python - Youtube-dl Python保存mp4文件

Question

我正在使用 Youtube-DL 库，我注意到当我抓取视频时，一些 .mp4 文件不会被保存，但其他文件会保存。

这是我的代码

     ydl_opts = {
    "download_archive": "./data/en-downloaded.txt",
    "restrictfilenames": True,
    "nooverwrites": True,
    "socket_timeout": 1,
    "youtube_include_dash_manifest": True,
    "writeinfojson": True,
    "writesubtitles": True,
    "format": "bestaudio/best",
    # "allsubtitles": True,
    "subtitlesformat": "ttml",
    "progress_hooks": [my_hook],
    "subtitlelangs": lang,
    "writeautosub": True,
    "keepvideo:": True,
    # "--write-srt": True,
    "postprocessors": [{"key": "FFmpegExtractAudio",  "preferredcodec": "wav", "preferredquality": "192",}],
    "prefer_ffmpeg": True,
    "format": "bestvideo[ext=mp4]+bestaudio",
    "outtmpl": "data/raw_files/%(title)s.%(ext)s",
}

我实际上在哪里告诉 youtube-dl 确保保存 .mp4 文件？

您的 keepvideo 选项中有一个拼写错误，引号内有一个额外的冒号，替换

"keepvideo:": True,

与

"keepvideo": True,
