Irritating quirkyness: we have a bunch of videocams. To use, we use gspca. Usually, on an upgrade, I just go into the gspca directory (which appears, from their website, to have not been updated since '07), make clean, make, make install. Having gone up to 5.5, did the same. What's happening now is that it works, delivers the mpgs... but dumps errors in the logs: <snip> kernel:

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

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

Hi, folks. Ever since we brought some of our servers up to 6.x, where the gspca module comes with the kernel, instead of us building it, we've been seeing problems. One system gives very strange loops - someone walks through, then repeat a few times, then the next motion, etc. The current problem is that one camera went out on a different server (it's 6.2, and I'm hoping to bring

Hi all - Since upstream patches the stock 2.6.18 kernel into something that is not 2.6.18 (for the rest of the world) I am having issues trying to compile some packages like v4l (latest is needed for a different project). When compiling packages like v4l that a doing conditionals based on kernel number - but - header files are messing other things up... is there some great trick to getting

It's a feature of the UAPI generally supported by the videobuf2 framework and relied on by Chromium OS to get any kind of reasonable performance when accessing V4L2 buffers

Hello all - I'm out of my element with multimedia, can anyone point me in the right direction? I've a pchdtv-3000 card I am trying to record from. I can successfully record audio/video using streamer or watch television with audio using tvtime, so I know the audio is there. I want to record directly to theora. I am trying to do so using ffmpeg2theora like so: ffmpeg2theora --v4l

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.

configure: libv4l 32-bit development files not found. configure: libgsm 32-bit development files not found, gsm 06.10 codec won't be supported. configure: libmpg123 32-bit development files not found (or too old), mp3 codec won't be supported. configure: libopenal 32-bit development files not found (or too old), OpenAL won't be supported. Some one solved that?

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.

This talk of cameras has reminded me of a problem I've not yet been able to solve. I have a Logitech Communicate STX ( ID 046d:08ad Logitech, Inc. QuickCam Communicate STX ) This seems to work under v4l on CentOS 5.4. If I load xawtv (from rpmforge) then I can view the image from the camera. But what I'd like to be able to do is have the image appear on a web page (maybe streaming

Hello all... I'm trying to compile wine 1.3.21 on my Linux Mint Debian Edition machine, because I'm tired of the antique version available from the repositories. Unfortunately, ./configure always ends with a bunch of WARNINGs and I'm not sure what to do about them. Here's the list it gives me: Code: configure: libxcursor development files not found, the Xcursor extension won't
