Other Parts Discussed in Thread: TVP7002

Hi,

Can we use video input [1] capture port A to interface 8-bit BT.656 or BT.601 video input?

What firmware / software modification might be required to make the interface work?

Earliest reply is appreciated.

Hi,

Are you trying to use this with VFCC or V4l2 capture.

Hi,

You can use it. You need to update arch/arm/mach-omap2/ti81xx_fb.c file for your new decoder instead of supported TVP7002. Procedure for supporting new decoders is mentioned in app note at http://processors.wiki.ti.com/index.php/DM81xx_AM38xx_Adding_External_Decoders_to_V4L2_Capture_Driver
