Transcoding with a GeForce GTX 1070


#1

Hi,
I’ve a server with a GeForce GTX 1070 and I’m trying to use hardware for transcoding my videos (only for adding watermark).
I used ffmpeg on this server and it works with the GPU using the following command line:
ffmpeg ajout logo : /opt/flussonic/bin/ffmpeg -c:v h264_cuvid -i infile.mp4 -i logo.png -filter_complex … -c:v h264_nvenc -codec:a copy out.mp4

The input file is h.264 720x576.

My flussonic.conf is:
file archived {
path /opt/videos/archived;
auth /etc/flussonic/watermark.lua;
cache /opt/videos/flussonic/cache 10G;
}

Plugins:

plugin dynafile {
cache /opt/videos/flussonic/dynacache 2G;
transcoder vb=2048k hw=nvenc size=720x576 ab=64k;
}

The result is:

  • CPU (8 cores) is at 50-75%
  • GPU is not used at all
  • reading with the embedded player regularly freezes

In the logs (syslog and flussonic.log) I can see that it does not use GPU, only CPU. In fact I can see no evidence of using GPU.
