Hi,
I have tried to use the 01_video_encode sample application on the Jetson Xavier NX with the --alliframes option. I set the QP-range between 1 and 2 but the encoder used different values. Also I tried different QP-values but the encoder keeps using it’s own choice of QP-values and no matter what QP-values I used in the execute-command the encoder always used the QP-values it chose for itself for every frame.
For example I used:
./video_encode ~/EncodeHSIImages/project/HSI_test_images/2022_44x64yuv420_10bituint16_msb_aligned.yuv 512 512 H265 /home/jetson/EncodingResults/Intra_only/2022_10bituint16nv_Intra_1_2.h265 -p main10 --insert-vui -MinQpI 1 -MaxQpI 2 -MinQpP 1 -MaxQpP 2 -MinQpB 1 -MaxQpB 2 -hpt 4 -bd 10 --alliframes
I expected the encoder to choose QP-values of 1 or 2. But I got the following:

Is there a way to prevent the encoder from automatically choosing the values for QP and force the encoder to use the ones I give in the execute-command?
Best regards.
