Aaron Vaage 5a9a49034b Merge Create and Dispatch in Cue Alignment Tests
Originally the create and dispatch of stream data in the cue
alignment tests were separate to improve readability. The idea was
to separate building each stream and dispatching the streams muxed
together would make it easier to understand the streams.

However, coming back to the code, this did not hold up as it took just as
long to understand the code. So merging the two together allows for the
code to be more concise.

Aaron Vaage b5cdfee73f Update "One to many" example in Media Handler
In the media handler there is an example of what a one-to-many media
handler would be. It used the trick play handler as an example, but that
handler is now a one-to-one media handler. Changed the example to use the
replicator media handler.

Aaron Vaage 8d800446f3 Align Trick Play Tests With Other Media Tests
We have adopted some new standards for how we are writing the media
unit tests. This change goes through the trick play tests and
updates them to be more inline with how we are doing new media
tests.

This include using "_" for parameters that are not the focus of the
tests (used in the EXPECT calls).

This includes wrapping Dispatch calls so that the test bodies can
be more readable.

Aaron Vaage fbc4952e21 Updated StreamData Matchers to Use Matchers
Updated all the stream data matcher we use in our unit tests
to allow us to use matchers in them. We are now able to use "_"
to ignore specific parameters.

With this we were able to replace the different version of
matchers for each stream data type with a single instance for
each type.

Includes updates to printing strings to the listener. Strings
now go through a "pretty" function to help make it easier to
read them in the output.

Aaron Vaage dbce84f3ea Remove Time Scale Assumptions From Text Chunker
Before, the text chunker would assume that all text streams were in
MS, which is not a safe assumption to make.

This changes it to take the time scale from StreamInfo and work
natively with scaled time units.

This required updating the tests. While doing so the tests were
rewritten with the goal to make them easier to read.

Aaron Vaage 47f20031dd WebVtt Text to MP4 - Test That No Payloads Becomes Gaps
Text Samples with no payload should be ignored, so this adds a
test to check that samples with no payload get treated the
same as a gap.

As long as this case is true, using gaps in our other tests should
functionally be the same as using samples with no payload.

Aaron Vaage b9dee56294 Rebuild Text WebVtt to MP4 WebVtt
The previous text to mp4 webvtt pipeline was incomplete. It
did not insert ad cues and it could only insert a segment
after a sample ended.

Now the pipeline supports ad cue insert and segment insertion
mid text sample. This required the pipeline to use the text
chunker (to split samples and insert segments) and required
a major overhaul of the text to mp4 converter.

Before the converter came before the chunker. This meant that
the converter only expected to see stream info and text samples.
Moving the converter after the cue aligner and chunker means
that the convert had to be aware of segments and cues.

The general approach is the same, however the converter will
convert the samples per-segment as the chunker will introduce
duplicate samples if a sample spans across segments.

         queue and insert them into each stream.

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.

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 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.

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.

Code changes:
- Merged RawKeyEncryptionParams and RawKeyDecryptionParams into
  RawKeyParams.
- Make FixedKeySource accepts RawKeyParams as input.

Aaron Vaage ec83d8a73a Implement MsToWebVTTTimestamp
Implemented the other end of the webvtt timestamp parsing as it will
be needed when we write out WebVtt files. Also changed the name of
the parse function to be more inline with the writing function.

origin) of a pipeline (chain of handlers).

Rintaro Kuroiwa 0dfdace280 Change MuxerListener::OnMediaEnd to take ranges
- Changed OnMediaEnd() to take (sub)segment ranges.
- Define a structure to pass the ranges.
- This requires muxers to "cache" the segment ranges but in most cases,
  they already do it, e.g. 'sidx' for mp4.

KongQun Yang 2db1867951 Write manifests atomically
In the original manifest updating process, the file was truncated first
before was written with new contents. There is a small chance that
the web server may read back empty file or incomplete file.

The new code makes the update operation atomic (by writing to a temporary
file first then replace the old file with the temporary file).
