Hi,
My application is running on i.MX6Q. I'm using the IPU ioctl() operations to display the video. The input and output video parameters like the resolutions, Hight, width, colour formate, ......., etc changes dynamically. Sometimes the input and output are exactly the same so a call to ioctl(fd_ipu, IPU_CHECK_TASK, &ipu_t); returns IPU_CHECK_ERR_PROC_NO_NEED which perfectly makes sense.
My questions is it possible in such situation to ask the IPU to display the video directly from the VPU decoder buffer without any conversion?
Ideally I would like the input and output buffer to be the same, but if that's not possible can I ask the IPU to DMA the video frame from VPU buffer to the display frame buffer /dev/fb1? How?
Thanks,
Tarek
