LoadMode :number
In order to know what method of loading the player used for some content, we
have this enum. It lets us know if content has not been loaded, loaded with
media source, or loaded with src equals.
This enum has a low resolution, because it is only meant to express the
outer limits of the various states that the player is in. For example, when
someone calls a public method on player, it should not matter if they have
initialized drm engine, it should only matter if they finished loading
content.

TYPICAL_BUFFERING_THRESHOLD_ :number
The typical buffering threshold. When we have less than this buffered (in
seconds), we enter a buffering state. This specific value is based on manual

To make the buffering logic work in all cases, this "typical" threshold will
be overridden if the rebufferingGoal configuration is too low.

closeLcevcDec_()
Close a shaka.lcevc.Dec object if present and hide the canvas.
- Source:
Changes configuration settings on the Player. This checks the names of
keys and the types of values to avoid coding errors. If there are errors,
this logs them to the console and returns false. Correct fields are still
applied even if there are other errors. You can pass an explicit
undefined
value to restore the default value. This has two
modes of operation:
First, this can be passed a single "plain" object. This object should
follow the shaka.extern.PlayerConfiguration object. Not all fields
need to be set; unset fields retain their old values.
Second, this can be passed two arguments. The first is the name of the key
to set. This should be a '.' separated path to the key. For example,
'streaming.alwaysStreamText'
. The second argument is the
value to set.

onManifestUpdate_()
Callback from StreamingEngine.
- Source:
When notified of a media quality change we need to emit a
MediaQualityChange event to the app.
Parameters:
- Source:
onRateChange_()
A callback for when the playback rate changes. We need to watch the
playback rate so that if the playback rate on the media element changes
(that was not caused by our play rate controller) we can notify the
controller so that it can stay in-sync with the change.
- Source:
onRegionEvent_(eventNamenon-null, region, eventTargetopt)
When we fire region events, we need to copy the information out of the
region to break the connection with the player's internal data. We do the
copy here because this is the transition point between the player and the
app.
Parameters:
- Source:
onSeek_()
Callback from Playhead.
- Source:
onSegmentAppended_()
Callback from StreamingEngine.
- Source:
onTextChanged_()

pollBufferState_()

says so that we can update the rest of the buffering behaviours.
- Source:
preload(assetUri, startTimeopt, nullable, mimeTypeopt, nullable) → {Promise.<?shaka.media.PreloadManager>}
Starts to preload a given asset, and returns a PreloadManager object that
represents that preloading process.
The PreloadManager will load the manifest for that asset, as well as the
initialization segment. It will not preload anything more than that;
this feature is intended for reducing start-time latency, not for fully
downloading assets before playing them (for that, use
|shaka.offline.Storage|).
You can pass that PreloadManager object in to the |load| method on this
Player instance to finish loading that particular asset, or you can call
the |destroy| method on the manager if the preload is no longer necessary.
If this returns null rather than a PreloadManager, that indicates that the
asset must be played with src=, which cannot be preloaded.

Select a specific text track.
track
should come from a call to
getTextTracks
. If the track is not found, this will be a
no-op. If the player has not loaded content, this will be a no-op.
Note that AdaptationEvents
are not fired for manual track
selections.
Parameters:

label uniquely identifies an audio stream, so all the variants
are expected to have the same variant.audio.

selectVariantTrack(track, clearBufferopt, safeMarginopt)
Select a specific variant track to play.
track
should come
from a call to

. If
track
cannot
be found, this will be a no-op. If the player has not loaded content, this
will be a no-op.
Changing variants will take effect once the currently buffered content has
been played. To force the change to happen sooner, use
clearBuffer
with safeMargin
. Setting
clearBuffer
to true
will clear all buffered
content after safeMargin
, allowing the new variant to start
playing sooner.
Note that AdaptationEvents
are not fired for manual track
selections.

without causing a buffering event. Defaults to 0 if not provided. Ignored
if clearBuffer is false. Can cause hiccups on some browsers if chosen too
small, e.g. The amount of two segments is a fair minimum to consider as
safeMargin value. |
