Quickstart

Run your first FFmpeg task on FFHub in 3 minutes.

This guide walks you through your first FFmpeg API call: get an API key, submit a transcoding task, and read the result.

1. Get an API Key

Sign up at ffhub.io and create an API key in the dashboard. The key looks like sk_xxxxx — keep it private.

You also get free credits when you sign up, so the steps below cost nothing to try out.

2. Submit a Task

Send any FFmpeg command to POST /v1/tasks. Inputs must be public URLs — local paths get rejected by the cloud worker.

curl -X POST https://api.ffhub.io/v1/tasks \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "command": "ffmpeg -i https://storage.ffhub.io/Sample_Video_File_100MB.mp4 -c:v libx264 -preset fast output.mp4"
  }'

const res = await fetch("https://api.ffhub.io/v1/tasks", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.FFHUB_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    command:
      "ffmpeg -i https://storage.ffhub.io/Sample_Video_File_100MB.mp4 -c:v libx264 -preset fast output.mp4",
  }),
});
const { task_id } = await res.json();

import os, requests

res = requests.post(
    "https://api.ffhub.io/v1/tasks",
    headers={"Authorization": f"Bearer {os.environ['FFHUB_API_KEY']}"},
    json={
        "command": "ffmpeg -i https://storage.ffhub.io/Sample_Video_File_100MB.mp4 -c:v libx264 -preset fast output.mp4",
    },
)
task_id = res.json()["task_id"]

The response gives you a task_id you'll use to poll status:

{
  "task_id": "01abcd…",
  "status": "pending",
  "created_at": "2026-05-10T12:00:00Z"
}

3. Poll Until Done

curl https://api.ffhub.io/v1/tasks/TASK_ID \
  -H "Authorization: Bearer YOUR_API_KEY"

Poll once every 2–5 seconds. When status becomes completed, the response includes a public download URL:

{
  "task_id": "01abcd…",
  "status": "completed",
  "progress": 100,
  "outputs": [
    {
      "filename": "output.mp4",
      "url": "https://storage.ffhub.io/outputs/01abcd…/output.mp4",
      "size": 10485760
    }
  ]
}

Output URLs expire after 24 hours — download what you want to keep.

Uploading Local Files

If your input isn't already a public URL, upload it first to get one. Two steps:

# 1. Ask for a one-time signed PUT URL
SIGNED=$(curl -s -X POST https://api.ffhub.io/v1/uploads/sign \
  -H "Authorization: Bearer $FFHUB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"filename":"input.mp4","size":12345678,"content_type":"video/mp4"}')

# 2. PUT the file directly to R2 — your server never sees the bytes
curl -X PUT "$(echo "$SIGNED" | jq -r '.upload_url')" \
  -H "Content-Type: video/mp4" \
  --data-binary "@./input.mp4"

# The .public_url field is what you pass to `-i` in the task command.
