Hi,
recently I bought an Acer Travelmate 5720 Notebook which
comes with a build in webcam. I installed Kubuntu Feisty and
was able to access the camera and grab some images:
ffmpeg -an -vd /dev/video0 -s 480x320 -sameq -vcodec mpeg4
"test.avi"
Linphone can't though. All it does is (when invoked
"verbose")
ortp-message-oRTP-0.14.0 initialized.
ortp-message-Registering all filters...
ortp-message-Registering all soundcard handlers

Then, the video screen stays just black. What a pity!!
What's wrong?

Hi Conrad,
You are not the only one having this problem.
What is the driver name of the camera ?
It is perhaps a bug in the driver, but it can surely be
workarounded since
ffmpeg succeed to talk with that driver.
I need to dig into the driver source to understand what that
protocol error
means, that's why I'd like to know the driver name.
Thanks
Simon

Hi Simon,
... I like the support you're providing. We can rely on that
every
request is answered - even if there is pressure on your side
and it
takes a couple of days - it's not forgotten 
The driver according to lsmod is uvcvideo (see my lsmod
below). This
happens when I do a --verbose is this one:
ortp-message-v4l_start: open, fd=11

I looked at the driver code but it never returns
"Protocol error". The error
might come from the lower layers of linux usb support.
I'm going to ask to uvc mailling list...

Hi,
I'm the maintainer of linphone (video chat tool), and I use
uvcvideo driver
without major problems every day, however I receive many
complaints of users
having "Protocol error" (EPROT) returned by the
VIDEOC_STREAMON ioctl.
The bug is probably in my code, but if you have any hints
about the meaning of
this error, you're welcome !
Thank you very much
Simon

Hi,
Thank you for the advice. I wonder if the problem isn't
related to threads,
since the grabbing process is done within a dedicated thread
in linphone.
Furthermore, the init phase (open, ioctl to setup format and
size) is done
from one thread, while the mmaps, stream-on and QBUF and
DQBUF are done by
another thread.
However the instructions are serialised (the
mmap/stream-on/Q/DQ) occurs AFTER
the init phase.
But I wonder if it cannot confuse the usb stack.
The last complain was from somebody using an "Acer
CrystalEye" camera.

Yes it is possible. I plan to do it as soon as I can.

Hi Conrad,
My only hypothesis concerning this problem is that the linux
usb stack does
not like that linphone makes call to it using 2 different
threads (through
the uvc driver). I plan to rework the grabbing component to
get only one
thread talking with the driver.
I experience also very strange problem with that uvc driver
with pictures
being splitted or very unstable and ffmpeg complaning of
corrupted mjpeg
bitstream. I think all this is related to the threading
design used in
linphone.
Concerning windows vista, I know there are several problems
but unfortunately
I could never have a try myself. A friend of mine is going
to give me its PC
with vista installed to get a chance to solve all those
problems.
