  25  * NOTES:
  26  *
  27  * mpegplayer is structured as follows:
  28  *
  29  *                       +-->Video Thread-->Video Output-->LCD
  30  *                       |
  31  * UI-->Stream Manager-->+-->Audio Thread-->PCM buffer--Audio Device
  32  *         |       |     |                        |     (ref. clock)
  33  *         |       |     +-->Buffer Thread        |
  34  *    Stream Data  |             |          (clock intf./
  35  *     Requests    |         File Cache      drift adj.)
  36  *                 |          Disk I/O
  37  *         Stream services
  38  *          (timing, etc.)
  39  *
  40  * Thread list:
  41  *  1) The main thread - Handles user input, settings, basic playback control
  42  *     and USB connect.
  43  *
  44  *  2) Stream Manager thread - Handles playback state, events from streams
  45  *     such as when a stream is finished, stream commands, PCM state. The
  46  *     layer in which this thread run also handles arbitration of data
  47  *     requests between the streams and the disk buffer. The actual specific
  48  *     transport layer code may get moved out to support multiple container
  49  *     formats.
  50  *
  51  *  3) Buffer thread - Buffers data in the background, generates notifications
  52  *     to streams when their data has been buffered, and watches streams'
  53  *     progress to keep data available during playback. Handles synchronous
  54  *     random access requests when the file cache is missed.
  55  *
  56  *  4) Video thread (running on the COP for PortalPlayer targets) - Decodes
  57  *     the video stream and renders video frames to the LCD. Handles
  58  *     miscellaneous video tasks like frame and thumbnail printing.
  59  *
  60  *  5) Audio thread (running on the main CPU to maintain consistency with the
  61  *     audio FIQ hander on PP) - Decodes audio frames and places them into
  62  *     the PCM buffer for rendering by the audio device.
  63  *
  64  * Streams are neither aware of one another nor care about one another. All
  65  * streams shall have their own thread (unless it is _really_ efficient to
  66  * have a single thread handle a couple minor streams). All coordination of
  67  * the streams is done through the stream manager. The clocking is controlled
  68  * by and exposed by the stream manager to other streams and implemented at
  69  * the PCM level.
  70  *
  71  * Notes about MPEG files:
  72  *
  73  * MPEG System Clock is 27MHz - i.e. 27000000 ticks/second.
  74  *
  75  * FPS is represented in terms of a frame period - this is always an
  76  * integer number of 27MHz ticks.
  77  *
  78  * e.g. 29.97fps (30000/1001) NTSC video has an exact frame period of
  79  * 900900 27MHz ticks.
  80  *
  81  * In libmpeg2, info->sequence->frame_period contains the frame_period.
  82  *
  83  * Working with Rockbox's 100Hz tick, the common frame rates would need
  84  * to be as follows (1):
  85  *
  86  * FPS     | 27Mhz   | 100Hz          | 44.1KHz   | 48KHz
  87  * --------|-----------------------------------------------------------
  88  * 10*     | 2700000 | 10             | 4410      | 4800
  89  * 12*     | 2250000 |  8.3333        | 3675      | 4000
  90  * 15*     | 1800000 |  6.6667        | 2940      | 3200
  91  * 23.9760 | 1126125 |  4.170833333   | 1839.3375 | 2002
  92  * 24      | 1125000 |  4.166667      | 1837.5    | 2000
  93  * 25      | 1080000 |  4             | 1764      | 1920
  94  * 29.9700 |  900900 |  3.336667      | 1471,47   | 1601.6
  95  * 30      |  900000 |  3.333333      | 1470      | 1600
  96  *
  97  * *Unofficial framerates
  98  *
  99  * (1) But we don't really care since the audio clock is used anyway and has
 100  *     very fine resolution ;-)
