// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

* @property {string} [movingAverageMethod="slidingWindow"]
* Sets the moving average method used for smoothing throughput estimates. Valid methods are
* "slidingWindow" and "ewma". The call has no effect if an invalid method is passed.
*
* The sliding window moving average method computes the average throughput using the last four segments downloaded.
* If the stream is live (as opposed to VOD), then only the last three segments are used.
* If wide variations in throughput are detected, the number of segments can be dynamically increased to avoid oscillations.
*
* The exponentially weighted moving average (EWMA) method computes the average using exponential smoothing.
* Two separate estimates are maintained, a fast one with a three-second half life and a slow one with an eight-second half life.
* The throughput estimate at any time is the minimum of the fast and slow estimates.
* This allows a fast reaction to a bandwidth drop and prevents oscillations on bandwidth spikes.
* @property {string} [ABRStrategy="abrDynamic"] Returns the current ABR strategy being used: "abrDynamic", "abrBola" or "abrThroughput".
* @property {number} [bandwidthSafetyFactor=0.9]
* Standard ABR throughput rules multiply the throughput by this value. It should be between 0 and 1,
* with lower values giving less rebuffering (but also lower quality).
* @property {boolean} [useDefaultABRRules=true] Should the default ABR rules be used, or the custom ones added.
* @property {boolean} [useBufferOccupancyABR=false] Whether to use the BOLA abr rule.
* @property {boolean} [useDeadTimeLatency=true]
* If true, only the download portion will be considered part of the download bitrate
* and latency will be regarded as static. If false, the reciprocal of the whole
* transfer time will be used.
* @property {boolean} [limitBitrateByPortal=false] If true, the size of the video portal will limit the max chosen video resolution.
* @property {boolean} [usePixelRatioInLimitBitrateByPortal=false]
* Sets whether to take into account the device's pixel ratio when defining the portal dimensions.
* Useful on, for example, retina displays.
* @property {module:Settings~AudioVideoSettings} [maxBitrate={audio: -1, video: -1}] The maximum bitrate that the ABR algorithms will choose. Use NaN for no limit.
* @property {module:Settings~AudioVideoSettings} [minBitrate={audio: -1, video: -1}] The minimum bitrate that the ABR algorithms will choose. Use NaN for no limit.
* @property {module:Settings~AudioVideoSettings} [maxRepresentationRatio={audio: 1, video: 1}]
* When switching multi-bitrate content (auto or manual mode) this property specifies the maximum representation allowed,
* as a proportion of the size of the representation set.
*
* You can set or remove this cap at anytime before or during playback. To clear this setting you set the value to 1.
*
* If both this and maxAllowedBitrate are defined, maxAllowedBitrate is evaluated first, then maxAllowedRepresentation,
* i.e. the lowest value from executing these rules is used.
*
* This feature is typically used to reserve higher representations for playback only when connected over a fast connection.
* @property {module:Settings~AudioVideoSettings} [initialBitrate={audio: -1, video: -1}] Explicitly set the starting bitrate for audio or video
* @property {module:Settings~AudioVideoSettings} [initialRepresentationRatio={audio: -1, video: -1}] Explicitly set the initial representation ratio. If initalBitrate is specified, this is ignored.
* @property {module:Settings~AudioVideoSettings} [autoSwitchBitrate={audio: true, video: true}] Indicates whether the player should enable ABR algorithms to switch the bitrate.

* @property {number} [abandonLoadTimeout=10000]
* A timeout value in seconds, which during the ABRController will block switch-up events.
* This will only take effect after an abandoned fragment event occurs.
* @property {number} [liveDelayFragmentCount=4]
* Changing this value will lower or increase live stream latency. The detected segment duration will be multiplied by this value
* to define a time in seconds to delay a live stream from the live edge. Lowering this value will lower latency but may decrease
* the player's ability to build a stable buffer.
* @property {number} [liveDelay]
* <p>Equivalent in seconds of setLiveDelayFragmentCount</p>
* <p>Lowering this value will lower latency but may decrease the player's ability to build a stable buffer.</p>
* <p>This value should be less than the manifest duration by a couple of segment durations to avoid playback issues</p>
* <p>If set, this parameter will take precedence over setLiveDelayFragmentCount and manifest info</p>
* @property {boolean} [scheduleWhilePaused=true]
* Set to true if you would like dash.js to keep downloading fragments in the background
* when the video element is paused.
* @property {boolean} [fastSwitchEnabled=false]
* When enabled, after an ABR up-switch in quality, instead of requesting and appending the next fragment
* at the end of the current buffer range it is requested and appended closer to the current time
* When enabled, The maximum time to render a higher quality is current time + (1.5 * fragment duration).
*
* Note, When ABR down-switch is detected, we appended the lower quality at the end of the buffer range to preserve the
* higher quality media for as long as possible.
*
* If enabled, it should be noted there are a few cases when the client will not replace inside buffer range but rather
* just append at the end. 1. When the buffer level is less than one fragment duration 2. The client
* is in an Abandonment State due to recent fragment abandonment event.
*
* Known issues:
* 1. In IE11 with auto switching off, if a user switches to a quality they can not download in time the
* fragment may be appended in the same range as the playhead or even in the past, in IE11 it may cause a stutter
* or stall in playback.
* @property {number} [bufferPruningInterval=10] The interval of pruning buffer in sconds.
* @property {number} [bufferToKeep=20]
* This value influences the buffer pruning logic.
* Allows you to modify the buffer that is kept in source buffer in seconds.
* 0|-----------bufferToPrune-----------|-----bufferToKeep-----|currentTime|
* @property {number} [bufferAheadToKeep=80]
* This value influences the buffer pruning logic.
* Allows you to modify the buffer ahead of current time position that is kept in source buffer in seconds.
* <pre>0|--------|currentTime|-----bufferAheadToKeep----|----bufferToPrune-----------|end|</pre>
* @property {boolean} [jumpGaps=true] Sets whether player should jump small gaps (discontinuities) in the buffer.
* @property {number} [smallGapLimit=1.8] Time in seconds for a gap to be considered small.
* @property {number} [stableBufferTime=12]
* The time that the internal buffer target will be set to post startup/seeks (NOT top quality).
*
* When the time is set higher than the default you will have to wait longer
* to see automatic bitrate switches but will have a larger buffer which
* will increase stability.
* @property {number} [bufferTimeAtTopQuality=30]
* The time that the internal buffer target will be set to once playing the top quality.
* If there are multiple bitrates in your adaptation, and the media is playing at the highest
* bitrate, then we try to build a larger buffer at the top quality to increase stability
* and to maintain media quality.
* @property {number} [bufferTimeAtTopQualityLongForm=60] The time that the internal buffer target will be set to once playing the top quality for long form content.
* @property {number} [longFormContentDurationThreshold=600]
* The threshold which defines if the media is considered long form content.
* This will directly affect the buffer targets when playing back at the top quality.
* @property {number} [wallclockTimeUpdateInterval=50] How frequently the wallclockTimeUpdated internal event is triggered (in milliseconds).
* @property {boolean} [lowLatencyEnabled=false] Enable or disable low latency mode
* @property {boolean} [keepProtectionMediaKeys=false]
* Set the value for the ProtectionController and MediaKeys life cycle. If true, the
* ProtectionController and then created MediaKeys and MediaKeySessions will be preserved during
* the MediaPlayer lifetime.
* @property {boolean} [useManifestDateHeaderTimeSource=true]
* <p>Allows you to enable the use of the Date Header, if exposed with CORS, as a timing source for live edge detection. The
* use of the date header will happen only after the other timing source that take precedence fail or are omitted as described.
* @property {boolean} [useSuggestedPresentationDelay=false]
* <p>Set to true if you would like to override the default live delay and honor the SuggestedPresentationDelay attribute in by the manifest.</p>
* @property {number} [manifestUpdateRetryInterval=100]
* For live streams, set the interval-frequency in milliseconds at which
* dash.js will check if the current manifest is still processed before
* downloading the next manifest once the minimumUpdatePeriod time has
* @property {number} [liveCatchUpMinDrift=0.02]
* Use this method to set the minimum latency deviation allowed before activating catch-up mechanism. In low latency mode,
* when the difference between the measured latency and the target one,
* as an absolute number, is higher than the one sets with this method, then dash.js increases/decreases
* playback rate until target latency is reached.
*
* LowLatencyMinDrift should be provided in seconds, and it uses values between 0.0 and 0.5.
*
* Note: Catch-up mechanism is only applied when playing low latency live streams.
* @property {number} [liveCatchUpMaxDrift=0]
* Use this method to set the maximum latency deviation allowed before dash.js to do a seeking to live position. In low latency mode,
* when the difference between the measured latency and the target one,
* as an absolute number, is higher than the one sets with this method, then dash.js does a seek to live edge position minus
* the target live delay.
*
* LowLatencyMaxDriftBeforeSeeking should be provided in seconds. If 0, then seeking operations won't be used for
* fixing latency deviations.
*
* Note: Catch-up mechanism is only applied when playing low latency live streams.
* @property {number} [liveCatchUpPlaybackRate=0.5]
* Use this method to set the maximum catch up rate, as a percentage, for low latency live streams. In low latency mode,
* when measured latency is higher/lower than the target one,
* dash.js increases/decreases playback rate respectively up to (+/-) the percentage defined with this method until target is reached.
*
* Valid values for catch up rate are in range 0-0.5 (0-50%). Set it to 0 to turn off live catch up feature.
*
* Note: Catch-up mechanism is only applied when playing low latency live streams.
* @property {module:Settings~CachingInfoSettings} [lastBitrateCachingInfo={enabled: true, ttl: 360000}]
* Set to false if you would like to disable the last known bit rate from being stored during playback and used
* to set the initial bit rate for subsequent playback within the expiration window.
*
* The default expiration is one hour, defined in milliseconds. If expired, the default initial bit rate (closest to 1000 kbps) will be used
* for that session and a new bit rate will be stored during that session.
* @property {module:Settings~CachingInfoSettings} [lastMediaSettingsCachingInfo={enabled: true, ttl: 360000}]

* The placeholder buffer increases the effective buffer that is used to calculate the bitrate.

* 1. When a segment finishes downloading, we would expect to get a call on getMaxIndex() regarding the quality for
* the next segment. However, there might be a delay before the next call. E.g. when streaming live content, the
* next segment might not be available yet. If the call to getMaxIndex() does happens after a delay, we don't
* want the delay to change the BOLA decision - we only want to factor download time to decide on bitrate level.
*
* 2. It is possible to get a call to getMaxIndex() without having a segment download. The buffer target in dash.js
* is different for top-quality segments and lower-quality segments. If getMaxIndex() returns a lower-than-top
* quality, then the buffer controller might decide not to download a segment. When dash.js is ready for the next
* segment, getMaxIndex() will be called again. We don't want this extra delay to factor in the bitrate decision.

temporal (t) - This dimension denotes a specific time range in the original media, such as "starting at second 10, continuing until second 20";
spatial (xywh) - this dimension denotes a specific range of pixels in the original media, such as "a rectangle with size (100,100) with its top-left at coordinate (10,10)";
Media fragments support also addressing the media along two additional dimensions (in the advanced version defined in Media Fragments 1.0 URI (advanced)):
track (track) - this dimension denotes one or more tracks in the original media, such as "the english audio and the video track";
id (id) - this dimension denotes a named temporal fragment within the original media, such as "chapter 2", and can be seen as a convenient way of specifying a temporal fragment.
## Note
Akamai is purposing to add #s=X to the ISO standard.
- (X) Value would be a start time to seek to at startup instead of starting at 0 or live edge
- Allows for seeking back before the start time unlike a temporal clipping.
