[FFmpeg-user] how to capture live stream nvenc help

[Daniel]

Hello everyone

i am trying to capture live stream with ffmpeg my video card is nvidia 
gtx 960 and here is the command i am using:

/usr/local/bin/ffmpeg  -i http://192.168.98.197:4242/bysid/1002 -s 
640x320 -acodec libfdk_aac   -c:v h264_nvenc  -r 25 -b:v 800k -preset 
llhq -f mpegts output1.mp4

unfortunately this command fails after 1min  with following error :
