Actual results: Expected results: Additional info: [fmust@localhost ~]$ rpm -qa "*v4l*" libv4l-1.8.1-1.fc23.x86_64 v4l2ucp-2.0.1-14.fc23.x86_64 v4l-utils-1.8.1-1.fc23.x86_64 [fmust@localhost ~]$ lsmod | grep v4l v4l2_common 16384 1 videobuf2_core videodev 163840 3 uvcvideo,v4l2_common,videobuf2_core [fmust@localhost ~]$ lsusb Bus 001 Device 003: ID 04f2:b012 Chicony Electronics Co., Ltd 1.3 MPixel UVC Webcam Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 03f0:a407 Hewlett-Packard Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
I've installed v4l2ucp but it hasn't any option for "flipdown". The web cam work properly under vista and ubuntu.
Hi, This is likely a problem with the upside-down devices table in v4l-utils. I've just build a new version, with an updated upside-down table, perhaps that fixes things ? Please download v4l-utils-1.10.0-1.fc23.x86_64.rpm and libv4l-1.10.0-1.fc23.x86_64.rpm from here: http://koji.fedoraproject.org/koji/taskinfo?taskID=13114599 And then install them by running the following command in a dir with these 2 files: sudo rpm -Uvh *.rpm Then try running cheese again. If that does not help, please do: cat /sys/class/dmi/id/board_name /sys/class/dmi/id/product_name And copy and paste the output of that command here. Regards, Hans
hi, Done but didn't work cheese displays upside down yet. [fmust@localhost ~]$ cat /sys/class/dmi/id/board_name /sys/class/dmi/id/product_name X71SL X71SL thank you, istaff.
Hmm, Not sure what is going on here (specifically not sure why it does work on Ubuntu), can you try running cheese like this: LIBV4LCONTROL_FLAGS=3 cheese and like this: LIBV4LCONTROL_FLAGS=0 cheese One of those 2 should fix things for you, I expect / hope it is the second one. Regards, Hans
When I run cheese with: LIBV4LCONTROL_FLAGS=3 cheese so good to see the webcam works so fine ;) And when I launche with: LIBV4LCONTROL_FLAGS=0 cheese doesn't work picture upside down :| THe first fix is the right fix. You think I'll always have to type this to have the picture right? Thank you very much for your help Hans.
Hi, (In reply to istaff from comment #5) > When I run cheese with: > LIBV4LCONTROL_FLAGS=3 cheese > so good to see the webcam works so fine ;) Ok, so that is both good and bad news, good in that it works, and bad in that for some reason libv4l is not automatically applying those flags on your system. So now we need to find out why. libv4l has a table of laptops which have their webcams mounted upside down (yes vendors do this) and it has special handling for Asus since Asus does not just do this, they do this a lot! So inside http://git.linuxtv.org/v4l-utils.git/tree/lib/libv4lconvert/control/libv4lcontrol.c we've: static const char *asus_board_name[] = { "...", "X71[A-Z]*", "...", NULL }; Which should match with the X71SL your board has in /sys/class/dmi/id/board_name It also has: static const char *asus_board_vendor[] = { "ASUSTeK Computer Inc.", "ASUSTeK Computer INC.", "ASUS CORPORATION", NULL }; Can you do: cat /sys/class/dmi/id/board_vendor And copy and paste the output here, maybe asus put something weird in your board? Last it has: static const struct v4lcontrol_usb_id asus_camera_id[] = { { 0x04f2, 0xb012 }, { 0x04f2, 0xb034 }, { 0x04f2, 0xb036 }, { 0x04f2, 0xb071 }, ... }; Which matches with your lsusb output, and if all 3 arrays contain any match, then libv4l should do the LIBV4LCONTROL_FLAGS=3 automatically ... > And when I launche with: > LIBV4LCONTROL_FLAGS=0 cheese > doesn't work picture upside down :| Ok, so you've an upside-down mounted webcam, which is quite normal on Asus laptops (for other Vendors we've a different table where all 3 items we check must be an exact match for that exact laptop, for Asus we simply want any entry from all 3 arrays to match and then we will assume the cam is upside down as it is that common on Asus). > The first fix is the right fix. You think I'll always have to type this to > have the picture right? Nope, we need to figure out why the special Asus handling code is not triggering on your laptop. > Thank you very much for your help Hans. You're welcome, I actually wrote the upside-down handling code in libv4l, so I'm quite familiar with the problem :) Regards, Hans
Hi Ok, thanks for the explanation now I understand why I have this problem,(like other asus users with webcam). Here's the return for the command: [fmust@localhost ~]$ cat /sys/class/dmi/id/board_vendor PEGATRON CORPORATION [fmust@localhost ~]$ Thank you for your patience Hans.
Hi, I've found some informations about the webcam, don't know if this could help but... Chicony_CNF7050_CNF6131 Camera USB\VID_04F2&PID_B012&REV_0346&MI_00 USB\VID_04F2&PID_B012&MI_00 Sonix

Now the question becomes how to fix this. I will discuss this with the other v4l-util devs. I'll put you in the Cc of the mails.
Hi, I've just started a scratch-build of v4l-utils for F23 with a patch added which should fix your issue in what I believe is the best way to fix it: http://koji.fedoraproject.org/koji/taskinfo?taskID=13149562 Can you please download v4l-utils-1.10.0-2.fc23.x86_64.rpm and libv4l-1.10.0-2.fc23.x86_64.rpm from there (when it is done bulding) and then install them by running the following command in a dir with these 2 files: sudo rpm -Uvh *.rpm Then try running cheese again (without setting LIBV4LCONTROL_FLAGS), it should now do the right thing automatically. Regards, Hans
Hi I'had problems for the install but now it's done and it works, you're the best!!! Happy to have a normal webcam now, if you come in France one day, you'll be welcomed, billion thanks Hans.Merci mille fois encore, THANK YOU !!!!VERY VERY MUCH!!!!
Sorry I come back just to ask how can I do to mark this bug as resolved? I mark it as closed or...? Thanks Hans...you're genius!
Hi, (In reply to istaff from comment #12) > Sorry I come back just to ask how can I do to mark this bug as resolved? I > mark it as closed or...? Thanks Hans...you're genius! The build which I gave you is not an official build, as I'm waiting to see if upstream is ok with the patch, once that is resolved I'll do an official bugfix release and close the bug. Regards, Hans
