Windows 10 amd64 can not open Camera

[fjfo]

Your environment.

• Version: golang 1.16
• OS: Windows 10, amd64

What did you do?

    x264Params, err := x264.NewParams()
must(err)
x264Params.Preset = x264.PresetMedium
x264Params.BitRate = 1_000_000 // 1mbps

codecSelector := mediadevices.NewCodecSelector(
	mediadevices.WithVideoEncoders(&x264Params),
)

mediaStream, err := mediadevices.GetUserMedia(mediadevices.MediaStreamConstraints{
	Video: func(c *mediadevices.MediaTrackConstraints) {
		c.FrameFormat = prop.FrameFormat(frame.FormatI420)
		c.Width = prop.Int(640)
		c.Height = prop.Int(480)
	},
	Codec: codecSelector,
})
must(err)

videoTrack := mediaStream.GetVideoTracks()[0].(*mediadevices.VideoTrack)
defer videoTrack.Close()
videoReader := videoTrack.NewReader(false)
var buf bytes.Buffer

	imgFrame, release, err := videoReader.Read()
	if err == io.EOF {
		return
	}
	must(err)

	out, _ := os.Create("./img.jpeg")
	defer out.Close()

	err = jpeg.Encode(out, imgFrame, nil)
	if err != nil {
		log.Println(err)
	}
	release()
	buf.Reset()

What did you expect?

• Open Camera and write 1 Frame to disk

What happened?

• Error: errConnectFilters = "failed to connect filters";

It seems

"github.com/pion/mediadevices/pkg/driver/camera" // This is required to register camera adapter

Can not work in Windows 10????????

Any helps please!

same issues,are there any gcc dependencies missing?

I copy the snippet example ,and run, then find same issue.The program have find one camera,but could't run. stream, err := mediadevices.GetUserMedia(mediadevices.MediaStreamConstraints{ Video: func(constraint *mediadevices.MediaTrackConstraints) { // Query for ideal resolutions constraint.Width = prop.Int(600) constraint.Height = prop.Int(400) }, }) fmt.Println("stream error", err) the terminal message is: stream error failed to open device: failed to connect filters

Same problem, any process?

You may need to install CCCP, https://answers.informer.com/24666/receive-combination-intermediate-filters-found-connection.

It works for me.
