Mesa Description

TL;DR

Enabled PulseAudio-based audio support in the headful Chromium image and updated the client UI with a new theme color and improved video unmute experience.

Why we made these changes

To provide audio drivers and socket support for a live view with audio, adapting previous audio support to the new image setup, and to update the client loader theme.

What changed?

Container/Runtime (chromium-headful)

• PulseAudio Integration:
  • Installed rtkit and upower packages in Dockerfile.
  • Configured kernel user to audio, video, and pulse groups.
  • Set XDG_RUNTIME_DIR and PULSE_SERVER environment variables.
  • Added start-pulseaudio.sh script for robust PulseAudio daemon management.
  • Introduced daemon.conf for low-latency WebRTC PulseAudio configuration.
  • Added default.pa for virtual audio sinks/sources and Unix socket access.
  • Included dbus-mpris.conf and dbus-pulseaudio.conf for D-Bus service ownership.
• Permissions and Paths:
  • Adjusted /etc/pulse directory permissions.
  • Updated xorg.conf to allow SocketMode "0666" for dummy_touchscreen input device.
• Wrapper Script Enhancements:
  • Refactored wrapper.sh to explicitly set audio and display environment variables.
  • Improved PulseAudio startup reliability with a 10-second wait loop and explicit shutdown.

Client/UI

• Brand Color Update:
  • Changed brand color to #7B42F6 across browserconfig.xml, index.html, site.webmanifest, and _variables.scss.
• Loader Animation:
  • Added kernel.svg and updated connect.vue to use a spinning kernel.svg image as the loader.
• Video Player Enhancements:
  • Implemented "unmute on first interaction" in video.vue with global event listeners.
  • Added a pulsating red border as a visual muted indicator.
  • Minor control template tweaks in video.vue.
• Connect Component:
  • Retained auto-login hook and switched loader to the new logo spinner in connect.vue.

Performed full review of b51da91...947a021

Analysis

1. Security Permission Issues: Multiple files have overly permissive settings (777/666) including xorg.conf, start-pulseaudio.sh, and Dockerfile configurations for /etc/pulse. These should be replaced with more restrictive 0660/0750 permissions with appropriate group ownership.

2. Contradictory Configuration: PulseAudio has conflicting settings with daemon.conf setting allow-module-loading = yes while start-pulseaudio.sh uses the --disallow-module-loading flag, creating potential maintenance confusion.

3. Environment Variable Redundancy: Environment variables are set in multiple places (Dockerfile, wrapper.sh), which could lead to maintenance challenges if values need to change.

4. Code Redundancy: The video.vue component uses both { once: true } option AND manual cleanup in beforeDestroy, creating unnecessary code.
