KongQun Yang 1223694249 Do not force earliest_presentation_time to 0 for VOD
Instead, the actual earliest presentation time is used except for
the first segment if there is an offset between presentation time
(pts) and decoding time (dts).

Chrome (as of v66) reports dts instead of pts in buffered ranges in
MSE API. To avoid breaking Chrome, the earliest_presentation_time
of the first segment is set to its dts as Chrome does not like negative
values for
  adjusted dts = dts + Period@start (0 for the first period)
                 - presentationTimeOffset (earliest_presentation_time).

Fixes #303.

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

Jacob Trimble 96abd90ca2 Only encrypt video slice NAL units.
For non-video slices, the data is not encrypted.  This also skips the
frame headers for H.264; support for H.265 will be added later.
