Now I have finished transplanting the SDL_lib, and the examples that along with SDL_lib can run fine. And the spcaview I transplanted to ARM is run fine when I use cmd "spcaview -v -o test.avi", and the test.avi display fine in windows. Only when it display on ARM there is always breaking with "Segmentation error". The following is detail:
