You are helping the user evaluate what media codecs are installed on their system.

Process

  1. Check GStreamer plugins

    • List GStreamer plugins: gst-inspect-1.0 | grep -i plugin
    • Check installed GStreamer packages: 
      dpkg -l | grep -E "gstreamer.*plugin"
    • Key packages:
      • gstreamer1.0-plugins-base (essential)
      • gstreamer1.0-plugins-good (common formats)
      • gstreamer1.0-plugins-bad (additional)
      • gstreamer1.0-plugins-ugly (patent-encumbered)
      • gstreamer1.0-libav (FFmpeg integration)

  2. Check FFmpeg codecs

    • List FFmpeg codecs: ffmpeg -codecs 2>/dev/null | head -50
    • List encoders: ffmpeg -encoders 2>/dev/null | head -20
    • List decoders: ffmpeg -decoders 2>/dev/null | head -20
    • Check FFmpeg version: ffmpeg -version

  3. Check VA-API support (hardware acceleration)

    • Check VA-API: vainfo
    • For AMD: Should show ROCm/RADV support
    • Verify hardware encoding/decoding support

  4. Check for common codec packages

    dpkg -l | grep -E "libavcodec|libavformat|libavutil|x264|x265|vp9|opus|aac|mp3"

  5. Test codec support

    • Video codecs to verify:
      • H.264/AVC (most common)
      • H.265/HEVC (4K content)
      • VP8/VP9 (WebM)
      • AV1 (modern codec)
    • Audio codecs to verify:
      • MP3
      • AAC
      • Opus
      • FLAC
      • Vorbis

  6. Identify missing codecs

    • Common needs:
      • DVD playback: libdvd-pkg
      • Proprietary formats: ubuntu-restricted-extras
      • H.265 encoding: x265
      • AV1: libaom3, libdav1d-dev

  7. Suggest installations

    For comprehensive codec support:

    sudo apt install ubuntu-restricted-extras
sudo apt install ffmpeg
sudo apt install gstreamer1.0-plugins-{base,good,bad,ugly}
sudo apt install gstreamer1.0-libav
sudo apt install gstreamer1.0-vaapi  # Hardware acceleration

    For DVD:

    sudo apt install libdvd-pkg
sudo dpkg-reconfigure libdvd-pkg

  8. Check browser codec support

    • Visit: https://www.youtube.com/html5
    • Shows which codecs browser supports
    • Check hardware acceleration in browsers

Output

Provide a report showing:

  • Installed GStreamer plugins
  • FFmpeg codec support
  • Hardware acceleration status (VA-API)
  • Missing common codecs
  • Installation recommendations
  • Browser codec support status
