No stream from MacBook iSight

[MRvH88]

When using my iSight cam on my MacBook I cannot get a stream to homekit, in terminal I receive the following message: [avfoundation @ 0x7fd349000000] Selected framerate (30.000000) is not supported by the device

It shows the following frame rates are possible:
[avfoundation @ 0x7fd349000000] 1280x720@[29.970000 29.970000]fps
[avfoundation @ 0x7fd349000000] 1280x720@[25.000000 25.000000]fps
[avfoundation @ 0x7fd349000000] 1280x720@[23.999981 23.999981]fps
[avfoundation @ 0x7fd349000000] 1280x720@[14.999993 14.999993]fps

Is it possible to change the frame rate? Or can it possibly be an other issue?

Does it work when you explicitly set the frame rate to 25 in stream.go like this?

fmt.Sprintf(" -framerate 25") +

No still getting the same message:

default: Input/output error

I receive this message when opening the Home app and looking at the camera component.

Had a second look at it and got it working (still get the above messages though). I changed the following to stream.go:

Added the line you mentioned:
fmt.Sprintf(" -framerate 25") +

Slashed out:
//fmt.Sprintf(" -framerate %d", s.framerate(video.Attributes)) +
//fmt.Sprintf(" -framerate %d", video.Attributes.Framerate) +

Yes I also saw this, I tried changing it to 25 but did nothing so left it at 30.
Can confirm that it is working on a MacBook Pro 13" early 2011, however I do not have sound.
But if I read it correctly it is not yet implemented?
