Question

尝试解码＆amp;在我的GPU上对FFMPEG中的视频进行编码。使用此命令：

ffmpeg -y -c:v mpeg2_cuvid -vsync 0 -deint 2 -drop_second_field 1 -surfaces 10 -i 'udp://@227.10.20.149:1234?fifo_size=100000000'  -map i:0x12c -r 25 -filter fps=30,scale_npp=640:360:format=same:interp_algo=lanczos -aspect 16:9 -g 96 -vcodec h264_nvenc -b 400K -minrate 400k -maxrate 400k -f mpegts 'udp://@239.0.0.12:1000?overrun_nonfatal_option=1'

但是FFMPEG仍然给我这个输出：

  Using -vsync 0 and -r can produce invalid output files
  Stream mapping:
  Stream #0:8 -> #0:0 (mpeg2video (mpeg2_cuvid) -> h264 (h264_nvenc))
  Stream #0:8 -> #1:0 (mpeg2video (mpeg2_cuvid) -> h264 (h264_nvenc))
  Stream #0:8 -> #2:0 (mpeg2video (mpeg2_cuvid) -> h264 (h264_nvenc))
  Stream #0:8 -> #3:0 (mpeg2video (mpeg2_cuvid) -> h264 (h264_nvenc))
  Stream #0:9 -> #4:0 (mp2 (native) -> aac (native))
  Stream #0:10 -> #5:0 (mp2 (native) -> aac (native))

Use -h to get full help or, even better, run 'man ffmpeg'

我尝试将输出编解码器更改为hevc_nvenc，nvenc_hevc（均可从Nvidia获得），但仍然出现此错误。我做错了什么？谢谢你的提示。
