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 ?
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:
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.

Hope it helps
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.
