I'm not sure exactly what the implications of this change are,
but I'd really hope that only one program in each stream is carrying
audio/video. For GoPro cameras, they expose the video stream in
the second program, for some reason.
Issue: #116
We've seen a few streams where this assertion fails. If you
just skip the packet, things appear to recover correctly in
all cases I've seen, so replacing failure with a warning.
- Handle read returning NOTHING_READ for AC-3 streams.
- Remove extra checks for the audio track being initialized.
- Call isInitialized() instead of checking audioTrack != null.
ac3Bitrate is set only after the first buffer is handled, which meant that
getting the playback position would cause a divide by zero before then.
When playing back AC-3 content, the ac3Bitrate will always be set after the
first buffer is handled, so return a 0 position if it is not set.
- Adds support for dash manifests that define SegmentTemplate
but no SegmentTimeline.
- Assumes that the device clock is correct when calculating which
segments to load. The final step here is to use the Utc timing
element in the DASH manifest to obtain an accurate client clock.
- Doesn't yet enforce that the client shouldn't load segments that
are in the future or behind the live window.
This fixes the referenced issue, except that the MPD parser
needs to actually parse out UUID and binary data for schemes
that we wish to support. Alternatively, it's easy to applications
to do this themselves by extending the parser and overriding
the parseContentProtection and buildContentProtection methods.
Github Issue: #119
It's cleaner to not inject data into the extractor only
so that it can be read out as though it were parsed from
the stream. This is also an incremental step towards
fixing Github issue #119.
Note: This adds support for the majority of DASH live streams,
however we do not yet correctly support live streams that rely
on UtcTimingElements in their manifests.
Issue: #52
Plus start to properly document the SmoothStreaming package.
Note that where the documentation is a little vague, this is
because the original SmoothStreaming documentation is equally
vague!
- 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
The timestamp scaling in SegmentBase.getSegmentTimeUs was
overflowing for some streams. Apply a similar trick to that
applied in the SmoothStreaming case to fix it.
- 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.
