I configured the video registers in user space... But you must first Get access to the physical addresses using the mmap function On /dev/mem.
You can then use something like: *(volatile unsigned int *)(0x01C72400)=0x00002011; //VMOD *(volatile unsigned int *)(0x01C72404)=0x00002000; //VIDCTL *(volatile unsigned int *)(0x01C72408)=0x00000000; //VDPRO *(volatile unsigned int *)(0x01C7240C)=0x0000000F; //SYNCCTL ... Etc.
