How to setting TVP5158 2-Ch Line-Interleaved Mode

I am also curious on the settings for 2-CH, I am using the TVP5158 with the DM6467T and I have no idea on how they got the values for the 2-CH D1 mode on the MCVIP driver.

Hi,

Please refer http://software-dl.ti.com/dsps/dsps_public_sw/dsps_swops_houston/ANALOG_VIDEO/DM_TVP5158_Driver.htm driver.

Hi Hyun,

I have looked at that but I get this error that I can't figure out:

I put alot of printk's in my vpif_capture.c. As you can see when it calls the ioctl(fd, VIDIOC_S_FMT, &fmt)  located in mcfip_v4l2.c it fails. That is why I ask where are you getting these values from for the NTSC_STD's (2-CH, 4-CH D1, ect....)?

Eager for help!
