Aioz Stream Audio Upload

AIOZ Stream Audio Upload

Upload audio to AIOZ Stream API quickly with API key authentication. The full upload flow requires 3 API calls: Create → Upload Part → Complete.

When to use this skill

• User wants to upload or create an audio on AIOZ Stream
• User mentions "upload audio", "create audio", "aioz stream audio"
• User wants to get an HLS streaming link for their audio

Authentication

This skill uses API key authentication. The user must provide:

• stream-public-key: their AIOZ Stream public key
• stream-secret-key: their AIOZ Stream secret key

Ask the user for these keys if not provided. They will be sent as HTTP headers on ALL API calls.

Usage Options

When the user wants to upload audio, ask them to choose:

Option 1: Default Upload (Quick)

Creates an audio object with minimal config — just a title. Then uploads the file.

Example user prompt:

"Upload audio file /path/to/audio.mp3 with title My Podcast"

Option 2: Custom Upload (Advanced)

Creates an audio object with full encoding configuration including quality presets, bitrate, sample rate, tags, metadata, etc. Then uploads the file.

Example user prompt:

"Upload audio with custom config: title My Podcast, highest quality HLS, 320kbps, 48000Hz, tags podcast,tech"

Full Upload Flow (3 Steps)

Step 1: Create Audio Object

Default:

curl -s -X POST 'https://api-w3stream.attoaioz.cyou/api/videos/create' \
  -H 'stream-public-key: PUBLIC_KEY' \
  -H 'stream-secret-key: SECRET_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
    "title": "AUDIO_TITLE",
    "type": "audio"
  }'

Custom (with encoding config):

curl -s -X POST 'https://api-w3stream.attoaioz.cyou/api/videos/create' \
  -H 'stream-public-key: PUBLIC_KEY' \
  -H 'stream-secret-key: SECRET_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
    "title": "AUDIO_TITLE",
    "type": "audio",
    "description": "DESCRIPTION",
    "is_public": true,
    "tags": ["tag1", "tag2"],
    "metadata": [
      {"key": "KEY", "value": "VALUE"}
    ],
    "qualities": [
      {
        "resolution": "highest",
        "type": "hls",
        "container_type": "mpegts",
        "audio_config": {
          "codec": "aac",
          "bitrate": 320000,
          "channels": "2",
          "sample_rate": 48000,
          "language": "en",
          "index": 0
        }
      },
      {
        "resolution": "standard",
        "type": "hls",
        "container_type": "mpegts",
        "audio_config": {
          "codec": "aac",
          "bitrate": 128000,
          "channels": "2",
          "sample_rate": 44100,
          "language": "en",
          "index": 0
        }
      }
    ]
  }'

Response: Extract data.id — this is the AUDIO_ID used in the next steps.

Step 2: Upload File Part

Upload the actual audio file binary to the created audio object.

First, get the file size and compute the MD5 hash:

# Get file size (cross-platform compatible)
FILE_SIZE=$(stat -f%z /path/to/audio.mp3 2>/dev/null || stat -c%s /path/to/audio.mp3)
END_POS=$((FILE_SIZE - 1))

# Compute MD5 hash
HASH=$(md5sum /path/to/audio.mp3 | awk '{print $1}')

Then upload via multipart form-data with the Content-Range header:

curl -s -X POST "https://api-w3stream.attoaioz.cyou/api/videos/AUDIO_ID/part" \
  -H 'stream-public-key: PUBLIC_KEY' \
  -H 'stream-secret-key: SECRET_KEY' \
  -H "Content-Range: bytes 0-$END_POS/$FILE_SIZE" \
  -F "file=@/path/to/audio.mp3" \
  -F "index=0" \
  -F "hash=$HASH"

Important: The Content-Range header is required for the upload to succeed. Format: bytes {start}-{end}/{total_size} where:

• For single-part uploads: start=0, end=file_size-1, total_size=file_size
• For multi-part uploads: adjust start/end positions for each chunk

Form-data fields:

• file: the audio file binary (use @/path/to/file)
• index: 0 (for single-part upload, increment for multi-part)
• hash: MD5 hash of the file part

Step 3: Complete Upload

After the file part is uploaded, call the complete endpoint to finalize:

curl -s -X GET "https://api-w3stream.attoaioz.cyou/api/videos/AUDIO_ID/complete" \
  -H 'accept: application/json' \
  -H 'stream-public-key: PUBLIC_KEY' \
  -H 'stream-secret-key: SECRET_KEY'

This triggers transcoding. The upload is now considered successful.

After Upload — Get Audio Link

After completing the upload, fetch the audio detail to get the streaming URL:

curl -s 'https://api-w3stream.attoaioz.cyou/api/videos/AUDIO_ID' \
  -H 'stream-public-key: PUBLIC_KEY' \
  -H 'stream-secret-key: SECRET_KEY'

Parse the response to find the HLS URL from the assets or hls field and return it to the user.

Important: Audio outputs do NOT have an mp4_url field. Only HLS/DASH streaming links are available.

Custom Upload Config Reference

Quality Presets (resolution field):

• standard — Standard quality
• good — Good quality
• highest — Highest quality
• lossless — Lossless quality

Streaming Formats (type field):

• hls — HTTP Live Streaming (container: mpegts or mp4)
• dash — Dynamic Adaptive Streaming (container: fmp4)

Audio Config:

• codec: aac (only supported codec)
• bitrate: integer in bits/sec (e.g., 128000, 256000, 320000)
• channels: "2" (stereo)
• sample_rate: 8000, 11025, 16000, 22050, 32000, 44100, 48000, 88200, 96000
• language: BCP 47 code (e.g., en, vi)
• index: 0

Recommended bitrates:

• Podcast/Voice: 64000 - 128000 bps
• Music standard: 128000 - 192000 bps
• Music high quality: 192000 - 256000 bps
• Music highest: 256000 - 320000 bps

Recommended sample rates:

• Voice: 22050 or 32000
• Music: 44100 or 48000

Response Handling

1. Parse the JSON response from the create call → extract data.id
2. Compute MD5 hash of the audio file
3. Upload the file part with the hash
4. Call complete endpoint
5. Fetch audio detail to get streaming URL
6. Return the audio link to the user
7. If the audio is still transcoding (status: transcoding), inform the user and suggest checking back later

Error Handling

• 401: Invalid API keys — ask user to verify their public and secret keys
• 400: Bad request — check the request body format
• 500: Server error — suggest retrying

Example Interaction Flow

1. User: "Upload my audio to AIOZ Stream"
2. Ask for API keys (public + secret) if not known
3. Ask for the audio file path
4. Ask: "Default upload (quick) or custom config?"
   • If default: ask for title only
   • If custom: ask for title, quality preset, bitrate, sample rate, tags, etc.
5. Step 1: Create audio object → get AUDIO_ID
6. Step 2: Compute file hash, upload file part
7. Step 3: Call complete endpoint
8. Fetch audio detail → return streaming URL to user
