I also grabbed a SVN snapshot of aMSN, but I found it worked fine for me. Well, fine-ish: I can both send and receive webcam sessions, but it does crash occasionally. I spoke to an aMSN developer, and they tell me it's a driver issue. I've seen no "trigger" for the crash, as in it doesn't happen consistently when I do something. Sometimes I see the ioctl messages before the crash, sometimes not. In the log below we can see two crashes - the second crash occurs at the second "Unsupported marker type" line. ioctl: VIDIOC_S_FMT(type=VIDEO_CAPTURE;fmt.pix.width=320;fmt.pix.height=240;fmt.pix.pixelformat=0x56595559 [YUYV];fmt.pix.field=A NY;fmt.pix.bytesperline=0;fmt.pix.sizeimage=0;fmt.pix.colorspace=unknown;fmt.pix.priv=0): Input/output error ioctl: VIDIOC_S_FMT(type=VIDEO_CAPTURE;fmt.pix.width=320;fmt.pix.height=240;fmt.pix.pixelformat=0x47504a4d [MJPG];fmt.pix.field=A NY;fmt.pix.bytesperline=0;fmt.pix.sizeimage=0;fmt.pix.colorspace=unknown;fmt.pix.priv=0): Input/output error ioctl: VIDIOC_QUERYCTRL(id=9963776;type=unknown;name="";minimum=0;maximum=0;step=0;default_value=0;flags=0): Input/output error Unsupported marker type 0x1b Oops: malloc_video_bufs is 1 (expected 0) [utils/linux/capture/libng/grab-ng.c:malloc_bufs_check:231] Oops: processes is 1 (expected 0) [utils/linux/capture/libng/convert.c:process_check:179] attempt to provide package tls 1.5 failed: package tls 1.50 provided instead Unsupported marker type 0x1b Oops: malloc_video_bufs is 1 (expected 0) [utils/linux/capture/libng/grab-ng.c:malloc_bufs_check:231] Oops: processes is 1 (expected 0) [utils/linux/capture/libng/convert.c:process_check:179] attempt to provide package tls 1.5 failed: package tls 1.50 provided instead -- Alex Pounds (Creature) .~. http://www.alexpounds.com/ /V\ http://www.ethicsgirls.com/ // \\ "Variables won't; Constants aren't" /( )\ ^`~'^ _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
