Hello,
I verified this issue again on 201203-10656
by following these steps:
1. Install Ubuntu, boot to desktop, install fswebcam
2. run "fswebcam --save OK.jpg"
3. run "fswebcam --save OK.jpg -D 1"
This problem still exist on:
3.5.0-44 (12.04.2 + update)
3.8.0-29 (12.04.3)
3.12.0-7 (daily-live Trusty)
For all of these kernels,
On step 2,
picture cannot be taken, the webcam LED will be lit for a while
and the following error message pops-up:
"Timed out waiting for frame!"
"No frame captured"
On step 3,
webcam LED flashes and picture can be taken correctly.
Also, I have it tested with 3.10-rc7 again for consistency.
I would like to rephrase what I tested for v3.10-rc7
On this kernel, step 2 works fine for one time after boot,
but if you do it again, it behaves like other kernels
Step 3 also works for 3.10-rc7
Along with the -v tweak that I mention earlier,
I think it's the delay time that make the difference on this specific Rev. of
device.

Title:
Camera - Microdia [0c45:648d] camera_test is unable to take still
pictures
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
CID: 201203-10664 Dell Inspiron 7420
On this system, the camera_test script is able to display video capture form
the built-in camera.
But it's unable to display a still image and multiple resolution images, the
file size of temporarily stored file is zero.
Causing the image viewer complain about "Could not load image" (screenshot
attached)
Or "Failed to validate image" for multiple resolution images test case.
I tried to get more information from the script by adding "-v" to
fswebcam command like this:
def _still_helper(self, filename, width, height, quiet, pixelformat=None):
"""
Captures an image to a given filename. width and height specify the
image size and quiet controls whether the image is displayed to the
user (quiet = True means do not display image).
"""
command = ["fswebcam -v", "-S 3", "--no-banner",
"-d", self.args.device,
I didn't get any extra imformation, but both the "still" and
"resolutions" test cases work fine with this.
