Linux/DM3730: Interfacing TVP5146 with Logic PD Dm3730 SOM

Tool/software: Linux

Hello,

I just designed a custom board for interfacing TVP5146 with the LogicPD Dm3730 SOM. and my application is to capture the snapshot in the SD card.

Right now we had somehow managed to successfully compile & run the root file system from SD card. But when we give the command(mplayer tv:// -tv driver=v4l:device=/dev/video0:width=320:height=240:outfmt=rgb24 -frames 1 -vo jpeg) for saving the image, it shows me two different errors:

1- ioctl set format failed: Invalid argument

2- tvp514x 2-005d: Invalid control ID

So, can anyone guide me that how can I resolve this issue? Pl. see the attached log file snapshot.

I am very helpless.

Thanks in advance.
