- Split sample pools for video/audio/misc, since the typical
required sample sizes are very different (and so it becomes
inefficient to use a sample sized for video to hold audio).
- Add TODO for further improvements.
Issue: #174
- Move all three buffering constants to a single class (the
chunk source).
- Increase the target buffer to 40s for increased robustness
against temporary network blips.
- Make values configurable via the chunk source constructor.
- Treat captions as a text track for HLS. This allows them to
be enabled/disabled through the demo app UI.
Issue: #165
- Add options to switch abruptly at segment boundaries. Third
parties who guarantee keyframes at the start of segments will
want this, because it makes switching more efficient and hence
rebuffering less likely.
- Switch quality faster when performing a splicing switch (when
we detect that we need to switch variant, we now immediately
request the same segment as we did last time for the new variant,
rather than requesting one more segment for the old variant
before doing this.
1. Correctly replace the AES data source if IV changes.
2. Check the largest timestamp for being equal to MIN_VALUE, and
handle this case properly.
3. Clean up AES data source a little.
Issue: #162
The actual fix here is to not call discardExtractors in HlsSampleSource
whilst the loading thread that's pushing data into it is still running.
It's required to wait for that thread to have exited before doing this.
Issue: #159
Passing uncropped dimensions to certain decoders will make them
output frames without proper cropping set.

- The HlsSampleSource now owns the extractor. TsChunk is more or less dumb.
The previous model was weird, because you'd end up "reading" samples from
TsChunk objects that were actually parsed from the previous chunk (due to
the way the extractor was shared and maintained internal queues).
- Split out consuming and reading in the extractor.
- Make it so we consume 5s ahead. This is a window we allow for uneven
interleaving, whilst preventing huge read-ahead (e.g. in the case of sparse
ID3 samples).
- Avoid flushing the extractor for a discontinuity until it has been fully
drained of previously parsed samples. This avoids skipping media shortly
before discontinuities.
- Also made start-up faster by avoiding double-loading the first segment.
