Seeing some failures on some platforms when compiled with clang
disabled:
GYP_DEFINES="clang=0" gclient runhooks
Several changes to make it work:
1. Mark packager code with packager_code=1 in GYP definitions.
2. Disable a few checks in non-packager code, which we do not have
direct control: dangling-else, deprecated-declarations,
unused-function
3. Fix the relevant errors in packager code.
4. Revert HAVE_STROPTS_H in curl config which is not available in
all linux distributions.

This patch also fixes a bug which was introduced in

while connecting with other handlers and at the same time it was assumed
SISO in the AdCueGenerator class. Now we assume SISO everywhere.

The keys can be specified in --keys option, with the form of
label=<label>:key_id=<32-digit hex string>:key=<32-digit hex string>,label=...
There can be multiple "label=..." block. The DRM label can be one
of "AUDIO, SD, HD, UHD1, UHD2" or a custom label.
Mark --key and --key_id as deprecated. We can achieve the same result
with --keys=label=:key_id=<key_id>:key=<key>.
Also add a new optional field in stream descriptor: drm_label, which
is used to overwrite the internally generated DRM label for the stream.
If not provided, the DRM label is generated automatically based on
audio/video information, e.g. resolution.

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.

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

Also fixed a deadlock in threaded_io_file if internal_file->Write

- This fixes the issue when one NAL unit has multiple
subsamples, which is allowed in spec and could happen
when the clear_bytes exceeds 2^16 bytes.
- The new algorithm updates the subsample entries in
following steps:
1) When NaluReader parses a new NAL unit, the
function splits subsamples and align them with the
NAL unit. It also finds the range of subsamples
for that NAL unit.
2) Drop or update subsamples of that NAL unit,
based on the type. Other inserted bytes are treated
as a new all-clear subsample.
3) Merge those subsamples if possible.

Shared libpackager can be built by setting libpackager_type to
shared_library, e.g.
GYP_DEFINES='libpackager_type=shared_library' gclient runhooks
ninja -C out/Debug
will generate libpackager.so in out/Debug/lib directory.
Here is a few other changes to make shared_library builds and
tests pass:
- Add several test parameters to packager.h, which is needed for
testing.
- Create a protoc.gypi from build/protoc.gypi but depending on
protobuf_full_do_not_use instead of protobuf_lite, since we need
protobuf_full_do_not_use for text parsing and generation of media
info proto. Somehow shared_library build does not allow mixed use
of protobuf_full_do_not_use and protobuf_lite.
- Remove the use of LazyInstance in version/version.cc and use static
variable directly. This is because LazyInstance needs AtExitManager
which may not be easy to setup when calling GetVersion.
- Allow skipping testPackageWvmInputWithoutStrippingParameterSetNalus
with flag --shared_library, which is needed as shared_library build
does not support --strip_parameter_set_nalus flag yet.

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.

The issue could lead to the MPD attribute mediaPresentationDuration being
wrongly generated for WebM streams with a duration longer than INT32_MAX.
The root-cause was that StreamInfo::set_duration() accepted an int instead of a
uint64_t. This seems like a pure typo, since StreamInfo already uses a uint64_t
internally for representing duration.
This CL also removes EncryptionConfig stream data type and merges it
into StreamInfo/SegmentInfo instead.

The spec actually requires all NAL units to be escaped, so there

This handler is a multi-in multi-out handler. If more than one input is
provided, there should be one and only one video stream; also, all inputs
should come from the same thread and are synchronized.
There can be multiple chunking handler running in different threads or even
different processes, we use the "consistent chunking algorithm" to make sure
the chunks in different streams are aligned without explicit communcating
with each other - which is not efficient and often difficult.
Consistent Chunking Algorithm:
1. Find the consistent chunkable boundary
Let the timestamps for video frames be (t1, t2, t3, ...). Then a
consistent chunkable boundary is simply the first chunkable boundary after
(tk / N) != (tk-1 / N), where '/' denotes integer division, and N is the
intended chunk duration.
2. Chunk only at the consistent chunkable boundary
This algorithm will make sure the chunks from different video streams are
aligned if they have aligned GoPs. However, this algorithm will only work
for video streams. To be able to chunk non video streams at similar
positions as video streams, ChunkingHandler is designed to accept one video
input and multiple non video inputs, the non video inputs are chunked when
the video input is chunked. If the inputs are synchronized - which is true
if the inputs come from the same demuxer, the video and non video chunks
are aligned.

The original code accumulates sample durations in seconds (double)
and then generates new segment / cluster by comparing the accumulated
value with configured value.
There may be loss of precision when accumulating values in double.
For example, with a GOP of 96 frames and frame rate of 24 fps; the
accumulated frame duration for 96 frames is 3.999999999999, which is
very close to 4.0 but not 4.0. Problem would arise if segment
duration is set to 4. The created segments would have a duration of
8 seconds instead of 4 seconds.
The new code accumulates sample durations in uint64_t relative to
input time scale; the configured segment duration will be converted to
timescale for comparison. This avoids loss of precision.

In H264, there may be multiple consecutive video slice NAL units
in the same frame. The original code assigns a new access unit
for every video slice NAL unit, which is incorrect.
Fixes#134.

Mimic iso-bmff behavior: either all the samples in a segment are encrypted
or all the samples are clear.

The right way to detect the presence of a keyframe in a BlockGroup
is to look for the absence of the ReferenceBlock element [1].

Also updated packager_test not to fill in output_format by default,
which will help catch these kinds of bugs.

This flag is needed to workaround the Chromium bug
https://crbug.com/398130, which uses decoding timestamp
in buffered range.

Packager should not care about this flag, whether it is supported
is up to the decoder.
Closes#126

- Add MuxerListener::OnEncryptionStart() for notifying that further
segments are encrypted.

- Cannot include PMT for following encrypted segments in the clear lead.
Some players consider them as conflicting codecs.
- Add EXT-X-DISCONTINUITY in front of first EXT-X-KEY to notify that the
codec is switching from e.g. "avc1" to "zavc".

Before, we converted the WebM configuration to MP4 in the video
client, however this lead to a bug when fields were missing. So
now don't convert until the cluster parser so the extra info from
the stream can be added.
This also fixes a bug where the value was not printed in the warning
logs.

Since the |extra_data| field contains codec-specific configuration
data, it makes sense to call it |codec_config|.

Although superframe index is not encrypted, it should still be inserted
into subsamples list (with cipher_bytes as 0).

- Add flags and stream descriptor fields for HLS.
- Remove fields from MuxerOptions. Instead pass them directly to
HlsNotifyMuxerListener.
- Rebase segment names to the master playlist's path where it makes
sense.

- 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.

This is part of the effort to support Opus in iso-bmff #83.
Changes in this CL:
- Add support for multiple SampleGroupDescription and SampleToGroup
boxes in TrackFragment box;
- Add support for SampleGroupDescription and SampleToGroup boxes
in SampleTable box;
- Add support for AudioRollRecoveryEntry in Sample Group and 'roll'
sample grouping type;
- Also fix a bug that default length was not set correctly in
SampleGroupDescription when constant iv is used.

- For encrypted segments, PMT specified by SAMPLE-AES specification is
generated.
- Remove time_scale_ field from TsWriter. It is not used.
- Move ContinuityCounter to a separate file.
- Add ProgramMapTableWriter and implementations.
- continuity_counter is incremented for PAT and PMT.

This add several unit tests for EsParserH26x to test the various
NAL unit orders and access unit contents. Some tests are disabled
and will be fixed in another patch.
