sylt bfe302bd5c Add support for skip_encryption stream descriptor (#219)
This option makes it possible to control encryption for specific streams,
e.g. for audio and video separately.

Haoming Chen da8877d8a2 Rename trick play rate to trick play factor.
- Add a "tpf" abbreviation in stream descriptor for

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.

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

- Tracks other than video are protected using whole-block full-sample
  encryption as specified in ISO/IEC 23001-7:2016(E) 9.7, which is
  equivalent to a pattern of 1:0. This is different to the non pattern
  encryption counterparts.
- Also updated the code to allow the existence of other protection
  schemes in the original content, which will simply be ignored.
- The internal cryptor used by AesPatternCryptor should not use
  constant iv, add a DCHECK for that.
- Optimize AesPatternCryptor handling on the special pattern 1:0.
