bash - Youtube-dl下载脚本调试

Question

弃用更新此帖子的想法很糟糕。此脚本的新位置:
https://gist.github.com/Wogol/66e9936b6d49cc5fecca59eaeca1ca2e

我试图创建一个使用简单的Youtube-dl的.command macOS脚本(也应该在GNU / Linux下工作)。我已经修复，所以它可以下载描述，缩略图，字幕，json，创建文件夹结构，还可以保存视频ID，上传者和上传日期。

主要脚本的问题:

固定(8月13日)我遇到的问题是音频和视频或仅音频的选项。由于某些原因，脚本中只能使用音频。视频和音频的下载脚本不起作用，但是如果我在终端窗口中粘贴相​​同的命令行(“DEBUG输出行”)，它将起作用。挠我的头。
Youtube-dl给了我这个信息:
错误:请求的格式不可用

固定(8月31日)获取视频工作的最大分辨率。找到了强制mp4或最大分辨率的信息，但未将它们组合在一起。

带有信息文件的 问题:
还创建一个带有标题， channel 名称，发行日期，描述的信息文件。我现在正努力从.json和youtube-dl获取视频信息以导出到info.txt文件中。

修复(9月5日) textfile =“” $ folder“info.txt”不起作用。出现此错误:(我要在其中添加youtube-dl文件夹。

    ytdl.command: line 104: ~/Downloads/ytdl/dog_vids/info.txt: No such file or directory

修复(9月5日)找到youtube-dl文件夹并使其与grep一起使用。
像这样:

   youtube-dl --simulate --SHOW_THE_OUTPUT_PATH -o $folder'/%(title)s/%(title)s - (%(id)s) - %(uploader)s - %(upload_date)s.%(ext)s' https://www.youtube.com/watch?v=dQw4w9WgXcQ

(固定)(9月5日)我用grep命令将json文件命名为“* .json”，因为每个目录只有一个，但是我不喜欢这种解决方案。 (可以通过以上几点回答)

固定(9月5日)如何使grep不要抓取“？”现在将它们添加在所有内容的前后。

固定(9月5日)如何从json文件中获取标签信息？标签看起来像这样:

    "tags": ["music", "video", "classic"]

已修复(9月5日)在下载视频的后台运行脚本的信息文件部分的创建吗？

正在尝试使用最新版本
(8月12日)

    textfile=""$folder"info.txt"
    
    echo TITLE >> ~/Downloads/ytdl/dog_vids/info.txt
    youtube-dl -e $url >> ~/Downloads/ytdl/dog_vids/info.txt
    echo \ >> ~/Downloads/ytdl/dog_vids/info.txt
    
    echo CHANNEL >> $textfile
    echo \ >> $textfile
    
    echo CHANNEL URL >> $textfile
    echo \ >> $textfile
    
    echo UPLOAD DATE >> $textfile
    echo \ >> $textfile
    
    echo URL >> $textfile
    echo $url >> $textfile
    echo \ >> $textfile
    
    echo TAGS >> $textfile
    echo \ >> $textfile
    
    echo DESCRIPTION >> $textfile
    youtube-dl --get-description $url >> $textfile

实验 future 版本-从JSON文件中提取信息
这不是工作脚本。通过$ textfile，$ ytdlfolder和$ jsonfile显示我想要的方式。

    url=https://www.youtube.com/watch?v=dQw4w9WgXcQ
    
    textfile=""$folder""$YOUTUBE-DL_PATH"info.txt"
    ytdlfolder="$folder""$YOUTUBE-DL_PATH"
    jsonfile="$folder""$YOUTUBE-DL_JSON-FILE"

    Echo TITLE >> $textfile
    grep -o '"title": *"[^"]*"' $jsonfile | grep -o '"[^"]*"$' >> $textfile
    Echo \ >> $textfile
    
    Echo CHANNEL >> $textfile
    grep -o '"uploader": *"[^"]*"' $jsonfile | grep -o '"[^"]*"$' >> $textfile
    Echo \ >> $textfile
    
    Echo CHANNEL URL >> $textfile
    grep -o '"uploader_url": *"[^"]*"' *.json | grep -o '"[^"]*"$' >> $textfile
    Echo \ >> $textfile
    
    Echo UPLOAD DATE >> $textfile
    grep -o '"upload_date": *"[^"]*"' *.json | grep -o '"[^"]*"$' >> $textfile
    Echo \ >> $textfile
    
    Echo TAGS >> $textfile
    grep -o '"tags": *"[^"]*"' *.json | grep -o '"[^"]*"$' >> $textfile
    Echo \ >> $textfile
    
    echo URL >> $textfile
    echo $url >> $textfile
    echo \ >> $textfile
    
    Echo DESCRIPTION >> $textfile
    youtube-dl --get-description $url >> $textfile

脚本:
8月12日。

将网址移到顶部，因此当用户粘贴网址时，他们会获得视频标题。这样用户就知道他们得到了正确的视频。

添加了最大分辨率1920x1080。 (不工作)

8月13日。

下载音频和视频作品。

8月31日

固定力mp4，最大高度为1080。

9月5日。

最后可以运行的脚本。在此处了解更多信息(或向下滚动):
Youtube-dl download script debug

2020-09-17

文件夹现在可以在其中包含空格。

2020-09-22

选择菜单现在是一列。

次要修复。

现在，所有错误已修复。剩下的问题只是优化。

    # Big thanks to the people at youtube-dl GitHub and Stack Overflow. Without

    # #####
    #
    # Software required:                 youtube-dl, xidel, printf
    #
    # macOS:       1. Install Homebrew:  https://brew.sh
    #              2. Terminal command:  brew install youtube-dl xidel
    #
    # Linux:       Depends on package manager your distribution use.
    #
    # #####
    #
    # Version history:
    # 2020-09-22
    #   - Select menus is now one column.
    #   - Minor fixes.
    #   - Now all the bugs is fixed. Issues left is only optimizations.
    #
    # 2020-09-17
    #   - Folders can now have spaces in them.
    #
    # 2020-09-05
    #   - First working version.
    #
    # #####
    #
    # Issues left:
    #   - In the beginning there is a confirmation that show the title of the
    #     video so user know they got the correct video. It takes youtube-dl a
    #     couple of seconds. To speed up the script it is DISABLED by default.
    #
    #   - Have found out that the script dont need xidel to get json information
    #     but youtube-dl can get it. Dont know how to use youtube-dl --dump-json
    #     to get the same result.
    #
    #   - To get the path to the .txt file script use youtube-dl. This gives the
    #     script a pause for a few seconds. Best would get to get the path some how
    #     without connecting to YouTube again but use the output from youtube-dl
    #     some how. ... or run it in the background when video is downloading.

Answer 1

我已修复，现在可以下载音频和视频。问题出在AV行中。删除了它们，现在工作正常。还针对youtube-dl从手册中更新了影音线。
无法运作:

    av="-f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/bestvideo+bestaudio' --merge-output-format mp4"

加工:

    av="-f bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best --merge-output-format mp4"
