Hi all, Hey I'm trying to do some web cam stuff, and I found this link: http://freshmeat.net/projects/libv4l/releases/333037 I was doing the "rpm -qa | grep v4l" and nothing comes up, I did "ls path_to_centos/RPMS/* | grep v4l " and nothing comes up, I did 'yum provides "*/libv4l*"' and nothing comes up. Is the CentOS library for v4l named something different? Is th...

Hi, folks, Updated CentOS 7 the other day. Updated zoom last night. Ancient (15 yr old) USB camera, Logitech QuickCam Express. If I run LD_PRELOAD=/usr/lib64/libv4l/v4l2convert.so cheese, I get video. Zoom, with or without the LD_PRELOAD - no video. I've tried stracing zoom, and created a file /etc/ld.so.preload, with the contents of /usr/lib64/libv4l/v4l2convert.so, and in strace, I see it loading it, but still no video. Anyone got any clues? Bei...

Hi All, Since I will be working on nouveau pretty much starting today I thought it would be good to write a quick self introduction. I'm an FOSS enthusiast / developer since 1996. I've written (and still maintain) various hwmon drivers, various USB webcam drivers, libv4l and libgphoto camlibs for photoframes which use a custom usb protocol and usb redirection over the network for qemu. And although not the original author I'm now a days a maintainer of libusb, usb-3 bulk streams support in the xhci driver, the uas driver, and libahci_platform. In my spare tim...

When I open any wine session I get the following message in the console: ERROR: ld.so: object '/usr/lib64/libv4l/v4l2convert.so' from /etc/ld.so.preload cannot be preloaded: ignored. Is this significant? The 3-4 apps I have installed seem to work (with a few hiccups during installation) but I have no idea of what this error message implies.

Ok... digging still more into this problem that I'm *still* fighting, using mplayer and a higher debug level, what I *think* the significant message is (this is just one example line): libv4lconvert: Error decompressing JPEG: fill_nbits error: need 5 more bits fps = 15.626953, interval = 0.096001, a_skew = 0.000000, corr_skew = 0.000000 vcnt = 1, acnt = 0 Which seems to indicate that for some reason, on *some* hardware, libv4lconvert is doing something wrong that it did correctly in th...
