Linux/AM5718: GStreamer qp-max-i property

j-breeze

Part Number: AM5718

Tool/software: Linux

Hi Champs,

I am evaluating a GStreamer pipeline below.

ducatih264enc bitrate=1024 entropy-coding-mode=1 qp-max-i=40 qp-min-i=26 profile=main level=level-51

I changed the value of qp-max-i to 40 from 30, but it seemed to be invalid.
So, could you please let me know how to enable the property?

Regards,

Hello,

Could you try to set rate control params preset as user user defined.
I would also recommend you to check the h264enc user guide about the encoder's params.

I checked the URL and I've got a message below.

I'm not sure how to view the raw data.
