[Bug 516051] Re: gst-launch cannot connect to gspca webcam
Thank you for taking the time to report this bug and helping to make Ubuntu better. A new version of GStreamer is available on Maverick and we are wondering if this bug is still an issue for you with that version? Could you please test and comment back?

[Bug 516051] Re: gst-launch cannot connect to gspca webcam
Ok, I've set gstreamer-properties video output to X Window System (No Xv) (ximagesink), and the test works, but Cheese still doesn't. In fact it shows just a single still image, rather than video. With `cheese --gst-debug-level=2` I get the following warnings: 0:00:05.245175219 2035 0x957c068 WARN bin gstbin.c:2312:gst_bin_do_latency_func:pipeline failed to query latency 0:00:07.836997826 2035 0x963fb10 WARN basetransform gstbasetransform.c:1047:gst_base_transform_acceptcaps:video_scale transform could not transform video/x-raw-yuv, format=(fourcc)I420, width=(int)160, height=(int)120, framerate=(fraction)30/1, pixel-aspect-ratio=(fraction)1/1 in anything we support 0:00:08.432900585 2035 0x963fb10 WARN basetransform gstbasetransform.c:1047:gst_base_transform_acceptcaps:video_scale transform could not transform video/x-raw-yuv, format=(fourcc)I420, width=(int)160, height=(int)120, framerate=(fraction)30/1, pixel-aspect-ratio=(fraction)1/1 in anything we support 0:00:08.528301133 2035 0x9625e40 WARN basetransform gstbasetransform.c:1047:gst_base_transform_acceptcaps:capsfilter1 transform could not transform video/x-raw-rgb, bpp=(int)32, depth=(int)24, endianness=(int)4321, red_mask=(int)65280, green_mask=(int)16711680, blue_mask=(int)-16777216, width=(int)160, height=(int)120, framerate=(fraction)30/1, pixel-aspect-ratio=(fraction)1/1 in anything we support ...and the same warning appears at different frame sizes.

[Bug 516051] Re: gst-launch cannot connect to gspca webcam
Ok, after looking around some more, I find that `gst-launch v4l2src ! ffmpegcolorspace ! xvimagesink` doesn't work because the video chipset and/or driver doesn't support xvideo. Running `gst-launch v4l2src ! ffmpegcolorspace ! ximagesink` (i.e. using ximagesink instead of xvimagesink) shows the webcam as expected. This suggests to me that it's not a gstreamer problem (as I first thought), but a pipeline setup problem in the applications (Cheese, mousetrap) - where do I look to establish how the pipelines are created? -- gst-launch cannot connect to gspca webcam https://bugs.launchpad.net/bugs/516051 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry for the multiple comments - I'm new to this area of investigation.

[Bug 516051] Re: gst-launch cannot connect to gspca webcam
I guess you've isolated the issue to the Intel driver then? Maybe you're running Compiz and it's interfering with Xv (not unheard of). Try disabling Desktop Effects and see if it helps. Another possible workaround: go into gstreamer-properties and change your video to X11/ximagesink. -- gst-launch cannot connect to gspca webcam https://bugs.launchpad.net/bugs/516051 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 516051] Re: gst-launch cannot connect to gspca webcam
Clarification: Both the Test input plugin (colour bars and noise) and the webcam work in gstreamer-properties. (But not in Cheese or gst- launch.) -- gst-launch cannot connect to gspca webcam https://bugs.launchpad.net/bugs/516051 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yup, gstreamer-properties works as expected, with live video from the webcam appearing. -- gst-launch cannot connect to gspca webcam https://bugs.launchpad.net/bugs/516051 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
