KongQun Yang 32e3ff3e25 Set default --segment_duration to 6 seconds
This is recommended by Apple and other content providers:
https://apple.co/2uTTAc4

- Set default --clear_lead to 12 seconds, i.e. about 2 segments.
- Set default --fragment_duration to 0 so fragment (sub-segment) is not
  generated by default.

KongQun Yang 51d39d96a1 Add offset to tranport streams (MPEG2-TS, HLS Packed Audio)
Configurable with --transport_stream_offset_ms.

This is needed to compensate for possible negative timestamps in
inputs, which could happen on ISO-BMFF with EditLists.

Issue #112.

KongQun Yang 1742e03471 Drepcate --num_subsegments_per_sidx
This flag was designed for two purpose:
- Grouping fragments into subsegments, achieving three level hierarchy:
  segment < subsegment < fragment.
- Indicate whether to generate 'sidx' box in media segments (when the
  value is set to a negative number).

There are no practical use case for the first purpose. Removing it to
simplify the code and reduce the confusion.

Introduce another flag --generate_sidx_in_media_segments for the second
purpose.

KongQun Yang f089d1d0d4 Deprecate --mp4_use_decoding_timestamp_in_timeline
It was implemented to workaround Chromium's DTS
https://crbug.com/398130, but the workaround does not really work in
all situations.

Remove it now as we already have another workaround available.

Kongqun Yang d007ddf20b [MP4] Make outputs CMAF compatible
- Added flag --mp4_include_pssh_in_stream, default to true. If it is
  set to false, the encrypted mp4 stream will not include pssh.
- Align BytesOfProtectedData to multiple of 16 bytes for cenc.
- Set TrackHeader flag to kTrackEnabled | kTrackInMovie |
                          kTrackInPreview
- Move mvex to after trak, required by HLS
- Add cmfc/cmfs compatible brands except for avc3/hev1, where CMAF
  requires single initialization switching set which is not supported.
- Set duration to 0 in tkhd, mdhd, mvhd.

Also updated major_brand and compatible brands:
- Set major_brand to isom (iso-bmff media file format) and made dash
  a compatible brand
- Replaced compatible brand iso6 with iso8 since we use sthd for text
  tracks

Fixes b/36278260

Kongqun Yang 80c54a533a Update cmd flags to support static mpd with live profile
- Deprecated command line flags --profile and --single_segment.
  'segment_template' in stream descriptors implies live profile
  and non-single segment.
- Added flag --generate_static_mpd_for_live_profile to generate
  static mpd for live profile; if not set, dynamic mpd will be
  generated.

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.
