How to capture composite video on DM8148EVM?

Other Parts Discussed in Thread: TVP5147, TVP7002

I want to capture a composite video (480i) using TVP5147 video decoder
on DM8148 EVM. I am using EZSDK 5.03.
I could make "tvp5147.ko", but I don't know how to add TVP5147 driver.
Should I edit "$kernel_source/arch/arm/mach-omap2/ti81xx_fb.c"? (which
line/how should I edit?) Or, should I edit other sources?

And, I think, when I use sample application "capture_encode" with a
composite video (480i) using TVP5147 video decoder, I have to change
input setting in "capture_encode" sample.
How can I change the setting for a composite video (480i) input?

please let me know!

Hi,

Are you using V4L2 or EZSDK?

Dear　Shah

I use EZSDK sample (capture_encode).
This sample can chose only 1080p or 720p format.
I want to capture composite video (480i) on this sample.
How can I capture composite video (480i) on "capture_encode" sample?

Hi,

For capturing the 480i using TVP5147, you need to add driver for TVP5147 which can be configured using A8, You need not to use TVP7002 control component for setting up of TVP7002. You also have to do some changes in VFCC on how the TVP5147 is interfaced to VIP, as it will be 8-bit interfaced compared to 16-bit with TVP7002. I am not very sure of these changes. I will forward this to our OMX team here.
