Other Parts Discussed in Thread: TVP5146
Hi All
I am trying to capture a movie from TVP5146 analog video decoder from TVP5146 module on AM5728-evm, and I use 'ti-processor-sdk-linux-am57xx-evm-06.03.00.106' SDK. I followed 'AM5728 VIP and V4L2 interface with TVP5146 Analog Video Decoder Problem' thread, and now I can see these messages on 'dmesg' output.

When I run a Yavta command 'yavta -c60 -fUYVY -Fvout_720x576_yuyv.yuv -s720x576 /dev/video1', the system fails to set format:
Device /dev/video1 opened. Device `vip' on `platform:vip2:vin3a:stream0' is a video output (without mplanes) device. Unable to set format: Invalid argument (22).
The 'dmesg' output after the execution of yavta command is as below:

I debuged the code, and I found that when the 'tvp514x_get_pad_format' is called, the 'filed', 'code', 'colorspace', 'width', and 'height' of the returned format is zero. Also 'tvp514x_set_pad_format' always returns 'EINVAL'. Can anyone help me to debug these two functions and find out why the system can't set the format?
I added some debug messages in the 'tvp514x_get_pad_format' and 'tvp514x_set_pad_format' of tvp514x.c file as follow:
