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