configuration to signal ec-3
codec.
Specs: 1) ETSI TS 102 366 V1.3.1 Digital Audio Compression (AC-3,
Enhanced AC-3) Standard E.1.3.1.8.
2) DASH-IF Interoperability Points v3.0 9.2.1.2.

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.

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.
Fixes#71

- 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

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.

- 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
Change-Id: I69dc97088aa38c94c6d37fdbcf3d9cfc942a3df6
- 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.

Also update the code to generate CompressorName in VideoSampleEntry
for both AVC1 and various VP codecs.
Change-Id: I2355f8008a72806e852aa1ec6c80e9141b97d963
- 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.

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).
Issue: 39
Change-Id: Id55c5acf245bee3f4e66302b2042eb7d9c488c19
- Because MpdBuilder no longer sets ContentProtection, live was broken.
- For key-rotation, <cenc:pssh> element is updated.

This fixes a circular dependency of media_base depends on filter and
filter depends on media_base.
Also added code to extract sar in WvmMediaParser if it is not yet
extracted when setting extra_data.
Change-Id: I1b5aef2444e4134c9b6663911ac5e5c4c220404a
- Width/Height in tkhd box should be display resolution instead of
coded resolution.
- pasp was not generated earlier.
- Assuming SAR as 1:1 if it failed to be extracted successfully.
- Also update test files for mp4_media_parser_unittest.
This fixes Issue #35.

The segment duration was not reset after segment was finalized. It
was reset after adding one sample. This new sample was added to the
new fragment but was not recorded in the new segment, which resulted
in off-by-one error in the segment generation.
Change-Id: I1f9e00591be6b897773bf6caf94409b4bcd2277f
- The UUID and DRM name can be fetched from KeySource.
- Add ProtectedContent message to MediaInfo. The message contains basic
information for the protected content, such as the default key ID for
the content.
- The message is required to separate Representations with different
content protection information into different AdaptationSets.
Change-Id: Ib9dc834ae0abf93b7ca0acdf52a865b1394a4816
- Added logic to container parsers to extract pixel width and height.
- If the container doesn't contain the pixel width and height of the
stream and the stream is H264, this parses the SPS to get the
sar_width and sar_height.
- If extracted sar_width and sar_height are 0s then they imply 1s.
- Add hb2_v_frag.mp4 for test media. This does not have a
'pasp' box and has sar_width = 8 sar_height = 9.
Change-Id: I4a06ce95582547bec19adb7905e7612c5a1f359e
- The fields used to be repeated but there is no use case at the moment.
- DASH IOP explicitly disallows segments with multiple tracks.
Change-Id: Ia0af2048210c546dfaa178735605a81052ea1123
- Get the first sample duration in Segmenter.
- Pass the value all the way to Representation thru MuxerListener.
