facetimehd not working in Debian Bookworm #285

Closed rgrove-rsu20 closed 1 year ago

rgrove-rsu20 commented 1 year ago

facetimehd doesn't seem to be working in Bookworm. I think this is how I've installed this in the past (using DKMS in Bullseye): apt -y install dkms linux-headers-amd64 git kmod libssl-dev checkinstall wget https://github.com/patjak/facetimehd/archive/refs/tags/0.5.18.tar.gz tar xf 0.5.18.tar.gz -C /usr/src/ dkms add -m facetimehd -v 0.5.18 dkms build -m facetimehd -v 0.5.18 dkms install -m facetimehd -v 0.5.18 echo "facetimehd" >> /etc/modules

You also need the firmware. See: https://github.com/patjak/facetimehd/wiki/Get-Started#firmware-extraction

rgrove-rsu20 commented 1 year ago

Ok, I was running: https://raw.githubusercontent.com/patjak/facetimehd-firmware/master/facetimehd-firmware-install.sh

However, after running: git clone https://github.com/patjak/facetimehd-firmware.git cd facetimehd-firmware make make install

It still doesn't work for me.

The firmware is now loading. The sensor files are not (errors at the bottom) but they are not required. Are you still not getting a /dev/video0 device?

rgrove-rsu20 commented 1 year ago

yes, a /dev/video0 device is created, however nothing seems to be able to use it. The launch of Cheese hangs for a bit and comes back with 'There was an error playing video from the webcam'. I have both MacBookAir7,2 and MacBookAir7,1 models and both exhibit the same behavior.

rgrove-rsu20 commented 1 year ago

journalctl contains:

pipewire[3451]: spa.v4l2: '/dev/video0' can't allocate enough buffers (4 < 16) pipewire[3451]: pw.port: 0x556b7b5fa760: negotiate buffers on node: -95 (Operation not supported) pipewire[3451]: pw.port: 0x556b7b5fa760: state ready -> error (can't negotiate buffers on port) pipewire[3451]: pw.link: (43.0 -> 56.0) allocating -> error (can't negotiate buffers on port)

rgrove-rsu20 commented 1 year ago

OK, I was able to get it working in Bookworm. Cheese doesn't seem to like it, but that is OK by me. I'm unsure as to why it was failing for me before. The full process for me was: apt -y install dkms linux-headers-amd64 git kmod libssl-dev checkinstall wget https://github.com/patjak/facetimehd/archive/refs/tags/0.5.18.tar.gz tar xf 0.5.18.tar.gz -C /usr/src/ dkms add -m facetimehd -v 0.5.18 dkms build -m facetimehd -v 0.5.18 dkms install -m facetimehd -v 0.5.18 echo "facetimehd" >> /etc/modules git clone https://github.com/patjak/facetimehd-firmware.git cd ./facetimehd-firmware/ make make install
