    Issues in Skype with analog Cyber Acoustics headset and USB Rocketfish cam NBCAM

    Okay! Should I update to 11.10 like update manager insists I do?

    Initially, I had no problem with audio out, but some of the fixes given in a thread that I started eradicated my audio out in Skype as well. My audio and video work well outside of Skype.

    I have posted another mpost under here with detailed info from an alsa script:

    wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh

    PLease check the second post and please tell me what I should do. Thank you



    My cam is a usb rocketfish and my headphone is RCA (it connects to the headphone and mic jacks of the computer).

    Codec: Realtek ALC861
    Codec: LSI Si3054

    The properties of the launcher icon is ... bash -c 'LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype'

    I am told in the other thread that I should install libv4l-0:i386, but I could not find this in synaptic not could I install it in terminal.

    Maybe I need to install the default audio and video settings, if that can be done?

    I have been told that pulseaudio and skype don't seem to work well, so I tried to switch to use the alsa plug=ins in the multimedia selector (that is what I have set it to). But, in Skype, there is no alsa option in the audio. I am pretty sure that skype should be using Alsa, but then I KNOW NOTHING, so bear with me. I hope this kinds of make sense to you!

    Thanks for your help.

    Re: No video out and audio out in Skype

    In my experience, every release improves the handling of sound on notebook computers. At least try a LiveCD or LiveUSB of the latest release. Multisystem can produce a "persistent" USB drive, so you can install programs such as Skype.

    I have read many horror stories about upgrading. I always do a fresh install, which is a lot easier if you have separate root and /home partitions. I also have excellent backup, thanks to a large USB hard drive.

    EUREKA (for the audio setting)!

    I found it! See attachment #4 for the answer!

    Still no video though! RRRR!

    I suspected that if the default did not work in audio, then the Intel ALC861 analog (which I saw in the diagnostics).

    Oh! Thanks, Gord! Right?

    I actually couldn't handle not upgrading and did it. I made sure that I had updated Natty first though, as I think I read that this could be an issue.

    It went well, but it was long: 6 hours.

    I was hoping that it would solve the video and audio issue, but I think --during the install-- I chose the wrong choice (of basically keeping my system as it was before). The language was a bit unclear (I think it talked about "maintainer version or not"! I assumed it meant "maintained"! Then, I tried to insert D, but it did not, and it used Y, instead, when I clicked somewhere else. SO, I wanted to try a fresh version, but the "forces" did not let me.

    BTW, my video and sound outside of Skype works!, but still no luck within Skype!

    I have attached a few screenshots to let you know where I am at.

    I did the alsa test again and the dsmeg which returned this, respectively:

    Check at http://www.alsa-project.org/db/?f=e3...5c4db2bd21007c

    (I noticed that it returned this:

    But, it seems to indicate that there is audio out of my camera, but there isn't. I have a regular audio.mic jacks combo (Cyber Acoustics headphone/mic headset) which is inserted into the front headphone/mic jacks). Maybe that is the issue. Could that be?

    Re: No video out and audio out in Skype

    According to this web site: http://www.rocketfishproducts.com/pr.../RF-WEB2C.html
    the Rocketfish has a microphone.

    When you run Cheese, and select Edit/Preferences, I assume there is a greyed-out "video" entry which says /dev/video0? It's possible you need to run Skype by entering the Terminal command:
    bash -c 'LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype'

    Hi Gord,

    Ah! I think we are getting somewhere. I wish I could be a bit more perspicacious though! I am really sorry, but when you think one way, it is sometimes hard to deprogram!

    Thanks for helping me out. Well! You made me doubt myself, which is good, because upon searching this webcam, I found out that indeed it has a microphone. I did not know, but when I looked at it, it had a little hole, which indicated to me that maybe it had. The specs conforms this.

    http://www.rocketfishproducts.com/pr.../RF-NBCAM.html

    I do have that command, with an extra ' at the end though. That isn't working. I will try without the ', but I am pretty sure that was a typo. Right?

    So, the headset mic. is working now. Not sure about the cam mic, but I suspect it could if I were to select the appropriate item in the audio settings in SKype which might fix the webcam video. I am not too sure how those things work. Maybe things will work if I leave the analog headset out. I will experiment and get back to you.

    Yes! In the video settings there is USB20 Camera (/dev/video0)

    I do use the icon on my desktop which has the command, as specified. I then enter my password and then I am in. But, still, no video out.

    I found a read me file in a Microdia folder. It looks like this is the Rocketfish cam (as indicated above: Bus 001 Device 002: ID 0c45:6288 Microdia PC Camera with Microphone (SN9C202 + OV9655), as returned by lsusb)

    Here is what it states.

    "SN9C20x USB 2.0 Webcam Driver
    ==============================

    This driver is essentially a fork of the Syntek Webcam drivers for Linux
    by Nicolas Vivien, specifically to accomodate SN9C20x chipset based Webcams.

    The driver currently supports the latest version of Video For Linux i.e
    V4L2. V4L1 is deprecated, and applications like Camorama that use only V4L1 will
    only work with libv4l ("v4l1compat.so").

    This driver currently supports Skype v2.x, Ekiga v2.x & even aMSN

    Warning :
    The SN9C20x USB 2.0 Webcam Driver for SN9C20x chipset based Webcams is
    currently under development. Using this driver can result in damage and data
    loss to your system. Use this driver only if you know what you are doing.

    --------------------------------------------------------------------------------

    1. Requirements

    1.1 Kernel module

    To compile the driver you need :
    Kernel 2.6.22 or higher
    Kernel headers
    make
    gcc

    1.2 Documentation

    To compile the documentation you need :
    doxygen
    graphviz

    1.3 Decoder

    Most video applications do not support the image encoding SN9C20x-based
    webcams offer. Such applications need to have the image stream converted
    for them. This can be done using "libv4l", which is pre-loaded between the
    application and the video resource and translates the image stream into a
    usable format.

    Most distributions offer precompiled packages. If yours does not, the
    sources are available here :
    http://freshmeat.net/projects/libv4l/

    Consult libv4l's README for usage details.

    --------------------------------------------------------------------------------

    2. Available Packages

    There are packages for various distributions available here :
    http://repo.or.cz/w/pkgmicrodia.git

    --------------------------------------------------------------------------------

    3. Compilation

    3.1 Kernel module

    To build the kernel module ("driver") :
    $ make
    (This will create the kernel object file called "sn9c20x.ko".)

    3.2 Documentation

    To build the documentation :
    $ make doc
    $ make cleandoc

    --------------------------------------------------------------------------------

    4. Testing

    To load the driver, follow these steps (as root) :
    # modprobe videodev
    # modprobe compat-ioctl32 // Only required for 64-bit Linux OS
    # make insmod

    Note: Most applications require libv4l for image format decoding (see "1.3
    Decoder"). Consult libv4l documentation for full usage details. Here is an
    example for a common usage :
    $ LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so mplayer tv:// -tv \
    driver=v4l2:width=640:height=480:fps=25:device=/dev/video0 -vo xv

    --------------------------------------------------------------------------------

    5. Installation

    $ strip -g sn9c20x.ko
    And as root :
    # cp sn9c20x.ko /lib/modules/`uname -r`/kernel/drivers/media/video/usbvideo/
    # depmod -a

    --------------------------------------------------------------------------------

    6. Usage

    We recommend using v4l2ucp to adjust and improve image quality.
    http://sourceforge.net/projects/v4l2ucp/

    We are also developing our own GUI, available here :
    http://repo.or.cz/r/guimicrodia.git

    --------------------------------------------------------------------------------

    7. Status

    The kernel module is currently under active development.

    The full list of supported webcams can be found here :
    http://groups.google.com/group/micro...project-status

    --------------------------------------------------------------------------------

    8. Contact

    To request support, please contact us on Microdia Mailing List :
    https://groups.google.com/group/microdia/
    microdia@googlegroups.com

    --------------------------------------------------------------------------------

    9. More Documentation & References

    All documentation and references for microdia webcam driver can be found at
    http://groups.google.com/group/microdia/web

    Latest version of this driver is usually available at the following location
    http://repo.or.cz/w/microdia.git

    --------------------------------------------------------------------------------

    10. Licence

    SN9C20x USB 2.0 Webcam Driver is distributed under the GPL licence version 2
    or later (GPLv2+)."

    I hope this helps!

    Re: No video out and audio out in Skype

    If you insert this line of code after right clicking on the Skype icon and going to properties and entering it in the command section, then the test in the video section of Skype will work for the Rocketfish USBCAM.

    sh -c 'LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so /usr/bin/skype "$@"'

    I will test in a few days to see if it is stable in a call, as I have had many instances of video-in crashing and dropping after a few minutes of use. I suspect my video card cannot handle that much work. Some people claim that Compiz and Cairo-dock might overload the video card (which, in my case, is a cheap embedded intel).

    I will get back to you soon.

    Re: No video out and audio out in Skype

    I've found that Skype places heavy demands on the CPU. What one does your computer have? (It runs just fine on my Phenom II X2 at 3.1 GHz, but that's a fairly powerful processor.)

    Ya! I think you are right!

    I have attached a screenshot of my system processes with % of CPU. I am surprised to see 4 or 5 Skype (albeit sleeping) processes being reported, consuming significant % of CPU share when I have NOT opened Skype! Is this normal?

    I also notice that with just Skype opened in a test mode configuration, I have peeks of 90% CPU load (average is 70%, range is 40 to 90%). When I open Skype and Chrome, the test area does not work all the time (looks like the video card is overloaded), but does work 2/3 times (see last attachment #4). Just Chrome opened returns maxes of 80% and lows of 40%. Is there any way (apart from not using Chrome) to reduce the CPU load and ensure that video + audio in Skype is not going to overtax the system (apart from buying another computer)! Would more ram help?

    I restested things in a call and here are the results:

    If you insert this line of code after right clicking on the Skype icon and going to properties and entering it in the command section, then the test in the video section of Skype will work for the Rocketfish USBCAM.

I suspect my video card cannot handle that much work. Some people claim that Compiz and Cairo-dock might overload the video card (which, in my case, is an cheap embedded intel).

    After testing it in a call, the video lasted maybe a few minutes. It worked, but then I couldn't get it back after many trials. I could get the video feed from the other person though! I noticed that I had loads of Chrome programs and other stuff cluttering in my system, grabbing a share of the CPU, which shot up faster that to 100% a few times. The test video did not work either. I then rebooted it and tried the video test in Skype and it worked again. I noticed that I had way fewer stuff grabbing a share of my CPU. I will try next time to do a fresh boot and not open any other app and see if that makes a diff. I suspect it will.

    Not sure exactly what I have in terms of integrated graphic card because I see so many different #s below. Maybe you would know. I have included in the attachment the specs of some, but not sure which is mine. I know I have a core solo, but there are many like that.

    So, do you think the graphic card could be struggling during Skype calls, which might explain why video calls crashes, but not just audio calls? Do you think the CAiro dock/Compiz issue is something I should investigate? Do you think it could be a bandwith issue? I have up to 256 Kbps upload speed.

    Re: No video out and audio out in Skype

    Your computer is roughly equivalent to today's netbooks, and videoconferencing in Skype has heavy demands, perhaps more than the CPU and video card can handle over a long call.

    If you want to see what is using the CPU, I suggest you open a terminal and enter the command top, which uses less resources than System Monitor.

    How old is your machine? The command sudo lshw > myconfig.txt will generate a text file with complete details about your computer. In particular, it will show the date of the BIOS, which is really your computer's "birthday."
