[v4lsrc] not working with usb camera
Last modified: 2009-08-15 18:40:50 UTC
Hello, I'm trying to connect to a usb camera using gstreamer with the v4lsrc. I have the pwc and pwcx modules running and I have verified video4linux is working with xawtv. My program worked correctly with gstreamer 0.6. However, when running with gstreamer 0.8 I am getting the error message: (process:22384): GStreamer-CRITICAL **: file gstelement.c: line 2027 (gst_element_link_many): assertion `element_1 != NULL && element_2 != NULL' failed /dev/video0 [v4l]: no overlay support ** (process:22384): WARNING **: v4l-conf returned 1. It may be worth noting before showing video, xawtv reports: > This is xawtv-3.94, running on Linux/i686 (2.6.8) /dev/video0 [v4l]: no overlay support v4l-conf had some trouble, trying to continue anyway Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct config: invalid value for input: Television valid choices for "input": "Webcam" ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=7): Invalid argument
That error means nothing, it's just a warning (and was removed recently anyway), but it's not fatal. What are you trying to do and what happens?
