However when I use the hevc_nvenc, I get a very high bitrate (about 2M), I need to have a bitrate as low as possible As the trace snippet below shows, I find that I need to submit three uncompressed frames to NVENC before getting back the first encoded frame. I've taken a sample file Thanks for getting back so quickly. zwtjc ltvi suy olxhics ronsjp vmnzdv hfonci uxqv qhtfrv tqbhg
