Microservice Overview + +The core of the microservice is a Python Flask application that exposes endpoints to handle video uploads and processing. + +### Key Functionalities: + +* **Video Upload:** Receives a video file associated with a unique `video_id`. +* **Audio Detection:** Uses `ffprobe` to check if the uploaded video contains an audio stream. +* **HLS Transcoding:** Transcodes the video into four different resolutions and bitrates for adaptive streaming: + * 1080p (3000k) + * 720p (1500k) + * 480p (800k) + * 360p (400k) +* **Master Playlist Generation:** Creates a master `.m3u8` playlist that references all the different quality streams. +* **Supabase Integration:** Uploads the generated HLS playlists (`.m3u8` files) and video segments (`.ts` files) to a specified Supabase storage bucket. +* **Cleanup:** Removes the original uploaded file and the processed files from the local server after a successful upload to Supabase. +* **Logging:** Maintains a detailed log file (`ffmpeg_app.log`) to track all operations, commands, and errors. + +## 3. API Endpoints + +### `POST /upload/` + +This is the main endpoint for processing a video. + +* **URL Parameter:** + * `video_id` (string): A unique identifier for the video. This ID is used to create a directory structure in the Supabase bucket. +* **Request Body:** + * `multipart/form-data` with a single file field named `file`. The value should be the video file to be processed. +* **Successful Response (200 OK):** + * **Content-Type:** `application/json` + * **Body:** + ```json + { + "ok": true, + "video_id": "your_video_id", + "has_audio": true, + "message": "video processed successfully!", + "master_playlist": "https:///storage/v1/object/public/blog_videos/your_video_id/master.m3u8" + } + ``` +* **Error Response (4xx/5xx):** + * **Content-Type:** `application/json` + * **Body:** + ```json + { + "error": "A descriptive error message." + } + ``` + +### `GET /` + +A simple endpoint to check if the service is running. + +* **Successful Response (200 OK):** + * **Content-Type:** `application/json` + * **Body:** + ```json + { + "message": "🎬 Welcome to FFmpeg HLS Processor with Full Logging!", + "upload_endpoint": "/upload/", + "example_video": "/videos//master.m3u8" + } + ``` + +## 4.

Video Processing Workflow + +1. The main application sends a `POST` request to the `/upload/` endpoint of the FFmpeg microservice with the raw video file. +2. The microservice saves the file to a temporary `uploads` directory. +3. It checks for the presence of an audio stream using `ffprobe`. +4. It runs a series of `ffmpeg` commands to transcode the video into multiple HLS streams. Each stream (resolution) is placed in its own subdirectory. +5. A `master.m3u8` playlist is created, pointing to the individual stream playlists. +6. The entire directory containing the master playlist and all video segments is uploaded to the Supabase storage bucket under a path corresponding to the `video_id`. +7. After a successful upload, the temporary files and directories on the microservice's local filesystem are deleted. +8. The microservice returns a JSON response containing the public URL to the master playlist on Supabase. + +## Code +```python +import os +import sys +import json +import subprocess +import shutil +import logging +from datetime import datetime +from flask import Flask, request, jsonify, send_from_directory, abort +from dotenv import load_dotenv +from supabase import create_client + +# ------------------------- +# Setup Logging +# ------------------------- +LOG_FILE = "ffmpeg_app.log" +logging.basicConfig( + filename=LOG_FILE, + level=logging.DEBUG, + format="%(asctime)s [%(levelname)s] %(message)s", + datefmt="%Y-%m-%d %H:%M:%S" +) +console_handler = logging.StreamHandler() +console_handler.setLevel(logging.INFO) +console_handler.setFormatter(logging.Formatter("%(asctime)s [%(levelname)s] %(message)s")) +logging.getLogger().addHandler(console_handler) + +# ------------------------- +# Load Environment Variables +# ------------------------- +load_dotenv('/home/ffmpeg/ffmpeg/.env') + +UPLOAD_FOLDER = os.path.join("ffmpeg", "static", "uploads") +OUTPUT_FOLDER = os.path.join("ffmpeg", "static", "videos") +os.makedirs(UPLOAD_FOLDER, exist_ok=True) +os.makedirs(OUTPUT_FOLDER, exist_ok=True) + +SUPABASE_URL = os.getenv('SUPABASE_URL') +SUPABASE_KEY = ( + os.getenv('SUPABASE_SERVICE_ROLE_KEY') or + os.getenv('SUPERBASE_SERVICE_ROLE_KEY') or + os.getenv('SUPABASE_ANON_KEY') or + os.getenv('SUPABASE_ANON_KEY') +) +BLOG_VIDEOS_BUCKET = ( + os.getenv('BLOG_VIDEOS_BUCKET') or + os.getenv('SUPABASE_VIDEOS_BUCKET_NAME') or + 'blog_videos' +) + +if os.getenv('SUPABASE_SERVICE_ROLE_KEY') or os.getenv('SUPERBASE_SERVICE_ROLE_KEY'): + logging.warning("⚠️ Using Supabase service role key.
