ffmpeg nvenc 插logo问题。。。

zywu31

使用cuda硬解nvenc硬编   插入logo图片 总是出错 如果将-vf换成filter_complex一进多出失效
命令如下
     ./ffmpeg -hwaccel cuvid -c:v h264_cuvid  -i 'udp://238.121.100.12:1234?localaddr=192.168.10.156&pkt_size=1316&overrun_nonfatal=1' -i '/usr/local/res/1.png' -c:v hevc_nvenc -preset slow  -b:v 4000k -g 100  -vf 'hwdownload,format=nv12,overlay=100:100,hwupload_cuda,scale_npp=1920:1080'  -c:a aac -b:a 64k -f mpegts  'udp://236.1.1.1:1234?localaddr=192.168.11.121&pkt_size=1316'


错误信息如下
Simple filtergraph 'hwdownload,format=nv12,overlay=100:100,hwupload_cuda,scale_npp=1920:1080' was expected to have exactly 1 input and 1 output. However, it had >1 input(s) and 1 output(s). Please adjust, or use a complex filtergraph (-filter_complex) instead.
