Hi,
dnf install xawtv
Then use the streamer command line to try to grab a picture then a video. Check http://www.tldp.org/HOWTO/Webcam-HOWTO/framegrabbers.html
On my Fedora 23 I have to unload the facetimehd (modprobe -r facetimehd) then reload it (modprobe facetimehd) between EACH try. the camera initiates only ONCE, then I have to cycle the module.
I could get a picture, and I tried a 5 seconds video, but only got like 3 frames. Hey, considering we're early to the party, it is great!!!

Also as per patjak's comment in #17 try mplayer and run player tv:// It works for me. Looks like Cheese is the culprit of the camera issue.

I found out, that cheese
(and gnome-contacts
too) don't display a corrupt image if the driver is limited to the maximum hardware resolution:
#define FTHD_MAX_WIDTH 1280
#define FTHD_MAX_HEIGHT 720
But cheese
is still unusable (as the picture grab feature in gnome-contacts
too).

Haha it looks some Linux apps have issues with very high resolution webcam.
Apple faced the same issue a few years ago. Lowering the resolution indeed
"solves" the issue with cheese. The v4l2 interface of the driver is still a
big shaky but it 's already great job.

@xgnata How do you force driver to load lower resolution ubuntu 15.10?
from facetimehd.
I've lowered the max resolution in the driver to 1280x720. The ISP might be able to handle higher resolution but other components probably can't. Does this fix the issue?
from facetimehd.
Yes it does solve the issue at least with cheese. Thanks.
According to the Apple website (http://www.apple.com/macbook-air/features.html) it is a 720p FaceTime HD camera". Therefore limiting the resolution to 1280x720 seems to be the right thing to do.

Great, I'll close this for now. Reopen if needed.
