Aaron Vaage ec83d8a73a Implement MsToWebVTTTimestamp
Implemented the other end of the webvtt timestamp parsing as it will
be needed when we write out WebVtt files. Also changed the name of
the parse function to be more inline with the writing function.

Aaron Vaage e605203fa7 Added Origin Handler
Created a handler called OriginHandler that can be used by the Job class
(previously called RemuxJob). Origin handlers represent the start (or
origin) of a pipeline (chain of handlers).

Rintaro Kuroiwa 0dfdace280 Change MuxerListener::OnMediaEnd to take ranges
- Changed OnMediaEnd() to take (sub)segment ranges.
- Define a structure to pass the ranges.
- This requires muxers to "cache" the segment ranges but in most cases,
  they already do it, e.g. 'sidx' for mp4.

KongQun Yang d9e7e2f1d0 Generate two sample entries only if there is clear lead
This addresses playready broken with clear lead = 0.

clear lead != 0 is still broken with playready on Edge. We think it is
likely an Edge bug, which does not support multiple sample entry boxes,
thus does not support clear lead.

- 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

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 24ba12c18e Remove escape parameter in NalUnitToByteStreamConverter
The spec actually requires all NAL units to be escaped, so there
is no need to escape it again.

NAL byte stream is one demarcation method; NAL unit stream is another
demarcation method. Regardless of the demarcation method used, the
requirement for NAL unit is the same. See the last paragraph of
7.4.1 NAL unit semantics on the requirement on emulation prevention bytes.

Kongqun Yang c223bc9144 Keep slice data partition NALs in clear
CENCv3 recommends only encrypting video data in slice NALs. Slice
data partition NALs should not be encrypted.

In the code, differentiate is_vcl and is_video_slice. They are the
same for H265; for H264, vcl NALs include slice data partition NALs
but video_slice NALs do not.
