Hello
I am working on DM6437. I am trying to do interlaced to planar conversion (422 to 420) using EDMA3 with chaining feature.
The EDMA3 separates the video components but a problem is encountered in displaying the video. It seems like the previous frame values are read from the buffer when the scene changes. A jerky effect appears in the video when the camera moves. I write back and invalidates the cache but the problem still persists.
But when chaining feature is not used and callback is used to trigger the transfer, the video appears smoothly but it utilizes more CPU percentage that's why I am trying to use chaining feature.
Kindly suggest some solution
Regards
SAIRA
