- Admit we don't know the mime type (using unknown mime types) rather
than passing the container mime type.
- Pass the correct mime type for opus, vp9 and vp8, and remove the incorrect
container checks in the corresponding extensions.
- Fix building with APP_ABI=all by configuring for all architectures.
- Keep vpx_dsp which is required for building successfully.
- Use perl -pi -e not sed, for building on Macs.
- With this change, you can select from the individual video formats in
the demo app, as well as the regular "auto" (adaptive) track.
- DashRendererBuilder no longer needs to create MultiTrackChunkSource
instances for the multiple tracks to be exposed.
I think such manifests are invalid, and I haven't seen any examples,
but given it's trivial to fill in the duration if the periods define
durations, it seems worth being robust.
- It's not possible to determine a period's duration just from the
corresponding Period element in a DASH manifest. It's necessary
to look at the start time of the next period (or the duration of the
manifest for the last period) to determine how long a period is. We
don't currently do this in the parser, and hence set duration incorrectly.
We also set period start times incorrectly because we don't set it to
equal to sum of the durations of prior periods in the case where it's
not explicitly defined.
- We're currently propagating these (incorrect) values all over the place
through data-structures that we build when parsing the Period element.
- This CL removes this redundancy, storing only the start time of each
period in Period elements, and not propagating it elsewhere. It's then
used when required in DashChunkSource.
The following sequence was problematic:
1. See start of a cluster having not output a seek map. Decide
to seek for the cues. Enter CUES_STATE_BUILDING state.
2. Error occurs before seek map is output.
3. ExtractorSampleSource isn't prepared yet, so restarts from the
start of the stream.
4. See start of the same cluster having not output a seek map.
This time cuesState is CUES_STATE_BUILDING, so we just carry
on. We then fill the buffer with sample data, despite the
source not being prepared, at which point we get stuck.
It's unclear to me why cuesState needed three states, so I've rm'd
the BUILDING state. Step (4) above will now do the same thing as
in step (1). If the failure repeats, we'll eventually fail, which
is WAI.
These MP3s are unseekable but allow calculating the VBR duration correctly.
Treat streams as live only if they are unseekable and lack a duration.
Issue: #713
- Remove unused method in DashChunkSource.
- Remove inputEncoding parameter for subtitle parsers. We're
ignoring it in all but one of the parsers, and for the one
that does use it, it'll only ever receive null, since that's
all we're passing.
- Make TextTrackRenderer advance to the next subtitle even if
the current one hasn't finished, in the case that they overlap.
This shouldn't ever really happen, but it seems best to trust
the start time of the new sample rather than the last event
time of the previous one.
- Video track is always marked as adaptive, the resolution is
stripped out (since it's otherwise just set to whatever the
resolution of the first selected variant is), and the max
dimensions are set.
Issue #514
This is needed for several use cases:
- ExtractorSampleSource with option to play both embedded and out-of-band
subtitles.
- HLS multi-audio and out-of-band-webvtt.
