Questions about QT cross-compile for A20 olinuxino

[hankgong]

Hello guys! Thanks for sharing your experience about QT cross compiling.

Recently I have cross compiled QT5.2.1 framebuffer for olimex A20 board with the help of posts in this forum. There is no error when I compiled it. But there are several things I want to ask here

- I tried to run the example "affine" and several other examples. The program will quit when I click "Opengl" button. Many other programs was running OK but the CPU usage is still as high as 100%. It seems that the opengl is not doing anything.

- I have seen someone declared that their QT can play video on A20. I'm wondering if the video playing will use hardware acceleration (I mean the cedar driver)? I tried to use the movieplay in widget example to play a mp4 file but it didn't do anything.
