libv4l2: error turning on stream: Cannot send after transport endpoint shutdown


ok here is the funny part

sometime when i run gstreamer-properties at times i can see my cam on /dev/video0 and sometimes on /dev/video1 but xawtv and cheese dont respond

any help on this will be appreciated

Apparently karmic is a bummer. Get onto ubuntu forums.

yea this is ok but every bug has some solution

I don't want to put the same energy into solving it that Ubuntu should be putting, but

Looks like a kernel or video driver problem - probably both are suspect. Overlay, IIRC, is writing video information over the existing image - an example being subtitles

this is definitely a kernel problem

since i upgraded my kernel on ubuntu 9.4 just prior to the release of karmic i am facing this problem ....

oh i have updated my nvidia driver also

Kernel or video driver, which is often a kernel type module. Try updating that

the kernel was updated yesterday but the problem yet remains there

Have you got the latest video driver installed?
The idea here, incidentally, is that we help you SOLVE the problem by directing _your_efforts_, which is what will solve the problem. What have you tried?

uname -a
Linux ankush-laptop 2.6.31-15-generic #50-Ubuntu SMP Tue Nov 10 14:53:52 UTC 2009 x86_64 GNU/Linux


nvidia-185 module is being used

any files to check please do tell me

Have you overlay support now? Have you tried updating the driver from the nvidia site? What does xawtv say now? What is not supporting overlay? What has xawtv docs got to say about the error 'no overlay support'. Have you asked there? Nobody's got a magic wand - it only sometimes seems that way:)

hey are u the same guy who helped me to build the encryption module 3 years ago for vector linux

:-). Probably

Okay, you're dead and gone here. It's not finding those plugins, it actually has no protocol to talk to the webcam in. But you're in a stream of this talking to that and sending it on. So when the first one goes awol, all the others fall over with increasingly outraged error messages. libv412 cannot function.

Find out how to get gstreamer going and keep after the first error messages. When you fix them, you can believe the rest.

This stuff is fairly irrelevant until you get the top right.

hmm at times i am able to get the gstreamer part working

but that is not under my control...as of now the control for gstreamer is with the distro

this problem has started cropping up since v4l got converted to v4l2

do u think i play around with this function and the class from where the function is being derived?
gst_v4l2_object_start_streaming (): /GstPipelineipeline2/GstV4l2Src:v4l2src3:

ok this is what i got for

there is none in /usr/lib64

mine is a 64 bit cpu

could this be a problem?

is there a requirement for gspca module

if yes how do i insert it
