- 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.
- 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.
- 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.
When ChunkSource implementations implement multi-track for DASH and SS,
format selection will move inside of ChunkSource. If we, for example, fail
to query the decoder to determine which tracks are playable, we need an
opportunity to fail (i.e. say we're not prepared, so that maybeThrowError
is called, from which we can throw).
This may go away in the future if we remove the distinct preparation step
and treat tracks/formats as things that can change dynamically, but for now
this is what we have.
Issue #514.
multi-track support upstream to the ChunkSource interface.
This change does not yet make use of the newly exposed APIs. This
will come in a subsequent CL.
Issue #514.
- Parse all attributes that may exist in either the AdaptationSet or
in the child Representation elements at both levels.
- Correctly infer TYPE_TEXT for Representation elements whose mimeType
is application/mp4 and whose codecs attribute indicates a known text
codec type.
Issue: #689
- contentType can be defined on an AdaptationSet.
- language can be defined either in AdaptationSet or in a contained
ContentComponent.
- The id from the AdaptationSet should come from the AdaptationSet.
ChunkSampleSource had a null check solely for the VTT case,
where DashChunkSource wasn't setting a MediaFormat on VTT
chunks. It's trivial to do so, and is more consistent, so I've
done that and removed the null check. Also done some small
tidying.
They're current location is annoying, because it creates a dependency
from the dash package to the webvtt package. For apps like Play Movies
where WEBVTT isn't used, it's nice just to delete the whole package at
import time, which requires that this dependency be removed.
For Live SmoothStreaming, referential equality checking
isn't enough (it breaks once the manifest is updated).
Updated other instances too just for consistency.
Using a file:// URL for loading an HLS stream (for testing) would fail due to
casting the connection to an HttpURLConnection in DefaultHttpDataSource.
This change makes UriDataSource an interface for objects that are DataSources
with URIs. That allows for reading manifests for HLS using just a UriDataSource
rather than an HttpDataSource (URLs in the playlist are relative to the data
source's URL so the getUri method is needed).
