Specialized: Video Streaming Support

[sanchxt]

Description

Progressive download enabling video playback before transfer completes.

Requirements

• CLI: yoop share video.mp4 --stream
• Playback starts after 5-10% downloaded
• Supported formats: MP4, MKV, AVI, MOV, WebM
• Chunked transfer with prioritized header chunks
• Options: Save file or stream-only mode
• Pause/resume playback support

Technical Details

• Transfer: Send header/moov atom first for MP4
• Receiver: Write chunks to temp file, expose via HTTP range server
• Player: System default or web-based (video.js)
• Protocol: STREAM_MODE flag in transfer metadata

Streaming Flow

1. Analyze file (detect format, extract header)
2. Send header chunks first (priority queue)
3. Send remaining chunks sequentially
4. Receiver creates endpoint: http://localhost:9000/stream.mp4
5. User opens in player while transfer continues

Limitations

• Best with MP4/WebM (header at beginning)
• MKV may require seeking
• Network interruption pauses playback
