KongQun Yang 5dd21179ec Do not use harmonic mean in bandwidth calculation
Instead, caclulating average bandwidth by dividing the sum of the
sizes of every segment by the sum of the durations of every segment.
This aligns with the requirement in HLS spec:
https://tools.ietf.org/html/draft-pantos-http-live-streaming-23 4.1.

BandwidthEstimator is also simplified to handle all blocks only.

Aaron Vaage a510d3aa38 Print Error and Ignore Text Samples With Bad Times
Before we had an assert that would catch if a sample had an
invalid times, however input may have bad times.

We did have a message if we saw a sample with a duration equal to
zero. This expands that check to check if the time is valid in
general and will ignore any sample that is not valid.

KongQun Yang 1742e03471 Drepcate --num_subsegments_per_sidx
This flag was designed for two purpose:
- Grouping fragments into subsegments, achieving three level hierarchy:
  segment < subsegment < fragment.
- Indicate whether to generate 'sidx' box in media segments (when the
  value is set to a negative number).

There are no practical use case for the first purpose. Removing it to
simplify the code and reduce the confusion.

Introduce another flag --generate_sidx_in_media_segments for the second
purpose.

KongQun Yang 571ee24f3e Use PTS instead of DTS in ChunkingHandler
DTS was used in ChunkingHandler. As a result, SegmentInfo contained
timestamp in DTS. MP4Muxer has a logic to change SegmentInfo to use
PTS but not in other muxers.

Benefits of using PTS in ChunkingHandler:

- De-dup the redundant logic in MP4Muxer
- Ensure consistent behavior in different output containers
- Consistent with other timestamps, e.g. Ad Cue timestamps

Aaron Vaage 5f072e3b08 Start Segments At First Sample in Text Chunker
We always assumed that text stream started at zero in the text chunker.
This meant that if the text stream started later than zero (like in a
live stream) we would generate a lot of empty segments.

Instead the text chunker will assume that segments should be adjusted
to align with multiple of segment duration. The text chunker will assume
that an earlier component in the pipeline (i.e. text padder) will ensure
that the first sample has the time that we want to start segments at
(even it needs to add an empty sample).

Aaron Vaage 1600909c4b Don't Always Start Text At Time Zero
Previously, the text padder media handler would assume that text always
started at time zero. This would work for VOD but would result with a
large pad at the start of LIVE content.

To avoid this, the text padder will use a bias to test whether or not it
thinks the content starts at zero. Right now the bias is set to be 10
minutes, but will later be configurable with a command line flag.

10 minutes was used as LIVE content will have much larger values and VOD
content should have much lower values.

This is a more faithful implementation of more_rbsp_data().

There could be trailing null bytes in NAL units. This isn't valid per

PPS in the avcC record includes a trailing null byte.

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 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.
