// 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.

     * 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.

    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.

    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.
