Just recompiled with the latest and greatest. The following is the command
and output. It appears to have made no difference.
ffmpeg -loglevel 48 -c:v mpeg2video -f mpegts -i out.ts -f mp4 -c:v
h264_rkmpp -c:a libfdk_aac -preset ultrafast -mbd rd -copyinkf -flags

Hello, I really need the ability to use http_proxy from CLI. The

Hello!
I'm transcoding/resizing some UDP live streams using CUVID and NVENC. It
works but I got the feeling could be better, this is the my command line:
ffmpeg -vsync 0 -hwaccel cuvid -c:v h264_cuvid -resize 1280x720
-drop_second_field 1 -i udp://
