You could use context to set the timeout: ctx, cancel := context.WithTimeout(context.Background(), time.Second * 5) You will need FFmpeg installed on your machine, or you can specify a path to a binary: // Provide an empty string to use default FFmpeg pathĬmd = fluentffmpeg.NewCommand("/path/to/ffmpeg/binary")Ĭreate and run commands using an API similar to node-fluent-ffmpeg: err := fluentffmpeg.NewCommand(""). Go get -u /modfy/fluent-ffmpeg Requirements
