I agree with you that we should return DEVNAME, but let me ask luka before revevrting the commit. Thanks for the bug! SVN commit 1210116 by lukas: return the physical device as the handle, fixes: BUG: 261475 M +1 -1 udevvideo.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1210116 |
Version: unspecified (using KDE 4.5.90) OS: Linux after an upgrade to 4.6RC1 (mandriva Cooker, 64 bit), Kopete doesn't show anymore any video device in the configuration box. I have an integrated webcam on my laptop, seen on the usb bus (a Syntek). After checking code, for solid backends udev and hal, I think that udev's solid/backends/udev/udevvideo.cpp' last change is the culprit. It was changed to not used DEVNAME udev property, but m_device->devicePath() which is something "virtual" - i.e. no actual device path (like in /dev/...) I think that should be reverted back to using DEVNAME property. Output from udevadm related to the video device: P: /devices/virtual/video4linux/video0 N: video0 S: char/81:0 E: UDEV_LOG=3 E: DEVPATH=/devices/virtual/video4linux/video0 E: MAJOR=81 E: MINOR=0 E: DEVNAME=/dev/video0 E: SUBSYSTEM=video4linux E: ID_V4L_VERSION=2 E: ID_V4L_PRODUCT=Syntek USB Video Camera E: ID_V4L_CAPABILITIES=:capture: E: DEVLINKS=/dev/char/81:0 E: TAGS=:udev-acl: messages from Kopete, in .xessions-errors - see around "V4L device path": kopete(6596) Kopete::AV::VideoDevicePool::self: Generated new instance. kopete(6596) Kopete::AV::VideoDevicePool::registerDevice: called, UDI is: "/org/kde/solid/udev/sys/devices/virtual/video4linux/video0" kopete(6596) Kopete::AV::VideoDevicePool::registerDevice: vendor: "KDE" , product: "Devices" kopete(6596) Kopete::AV::VideoDevicePool::registerDevice: V4L device path is "/org/kde/solid/udev/sys/devices/virtual/video4linux/video0" kopete(6596) Kopete::AV::VideoDevice::open: called kopete(6596) Kopete::AV::VideoDevice::open: Unable to open file "/org/kde/solid/udev/sys/devices/virtual/video4linux/video0" Err: 2 kopete(6596) Kopete::AV::VideoDevicePool::registerDevice: Device could not be opened. kopete(6596) Kopete::AV::VideoDevice::close: called. kopete(6596) Kopete::AV::VideoDevicePool::open: called with device -1 kopete(6596) Kopete::AV::VideoDevicePool::open: Device not found.
