这个是balckfin533/561的MPEG和Mjpeg的源代码

This would result in the encoding of a VGA resolution sequence at quality 
factor of 60 to a file my_sequence.avi.

Typically, Q factors of 80~90 or less are used. Since there is little 
quality gain at Q-factors above 90, it is debatable whether these gains 
justify the significant increase in file sizes and in MIPS.

6. Operational Description
---------------------------

- Open the "JPEG-MJPEG_BF561.dpj" project in the VisualDSP 
  Integrated Development Environment (IDDE). 
      
- Build the project by selecting "rebuild all" from the project menu. 
  The project gets automatically loaded in to DSP

- Connect USB port from PC to the USB port of the Blackfin USB-LAN Ez-Extender 
  with the given USB cable

- Connect a video display monitor (Television) to the video output jack 
  (white coloured RCA-style jack)

- Connect a ITU656 NTSC/PAL interlaced video source (DVD player) to video input jack 
  (red coloured RCA-style jack)

- Run the executables by pressing "multiprocessor run" (CTRL-F5) on the toolbar.

  If this is the first time the program is run, Windows will claim to have 
  detected new hardware, and prompt for a driver.  The driver is located in 
  "BlackfinSDK\Tools\Windows Drivers\USB-LAN EZ-EXTENDER BULK USB" directory.  
  Once installed, Windows will not ask for the driver again the next time 
  the application is run.

- Once the program starts running, the user should give the EZ-Kit and the 
  PC a few seconds to initialize and install the USB driver, before using 
  the host application (Bin\pc2bf.exe)
