Dependencies

This skill requires:

• - Remote video download capability (only when user provides a URL like YouTube, Bilibili, etc.):

• - ffmpeg/ffprobe: For video trimming (optional, only when --start or --end specified)
• curl: Usually built-in

Processing Flow

When the user executes the /faceswap command, please follow these steps:

0. Check Dependencies

• - If user provides a remote video URL, check if yt-dlp is available: INLINECODE9
• For local videos without trimming, no additional tools needed

1. Parse Arguments

• - Parse --video and --face parameters
• If remote URL, need to download to local
• Parse time range --start and --end

2. Download Remote Resources

• - If user provides a remote video URL (YouTube, Bilibili, etc.):

• - For images: use curl to download
• Temp directory: /tmp/verging-faceswap/

3. Get Video Duration

• - Use ffprobe: ffprobe -v error -showentries format=duration -of default=noprintwrappers=1:nokey=1 "video.mp4"

4. Trim Video (if --start or --end specified)

• - If user specifies --start or --end parameters, first trim the video
• Use ffmpeg to trim specified time range:

  ffmpeg -i input.mp4 -ss <start> -to <end> -c copy output.mp4
  

• - Or re-encode for accurate frames:

  ffmpeg -i input.mp4 -ss <start> -to <end> -c:v libx264 -c:a aac output.mp4
  

• - Use trimmed video as the file to upload

5. Check User Credits

• - Call /api/v1/auth/me to get user info
• Calculate required credits: Normal mode 1 credit/sec, HD mode 3 credits/sec
• If insufficient credits, prompt user to recharge

6. Upload Video to R2

• - Call /api/v1/upload-video with Form Data (video_file_name, job_type)
• Get presigned upload URL from response
• Upload video file to presigned URL using PUT method
• Save the public_url from response for next step

7. Upload Face Image to R2

• - Same as step 6, but use the face image file
• Save the INLINECODE16

8. Create Job

• - Call /api/v1/faceswap/create-job with Form Data:

8. Poll Job Status

• - Every 5 seconds call /api/v1/faceswap/jobs?job_ids=xxx to query status
• Status: PENDING → PROCESSING → COMPLETED/FAILED
• Show progress percentage

9. Return Result

• - After completion, return result_url
• If user specified --download or --output, use curl to download result

• If user doesn't provide API Key: Prompt user to get one at https://verging.ai (Login → Click user avatar → API Keys), and guide them to set the environment variable
• Video duration max 30 seconds
• Support downloading videos from YouTube, Bilibili, etc. using yt-dlp
