ShortVideo TV

A lightweight video feed player for Samsung Tizen 3 TVs via TizenBrew. Plays TikTok and Facebook Reels without loading their websites.

What It Does

Tizen 3 TVs run an old WebKit browser that can't handle modern TikTok/Facebook/Instagram pages. Instead of embedding those sites, this app:

1. Loads a curated feed of video URLs from a Cloudflare Worker backend
2. Plays each video using the TV's native <video> player (H.264 MP4 only)
3. Resolves TikTok videos directly from the TV's own network — no server proxy needed for short clips

Remote Controls

| Button | Action | |--------|--------| | ← → ↑ ↓ | Navigate feed | | OK / Enter | Play / Pause | | ◁ Back | Close player, return to feed | | 🔴 Red button | Clear entire feed |

Backend

The companion Cloudflare Worker provides:

• POST /submit — add a TikTok or Facebook Reels URL to a code's feed
• GET /feed?code=XXX — fetch the feed as JSON
• GET /resolve?url=... — resolve a URL to a playable CDN link
• DELETE /feed?code=XXX — clear all items from a feed

A FastAPI server handles yt-dlp resolution for Facebook Reels and proxies CDN URLs when direct playback fails.

Feed JSON Schema

{
  "items": [
    {
      "id": "unique-id",
      "title": "Video title",
      "source": "TikTok | Facebook",
      "sourceUrl": "https://www.tiktok.com/... or https://facebook.com/reel/...",
      "videoUrl": "https://cdn.example.com/video.mp4",
      "thumbnailUrl": "https://cdn.example.com/thumb.jpg",
      "duration": 0
    }
  ]
}

Supported Sources

| Source | Resolution Method | Notes | |--------|-------------------|-------| | TikTok | TV resolves from __UNIVERSAL_DATA HTML page | Uses TV's residential IP — no Cloudflare Worker proxy needed | | Facebook Reels | Server yt-dlp resolves sd/hd H.264 progressive format | Falls back to server proxy if direct CDN fails |

Technical Constraints

• Tizen 3 codec: H.264/AVC only. No AV1, no VP9.
• TikTok CDN: URLs are IP-bound. Cloudflare Worker egress IPs don't match — so the TV resolves TikTok itself.
• Facebook CDN: Server-side yt-dlp selects sd/hd/b (H.264 progressive) for codec compatibility.
• No login: Only public/no-login videos.
