DRA829V: Can LDC module of VPAC support rotation?

Part Number: DRA829V
Other Parts Discussed in Thread: DRA829

Hi, expert:

As customer's mechanical design, the camera module mount position is not as expected. The input video stream is about 130 degree angle. So it is needed to rotate the input camera video stream to 130 degree.

the camera module output format is YUV422.

My question is: Can LDC of VPAC support this kind of rotation (130 degree)?

(whether can it support 130 degree rotation of YUV420 data)

Thanks.

Yes, LDC can support rotation of both YUV422 and YUV420 images.

Hi, Gang:

one more question, please:

Is there any code example for reference to achieve below flow? (according to my understanding, it is doable, but please double check)

(Especially the reference code of doing rotation in LDC?)

Single Camera Sensor (YUV422, 1080p)-> UB933 -> UB964 -> DRA829 CSI -> DDR -> LDC (for 130 degree rotation) -> DDR (probably the LDC output resolution of this image will be smaller than 1080p)

Many thanks.

Hi Peter,

Please refer to this post: https://e2e.ti.com/support/processors/f/791/p/879017/3254350?tisearch=e2e-quicksearch&keymatch=LDC%20conformance%20test#3254350

Ming in your team has done very similar things with LDC recently.

Best,

Gang
