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 55050fe6b5 [Ad Insertion] Avoid adjusting EPT except for the first file
EPT (earliest presentation time) may be adjusted not to be lower than
the decoding timestamp (dts), but the adjustment should only be done
on the first file when there is one file per Representation per Period.
The second file and onwards should not be adjusted otherwise a GAP
would be created.

Aaron Vaage cf3fc61fbe Fix incorrect data_reference_index in TextSampleEntry
In the text sample box (for mp4) there was a value called
"data_reference_index" that was never initialized. This meant
that it took on various values can caused different results
between runs.

KongQun Yang 734b4161f8 Ignore unsupported audio codec in the source content
Instead of failing immediately, ignore unsupported audio codec when

source file. This allows the supported streams to be packaged.

KongQun Yang b5a73fc1d5 Refactor ProtectionSystemSpecificInfo class to struct
This is in preparation of supporting entitlement license API, where
common encryption server may return concatenated PSSHs directly.

Refactored ProtectionSystemSpecificInfo into a struct containing
concatenated PSSHs. This will make it easier to pass PSSHs around.

Also, most of the time, users of ProtectionSystemSpecificInfo do
not care what is in PSSH; so moved PSSH box parsing and building out
of ProtectionSystemSpecificInfo.

KongQun Yang 2d919b5a31 Fix potential partial DASH segments during live packaging
Packager uses ThreadedIO to write media segments and manifest /
playlists. There was a possibility that media segments write being
delayed and scheduled after updating manifest / playlists.

This CL fixes the race condition.

Also added a note on how segments can be synced to cloud storage to
avoid the race condition during file sync.

Also added a live WebM test.

Fixes #386.

KongQun Yang 772aa7c93f 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).

2. Disable a few checks in non-packager code, which we do not have
   direct control: dangling-else, deprecated-declarations,
                   unused-function

KongQun Yang 92e1e39868 Update MediaSample to avoid redundent copying
Use std::shared_ptr<const uint8_t> with a custom deleter to
represent MediaSample::data_ instead of std::vector<uint8_t>.

MediaSample::data_ can be shared by multiple MediaSamples and it is
immutable. A new data instance must be created if the clients want to
modify the underlying data. The new data instance can be transferred
to MediaSample using provided MediaSample::TransferData function.
This avoids unnecessary data copying.

KongQun Yang 9c861d03f7 Report an error when disk is full
Previously packaging completes successfully without any error
or warning.

With the fix, an error will be reported if write fails. It may
appear as "Cannot close file error" as we use threaded IO, which
could delay the error reporting until Close() call, so the user
of the File API needs to make sure Close() returns successfully.

Also fixed a deadlock in threaded_io_file if internal_file->Write
fails.

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.

- 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.
