Hi folks, Trying to get a usb webcam based on SN9C20x driver working on Ubuntu. Loading the module, everything looks good (log output trimmed for easy reading): kernel: usb 7-3: new high speed USB device using ehci_hcd and address 4 kernel: usb 7-3: configuration #1 chosen from 1 choice kernel: sn9c20x: SN9C20X USB 2.0 Webcam - 0C45:628F plugged-in. kernel: sn9c20x: Detected OV9650 Sensor. kernel: sn9c20x: Webcam device 0C45:628F is now controlling video device /dev/video0 kernel: input: SN9C20X Webcam as /class/input/input10 kernel: sn9c20x: No ack from I2C slave 0x30 for write to address 0x17 kernel: sn9c20x: Using yuv420 output format However, I've tried several different apps (cheese, Xsane, gstreamer, etc) but cannot see any video output. I confess to being completely ignorant on issues video, etc. :) If I type 'cat /dev/video0 >j.dump', the green LED on camera comes on, and j.dump is filled with binary data. However, gst-launch shows this: # gst-launch-0.10 v4l2src ! ffmpegcolorspace ! ximagesink Setting pipeline to PAUSED ... ERROR: Pipeline doesn't want to pause. WARNING: from element /pipeline0/v4l2src0: Failed to get current input on device '/dev/video0'. May be it is a radio device Additional debug info: v4l2_calls.c(756): gst_v4l2_get_input (): /pipeline0/v4l2src0: system error: Invalid argument ERROR: from element /pipeline0/v4l2src0: Could not negotiate format Additional debug info: gstbasesrc.c(2387): gst_base_src_start (): /pipeline0/v4l2src0: Check your filtered caps, if any Setting pipeline to NULL ... FREEING pipeline ... I'm running Ubuntu Jaunty kernel (2.6.28) with Hardy userland. Any input/pointers would be most appreciated! And if there is a better list to post such a question, I'd appreciate it. I posted on microdia@xxxxxxxxxxxxxxxx, but that list hasn't had a single message in more than 24 hours!
