it creates /dev/video0 although it isn't usable in vlc mplayer or cheese.

[WhyNotHugo]

I've the same issue on ArchLinux since 4.5.0 hit the stable repos. mpv tv:// shows no video.

[xgnata]

Which patches do you apply to compile it without warnings on 4.5??

[hpe009]

Building driver from this source will work: https://github.com/chatziko/bcwc_pcie

[xgnata]

No it does not work on ubuntu "4.4.0-15-generic".

I still get this warning: /usr/local/src/bcwc_pcie/fthd_v4l2.c:287:28: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types] .queue_setup = fthd_buffer_queue_setup, ^ /usr/local/src/bcwc_pcie/fthd_v4l2.c:287:28: note: (near initialization for ‘vb2_queue_ops.queue_setup’)

and this error if I try to load the module anyway: insmod: ERROR: could not insert module ./bcwc_pcie/facetimehd.ko: Unknown symbol in module and of course this error is related to the incompatible pointer type messing up the vb2 struct facetimehd: Unknown symbol vb2_queue_init (err 0) [ 5339.182036] facetimehd: Unknown symbol vb2_ioctl_streamoff (err 0) [ 5339.182064] facetimehd: Unknown symbol vb2_ioctl_expbuf (err 0) [ 5339.182101] facetimehd: Unknown symbol vb2_ops_wait_finish (err 0) [ 5339.182140] facetimehd: Unknown symbol vb2_ioctl_querybuf (err 0) [ 5339.182193] facetimehd: Unknown symbol vb2_fop_release (err 0) [ 5339.182222] facetimehd: Unknown symbol vb2_ioctl_dqbuf (err 0) [ 5339.182244] facetimehd: Unknown symbol vb2_ioctl_create_bufs (err 0) [ 5339.182287] facetimehd: Unknown symbol vb2_ioctl_qbuf (err 0) [ 5339.182306] facetimehd: Unknown symbol vb2_fop_mmap (err 0) [ 5339.182336] facetimehd: Unknown symbol vb2_fop_read (err 0) [ 5339.182374] facetimehd: Unknown symbol vb2_ops_wait_prepare (err 0) [ 5339.182401] facetimehd: Unknown symbol vb2_ioctl_streamon (err 0) [ 5339.182421] facetimehd: Unknown symbol vb2_fop_poll (err 0) [ 5339.182462] facetimehd: Unknown symbol vb2_ioctl_reqbufs (err 0) [ 5685.306243] facetimehd: Unknown symbol vb2_queue_init (err 0) [ 5685.306277] facetimehd: Unknown symbol vb2_ioctl_streamoff (err 0) [ 5685.306290] facetimehd: Unknown symbol vb2_ioctl_expbuf (err 0) [ 5685.306309] facetimehd: Unknown symbol vb2_ops_wait_finish (err 0) [ 5685.306330] facetimehd: Unknown symbol vb2_ioctl_querybuf (err 0) [ 5685.306363] facetimehd: Unknown symbol vb2_fop_release (err 0) [ 5685.306378] facetimehd: Unknown symbol vb2_ioctl_dqbuf (err 0) [ 5685.306389] facetimehd: Unknown symbol vb2_ioctl_create_bufs (err 0) [ 5685.306414] facetimehd: Unknown symbol vb2_ioctl_qbuf (err 0) [ 5685.306423] facetimehd: Unknown symbol vb2_fop_mmap (err 0) [ 5685.306439] facetimehd: Unknown symbol vb2_fop_read (err 0) [ 5685.306461] facetimehd: Unknown symbol vb2_ops_wait_prepare (err 0) [ 5685.306476] facetimehd: Unknown symbol vb2_ioctl_streamon (err 0) [ 5685.306486] facetimehd: Unknown symbol vb2_fop_poll (err 0) [ 5685.306510] facetimehd: Unknown symbol vb2_ioctl_reqbufs (err 0)

Strangely enough this patch looks ok...I must be missing something quite obvious.

[xgnata]

stupid me...insmod does not resolve module dependencies. My script was loading the dependencies with modprobe and then insmod facetimehd did work with kernel4.3. It looks like the v4l2 modules have been reshuffled. Anyway: modprobe -r bdc_pci modprobe facetimehd does work on kernel 4.5 :)

[yaguphire]

doesn't work with https://github.com/patjak/bcwc_pcie it creates /dev/video0 although doesn't seem to work

pulled the source from here https://github.com/chatziko/bcwc_pcie seems to work confirmed for 4.5 kernel.

[dietervanhoutte]

Using Debian and 4.4.0-1-amd64. Cheese not providing video neither.

Using the camera from another application does work as it should.

[stefansedich]

Just installed Arch, running 4.5 kernel, tried to install but I get no video in Cheese or Skype or even Chrome, I also tried the https://github.com/chatziko/bcwc_pcie repo from source but still get no video (have followed all other issues too), is there anything else I can try?

Have you checked that you have a /dev/video0 and correct permissions to access it?

[stefansedich]

I do indeed have a /dev/video0 and I thought I had the permissions to access it (I added myself to the video group and the owner of it is root:video, although I did try change owner to my user to no avail).

mplayer tv:// might tell you something You can also try qv4l2 which is quite nice for testing video

Oh, stupid me, you already posted that. Haven't had my cup of coffee yet :) v4l2: ioctl request buffers failed: Invalid argument is the problem but don't know why it fails. Did you compile with the correct headers for your kernel? What kernel version are you running?

[stefansedich]

I am running 4.5.0-1-ARCH, I will try look at the proper headers (I am new to this so may have done this wrong).

I appreciate your help!

Looks like I have the right headers too. Any other ideas?

[Jack12816]

I have the exact same problem with linux 4.5.0 and 4.5.1 on Archlinux. I've used these AUR packages:

• https://aur.archlinux.org/packages/bcwc-pcie-firmware/
• https://aur.archlinux.org/packages/bcwc-pcie-git/

With linux 4.4.5 everything is working fine. I have the correct linux-headers in place. Is there something I can try? Or any patches? I would like to help here.

Same here MacBookPro11,4 I'm on 4.6.0-0.rc4.git0.1.fc25.x86_64 can successfully load the module I get a /dev/video0 but no picture when using cheese or mpv tv://

camera activity light on the web camera itself turns green so something is happening though..

I manage to build the driver for Linux 4.5.2 with some around patches https://github.com/engstk/bcwc_pcie/commits/master But as soon as it loads Cheese on Ubuntu 16.04, cam LED goes on and image shows for a second then it crashes with a "There was an error playing video from the webcam" I used guvcview and all works good. Using MacBook Air 6,1 early 2014

[slashrsm]

I experienced the same problem on 4.5.1-1-ARCH. Recompiled from https://github.com/engstk/bcwc_pcie/commits/master and camera started to work again (tested with mplayer tv:// and with Hangouts in Chromium).

[yaguphire]

i can confirm on with slashrsm for macbook pro 13" early 2015.

Just reporting that it works fine for me on 4.5.0. I did obviously need a recompilation to solve my PEBKAC problem of trying to use the 4.4 kernel driver.

Debian Jessie with jessie-backports, uname reports 4.5.0-0.bpo.1-amd64 #1 SMP Debian 4.5.1-1~bpo8+1 (2016-04-20) x86_64 GNU/Linux

The engstk clone works for me too on macbook pro 13" (same as for slashrsm and yaguphire)
