Hi, everyone.
I have a problem about DM36x convert YUV data format.
In resizer, dm36x can convert data format from yuv422 to yuv420sp.
In venc, dm36x can convert data format from yuv420sp to yuv422 or rgb565.
I want to know the sample and interpolation algorithms. Is it just simply copy the data from the 4:2:0 samples twice to create the 4:2:2 data? This tends to make the chroma channel look blocky, and accentuates the jaggedness. When I display the video use yc16 digital output pin and display .avi file recorded by Appro_avi_save, the chroma error happened. If I use the yuv422 format as the display source, the chroma error of vertical disappeared.
Any help and suggest would be appreciate!
Thanks!
