Video Capture driver for DM6446

Hello,

I am currently working on Video capture driver for TMS320DM6446 in QNX.
Can anyone provide me a video capture reference driver?

Thanks,
Sakshar

I’m not sure what you mean by a “reference driver” but you might want to ask Mario as he had done a video capture driver for an ethernet based video device.

Yes but it had no ties what so ever with Photon.

Thanks for the quick reply…
By reference driver I meant source code of a video driver in QNX which I can refer to understand its framework and architecture.

The framework will be that of a resource manager. Every piece of hardware will have different hardware interface requirements, and potentially different efficiency requirements. For example, if you are using a camera that moves a lot of data, it might be required that the resource manager manage a shared memory area for the client and the driver code so that data is only transfered once.
