Other Parts Discussed in Thread: TVP7002
Hi All
Recently, I'm concerned about with how can i capture the multiplexed video stream (line multiplexed 1080p60fps, 16bit) with VIP0, VIP1.
Firstly, I considered the V4L2 capture.
But, It looks like support only VIP0 according to TI81XX_Video_Capture_Driver_User_Guide document.
It meas that i can not use VIP1 port to capture 1080p30fps (line multiplexed video stream, 16bit)
Actually, I'd like to capture the 1080p30fps 2 stream with VIP0 and VIP1 respectively.

Features
V4L2 capture driver supports following features.
• Supports VIP0 instance of the VPSS.
• Supports TVP7002 standard Linux sub device driver.
• Supports YUV422 interleaved, YUV422 semiplanar, YUV420 semiplanar and RGB888 color formats to memory.
• Supports scaling and cropping for YUV formats (downscaling only)
• Supports 1080P60, 1080P30, 1080I60 and 720P60 input resolutions.
• Supports user pointer buffer mechanism of the V4L2 driver interface.

Therefore, I'm considering using OMXIL VFCC component to capture it.
Unfortunately, I also find out these sentence from OMX_05_02_00_48_UserGuide.pdf document as below.
I think ... it means that VFCC can not capture the line multiplexed 1080p60fps (16bit) video stream.
Please, Are there anyone who advise me about capturing line multiplexed 1080p60fps (1080p30fps + 1080p30fps) 16bit with OMXIL VFCC ?
Is it possible with VFCC ?
