AW_MPI_VI_SetVirChnAttr - tylerjbrooks - 09-16-2018
Does this call actually take an attribute structure? If so, which one?
My problem...
I want to setup two channels with different resolutions from the same sensor. One channel is 1080p and the other is 720p. I can create the VIPP for my sensor with the 1080p resolution and bind it to the encoder. Works fine. But there doesn't seem to be a way to ask the VI to scale down the image to 720p for the second channel. Is there a way to do this? Currently, I am doing a AW_MPI_VI_GetFrame on the second VI channel and then using G2D to scale down the image before I send it along to the encoder. That works but I am surprised I can't just ask the VI to do that.

In Lindenis V5 board，/dev/video0 and /dev/video2 link to MIPI_CSI 0, /dev/video1 and /dev/video3 link to MIPI_CSI 1.
So, video0 and video2 are showing the camera's picture. u can use video0 to 1080p, and usd video2 to 720p

Thank you Michael.
We just got our Lindenis V5 board. I will give that a try.
