Re: [Linux-uvc-devel] Problem with wireless webcam from Maplin
Hi, Have you tried any other software besides cheese? (guvcview, luvcview,...) Regards, Paulo 2011/11/23 Antonio Roberts anto...@hellocatfood.com: I recently bought this wireless webcam; http://www.maplin.co.uk/2.4ghz-wireless-webcam-388087 . I'm having trouble getting it to work on Ubuntu 11.04. I ran lsusb and got the folowing information about the device: Bus 006 Device 003: ID 0416:a91a Winbond Electronics Corp. I did a Google serach for the device ID and the Linux UVC website (http://www.ideasonboard.org/uvc/ ) informs me that it matches the LogiLink Wireless Webcam (so Maplin probably just rebranded this!). What this website states is that this device should work, which it doesn't. The problem I'm facing is that I don't get any actual video being streamed or shown. The built in microphone works and, when running Cheese, when I press the camera button on the webcam itself the software recognises that the button is pressed. On that note, when running cheese from the terminal with this webcam attached I get the following error: libv4l2: error getting pixformat: Invalid argument libv4l2: error setting pixformat: Input/output error Any help is appreciated -- anto...@hellocatfood.com http://www.hellocatfood.com ___ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel ___ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
Re: [Linux-uvc-devel] Logitech QuickCam Sphere AF not working
Hi,
I have my logitech sphere up and running with a 64 bit 3.0 kernel.
All controls are working including pan/tilt/ and focus.
In ubuntu at least you can't cold plug the camera, or uvcdynctrl won't
get triggered.
The easiest way is just to rmmod and then modprobe uvcvideo, this will
get everything working.
At least for me it did.

Hello,
my webcam used to work almost fine with older kernels, but failures have
become too frequent since 3.0:

The camera is nearly unusable right now. The video stops soon after an
application that reads it (e.g. cheese) is started. There are numerous error
messages related to uvcvideo in dmesg. Examples follow:
uvcvideo: Found UVC 1.00 device unnamed (046d:0994)

uvcvideo: Failed to query (GET_MAX) UVC control 4 on unit 2: -110

All these mesasges were observed on a 3.0.7 kernel when plugging/unplugging
the camera a couple of times, both with and without a hub between the
computer and the camera. (There was still the same problem in all cases.)
BTW, is there any possibility to get the motion and autofocus features
running? They used to work fine on 32-bit kernels using the
uvcdynctrl/guvcview combination, but there seems to be *no* way to make it
work on my 64-bit machines. It simply doesn't work, no matter what I try. Is
there an updated howto for this?
A piece of advice would be very heplpful. :-)

[Linux-uvc-devel] guvcview moves to sourceforge
Hi all, Just dropping a line to inform you that guvcview has moved to sourceforge: project page: http://sourceforge.net/p/guvcview/home/Home/ home page: guvcview.sourceforge.net This change was prompted by the closing of berlios on 31-12-2011, the lack of funding has forced them to shut-down their services, so all projects were invited to move to a new service provider. My decision was to move to sourceforge since they run pretty much the same services as berlios. On a side note I just released version 1.5.1 it adds support for gtk3 and improves support for libavcodec 7 (the prior versions had most codecs broken under ubuntu 11.10) Best Regards, Paulo ___ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel

Hi, guvcview detects some sync issues, it seems although you select 30 fps, for that resolution (1280x720) your hardware is just not powerful enough to decode the MJPG stream and re-encode it with whatever coded you are using. Some solutions: -reduce the fps -reduce the resolution -try using a less resource demanding video codec (MJPG will save the video stream directly to disk, no compression is done in this case, but it generates a huge file if compared with any of the mpeg codecs) -use the matroska container instead of avi, it is much better since individual frames are timed stamped.

Re: [Linux-uvc-devel] Microsoft Lifecam Cinema
Hi, if you are using any of the mpeg4 codecs, you will need a rather powerful cpu for encoding at high frame rates, specially at any decent resolution. As an example I don't have any special problems with the following configuration: device input: MJPEG 800x600@25 fps video codec - mpeg 4 - avc (h264) audio codec - mpeg2 container - matroska 2.8.38 - 64bit kernel hardware: intel QuadCore 2,8 Ghz (45nm), 4 GB ram but if I increase the input to 30 fps I'll only get about 28 when encoding. If you changed the codec to MJPEG, and still have issues then there could be something wrong with your setup, is the audio OK except for the sync issues? As for the sync issues, do you get the audio before the video or vice versa ? Regards, Paulo 2011/9/7 Steffen stes...@googlemail.com: Hi Paolo, Thank you for your answer!

Re: [Linux-uvc-devel] Microsoft Lifecam Cinema
Hi, Well if the audio comes first it means you are dropping audio frames making audio capture shorter than video, this usually means issues with the audio source, you seem to have confirmed this by changing to another mic and verifying that the recorded video works fine in that case. There could be several reasons to why these audio frames are dropped, from hardware/firmware to low level usb issues, does your dmesg output prints anything related to snd_usb_audio module? Also are you sure cheese is using your camera mic? For what I understand it always uses the system default audio input (in your case is the pulse server virtual alsa device). Regards, Paulo 2011/9/7 Steffen stes...@googlemail.com: Hi Paulo, I am using a quite powerful PC i5 2.8 8 Gig RAM, ... and even with lowest settings, 640 x 480 the result is the same. The audio always comes out first. If I choose a different audio source like my other Logitech C525 or Lifecam VX-2000 the recording of the Lifecam Cinema is fine and even syncron to audio.

Re: [Linux-uvc-devel] Logitech C910 camera problems
Hi, The flag is think is UVC_CONTROL_AUTO_UPDATE and in the case of extension controls you really need to set it to disable control caching, this is specially evident for control like pan/tilt, that behave badly if this flag is not set. see: http://www.spinics.net/lists/vfl/msg38717.html in the case of exposure however this was never a problem. in kernel 3.0 the auto exposure menu only reports the valid menu values (2) instead of all 4, this was a problem for tools like guvcview that didn't expect this. I've now fix it (1.5.0) and it is working fine, you also may want to test some other control tool like yavta instead. Regards, Paulo 2011/8/12 Philip Gladstone phi...@gladstonefamily.net: In doing some digging, it also appears that the settings that I am interested in are also being cached by the driver, so I am not really getting the right values. I suspect that for UVC_CT_EXPOSURE_TIME_ABSOLUTE_CONTROL, UVC_PU_GAIN_CONTROL (at least), I want the UVC_CTRL_FLAG_AUTO_UPDATE set. This won't (I doubt) improve the exposure of the image, but it will improve the reporting.

Re: [Linux-uvc-devel] 3.0 - exposure settings.
Hi, guvcview had a little problem when handling menu control indexes, it was using the combo box index instead of the real control menu index. This should be fixed in svn (svn://svn.berlios.de/guvcview/trunk) if you care to test it. This worked fine for sequential menu indexes, but this specific case revealed the bug. In any case I can't see how it turned a menu combo into a check box, It just hasn't that type of code.

Re: [Linux-uvc-devel] luvcview does not record video in avi
Hi,
2011/6/10 JITENDRA SINGH narukajsi...@gmail.com:
Hi Paulo,
Thanks a lot, I tried using IYUV 4cc before your reply, now using YUY2 4cc
code luvcview is recording the yuv file but its quite large as compared to
one recorded by ffmpeg. I understand that ffmpeg encodes yuyv frames
resulting in smaller mpg file.
YUYV is a uncompressed format (16 bit per pixel), it will always
produce much larger files if compared with any compressed.
I just need litle advice, I want a survillance app on arm arch, but would
like to use luvcview to record and not ffmpeg as luvcview is gud small pkg,
in that case should I go for a mjpg based webcam such as C905?
Just can't find performance comparison of yuyv vs mjpg based webcams and
apps(considering mjpg/yuyv encoding is done in webcam only)...hope you put
some valuable words !!
in terms of performance, streaming in yuyv or mjpg on a usb2
connection makes no big difference although you should be able achieve
better fps with mjpg at higher resolutions.
YUYV is more limited due the higher usb bandwidth needed.
Regards,
Paulo
Many thanks,
Naruka

Hi,
The 4cc code for YUYV is YUY2, at least this is what I use for
guvcview and it works with most video players.
So just use the same luvcview code but replace the 4cc code from MJPG
to YUY2 in the case of a YUYV stream format.

just use that when streaming in yuyv and the file should be ok

It identifies itself as: Laptop_Integrated_Webcam_2HDM, usbid: 0408:2fb1. This is built in to a Dell XPS-15 (L501X). The uvcvideo module works, but the video stutters and has some distortions, even at low resolutions and frame rates. With the Camera Output set to MJPG (in guvcview) Ignoring empty buffer ... messages occur with most glitches. I would say the camera is not returning the full frame (or maybe empty ones) for same reason. If the output is set to YV12, the errors look like: VIDIOC_DQBUF - Unable to dequeue buffer : Input/output error Error grabbing image libv4l2: error converting / decoding frame data: v4l-convert: error parsing JPEG header: Not a JPG file ? YV12 is a format returned by libv4l, and it's obtained by decompressing the MJPG stream, so in fact the camera is still in MJPG format like above. With cheese, the video preview looks ok, but video capture is unusable - the video stutters badly at low resolution, and the capture hangs at high resolution (the program doesn't hang, but after a couple of frames no more get captured). Probably the same situation as above (incomplete or empty frames) You should also increase uvc video verbosity and check dmesg for errors.

Hi, I've had a look and it indeed there is a focus control. Considering that by default it is set on 0 (and it was set on 0 during operation), does this mean that it is on auto?

Re: [Linux-uvc-devel] Footage of objects in motion recorded from webcam is blurry
Hi, 1. Would this be fairly specific to the Logitech QuickCam 9000, or is a more generic issue with webcam sensors? Neither, you just need to lower exposure time. 2. Are other webcams better in this respect? I don't think so, you can control exposure quite easily with this cam. 3. Can I use any of the UVC features to tweak the driver parameters in order to force sharper images of objects on the move? Yes, just set exposure mode to manual, and tweak exposure absolute, also remember to disable exposure, auto priority. You should also use the highest fps possible (30 fps I think) 4. Is this to do with the auto-focus of the camera, and can I turn it off or peg it in software at a certain value, to improve things? Yes, use uvcdynctrl (command line) or guvcview (gtk) (guvcview --control_only will let you use your program along side it) Regards, Paulo ___ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel

Hi, What is the proper way to disable the LEDs on the Quick Cam Pro 9000 and You must use logitech extension controls for this, you can use uvcdynctrl from libwebcam (command line) or guvcview (gtk), you must be root to add these controls to the driver (libwebcam installs a udev script to handle them automatically). after adding them to the driver they will display like regular v4l2 controls. For the pro9000 If I'm not mistaken you have focus control, led control, led frequency control and possibly video processing control (raw bayer). other Quick Cam Pro cameras? (I have a 4000 as well).

The values for min/max bit rate are (correctly) calculated from the frame intervals and the buffer size. The uvcvideo driver doesn't use the dwMaxVideoFrameBufferSize field to compute the required bandwidth but queries the device at runtime instead. You can enable the UVC_TRACE_VIDEO trace flag to get the driver to print the bandwidth requested by the device to the kernel log. Typical JPEG compression gets down to 1 bit per pixel, and 2 bits is very unusual. What I want to know is what the impact would be of defining a new QUIRK that overrode the frame buffer size for compressed frames and calculated them at (say) 2 bits per pixel?

OK, So the camera claims to support 640x...@30 fps, but I guess you need to manually set exposure for that. Just set the Exposure, Auto control to manual and adjust Exposure (Absolute) to a level where you get the 30 fps ( the image will probably get very dark, in this case you will need to use a brighter light source).

From your explanation I understand that having many buffers will be helpful in case of streaming as we do not want to loose frames.

If for some reason your application can't dequeue the buffers fast enough the driver will be forced to drop frames, with a larger buffer count you will have a comfort zone, even if at some point your application can't catch up with the hardware frame rate, you will always be able to recover later without losing frames. Of curse even this may not be enough if the application is to slow, but if the cpu load only increases momentarily then having more than one buffer will be very advantageous.

Hi, No usd ID is needed for the uvc driver. UVC cameras identify themselves as such: http://www.ideasonboard.org/uvc/faq/ ID's found on the driver code are merely used for passing driver quirks for some cameras with known issues. So first check if your camera is uvc compliant (see previous link), if not then I would advise you to look at gspca code and maybe try to write a subdriver for your specific device. the following docs may help: http://www.linuxtv.org/wiki/index.php/Developer_Section Best Regards, Paulo ___ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel

Hi, OK, if I now start [ command 'luvcview' ]-- luvcview 0.2.4 SDL information: Video driver: X11 A window manager is available Device information: Device path: /dev/video0 Stream settings: Frame format: MJPG Frame size: 320x240 (requested size 640x320 is not supported by device) Frame rate: 20/1 fps (requested frame rate 30 fps is not supported by device) OK, I get 2-4 fps now I can get snapshoots and the video, but if I play the Video, it is arround 10-15 times faster as the original... So, why doees luvcview not set the framerate correctly in the video? I think luvcview uses the frame rate you requested (or in this case 20 fps as is the value suported by the device) but if you only get 4 fps then the video will play a lot faster. Try other capture software, like guvcview, cheese or vlc. Guvcview will set an average fps for avi files and in the case of matroska, frames are timed stamped so variable fps should not be a big issue.

I have not requested it... and IF I do it, I get:

Yeah, I need variable fps, but I would prefer vlc or something like a

can use whatever program I wan to view the stream.
vlc is your best option for this.

Re: [Linux-uvc-devel] Support for the Logitech C310 USB HD Webcam
Hi, All new logitech models are UVC compliant, this includes all c models: http://www.quickcamteam.net/devices/logitech_uvc_device_list.pdf the above list doesn't include the new models yet, but the c310 is just an update on the c300. In fact I don't think manufacturers are still releasing new models that aren't uvc compliant. What you may find are older models (non-uvc) that are re-branded into some new name for marketing reasons (these are usually low end products without HD support) Best regards, Paulo 2010/8/6 brot (linux-uvc-mailinglist) brot+linux-...@minad.de: Hello everyone!

Re: [Linux-uvc-devel] how to let mic on webcam work?
Hi, 2010/7/7 loody milo...@gmail.com: Dear all: I bought a webcam and video part works fine with universal video driver. my question are: 1. how could I let the mic works too? The mic should work through the usb audio alsa driver: snd_usb_audio What modules or configures I should add in kernel? This should already be available with any recent kernel version 2. If I successfully insmod the driver of mic, is there any user mode utility for me to test it? Try guvcview, you should be able to select from different audio sources including the camera mic, also audacity is a very good choice (audio only).

Andrew Hi,
By default vlc uses libv4l, just like most other software, when this
fails it reverts to direct v4l2 access, (you probably should also
check your libv4l version and update it if needed)
vlc seems to be able to open a MJPG stream after a few failed
attempts, I can't really understand why it fails with the other
software (it returns a I/O error when trying to set the stream
format).
Can you increase the driver verbosity and check for error messages with
dmesg ?

Andrew Hi,
you can increase the driver verbosity by setting the trace parameter:
rmmod uvcvideo
modprobe uvcvideo trace=65535
trace level is given by grouping several flags so you can set it to
something like 0xff and get a huge amount of information on the
logs (just don't forget to reset it after you finish debugging)
after this dmesg should be a lot more verbose.
Some cameras require a quirks value to function properly, but you
really need to check what's going on first.

Re: [Linux-uvc-devel] webcam MANTA MM353 Plako on chip ARK3188
Andrew Hi,
You should now make this change more permanent in the driver configuration,
create a file named uvcvideo.conf in /etc/modprobe.d
add the following line:
options uvcvideo quirks=2
the quirks parameter bypasses some problems originated by faulty or
non fully compliant hardware.
In your case the camera fails when getting the min and max values for
the compression settings during probe,
quirks=2 bypasses this.
Laurent, you should add this camera to the uvc_ids list and hard code
the quirk there.
(This list just keeps getting bigger and bigger)

Paulo

did you need more logs, or now we can close this problem?

Andrew Hi,
you can increase the driver verbosity by setting the trace parameter:
rmmod uvcvideo
modprobe uvcvideo trace=65535
trace level is given by grouping several flags so you can set it to
something like 0xff and get a huge amount of information on the
logs (just don't forget to reset it after you finish debugging)
after this dmesg should be a lot more verbose.
Some cameras require a quirks value to function properly, but you
really need to check what's going on first.

Re: [Linux-uvc-devel] YUYV/YUY2 between USB payload and v4l2.
Natalia Hi, Please check guvcview source code: jpgenc.c; dct.c; huffman.c and also vcodecs.c(compress_frame) for a built in MJPG/JPG encoder. Regards, Paulo 2010/6/16 Natalia Portillo clau...@claunia.com: Hi, Continue with my creation of a UVC webcam inside the QEMU emulator, I've found a behavior that makes me ask myself. Is the payload altered in anyway by the uvcvideo driver or the video4linux api? What I'm currently doing is, opening the host device (also UVC in my test computer), setting format as 320x240 YUYV/YUY2, getting a frame (153600 bytes), sending a payload header to the emulated system (2 bytes only, no timestamp etc), sending the frame in 64 bytes chunks. However in the emulated system I'm getting a whole black frame (and really slow). There seems to be any kind of difference between what a real camera is sending me, and what I'm really getting, so I need one of two solutions: 1.- Getting that YUYV/YUY2 payload without differences, so I can resend it as is. 2.- An easy way to convert it to MJPEG format. While I suppose something can be done with libjpeg, my first priority is to avoid any external dependency, and I'm totally unfamiliar with that library. Any help, guidance, etc, will be greatly thanked.

Re: [Linux-uvc-devel] Stream from multimple cameras
Hi, 2010/5/16 bruno.via...@free.fr: - Adrian Sergiu Darabant aser...@yahoo.co.uk wrote : My need is to stream from both cameras in the same time. (...) I tried to do that and I am succeeding up to query and map buffers but then when doing VIDIOC_STREAMON - the first camera starts and the second one always gets kernel: uvcvideo: Failed to submit URB 0 (-28). which seems to be linked with the usb bandwidth. Hello Adrian, This problem is mentioned in the Motion software FAQ: when streaming from multiple USB cams, each one must be plugged to its own USB controller, not on a hub, including motherboard hubs (typically the pair of connectors on top of each other). (cf http://www.lavrsen.dk/foswiki/bin/view/Motion/FrequentlyAskedQuestions first item) I experienced this problem on an eeepc 701 / linux: while streaming only v...@1fps the two webcams (Vesta pro + SPC900) had to be plugged one on each side of the netbook. But I could plug an external harddrive (recording both streams!) in the same hub as one of the cams! Go figure that... Same thing on a Dell desktop PC with Hercules cams under windows XP. I don't know all the details about the USB transfer protocol but my understanding is that - the driver should request a static bandwidth allocation before starting streaming. Would it be possible to force the streaming at a lower rate - maybe loosing some frames from the camera but still allow multiple camera streaming ? Using distinct controllers is obviously just a workaround, but I have no idea if this bandwidth allocation problem can be dealt with at the driver level, I will leave this to competent people... I think the problem with some cameras is that they request more bandwidth than they actually need, so this causes this type of issue. I've add no problem in streaming 2 QuickCam cameras from the same controller in MJPG, but for other models/vendors it fails with the exactly same settings.

Are they stored in some non-volatile memory in the camera? That would be awesome. If I'm not mistaken USB keeps the power on, even during a reboot, so the camera should maintain the control settings. I'm not sure that's guaranteed by the USB standard. I believe the camera should be reset when the computer is restarted. Whether it will loose its settings might depend on the camera firmware. In that case it may depend on the motherboard configuration. I've tested this on my pc and the camera kept it's settings. I've had plenty of problems with this in the past, if the camera crashes for some reason, a reboot won't solve it and it may also prevent a normal boot. Just last week I notice that my pc took much longer than usual to boot and it was also much slower, after a little investigation I found that usb audio was the cause, the camera had crash and couldn't be initiated. In any case, there's no non-volatile memory to store the controls in any of the consumer webcams I know of. Yes this is true.

Re: [Linux-uvc-devel] Framerate of Quickcam Pro 9000
Alan Hi, Yes, the profiles are very useful. Your program in general is very useful, I hope you make a stable release soon, some distros only ship release versions of programs (like mine for example). The latest stable release is 1.3.1 (adds camera button support), unfortunately some distros take quite some time to pick new releases (maybe my fault, I usually do a new release every month or so). I wish the command line uvcdynctrl also supported loading/saving profiles (just like alsactl store / alsactl restore). You are free to post a patch for it ;-) I'll add it to debian and send it upstream. I'm afraid in the next few weeks I won't have much spare time, otherwise I could do it myself. If you fell you can't do it, just remember me again in a couple of weeks. What happens to the camera settings when the computer is rebooted? Are they stored in some non-volatile memory in the camera? That would be awesome. If I'm not mistaken USB keeps the power on, even during a reboot, so the camera should maintain the control settings. You would have to unplug the camera to loose the settings. This is not always a good think, sometimes the camera may crash, meaning that you must physically unplug it to make it work again.

Re: [Linux-uvc-devel] Framerate of Quickcam Pro 9000
Alan Hi, Can you test with guvcview (http://guvcview.berlios.de)?

I tested the camera using mplayer and motion with different light levels. So I tried to fix it by following the instructions here: http://www.quickcamteam.net/documentation/how-to/how-to-maximize-the-frame-rate Unfortunately its still slow, and I think I messed up something because every time I run uvcdynctrl I get this error: [libwebcam] Unknown V4L2 private control ID encountered: 0x0A046D04 (V4L2_CID_PRIVATE_BASE + 33844484) So I think at some moment I used an invalid parameter, so I thought I could rmmod and modprobe uvcvideo to fix it, but no. Reconnecting the camera doesn't help either. So is this an invalid parameter? If so, where is it stored, in some memory inside the camera? And how do I fix the framerate issue? Thanks!

Re: [Linux-uvc-devel] Multiple camera framerate.
Dennis, Can anyone suggest a way to configure the cameras at a higher framerate without overloading the USB bus? Suppose I can read at 10 fps right now without overloading the USB bus. I'd like to set the framerate to 15, but still just capture around 10. You can grab frames at whatever speed you want, but it's the camera framerate that will make a difference in the usb bandwidth and not the amount of frames you get with your application. Is the 10 fps limit achieved with compressed (MJPG) or uncompressed (YUV) frames ? Using compressed frames should allow for much higher framerates when using multiple cameras. Resolution will also have an impact on the bandwidth. Another alternative is to add another usb controler to you system, (a usb pci card if you are using a standard pc). As an example using MJPG I have no problem in using 3 cameras simultaneous (800x...@20 fps) Best Regards, Paulo ___ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
Re: [Linux-uvc-devel] Multiple camera framerate.
Ian 2010/4/27 Ian Latter ian.lat...@midnightcode.org: You can grab frames at whatever speed you want, but it's the camera framerate that will make a difference in the usb bandwidth and not the amount of frames you get with your application. So, if you don't take a frame from the UVC driver, it will simply continue to refresh an internal buffer with new frames from the camera device? Think of it like this, the necessary bandwidth is requested by the device and it will depend on the compression, resolution and framerate, in fact I think some (buggy) devices will always request the maximum bandwidth causing problems on initialization, for these devices I think uvcvideo uses it's own algorithm to calc the necessary bandwidth. Also the device will always try to dispatch frames at the requested framerate, if you don't grab them they will simply be dropped by the driver.

Franz Hi, 2010/4/6 Franz TRIERWEILER franz.trierweiler.ingeni...@gmail.com: Hello, I am trying to make jpeg/png still encoded picture from a uvcvideo compatible webcam with gstreamer. I do this on a Freescale iMX25 evalboard featuring support for the uvcvideo driver. I configured the gstreamer package and v4l2 / uvc support properly through LTIB. My webcam is officialy supported (0c45:62c0) by the Linux UVC driver. indeed, here is what I get when plugging the device: usb 1-1.5: new full speed USB device using fsl-ehci and address 5 usb 1-1.5: not running at top speed; connect to a high speed hub usb 1-1.5: New USB device found, idVendor=0c45, idProduct=62c0 usb 1-1.5: New USB device strings: Mfr=2, Product=1, SerialNumber=0 usb 1-1.5: Product: USB 2.0 Camera usb 1-1.5: Manufacturer: Sonix Technology Co., Ltd. usb 1-1.5: configuration #1 chosen from 1 choice uvcvideo: Found UVC 1.00 device USB 2.0 Camera (0c45:62c0) input: USB 2.0 Camera as /class/input/input3 Everything looks good here. When i just try to launch the following command, then I get the following error: gst-launch-0.10 v4l2src Setting pipeline to PAUSED ... uvcvideo: Failed to submit URB 0 (-28). Pipeline is live and does not need PREROLL ... ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Error starting . Additional debug info: gstv4l2object.c(1886): gst_v4l2_object_start_streaming (): /GstPipeline:pipelin: system error: No space left on device This looks like a bandwidth issue, I get a similar error if I try to open two or three devices at the same time and the request bandwidth is too much for the usb pipe to handle. Are you using a usb1 or usb2 port? Most of these ARM boards use have usb1 ports, so you can't use the full camera capabilities (resolution/fps). ERROR: pipeline doesn't want to preroll. Setting pipeline to PAUSED ... Setting pipeline to READY ... Setting pipeline to NULL ... Freeing pipeline ... The error seems to come from the device/uvcvideo layer since this error clearly relates to the driver endpoints. My final goal is to submit such a command (with the right jpeg/png encoder): gst-launch-0.10 v4l2src ! pngenc ! filesink location=test.png Were there recent fixes to the uvcdriver (which Freescale did not report)? My driver version is 0.1.0. I read this in the uvc_driver.c file (from /linux/drivers/media/video/uvc) provided with my evalboard BSP. I noticed that what I want to do works fine on Ubuntu 09.04 (the kernel Maybe you are using a usb2 port here ? features the uvcvideo). If I type modinfo /lib/modules/2.6.28-11-generic/kernel/drivers/media/video/uvc/uvcvideo.ko I get the following driver version: Don't believe the reported uvc version, use the kernel version instead, uvc is built-in the kernel since 2.6.27 filename: /lib/modules/2.6.28-11-generic/kernel/drivers/media/video/uvc/uvcvideo.ko version: v0.1.0 license: GPL Thus I guess that Freescale BSP uses the same driver version as Ubuntu 09.04 does.

Hi, 2010/4/6 Franz TRIERWEILER franz.trierweiler.ingeni...@gmail.com: Hi Paulo, First many thanks for your answer. I have doubts about using Usb1 ou Usb2 port... I asked Freescal in order to make sure but according to the IMX datasheet, it is a USB 2.0 port. What annoys me is that I read: usb 1-1: not running at top speed; connect to a high speed hub and I do not know how to understand this. usb 1-1: not running at top speed; connect to a high speed hub usb 1-1: New USB device found, idVendor=0c45, idProduct=62c0 usb 1-1: New USB device strings: Mfr=2, Product=1, SerialNumber=0 usb 1-1: Product: USB 2.0 Camera usb 1-1: Manufacturer: Sonix Technology Co., Ltd. usb 1-1: configuration #1 chosen from 1 choice uvcvideo: Found UVC 1.00 device USB 2.0 Camera (0c45:62c0) input: USB 2.0 Camera as /class/input/input2 That's definitely a usb1.1 connection (full speed) since the camera device is usb2 (high speed) you get that type of message. If it is not a USB 2.0 port, is there a way through gst-launch to reduce the image resolution ? I don't think resolution is the only issue here. Usually uvc devices support two types of video stream, compressed MJPG or/and uncompressed YUYV, when connected to a slower usb port they just drop the uncompressed format and support MJPG only and at lower fps/resolutions. I've actually never tried a YUYV camera only on a usb1 port so I'm not sure how this is handled in that case, but most likely it will drop support for higher resolutions. GStreamer I think defaults to yuv so you should also try setting the input format to MJPG, e.g.: gst-launch v4l2src ! image/jpeg,width=320,framerate=15/1,rate=15 You can use guvcview or luvcview to check out available formats and resolutions for the camera in the ARM platform.

Roger Hi, usb 1-1: new full speed USB device using s3c2410-ohci and address 5 I think this explains why you only have MJPG on the ARM board. YUYV requires a higher bandwidth, so it's only available in usb2. But MJPG should also be available with usb2 and from what I understand you only have YUYV ? If this is true then its a bit strange.

Jeff Hi,
2010/3/30 Jeff Van Epps lord...@lordbah.com:
Thanks. Just what I needed. That gets me back to where I was before.
BTW, I wrote a poor request for help. I omitted these items:
my kernel is 2.6.31-21-generic
the original problem was that using Cheese 2.28.1 and all other
programs I've tried, I got I/O error
before I tried to fix anything, the uvcvideo driver version was 256
I wouldn't trust the driver version much, I'm not sure if this is
updated between kernel releases.

Aborting.
luvcview doesn't support float values, try using guvcview (
http://guvcview.berlios.de ), it should set fps automatically, and you
can change the device parameters from the gui.
Okay, guess I have to step down the resolution.

can you increase the driver verbosity and check dmesg output for
uvcvideo errors/warnings ?
do it like this:
create a file named uvcvideo.conf in /etc/modprobe.d
add the following line:
options uvcvideo trace=255
now run:
sudo rmmod uvcvideo
sudo modprobe uvcvideo
now launch guvcview or luvcview and check dmesg output.
Bah.

Okay, I don't know why this still saves uvcvideo version 256, same as it
did before. Where is that coming from?
Like I said I wouldn't trust the version info much
Most significantly, why the I/O error?
Please check dmesg, some cameras are buggy and may need a workaround
to work properly, others are so buggy that they just wont work at all.
(Wow. menuconfig isn't at all daunting, is it? Yikes. Finally found
FireDTV under Multimedia Support / DVB/ATSC adapters and excluded it.)
Sorry, I should have told you were to find it, I'm glad you figure it out. :-)

Re: [Linux-uvc-devel] uvcvideo broke my vloopback module?
Bart, In your case I would first remove the installed modules: make rminstall I would then check for any extra vloopback module still laying around and remove it. Then proceed with a new installation following the how-to, and install vloopback from source: http://www.lavrsen.dk/twiki/bin/view/Motion/VideoFourLinuxLoopbackDevice Best regards, Paulo 2010/3/5 Bart Koppe b...@a-bort.org: Hi Paulo, I now tried: # for file in `find /lib/modules -name *.ko`; do if [[ -e $file.gz ]]; then echo $file.gz should be removed; fi; done This returns nothing. To be sure I also did: # find / -name *.ko.gz but it also does not return anything.. I anyway tried to unload and then load modules. Basically I used to only load vloopback, now also uvcvideo. Unloading and loading in different order does not solve it to.

Thanks, Bart Some outputs according vloopback (the suggestions I found elsewhere to just reboot don't work): # modprobe vloopback FATAL: Error inserting vloopback (/lib/modules/2.6.26-2-686/kernel/drivers/misc/vloopback.ko): Unknown symbol in module, or unknown parameter (see dmesg) dmesg shows: [ 2216.742102] vloopback: disagrees about version of symbol video_devdata [ 2216.742102] vloopback: Unknown symbol video_devdata [ 2216.742102] vloopback: disagrees about version of symbol video_unregister_device [ 2216.742102] vloopback: Unknown symbol video_unregister_device [ 2216.742205] vloopback: disagrees about version of symbol video_device_alloc [ 2216.742210] vloopback: Unknown symbol video_device_alloc [ 2216.742293] vloopback: disagrees about version of symbol video_register_device [ 2216.742298] vloopback: Unknown symbol video_register_device [ 2216.742370] vloopback: disagrees about version of symbol video_device_release [ 2216.742370] vloopback: Unknown symbol video_device_release # cat /proc/version Linux version 2.6.26-2-686 (Debian 2.6.26-21lenny3) (da...@debian.org) (gcc version 4.1.3 20080704 (prerelease) (Debian 4.1.2-25)) #1 SMP Wed Feb 10 08:59:21 UTC 2010 # cat /proc/modules nvidia 7086148 34 - Live 0xf942f000 (P) agpgart 28808 1 nvidia, Live 0xf8a6d000 tun 8292 1 - Live 0xf8a5 ppdev 6468 0 - Live 0xf8a4d000 lp 8164 0 - Live 0xf8a4a000 ipv6 235396 24 - Live 0xf8c73000 powernow_k8 12036 0 - Live 0xf89fc000 cpufreq_powersave 1856 0 - Live 0xf89e3000 cpufreq_userspace 3172 0 - Live 0xf8945000 cpufreq_conservative 5960 0 - Live 0xf8a0c000 cpufreq_ondemand 6476 2 - Live 0xf89f6000 cpufreq_stats 3776 0 - Live 0xf883 freq_table 4224 3 powernow_k8,cpufreq_ondemand,cpufreq_stats, Live 0xf89f9000 fuse 42908 1 - Live 0xf8a56000 compat_ioctl32 1248 0 - Live 0xf8918000 loop 12748 0 - Live 0xf8a07000 parport_pc 22500 1 - Live 0xf8a0 parport 30988 3 ppdev,lp,parport_pc, Live 0xf89da000 snd_hda_intel 325720 0 - Live 0xf8a9 snd_usb_audio 70272 0 - Live 0xf8a1 snd_usb_lib 13472 1 snd_usb_audio, Live 0xf89d5000 shpchp 25528 0 - Live 0xf89ba000 snd_pcm 62660 2 snd_hda_intel,snd_usb_audio, Live 0xf89e5000 snd_seq_midi 5728 0 - Live 0xf8947000 pci_hotplug 23460 1 shpchp, Live 0xf89a6000 pcspkr 2432 0 - Live 0xf88b6000 snd_seq_midi_event 6432 1 snd_seq_midi, Live 0xf898c000 snd_rawmidi 18496 2 snd_usb_lib,snd_seq_midi, Live 0xf89b4000 snd_hwdep 6212 1 snd_usb_audio, Live 0xf8951000 snd_seq 41456 2 snd_seq_midi,snd_seq_midi_event, Live 0xf89c3000 snd_timer 17800 2 snd_pcm,snd_seq, Live 0xf89ae000 uvcvideo 51692 0 - Live 0xf897e000 snd_seq_device 6380 3 snd_seq_midi,snd_rawmidi,snd_seq, Live 0xf894e000 videodev 34656 1 uvcvideo, Live 0xf899c000 snd 45636 8 snd_hda_intel,snd_usb_audio,snd_pcm,snd_rawmidi,snd_hwdep,snd_seq,snd_timer,snd_seq_device, Live 0xf898f000
