Mplayer detects but not Cheese

[vubuntu]

Hiya,

My webcam has failed to work since I upgrade to Ubuntu 9.04 (kernel
2.6.28-11). I did everything again from scratch and now only Mplayer
detects and shows webcam images. Cheese shows neither "No wecam" nor
"With webcam". Please note it worked with the previous kernel.

I attach this log below. Please tell me what has gone wrong. Thanks.

Have you tried starting cheese using LD_PRELOAD to make sure libv4l is
getting loaded?

I don't actually think thats needed in jaunty since interpid had the
gstreamer libraries linked against libv4l and i don't think that has
changed in jaunty but it shouldn't hurt either.

If you have done that and it does not help try loading the driver
module with the following

# insmod ./sn9c20x.ko log_level=15

This should turn on full debugging output. After starting cheese your
dmesg log should contain a bunch more infromation regarding what the
driver is trying to do.

[vubuntu]

Thanks, Brian

The problem is still there. I follow your instructions, and here is
the ouput:

root@vietkhoa-laptop:/home/vietkhoa/microdia# insmod ./sn9c20x.ko
log_level=15
insmod: error inserting './sn9c20x.ko': -1 File exists

dmesg produces an output which does not fit here, so I just copy the
part that I think is involved

Ok that log does not actually have the debug information in it.

You need to make sure to remove the sn9c20x.ko module before inserting it again.

# rmmod ./sn9c20x.ko
# insmod ./sn9c20x.ko log_level=15

Also best way to capture the necessary parts of the log i need to look
at is do the following
# tail -f /var/log/syslog > ~/debug.log

Now in another terminal window start cheese up and then you should
have a file called debug.log in your home directory that contains all
the debugging information needed.

Hi Brian,

> # tail -f /var/log/syslog > ~/debug.log

does not work with mine (it gets stuck in Terminal, or I did something
wrong...), so I have no "debug.log" file in Home. Anyway, here is the
output of dmesg that I think contains more info:

[Brian Johnson]

I'm not seeing anything immediately wrong with this log in fact as far
as i can tell it actually started the stream properly. When running
cheese what actually happens? is anything at all displayed in cheese?

One thing you could try is turning on jpeg support

# rmmod ./sn9c20x.ko
# insmod ./sn9c20x.ko jpeg=1

I don't really think it will change anything but i'm not sure what
else is the issue i know other people that use jaunty and tell me
cheese works fine with this driver under jaunty.

[vubuntu]

Thanks for your time, Brian.

Do you think new kernel (2.6.28-11) has blocked microdia driver from
working?

Cheese does not show anything special. I does not show "No webcam"
message and in its preferences, it detects my webcam with full
technical information but with no resolution options.

I'll make more tests to see if it works, and will let know know the
result.

I experience the same on my Jaunty system with the sn9c20x module from
the nickel62metal ppa (srcversion: 7E66E40CB260AB87B30BA25 if that helps).

Doesn't work for me either.

Could it be, that it's a 64-bit issue? At least, IÄm running a 64-bit
system. Maybe I could try a 32-bit jaunty live-CD with the same driver
and see if that works.

Regards,
Jochen

Unfortunately, I wasn't able to try the driver with a Jaunty live-CD as
it fails to boot on my computer.
Vubuntu, are you having the cheese (or rather gstreamer I guess)
problems on a 32- or a 64-bit machine? In the latter case, could you try
if it works with a 32-bit Jaunty live-CD?

Regards,
Jochen

[vubuntu]

Hi there,

I haven't got the 32bit version available to test. You may be right
that it seems to be a problem with the 64bit one only.

Or it could be that of Cheese which can't catch up with new video
stream in Jaunty.

I don't think this is a cheese problem (Uh, that sounds strange...). I
think, it is more likely to be related to gstreamer. AFAICT, cheese uses
gstreamer to acquire the image, which would also explain, why the webcam
works for example in skype, ekiga and mplayer which do not seem to use a
gstreamer-based backend.
Also, the video input preview in gstreamer-properties fails to show the
image from the webcam but only displays an error message saying "Video
for Linux 2 (v4l2): Could not negotiate format"

Regards,
Jochen

Yes cheese uses gstreamer for its v4l interface, so yeah the issue is
propably not directly related to cheese but either gstreamer or
libv4l. It also appears it may be 64bit related somehow since i have
had reports of our driver working just fine using cheese on jaunty but
i think the person was using 32bit rather then 64bit

[vubuntu]

Thanks, Jochen - Brian.

Yeah, something problematic with gstreamer and/or libv4l in the 64bit
version sounds more possible.

In my case, only MPlayer can show webcam images. Neither cheese nor
skype can do the same despite detecting the name of the webcam. Other
webcam applications say NO, either.

I also notice a strange thing which I suppose a problem, i.e: after my
laptop restarts, Kernel 2.6.28-11 does not remember the microdia
installation and configurations whilst Kernel 2.6.27-7 does.

Anyway, now I have to boot into Kernel 2.6.27-7 to use my webcam
with... a little reluctance :-)

But you guys here have done a great job. IOU 4 that.

Cheers,

You have to compile and install sn9c20x.ko for every new kernel if you don't
use DKMS.

Hi, I mean I have done those. I even have DKMS installed.

What I don't understand is why it works well in 2.6.27-7, but has
problems in 2.6.28-11 (note: compiling and installing microdia driver
has been done successfully)

[Brian Johnson]

If you are compiling the kernel from our repository. Do the following
after compiling the driver to load it every time you boot.

# sudo cp ./sn9c20x.ko /lib/modules/`uname -r`/kernel/ubuntu/misc/media
# sudo depmod -a

Well, your patch 0002-Implement-ENUM_FRAMESIZES.patch fixes the issue
for me. I've got the cam working in gstreamer-properties and cheese.

[Brian Johnson]

Cool, so implementing the enum_framesizes ioctl seems to fix the
issues with gstreamer not working properly.

vubuntu, can you confirm if this also works for you as well?

[vubuntu]

Oh, it works? Good to hear.

Sorry for my stupidity but I can't find the patch "0002-Implement-
ENUM_FRAMESIZES.patch" and don't know how to patch.

Is it somewhere in "Fix bug when compiling on 2.6.29 or greater 64bit
kernel"

As far as I understand, the patch is included in the source code but I
fail to find it.

Anyway, when running gstreamer-properties, I get this log:

What do I do wrongly?

[Brian Johnson]

Wrong patch. Its called 0002-Implement-ENUM_FRAMESIZES.patch and is
located in the follwoing thread

http://groups.google.com/group/microdia/browse_frm/thread/972a940d80ee4eab

[vubuntu]

Dinh Dong, Brian. It works with the patch applied! Cheese now can show
the webcam images. Good job!

But it turns out to have another problem: Skype can detect but cannnot
show webcam video output.

Here is the log when I run "LD_PRELOAD=/usr/lib/libv4/v4l2convert.so
skype", and test the webcam:

Ok glad this patch seems to sucesfully fix the issues with cheese.

As for skype it looks like you have a small typo
/usr/lib/libv4/v4l2convert.so -> /usr/lib/libv4l/v4l2convert.so

The important line is this errorline:

ERROR: ld.so: object '/usr/lib/libv4/v4l2convert.so' from LD_PRELOAD cannot be
preloaded: ignored.

It can have several reasons:
1. There is now v4l2convert.so in the given location.
2. The given v4l2convert.so is not compiled for 32-bit machines. Skype is only
shipped as a 32-bit binary and will therfore not link with a 64-bit library.

Just info that this patch also works with:

0c45:624f Microdia PC Camera (SN9C201 + OV9650)

It works perfect both with GStreamer and Skype. Oh, and also with
GYachE!

Thank you so much guys ...
