Aaron Vaage 16eff80497 Made StreamData Have Const Pointers
In prep for changes to Trick Play, we want to make all messages
copy on write so that if the same message is sent to multiple
handlers, it is not possible for one handler to change the data
another handler is using.

Kongqun Yang 277c5b23c0 Allow generating avc3 / hev1 from TS and Wvm files
Added a flag --strip_parameter_set_nalus. When enabled, parameter
set NAL units, SPS/PPS for H264 and SPS/PPS/VPS for H265, are stripped
from frames when converting NAL byte stream (AnnexB stream) to NAL
unit stream, which generates avc1/hvc1; otherwise they are not
stripped, and avc3/hev1 is generated.

Parameter set NAL units should not be stripped if they are varying
in the frames otherwise the frames may fail to be decoded.

The flag is enabled by default as we don't usually see varying
SPS/PPS/VPS and it is more space efficient with them stripped.

Set --strip_parameter_set_nalus=false to disable the flag if there
are varying SPS/PPS/VPS in the frames. This addresses #206.

Kongqun Yang c3d1dc1733 Deprecate STLDeleter and string_as_array
1. Replace STLDeleter with unique_ptr in container, which is
   supported in C++11
2. Replace string_as_array with &string[0] which is guaranteed
   to work in C++11

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|.

KongQun Yang 8c202047fb Make edash-packager outputs predictable for testing
- 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.

Kongqun Yang 2a95367dd4 Move SAR extraction out of video_stream_info.cc
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.

Kongqun Yang e5b6096857 Generate tkhd and pasp boxes properly with non-square pixels
- 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.

Rintaro Kuroiwa c3c971ebd9 Add pixel_{width,height} to VideoStreamInfo
- 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.

KongQun Yang 15ae26e12f Modify include headers to have "packager" in the path
This is a follow up to previous CL.

Generated using command:
find {media,app,mpd} -type f -exec sed -r -i 's/#include "(.*)"/#include
"packager\/\1"/' {} \;

common.gypi and mpd.gyp are also modified to take the path change into
consideration.
