Hi, I have Panasonic NV-GS180 (ID 04da:2318) digital camera with "webcam mode". when uvcvideo driver discovers it, says:
usb 2-9: new full speed USB device using ohci_hcd and address 2 usb 2-9: configuration #1 chosen from 1 choice uvcvideo: Found UVC 1.00 device DVC (04da:2318) usbcore: registered new interface driver uvcvideo USB Video Class driver (v0.1.0) and /dev/video1 appears. But no known v4l framegrabber is able to use it. --------------------------------------------------------------------------------------------------------------- mplayer with v4l2 drivers says: Selected driver: v4l2 name: Video 4 Linux 2 input author: Martin Olschewski <[EMAIL PROTECTED]> comment: first try, more to come ;-) v4l2: ioctl get standard failed: Invalid argument Selected device: DVC Capabilites: video capture streaming supported norms: inputs: 0 = Camera; Current input: 0 Current format: unknown (0x47504a4d) v4l2: ioctl set format failed: Invalid argument v4l2: ioctl set format failed: Invalid argument v4l2: ioctl set format failed: Invalid argument v4l2: ioctl set format failed: Invalid argument v4l2: ioctl set format failed: Invalid argument v4l2: ioctl set format failed: Invalid argument v4l2: ioctl set format failed: Invalid argument v4l2: ioctl set format failed: Invalid argument v4l2: ioctl enum norm failed: Invalid argument Error: Cannot set norm!

As the V4L1 compatibility layer is broken, this may not work. If you encounter any problems, use driver=v4l2 instead. Bugreports on driver=v4l with v4l2 drivers will be ignored. ================================================================= Selected device: DVC Capabilites: capture Device type: 1 Supported sizes: 48x32 => 320x240 Inputs: 1 ioctl get channel failed: Invalid argument ioctl get mbuf failed: Invalid argument Segmentation fault --------------------------------------------------------------------------------------------------------------- mencoder gets: (in dmesg) mencoder[7143] trap divide error rip:51cb31 rsp:7ffff5e02dd0 error:0 mencoder[7181]: segfault at 0000000000000008 rip 0000000000517aa7 rsp 00007ffffb1eb378 error 4 --------------------------------------------------------------------------------------------------------------- xcam gets: v4l1 ioctl VIDIOCGCAP, dir=r- (0x803c7601) v4l2 ioctl VIDIOC_QUERYCAP, dir=r- (0x80685600) v4l2 ioctl VIDIOC_ENUMINPUT, dir=rw (0xc050561a) v4l2 ioctl VIDIOC_ENUMINPUT, dir=rw (0xc050561a) v4l2 ioctl VIDIOC_ENUM_FMT, dir=rw (0xc0405602) v4l2 ioctl VIDIOC_TRY_FMT, dir=rw (0xc0d05640) ppdev0: registered pardevice ppdev0: unregistered pardevice v4l1 ioctl VIDIOCGCAP, dir=r- (0x803c7601) v4l2 ioctl VIDIOC_QUERYCAP, dir=r- (0x80685600) v4l2 ioctl VIDIOC_ENUMINPUT, dir=rw (0xc050561a) v4l2 ioctl VIDIOC_ENUMINPUT, dir=rw (0xc050561a) v4l2 ioctl VIDIOC_ENUM_FMT, dir=rw (0xc0405602) v4l2 ioctl VIDIOC_TRY_FMT, dir=rw (0xc0d05640) v4l1 ioctl VIDIOCGCHAN, dir=rw (0xc0307602) v4l2 ioctl VIDIOC_ENUMINPUT, dir=rw (0xc050561a) v4l2 ioctl VIDIOC_G_STD, dir=r- (0x80085617) uvcvideo: Unsupported ioctl 0x80085617 xcam[10553]: segfault at 0000000000000048 rip 000000000040563b rsp 00007fff1b8c8df0 error 4 [I have honestly no idea what ppdev does here, but these messages appear evey time I launch xcam] --------------------------------------------------------------------------------------------------------------- xawtv shows no image and says: This is xawtv-3.95.dfsg.1, running on Linux/x86_64 (2.6.21) /dev/video1 [v4l2]: no overlay support v4l-conf had some trouble, trying to continue anyway Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct ioctl: VIDIOC_G_STD(std=0x2b83d4c9f14d [PAL_B,PAL_G,PAL_H,PAL_D1,PAL_M,NTSC_M,NTSC_M_JP,?,?,SECAM_B,SECAM_H,SECAM_L,?ATSC_8_VSB,(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null)]): Invalid argument ioctl: VIDIOC_S_STD(std=0x0 []): Invalid argument no way to get: 384x288 32 bit TrueColor (LE: bgr-) --------------------------------------------------------------------------------------------------------------- gqcam shows green image and says: Error reading image... dmesg says: uvcvideo: Unknown ioctl 0x8030560a uvcvideo: Unknown ioctl 0x400e7607 (I've enabled trace-level-64, so there are much more different messages, but these two seem most interesting). --------------------------------------------------------------------------------------------------------------- vlc gives just no image. Moreover, these apps behave slight differently in each run, but the main "idea" is the same - i didn't manage to get image captured even once. I've tried all methods and known applications. I've searched this mailing list. Your website says this chipset is supported (as far as I understand this). So what am I missing?
