Processing Flow

处理流程

When the user executes the /video-enhancement command, please follow these steps:
当用户执行/video-enhancement命令时,请遵循以下步骤:

0. Check Dependencies

0. 检查依赖项

  • If user provides a remote video URL, check if
    yt-dlp
    is available:
    which yt-dlp
  • For local videos without trimming, no additional tools needed
  • 如果用户提供远程视频URL,检查是否已安装yt-dlp:
    which yt-dlp
  • 对于无需裁剪的本地视频,无需额外工具

1. Parse Arguments

1. 解析参数

  • Parse --video parameter
  • If remote URL, need to download to local
  • Parse --scale (default 2x)
  • Parse time range --start and --end
  • 解析--video参数
  • 如果是远程URL,需要下载到本地
  • 解析--scale(默认2倍)
  • 解析时间范围参数--start和--end

2. Download Remote Resources

2. 下载远程资源

  • If user provides a remote video URL (YouTube, Bilibili, etc.):
    • Try
      yt-dlp "URL" -o /tmp/verging-video-enhancement/video.mp4
    • If yt-dlp is not available, suggest installing the yt-dlp skill:
      npx skills add lwmxiaobei/yt-dlp-skill --skill yt-dlp
    • If installation is not possible, ask the user to download the video locally first
  • Temp directory: /tmp/verging-video-enhancement/
  • 如果用户提供远程视频URL(如YouTube、Bilibili等):
    • 尝试执行
      yt-dlp "URL" -o /tmp/verging-video-enhancement/video.mp4
    • 如果未安装yt-dlp,建议用户安装yt-dlp技能:
      npx skills add lwmxiaobei/yt-dlp-skill --skill yt-dlp
    • 如果无法安装,请用户先将视频下载到本地
  • 临时目录:/tmp/verging-video-enhancement/

3. Get Video Duration

3. 获取视频时长

  • Use ffprobe: ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 "video.mp4"
  • 使用ffprobe:ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 "video.mp4"

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

4. 裁剪视频(如果指定了--start或--end)

  • 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
  • 如果用户指定了--start或--end参数,先裁剪视频
  • 使用ffmpeg裁剪指定时间范围:
    ffmpeg -i input.mp4 -ss <起始时间> -to <结束时间> -c copy output.mp4
  • 或重新编码以获得精确帧:
    ffmpeg -i input.mp4 -ss <起始时间> -to <结束时间> -c:v libx264 -c:a aac output.mp4
  • 使用裁剪后的视频作为待上传文件

5. Check User Credits

5. 检查用户可用点数

  • Call /api/v1/auth/me to get user info
