Hi,
How to encode video with the maximal bitrate that NVidia supports?
Regards.
Hi igal, do you mean lossless encoding with all frames in qp = 0? H264 or HEVC? What is the resolution?
DaneLLL, hi,
I’d like to encode H.264 at 720p resolution with a bitrate of 32Mbps. How should I accomplish it with GStreamer?
Please refer to https://developer.nvidia.com/embedded/dlc/l4t-accelerated-gstreamer-guide-28-2-ga
