Hello,
I observe a strange behavior of the MPEG4 encoder on my DM368 based camera.
I grab images with 1600x1200. When I encode AOIs with a height <= 976 AND a width > 1280 i get artifacts on all pixels on the right side with x > 1280. The aoi position has no effect on the problem. The problem occur with CBR and Fixed QP.
Here is an example using a test image . The errors fade into the left side of the image during a GOP. The I-frames are ok and the errors are reset at the end of the GOP.
My encoder version: 01.10.00.01
