InputOptions help

[BrennaEpp]

Hi, I'm not sure whether this is not working or if I am doing it wrong. I want to pass in options so I can trim the video.

Here is the code:

	buf := &bytes.Buffer{}
	err := fluentffmpeg.NewCommand("./ffmpeg-binaries/ffmpeg").
		InputOptions("-ss 00:00:10").
		InputPath("./video.mp4").
		OutputFormat("mp4").
		OutputPath("./trim.mp4").
		Overwrite(true).
		OutputLogs(buf).
		Run()

	if err != nil {
		log.Fatal(err)
	}

This returns exit status 1.

The above does not return an error if InputOptions is empty, but even InputOptions("") returns an error. Is this working as intended?

Hi @BrennaEpp, you need to separate the input options into multiple strings or ffmpeg will interpret "-ss 00:00:10" literally as one argument.

// FFmpeg returns: Unrecognized option 'ss 00:00:10'
fluentffmpeg.NewCommand("").InputOptions("-ss 00:00:10").OutputPath("./trim.mp4")

// Works
fluentffmpeg.NewCommand("").InputOptions("-ss", "00:00:10").OutputPath("./trim.mp4")

In the future you can also read from the buffer you supplied to OutputLogs to get a more descriptive error straight from ffmpeg 👍
