+- sync issues after seeking on osx
+  - prefill on start is aggressive, fills all buffers... on playback start
+    we (usually) have enough, but that's not true after seeking (why's it
+    different?)
+- prefill timing behaviour is different on osx vs linux:
+  linux takes ~6ms before prefill callback - actually seening it called
+  immediately while stream_init waits on STREAM_READY
+  osx prefills immediately from stream_init
+  so it's likely that osx underruns when linux may not
+- prefill needs some amount of data, depending on latency (and maybe platform)
+  - decoder needs to know how much before so it can decode ahead
+  - or it can write silence and deal with it via underrun handling
+    - except that means we have [audio ...] [inserted gap] [audio ...]
+      which is stupid, so the caller needs to know how much is required for
+      prefill
+  - *also* need xrun handling for real xruns, where we've run out of data
+     and must write silence and adjust the clock by it
+- deal with interaction between prefill and short files
+  - allow callback to signal how much has been written as well as EOS
+- document thread safety
+- document what is and isn't safe inside callbacks, locking, blocking, cubeb calls
+- clarify samples vs frames vs bytes, introduce types or something
+- add silence insertion code
+- underrun handling for decoder
+- fix locking in callbacks
+- implement basic support for windows
+- get tests passing on windows
+- get pulse volume sane
+- test (and fix) small file handling
+- implement correct channel mapping

+  - vorbis has documented mapping based on channel count (if mapping type == 0)

+
+NOTES:
+- osx drain: fill buffer in prefill, return EOS.  listener set up for drain.
+  then user starts playback.
+  listener fires for playing==true.
+- AudioQueueGetCurrentTime can return negative mSampleTimes - why?
+
+============================================================================
+
+  start with basic stuff:
+  - callback to get data
+  - preflight buffering (user needs to know how much to prepare first?)
+  - per-stream volume
+  - threading model
+  - underrun handling model
+  - vorbis channel mappings
+
+
+  preflight - read a bunch of data before starting playback.
+   - user needs to know how much to prepare.
+
+  channel mapping - per vorbis spec
+   - what if particular mapping not available?
+     http://www.xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-800004.3.9
+   - pick next one down and remix?
+
+  per-stream volume
+   - if we can't provide, cubeb will implement in software
+
+  implement formats in software by resampling
+
+  callback states:
+   preflight
+   playing
+   destroy
+
+  user can handle destroy as immediate or play-all-before-destroy by
+  reacting in callback.  actually doesn't work if latency is high so much
+  audio is buffered--need a way to force immediately destroy.  maybe destroy
+  while playing = drain, destroy while stopped = immediate?  one of stop or
+  destroy must provide an immediate option.
+
+  all of the library calls should return immediately.  this means any
+  potentially blocking operation (drain) must be notified via a callback.
+  should we reuse the audio callback for this, or use a new callback?
+  possibly use new, but structure it so the user can reuse the same callback
+  for both.
+
+  -> data callback, requests (or supplies -- for input) data
+  -> state callback, indicates a state change when it happens
+
+  must make guarantees about when callbacks will and won't run.  e.g. if
+  stream destroyed, no more callbacks run.  if a callback is currently
+  running... what? block the destroy or return but let the callback
+  complete?
+
+  callback timestamp is latest playback pos.  user can store this for
+  playback pos.  but then depends on callback latency -- not good idea to
+  callback as fast as we can provide position updates if it's unnecessary?
+
+  underrun handling?
+
+basic api:
+
+ctx = init(rate, channels, format, latency, data_callback)
+start(ctx)
+... data_callback runs on some thread ...
+ms = get_time(ctx)
+set_volume(ctx, v)
+stop(ctx, mode) : mode = now/drain
+... guarantee no data_callbacks after stop returns ...
+start(ctx)
+... data_callback runs on some thread ...
+ms = get_time(ctx)
+set_volume(ctx, v)
+stop(ctx, mode) : mode = now/drain
+destroy(ctx) (if running, calls stop)
+
+mode now = pause and keep buffered data to play when started
+mode drain = pause after remaining buffers played
+mode flush = pause and drop buffered data
+
+
+introduce types for samples and frames
+
+
+============================================================================
+from bugzilla:
+============================================================================
+The plan is to build a small library that maps closely to modern sound APIs
+(PulseAudio on Linux, CoreAudio (AudioQueue) on OS X, and either DirectSound or
+XAudio2 on Windows).  Rather than exposing a push-to-play model like
+sydneyaudio (which effectively requires a separate thread per playing media
+element to write audio), a callback will be called when more audio is required.
+
+It may be necessary to provide an ALSA backend in addition to the PulseAudio
+one, depending on the minimum Linux distro requirements post Firefox 4.
+
+Requirements:
+- remove necessity for 1-2 threads per active audio stream that we currently
+have (bug 592833)
+- underrun behavior/handling should be the same on each platform
+- low latency volume changes (bug 487504)
+- sharing top-level audio resources (bug 617852)
+- correct playback of sub-one-buffer length audio chunks (bug 615452)
+
+Reviewing some important aspects of existing behaviour:
+
+Playback start:
+- Linux: when start threshold reached
+- OS X: after first write
+- Win32: when block filled
+
+With a callback based model, this problem mostly disappears.  The library can
+decide what an appropriate initial buffer size is and explicitly request that
+the application fill it.
+
+Underrun:
+- Linux: audio clock stops ticking
+- OS X: audio clock continues at normal rate (callback writes silence)
+- Win32: audio clock stops ticking
+
+It's preferable for the clock to stop ticking.  The only reason it doesn't on
+OS X is that I'm not aware of a way to stop it--the implementation is already
+using a callback model, and when a callback requests more data than is
+available, it's not obvious what you can do other than write silence.
+
+API calls while underrun:
+- Linux: return error, usually return useless (initial state) values after
+recovery
+- OS X: work as there's effectively no underrun state
+- Win32: return frozen state at point of underrun
+
+Ideally the underrun recovery should be dealt with in a single place, so other
+API calls should try to return sensible values when playback is stopped due to
+underrun.
+
+Underrun recovery:
+- Linux: explicit, expensive, partial buffers lost
+- OS X: N/A
+- Win32: implicit (write more), cheap, no buffers lost
+
+There's not much control available of this, it's an attribute of the OS's audio
+API.
+
+Clock granularity:
+- Linux: unknown (but probably discoverable), often not more than one period
+length
+- OS X: dependent on callback buffer request size
+- Win32: unknown, seems fairly high (likely sample accurate)
+
+Clock read cost:
+- Linux: medium to high, cross-DSO call, possibly involving IPC
+- OS X: low, reads a local counter protected by a lock
+- Win32: medium, cross-DSO call
+
+In the current implementation, the caller may call the clock read function in a
+tight loop (with very short sleeps in between).  In the older Firefox media
+playback engine, it was assumed that the clock was fine enough granularity that
+individual video frames could be timed based on the audio clock updates. 
+Either the clock granularity must be explicit, high, and fast to read, or the
+API must be designed in such a way that the application can't easily make
+inappropriate assumptions about the clock's behaviour.

+dnl @synopsis AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
+dnl
+dnl the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
+dnl existence of an include file <stdint.h> that defines a set of
+dnl typedefs, especially uint8_t,int32_t,uintptr_t. Many older
+dnl installations will not provide this file, but some will have the
+dnl very same definitions in <inttypes.h>. In other enviroments we can
+dnl use the inet-types in <sys/types.h> which would define the typedefs
+dnl int8_t and u_int8_t respectivly.
+dnl
+dnl This macros will create a local "_stdint.h" or the headerfile given
+dnl as an argument. In many cases that file will just "#include
+dnl <stdint.h>" or "#include <inttypes.h>", while in other environments
+dnl it will provide the set of basic 'stdint's definitions/typedefs:
+dnl
+dnl   int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
+dnl   int_least32_t.. int_fast32_t.. intmax_t
+dnl
+dnl which may or may not rely on the definitions of other files, or
+dnl using the AC_CHECK_SIZEOF macro to determine the actual sizeof each
+dnl type.
+dnl
+dnl if your header files require the stdint-types you will want to
+dnl create an installable file mylib-int.h that all your other
+dnl installable header may include. So if you have a library package
+dnl named "mylib", just use
+dnl
+dnl      AX_CREATE_STDINT_H(mylib-int.h)
+dnl
+dnl in configure.ac and go to install that very header file in
+dnl Makefile.am along with the other headers (mylib.h) - and the
+dnl mylib-specific headers can simply use "#include <mylib-int.h>" to
+dnl obtain the stdint-types.
+dnl
+dnl Remember, if the system already had a valid <stdint.h>, the
+dnl generated file will include it directly. No need for fuzzy
+dnl HAVE_STDINT_H things... (oops, GCC 4.2.x has deliberatly disabled
+dnl its stdint.h for non-c99 compilation and the c99-mode is not the
+dnl default. Therefore this macro will not use the compiler's stdint.h
+dnl - please complain to the GCC developers).
