VPIF use with raw video

Clayton Reeves

I apologize for my lack of knowledge. I was brought on a project to help set up the development system and to see how far I could get on the setup of the DM6467 board. I currently have all of the needed things from the GSG put into place on the Linux machine to run the board off of its NFS directory. I can run the demos from both the interface and from the command line just fine.

The next step is to use a custom board that we developed in house that would run through what I think is called the VPIF.

If I am wrong on the exact input name it is the one that when a device is plugged into the port then it will override the MUX for component/composite. If I am off on this please let me know.

What we need to achieve is to bring raw video in from that port and encode it. When we get everything optimised we hope to be running 1080p at upwards of 20 fps.

Any help or pointers to were to find file to look at as reference would be great.

Again I apologize for my lack of knowledge in this area and appreciate any and all help that you could provide to me.

Thank you very much,

Clayton Reeves

Again, I apologize for my ignorance, but what on this page can help me understand how to set up a link to the serial port on the board?

Is there any documentation I could read through and see how to switch between the different modes of input, ie component, composite or the port?

Thank you all again in advance for your help.

These are some of the useful links that you might need to spend some time going through and understanding the SoC, setup and bootup procedures before actually getting into details of switching between video inputs:

and in general documentation found at :

I have gone through all of the documentation that has been suggested by people through this thread. I have also found other documents and source files to look through. Unfortunately none of these have told me how to access the VPIF and pull from it to verify that the board we developed works.

What I need is a program that will take the input from the VPIF and ether spit it back out through the component out or create a file that I can play on VLC player or some other media player.

Thank you all for your help and support,

Hello Clayton,

I have been watching your post becuase we are trying to do the same thing. Here is my current posting with a not so optimistic outcome. The summary is that TI does not have a raw VPIF driver and that we need to write one ourselves. Not sure this helps, but if we get anywhere - I will try to remember to post it on the website.
