/****************************************************************************
* 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 ;-)
