Technical Documentation: Media Upload & Playback Module

1. Multi-Format Support

The module supports various media types including video (MP4, MOV), audio (MP3, WAV), and documents (PDF, DOCX). It automatically detects file formats and transcodes them for optimal playback across devices.

2. Streaming Playback

Utilizes HTTP Live Streaming (HLS) and MPEG-DASH protocols for adaptive streaming. These technologies ensure smooth playback by adjusting quality based on network conditions, minimizing buffering issues.

3. Upload & Storage Management

Media files are securely stored with versioning control, allowing users to manage updates without overwriting previous versions. This feature ensures data integrity and easy recovery of past file states.

4. Access Control & Security

Implements authentication (API keys, OAuth), role-based access control for user permissions, and encryption (SSL/TLS) for data protection during transit and at rest. Audit logs track all access attempts for security monitoring.

5. Customizable Player UI

The embedded player offers customization options through settings or APIs. Developers can adjust the UI to match their platform’s design, enhancing user experience without compromising functionality.

6. Transcript & Closed Captions

Supports adding transcripts and captions in formats like .SRT and .VTT. These are synchronized with playback for better accessibility and user engagement.

7. API Integration

Provides RESTful APIs (e.g., GET /media/{id}) enabling programmatic interaction, such as retrieving media details or initiating uploads. This allows developers to integrate the module into custom workflows.

8. Analytics & Reporting

Tracks usage data including views, completion rates, and popular times. This information is gathered through lightweight tracking scripts, providing insights for content optimization.

Category: Classroom

Summary:

The Media Upload & Playback module allows users to upload various types of media (videos, audio, documents) and stream them within a classroom setting. The module is designed to handle both file uploads and playback functionality seamlessly.

Code Samples:

1. FastAPI Endpoint for Media Upload

from fastapi import APIRouter, Depends, HTTPException, status
from fastapi.security import OAuth2PasswordBearer
import os
from pydantic import BaseModel
from typing import Optional

router = APIRouter()
oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token")

class UploadFile(BaseModel):
    title: str
    description: Optional[str] = None
    file: bytes
    media_type: str  # e.g., "video/mp4", "audio/wav", "application/pdf"
    duration: Optional[float] = None  # for video/audio

@router.post("/upload", dependencies=[Depends(oauth2_scheme)])
async def upload_media(
    file_info: UploadFile,
    title: str = Form(...),
    description: Optional[str] = Form(None),
    media_type: str = Form(...),
    duration: Optional[float] = Form(None)
):
    try:
        # Save the file to a designated directory
        filename = f"{title}_{hash(file_info.file.read())}."
        file_path = os.path.join("uploads", filename)
        with open(file_path, "wb") as f:
            f.write(file_info.file.read())

        return {"message": "File uploaded successfully"}
    except Exception as e:
        raise HTTPException(
            status_code=status.HTTP_500_INTERNAL_SERVER_ERROR,
            detail=str(e),
        )

2. React UI for Media Upload

import { useDropzone } from 'react-dropzone'
import { Button } from '@mui/material'

const MediaUpload = () => {
    const onDrop = useCallback((acceptedFiles) => {
        // Handle file upload logic here
        console.log('Accepted files:', acceptedFiles)
    }, [])

    const { getRootProps, getInputProps, isDragActive } = useDropzone({
        onDrop,
        accept: {
            'video/*': ['.mp4', '.avi'],
            'audio/*': ['.wav', '.mp3'],
            'application/pdf': ['.pdf']
        }
    })

    return (
        <div className="upload-container">
            <input {...getInputProps()} />
            <div {...getRootProps()}>
                {isDragActive ? (
                    <p>Drop the files here...</p>
                ) : (
                    <Button variant="outlined" component="span">
                        Choose Files
                    </Button>
                )}
            </div>
        </div>
    )
}

export default MediaUpload

from pydantic import BaseModel
from typing import Optional

class MediaMetadata(BaseModel):
    title: str
    description: Optional[str] = None
    duration: Optional[float] = None  # For video/audio files
    uploaded_by: str
    upload_date: str
    file_size: int
    media_type: str  # e.g., "video", "audio", "document"

class UploadRequest(BaseModel):
    file: bytes
    metadata: MediaMetadata
    file_info: dict  # Additional information about the file (optional)
