Aaron Vaage 9a9f7d58b2 Update Cue Alignment Tests To Interweave Sample Data
Problem: Sending samples to the cue alignmenet handler did
         not reflect what was more likely to happen. In our
         tests we would send all the samples for one stream
         then all the samples for another stream. This created
         some special cases that would either not happen in
         reality or miss cases that would likely happen in
         reality.

Changes: Changes all tests to dispatch samples in an interlaced
         pattern that better reflects muxed content.

KongQun Yang 8767d20f38 Fix potential slice header size off by one byte in H265
In H265Parser::ParseSliceHeader, the parser does not handle
byte_alignment() from the spec. byte_alignment() reportedly contains
at least one bit, which is not handled right now.

See Section 7.3.2.12 Rec. ITU-T H.265 v3 (04/2015).

Also added a few size sanity checks in H265Parser to make sure the
code does not crash if an invalid input is provided.

Fixes #383.

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 a7463f60c1 Enable segment auto removal for live packaging
The number of preserved segments outside live window can be
configured using flag --preserved_segments_outside_live_window,
which is default to 50, i.e. 5 minutes for 6s segment.

Note that the segment removal will be disabled if it is set to 0.

Only HLS live playlist and DASH dynamic MPD are affected by this flag.

- Also add end to end tests.

KongQun Yang 224b597b48 Support approximate SegmentTimeline
It is not always possible to align segment duration to target duration
exactly. For example, for AAC with sampling rate of 44100, there are
always 1024 audio frames per sample, so the sample duration is
1024/44100. For a target duration of 2 seconds, the closest segment
duration would be 1.984 or 2.00533.

This feature allows MPD generator to treat these segments as having
the same duration, thus allows MPD generator to generate less
SegmentTimeline entries and potentially no SegmentTimeline entries
(replaced with SegmentTemplate@duration instead if
  --segment_template_constant_duration flag is enabled).

Under flag --allow_approximate_segment_timeline. Disabled by default.

Fixes #330.

KongQun Yang b2932d5a33 Fix bitrate for DASH on-demand profile too
Removed the logic in MuxerListener to estimate bandwidth from file
size and duration, since it is not compliant to the spec.

MpdBuilder will estimate bandwidth from segment size and duration
if bandwidth is not specified in MediaInfo.

Here is the statement from DASH spec (23009-1:2014):

Consider a hypothetical constant bitrate channel of
bandwidth with the value of this attribute in bits per second
(bps). Then, if the Representation is continuously delivered
at this bitrate, starting at any SAP that is indicated either by
@startwithsap or by any Segment Index box, a client can
be assured of having enough data for continuous playout
providing playout begins after @minbuffertime *
@bandwidth bits have been received (i.e. at time
@minbuffertime after the first bit is received).
For dependent Representations this value specifies the
bandwidth according to the above definition for the
aggregation of this Representation and all complementary
Representations.

KongQun Yang adc9549e2d Add new URL fields in MediaInfo
The file_name fields will be used to solely indicate file paths on the
designated file system, and they are used to do normal file operations,
including file creation, file updating and file removal if needed;
added new xxx_url fields, for the URLs that should appear on DASH
manifest or HLS playlists.

xxx_url are the URIs of the media in the manifest. The fields are
converted from file_name fields but adjusted to be relative to DASH
manifest path or HLS playlist path, optionally with base_url prepended.

Previously the file_name fields are converted in place to indicate
URLs when passing to manifest / playlist builders. The original file
names were lost, which made it difficult to remove files outside of
live window.

Now that the input file names are preserved. File system APIs can
operate on the original file names while manifest / playlist generation
functions can operate on URLs.

KongQun Yang 43be3c8e8b Use max bitrate in Representation@bandwidth instead of average bitrate
According to DASH spec (23009-1:2014):

Consider a hypothetical constant bitrate channel of
bandwidth with the value of this attribute in bits per second
(bps). Then, if the Representation is continuously delivered
at this bitrate, starting at any SAP that is indicated either by
@startwithsap or by any Segment Index box, a client can
be assured of having enough data for continuous playout
providing playout begins after @minbuffertime *
@bandwidth bits have been received (i.e. at time
@minbuffertime after the first bit is received).
For dependent Representations this value specifies the
bandwidth according to the above definition for the
aggregation of this Representation and all complementary
Representations.

This suggests that max bitrate should be used instead of average
bitrate.

Also cleaned up BandwidthEstimator code.

KongQun Yang 4549b1d569 Remove pto_adjustment flag
This flag was introduced to workaround a rounding error in Chrome
(probably in other browsers too).

Also although this flag avoids the first frame of a Period to be
dropped due to rounding error but it could cause the last frame of a
Period to be dropped.

Now that we use a high precision Period@duration, we do not expect to
see rounding errors any more. The player would be a better place for
the workaround even if it is still needed.

Instead, the actual earliest presentation time is used except for

(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).

Aaron Vaage b2ce6322b6 Remove Test File Index in packager_test.py
Instead of using the test file's index in a list to create the output
name, use the original filename and the descriptor.

This caused some problems with file name collisions when some tests
were using the same name. That was fixed by changing the names. This
will go away once they are transitioned to use DiffDir like the other
tests.

KongQun Yang ee9b7f6392 Calculate presentationTimeOffset and Period@duration from segments
Prefer timestamps from Video AdaptationSets if available - this avoids
possible video playback jitters due to gaps.

presentationTimeOffset is not applied to the first period as it may in
negative dts which Chrome does not like: https://crbug.com/398141.

It is safe to apply to subsequent periods as the actual offset applied
takes Period@start into consideration:

    offset = Period@start - presentationTimeOffset

The result timestamp with offset applied is close to Period@start, so
it is unlikely to result in a negative dts value.

Closes b/73899306.

This should not affect the repo size too much as duplicate files will
only be stored in the git object store once.

KongQun Yang 9ecee46658 Fix SAMPLE-AES EC3 encryption
The IV was incorrectly updated across samples.

Created a new cryptor SampleAesEc3Cryptor specially for SAMPLE-AES
EC3 encryption / decryption. The new cryptor uses constant-iv, and
makes sure the IV is reset to the initial value at the beginning
of each audio frame and chained across syncframes within the the
audio frame.

Also added E-AC3 end to end test.

KongQun Yang b74e511f29 Workaround for possible rounding errors in MSE
There could be rounding errors in MSE which could cut the first key
frame of the representation and thus cut all the frames until the next
key frame, which then leads to a big gap in presentation
timeline which stalls playback.

Adjusting presentationTimeOffset (PTO) by -1, i.e. backing off PTO by 1
to compensate for the possible rounding error. It should not cause any
playback issues as it is small enough. The workaround can be removed
once the problem is handled in all players.

The PTO adjustment is configurable with command line flag:
 --pto_adjustment, with value set to -1 by default.

KongQun Yang 32d26094ba [HLS] Support AUTOSELECT and DEFAULT in EXT-X-MEDIA
According to HLS spec: https://goo.gl/MiqjNd 4.3.4.1.1. Rendition Groups
- A Group MUST NOT have more than one member with a DEFAULT attribute of
  YES.
- Each EXT-X-MEDIA tag with an AUTOSELECT=YES attribute SHOULD have a
  combination of LANGUAGE[RFC5646], ASSOC-LANGUAGE, FORCED, and
  CHARACTERISTICS attributes that is distinct from those of other
  AUTOSELECT=YES members of its Group.

We tag the first rendition with a particular language in an audio group
with 'AUTOSELECT'; it is tagged with 'DEFAULT' too if the language
matches --default_language.

with GetEarliestTimestamp, the two new functions allows MpdBuilder to
iterate through the Representations to get durations.

Also updates GetEarliestTimestamp functions to use the same iteration
method.
