Hi.

For JPEG encoder have a question.

Output image of jpeg encoder is broken, when qvalue is between 91 and 97.

I am looking for a solution to this problem.

Sdk environment that I have used is as follows.

・board: TMX320DM365 Digital Video Evaluation Module BETA

・sdk: ti-dvsdk_dm365-evm_4_02_00_06.

・application: dmai_2_20_00_15 image_encode_io1

Apllication command line args is as follows.

./image_encode_io1_dm365.x470MV -i /opt/sbin/random.yuv -c jpegenc -r 640x240 --qValue 97 --iColorSpace 3 --oColorSpace 2 -o demo.jpg -e encode

Input image is random noise image that high-frequency component is large.

Thanks for your help.

Hi,

Its a known issue, with high quality factor + XDM_YUV_422ILE format.
With normal input scene we will see few artifacts, and might be more as complexity of input scene increases, when Quality factor is high.
