THIS PACKAGE DOESN'T CURRENTLY WORK - NEEDS TO BE UPDATED FOR UPSTREAM CHANGES


GENERAL USAGE INFORMATION:

  • This package installs the bodypix and fakecam binaries.
  • akvcam support is untested.
  • For support for using bodypix as a systemd service, and using system dependencies, use this package instead of this one.

USING GPU ACCELERATION (NVIDIA ONLY):

Tensorflow requires an older version of CUDA, 10.0, and, by extension (due to package requirements), cuDNN.

Hi everyone! Sorry for the wait, I'm looking into the changes now. It looks like upstream removed support for bodypix, and moved to a different library - I'm gonna see if there is still a benefit to using the bodypix version with GPU, as the new library doesn't seem to have GPU acceleration.

If there is reason to use both versions, then I split off this package into one that uses latest master, and another which supports the "legacy" bodypix version.


For anyone else having issues with bodypix dying with error:

Will fix if this issue is still present.

v4l2loopback should be optional, akvcam is a complete v4l2loopback fork and replacement.

Will fix after the first issue is addressed.

This needs python-pip to build.

Ditto.

but how are we meant to use the /opt dependencies instead?

The way it's meant to work is that I made a small Python launcher script that should prioritize those dependencies. I'll investigate this when I can.


Thanks for the feedback all!

This needs python-pip to build. I also had to install the missing python dependencies, but how are we meant to use the /opt dependencies instead? I also needed linux-headers so that the v4l2loopback DKMS module was installed. I could run bodypix fine, but fakecam still failed with the following.

[ERROR:0] global /build/opencv/src/opencv-4.5.2/modules/videoio/src/cap.cpp (160) open VIDEOIO(CV_IMAGES): raised OpenCV exception:

OpenCV(4.5.2) /build/opencv/src/opencv-4.5.2/modules/videoio/src/cap_images.cpp:253: error: (-5:Bad argument) CAP_IMAGES: can't find starting number (in the name of file): ./.decrypt/chromium/Default/Extensions/cjpalhdlnbpafiamejdnhcphjbkeiagm/1.35.2_0/background.html in function 'icvExtractPattern'

I'm not even sure why it's looking in that directory!

The issue is being discussed on GitHub, along with a temporary quick fix.

Oh! Yes, I had that at one point too. You will be needing to install the gcc7 AUR package. That's cool that you were able to feed the package URL directly to Pacman like that; I updated the instructions with both of those things.

Advice on the "cuda downgrade"? Getting this:

This is intentional. Rather than depending on the Arch packages for these Python libraries and potentially dealing with API breakage down the road, this package bundles the exact library versions in /opt/. If you're not a fan of this, you can use the other package mentioned in the first comment.

Kortekaasy commented on 2021-02-19 11:49 (UTC)

It seems like several python dependencies are missing, such as aio-http, cv2, pyfakewebcam, and requests_unixsocket. Could these be added as dependencies to the package?

I've been meaning to make this package for some time, and started doing so last month - at which point there was no package like this. I finished this package today, and checked again, and sure enough, somebody else has made a package, and submitted it just yesterday! (https://aur.archlinux.org/packages/fake-background-bodypix-git/)

However, there are some key differences between this package and that one:

  • This package bundles all of the Node.js and npm dependencies in /opt/ (along with the program itself). I did this in fear of the Python (and Node) packages in the Arch repos being updated to where they become incompatible with this tool.
  • The other package bundles a nice systemd service.
  • This package includes both bodypix and fakecam in one, whereas the other package splits them into different packages.
