Jetson encoder is producing very high bitrate IDR (at least double pframe, and even 10 times as high)
This happens when we limit the bitrate to 1.25Mbps or less.
We are using CBR settings.
We tried limiting the VBV value, and the QP.
How can we get actual CBR, while the IDR frames are consistent and relates to the requested size?
The frame resolution is 1920*1080.
Hi,
1.25Mbps is strict for 1920x1080p30 so it may not be able to achieve the target bitrate. The working solution is to run in CBR + setting virtual buffer size as you are doing now. The other property is to set
EnableTwopassCBR : Enable two pass CBR while encoding
