EDIT (10 April 25): I've reworked this post to reflect my latest recommendations for creating a cc4c LXC container in Proxmox. This now uses a Debian 12 template and incorporates the @dravenst cc4c repo. This repo features better error handling, more descriptive console output, command line switches for configurable elements, and some specific support for Sling. I've also added suggested changes to ~/.bashrc to run cc4c on login in an additional post.
I've tried, as have others, to get the Docker version of Chrome-Capture-for-Channels working better. Although, a few have reported acceptable results, most have not. Being able to containerize it, has appeal though -- so, I thought I'd take a shot at installing cc4c directly in a Proxmox LXC container.
It appears to work well, so I thought I'd document the steps for creating a cc4c LXC here:
Stepping through the usual series of windows for creating a new LXC, here are the values I used:
Debian 12 (Bookworm) is the choice here:
8GB should be adequate for disk space, though 16GB is nice if you have the space available:
Cores are important here, with 6 being a nice generous number if you have the vCPUs (which are OK to over allocate). 4 would probably be fine too -- below that I wouldn't recommend:
4096 is generous, 2048 should be fine too. Keep in mind you're running Chrome:
vmbr1 is my 10GbE bridge, so I'm using that. No firewall, and DHCP on IPv4, but use whatever is typical for you:
I'm passing through my iGPU (which can be shared with other LXCs), using the Proxmox 8 method:
And then, here's what needs to be done from the new LXC's Console. These steps are essentially duplicating what's done in the cc4c Dockerfile:
# Add the non-free and non-free-firmware repos to sources.list
sed -i 's/contrib$/contrib non-free non-free-firmware/' /etc/apt/sources.list
# Add va drivers
apt update
apt install intel-media-va-driver-non-free vainfo libva-drm2 libva-x11-2 mesa-va-drivers
# Upgrade the container's OS
apt upgrade
# Install some basic system packages
apt install curl gnupg git
# Add the Node 18 repo via script and install nodejs
curl -fsSL https://deb.nodesource.com/setup_18.x | bash -
apt install nodejs
# Install needed system libraries and utilities

# Add the Chrome signing key and install Chrome
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
echo "deb [arch=amd64] https://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list
apt update
apt install google-chrome-stable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst fonts-freefont-ttf libxss1 --no-install-recommends
# Clone the cc4c repo and install it
cd /opt
git clone https://github.com/dravenst/chrome-capture-for-channels
cd chrome-capture-for-channels
npm install # There will be some warnings here about vulnerabilities that can be safely ignored
# Add required environment variables needed by cc4c and Chrome
echo -e "DISPLAY=:99\nCHROME_BIN=/usr/bin/google-chrome\nDOCKER=true\nLIBGL_ALWAYS_INDIRECT=1\nLIBVA_DRIVER_NAME=iHD" | tee /etc/environment > /dev/null
# Exit followed by a fresh login to pick up the new env vars
exit
At this point you'll be logged out of the LXC's Console, so log back in, and switch to the /opt/chrome-capture-for-channels directory:
cd /opt/chrome-capture-for-channels
The last step will run Xvbf, a VNC server and cc4c itself:
Xvfb :99 -screen 0 1920x1080x16 & x11vnc -quiet -nopw -display :99 -forever & node main.js
cc4c is now running in the foreground, with the other two running in the background, and you should see something like this on your Console:
[1] 16268
[2] 16269
Xlib: extension "DPMS" missing on display ":99".
The VNC desktop is: cc4c2:0
PORT=5900
[2025/02/08 09:09:32.750] Chrome Capture server listening on port 5589
If you kill the foreground cc4c process for any reason. Be sure to kill the two background processes as well. Their PIDs are shown as [1] and [2] at this stage, or you can get them with a ps -ef command.
When you setup your CDVR Custom Channels Source, be sure to include chrome://gpu as a channel so you can check Chrome's stats regarding GPU use:
#EXTM3U
#EXTINF:-1 channel-id="weatherscan",Weatherscan
chrome://cc4c:5589/stream?url=https://v2.weatherscan.net/
#EXTINF:-1 channel-id="chrome.gpu",Chrome GPU
chrome://cc4c:5589/stream?url=chrome://gpu
Use the cc4c hostname in the above M3U if it resolves on your LAN, or substitute the IP address of the LXC container.
Use a VNC client to connect to the container, when a cc4c stream is active, if you need to login to a streaming service, or to go fullscreen. Logins and fullscreen player settings should be maintained by Chrome just like when you're using Chrome locally.
I'll add a script that'll autorun at container start, once I put this into production, and I'll update this step-by-step accordingly.
