Guide playback fixture

guide-demo.mpegts is an original, synthetic 20-second H.264 video slate at 1280×720 / 25 fps, with no audio or third-party footage. Feature-guide captures serve it through a local HLS manifest, decode it with the real HTML5 player, and pause the decoded frame for repeatability. No player state or statistics are fabricated. Subtitle menus use the app's normal file-selection flow.

To regenerate on macOS with FFmpeg (Helvetica is a system font):

ffmpeg -f lavfi -i 'gradients=s=1280x720:r=25:c0=0x14243e:c1=0x507f9f:n=2:d=20:speed=0.01:seed=24' \
  -vf "drawtext=fontfile=/System/Library/Fonts/Helvetica.ttc:text='IPTVnator':fontcolor=white:fontsize=52:x=(w-text_w)/2:y=(h-text_h)/2-30,drawtext=fontfile=/System/Library/Fonts/Helvetica.ttc:text='DEMO STREAM':fontcolor=white@0.6:fontsize=20:x=(w-text_w)/2:y=(h-text_h)/2+35" \
  -c:v libx264 -preset fast -crf 28 -pix_fmt yuv420p -g 50 -an \
  -f mpegts tools/release/fixtures/guide-demo.mpegts

Capture the six feature-guide screens with:

pnpm nx run electron-backend:build-e2e
pnpm release:screenshots --group feature-guides --theme dark
