  2.11.  Global Structure of Payload Format

     The RTP payload following the RTP header, contains three octet-

     Figure 1.

Note that auxilary section is empty for AAC-hbr

  3.2.1.  The AU Header Section

   When present, the AU Header Section consists of the AU-headers-length
   field, followed by a number of AU-headers, see Figure 2.

 * with the appropriate box/descriptor.
 *
 * To add a new box, follow the same pattern: you need an object with at least
 * the property 'box' (which is 'Box' or 'FullBox') and for non-container boxes
 * you need also a 'body' property specifying the elements that the box contains.
 * The values assigned to each element in the spec are used as default.

/*
 * The RTSP response format is defined in RFC 7826,
 * using ABNF notation specified in RFC 5234.
 * Strings in ABNF rules ("...") are always case insensitive!
 *
 * Basic rules to help with the headers below:
 * ====
 * CR              =  %x0D ; US-ASCII CR, carriage return (13)
 * LF              =  %x0A  ; US-ASCII LF, linefeed (10)
 * SP              =  %x20  ; US-ASCII SP, space (32)
 * HT              =  %x09  ; US-ASCII HT, horizontal-tab (9)
 * CRLF            =  CR LF
 * LWS             =  [CRLF] 1*( SP / HT ) ; Line-breaking whitespace
 * SWS             =  [LWS] ; Separating whitespace
 * HCOLON          =  *( SP / HT ) ":" SWS
 *
 * RTSP response rules (a `*` means zero or more):
 * ====
 * Status-Line  = RTSP-Version SP Status-Code SP Reason-Phrase CRLF
 * Response     = Status-Line
 *                *((general-header
 *                /  response-header
 *                /  message-body-header) CRLF)
 *                CRLF
 *                [ message-body-data ]
 *
 * Example response:
 * ====
 * RTSP/1.0 200 OK
 * CSeq: 3
 * Content-Type: application/sdp
 * Content-Base: rtsp://192.168.0.3/media/media.amp/
 * Server: GStreamer RTSP server

// 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.

// 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.
