This is a fix for issue #216 where the Representation::SlideWindow() logic was
still active even though a static MPD was being asked to be generated (using
the option -generate_static_mpd). This could cause static streams longer than
1800 seconds to start playing at (end-position-for-stream - 1800 seconds).
This change is in compliance with the current usage documentation for the
shaka-packager, which suggests that -time_shift_buffer_depth only is relevant
for dynamic media presentations.
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
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.

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.

- Simple implementation of MPEG2 TS muxer.
- This does not take MuxerListener so a manifest cannot be generated.
- Encryption is not supported.

- Segmenter should not finish a segment unless the next sample is a key
frame.
- Renamed PesPacketGenerator::Finalize() to Flush().
- Use duration from the sample instead of the one copied to PesPacket.
- Remove duration field from PesPacket.

- Multi-file segmenter implementation.
- The samples are passed to PesPacketGenerator to generate PesPackets.
PesPackets are passed to TsWriter to write them to file.

The positions in the SeekHead element should be relative to the
Segment payload, not the start of the file. Also added entries for
Tracks and SegmentInfo.

This script can be used to parse and generate PSSH boxes. This
serves two purposes:
* Parse PSSH boxes into a human readable format.
* Take several arguments to generate PSSH boxes.
This is also able to parse Widevine and PlayReady PSSH data and will
print the parsed data instead of the data as binary. This can also
generate Widevine PSSH data instead of having the PSSH data passed
as an argument.

- Optimize and clean up encryption and decryption code.
- Consolidate various CBC encryption/decryption schemes into a
common class.
- Make it a constructor argument whether cipher block chain is
continuous across Encrypt/Decrypt calls.
- Also align protected region size as required in CENC spec.

Another feature that the mac build does not support. It incorrectly
uses a copy-constructor when creating new values in a std::map. This
is incorrect and should use an in-place constructor with C++11.

This adds a preliminary H.265 parser. The parser only support
reading the slice header. This also attaches the H.265 parser to the
VideoSliceHeaderReader so H.265 frames can have unencrypted headers.

The flag --include_common_pssh will add another PSSH box in addition
to the Widevine one which will contain the key IDs of all the keys.

- Use 'builddir_name' environment variable to create the output
path in test_env.py
- This allows running the packager test with different build
configs because it doesn't use 'out', e.g. it could use 'out_clang'
for clang builds.

The new algorithm will parse NAL unit header and only starts a new
NAL unit if it is valid, otherwise it will be considered part of
the previous NAL unit.

KeySource is now an abstract class that is implemented in two
types WidevineKeySource and FixedKeySource. This also updates
fixed key encryption to use v1 PSSH boxes with the common system
ID.
This also updates the --pssh argument. Now it accepts full PSSH
boxes rather than data. Multiple PSSH boxes can be concatenated
together.
Issue #88
Change-Id: I4bd0290f6d8b965f7d118f075c96e0f267d7e831
- Part 1.
- Add packager command line argument "protection_scheme" to specify
protection scheme. Plumb through packager code to enable CBC
encryption/decryption.
- Add scheme type "cbc1" to sinf.
- Refactor AES encryptor and decryptor.
- Need more work in the subsample handling.

* EncryptionKey now contains them rather than a PSSH box.
* Outputs PSSH boxes for each entry.
* Outputs a ContentProtection element for each entry.
* Removed SystemName and UUID from KeySource.
* Removed --scheme_id_uri packager argument.

This adds a new function to key AdaptationSets based on the
characteristics that require separate sets.
With this, we are now able to package multi-codec assets at once
(AVC1/MP4 and VP9/WebM in the same manifest, but in different
AdaptationSets).

When normalizing language tags to their shortest form, we need to
split off subtags and treat them as separate components that do not
get changed.
Furthermore, MP4 can only store language tags without subtags. So
only store the main language in MP4 output.

Add another overload to fetch by key ID directly, used by WebM.
Changed the one using PSSH data in favor of the entire PSSH box.
This also moves the Widevine proto to media base. Now, the
Widevine key source handles creating the Widevine specific PSSH
data.
Change-Id: I6f4633facad39207809ffbad970635d1f9d70983
This moves pssh parsing to its own class in media base. This type
can be used to parse and generate pssh boxes. This new type also
supports both v0 an v1 boxes.
This also modifies the pssh box definition to only have the |raw_box|
and moves all pssh parsing and handling into mp4 media parser.
A follow-up change will replace the remaining usages of 'raw' pssh
box data with the new type.

This moves common parsing code out of the H.264 parser. This is in
preparation for the H.265 parser to use.
Change-Id: Id05b55f6adc2ea31e97c8a9f22023e851808a8a7
Now the AVCDecoderConfiguration and HEVCDecoderConfiguration classes
will read the Nalu from the blocks, meaning they will store a
vector of Nalu objects for the data.
Also added H.265 to the Nalu class and added argument to NaluReader
to read H.264 vs H.265 Nalus.

This is needed to test encryption in end to end test since the video
is segmented in gop boundary by default. Due to the existence of clear
lead, the first segment is always left in clear.
