segfault with UVC webcam
Hi everyone: I am trying to use a Samsung branded webcam and it's resulting in a segfault. This happens with both 3.13 and 4.3.6 kernels. Googling around doesn't reveal anything useful.

The requested buffer size is the result of multiplying max_pkt_size * max_packets and the rejected config shows a max_packet_size of 0, maybe ithere;'s a problem with either endianness or int size... ???

Re: cx231xx kernel oops
On Mon, December 12, 2011 6:23 am, Devin Heitmueller wrote: For what it's worth, I did do quite a bit of work on cx231xx, including work for mips and arm platforms. That said, all the work done was on the control interfaces rather than the buffer management (my particular use case didn't have the video coming back over the USB bus). How does your app setup the buffers? Is it doing MMAP? Userptr? It's possible userptr support is broken, as that's something that is much less common. And as Andy suggested, if you can test your app under x86, knowing whether the app works with cx231xx under x86 is useful in knowing if you have a mips issue or something that your app in particular is doing. OK, I just tried this with motion (still on the MIPS platform), a totally different app. It tries to allocate a reasonable amount of memory: [1] mmap information: [1] frames=4 [1] 0 length=153600 [1] 1 length=153600 [1] 2 length=153600 [1] 3 length=153600 [1] buffer index 0 VIDIOC_QBUF: Cannot allocate memory [1] ioctl (VIDIOCGCAP): Invalid argument but the driver still tries to grab 800MB. So it's somewhere between the app and the driver. Also, just to be clear, the USB Live 2 doesn't have any onboard hardware compression. It has comparable requirements related to USB bus utilization as any other USB framegrabber. The only possible advantage you might get is that it does have an onboard scaler, so if you're willing to compromise on quality you can change the capture resolution to a lower value such as 320x240. Also, bear in mind that the cx231xx driver may not be properly tuned to reduce the alternate it uses dependent on resolution. To my knowledge that functionality has not been thoroughly tested (as it's an unpopular use case). OK, thanks. I was hoping this was a hardware framegrabber; the info on the website is so ambiguous as to be nearly useless.

It has comparable requirements related to USB bus utilization as any other USB framegrabber. The only possible advantage you might get is that it does have an onboard scaler, so if you're willing to compromise on quality you can change the capture resolution to a lower value such as 320x240. Also, bear in mind that the cx231xx driver may not be properly tuned to reduce the alternate it uses dependent on resolution.

I was hoping this was a hardware framegrabber; the info on the website is so ambiguous as to be nearly useless. I think you're just confused about the terminology. The term framegrabber inherently means that it's delivering raw video (as opposed to having onboard compression and providing MPEG or some other compressed format). All framegrabbers are hardware framegrabbers. Aha. Thanks for the explanation. You may wish to look at the HVR-1950, which is well supported under Linux and does deliver MPEG video. It's obviously more expensive that the USB Live 2 and it has a tuner which you probably don't need, but it does avoid the issue if you have USB bus constraints. I had looked at the HVR-1950 but the power consumption was prohibitive for my application. :-( --Yan -- Pain is temporary.

Re: cx231xx kernel oops
I'm resurrecting an older thread. I have a Hauppage USB Live2 connected to a MIPS box running openWRT. I tried this earlier on a older hardware running the 3.0.3 kernel.

I'm not sure why a Host Controller would die and (hopefully) clean up properly, but that needs investigation. Looking at the oops probably won't yield useful results in terms of finding cx231xx bugs as it happens after the first host controller has bombed out. You should consider having /boot/System.map and the real klogd installed on your system, so the oops backtrace has meaningful symbol names as opposed to addresses (which are meaningless to anyone without a copy of your built kernel). Regards, Andy At a guess, I'm going to say that it's the hardware. This is an old (2006?) vintage access point with limited CPU horsepower. I'm not sure that any further investigations would change the result. I suspect that the hardware is not capable of USB2 speeds although it claims it can and thus the problem.
