Could anyone share his source codes for imx53 vpu decoder that can decode more than one instance simultaneously?

Hi Everyone:

      I'm working on  imx53 smd board using WinCE7 OS. From Release Notes, it says that imx53 can decode 4 instances at same time.

      But the demo codes attached in WinCE bsp can only encode and decode one instance. So, can anyone share his demo source codes for imx53 that can decode two or more instances simultaneously ?

      Thanks .

Unfortunately we can not send you the VPU firmware code and its samples. However VPU encoder and decoder test cases have been demonstrated and implemented currently on the BSP, including multi-instatnce demo(dual video decoder +  display,  the first display LVDS panel, the second display is embedded HDMI display.)

In decoder test, there are two modes to select:

  1. Endless test
  2. Play the file to the end.

In the encoder test, the default encode stardard video, and default input size is 320*240. The output is stored in the memory. After the encoding finished, the user can select to play the encoded file at once, or else you can check the data in PC side by dumping them to files using debug tools.

also, Please check the following:

Hi Alfred:

       Thank you for your help , your answer is really important and helpful to me .

       I  have written an app which can decode four vedio files  and display the decoded pictures  on screen simultaneously .

      In order not to be fired by my boss , I dare not share source codes here ,  anyone who wants  to use vpu to do this kind of job  can  refer to your answer  and  demo app.

      Alfred, thanks  again for your help.
