[linux-uvc-devel] Webcam issues

[Jason S. <jas...@at...>]

Hello,

    I am trying to get a 5Mpixel usb camera from ELP to capture images.  I
am getting corrupted images, only a few rows of good data followed by
nothing when capturing at 5M MJPEG.   My goal is to capture at 5M YUYV
uncompressed.   I can capture images from the camera at lower resolutions
in MJPEG.  Also, I can capture 5M jpgs on my Windows box with this camera.


Tried guvcview, ffmpeg, but both crashed when trying to acquire an image

Capture command that does not crash, but has corrupted images:
>> fswebcam -S 2 -d /dev/video0 -p MJPEG -r 2592x1944 --save pic.jpg

I have also set:
>> modprobe uvcvideo quirks=642 nodrop=1 timeout=10000

I am running on a Beaglebone Black Industrial (Rev C) with latest Debian
image for it:
Linux beaglebone 4.9.45-ti-r57 #1 SMP PREEMPT Fri Aug 25 22:58:38 UTC 2017
armv71 GNU/Linux

Kernel traces attached.

Thanks in advance for any assistance
