VideoDownloader 2024.07.11
VideoDownloader是一個基於yt-dlp的python庫開發的影片下載程式。
yt-dlp 是一款功能豐富的命令列音訊/視訊下載器，支援數千個網站。該專案是基於現已停用的youtube-dlc 的youtube-dl 的一個分支。
yt-dlp基本上支援所有常見的影片網站，它是一個功能十分強大、參數十分豐富的命令列程式。本專案基於yt-dlp的python庫（yt_dlp）進行開發，使用tkinter庫構建了用於視頻下載的GUI應用程序，免去了在命令行輸入冗長的命令的過程，帶給您一個輕鬆的下載體驗。
預設使用Windows環境，我使用pycharm+Anaconda:
python>=3.8
ffmpeg，用於下載後自動合併音頻和視頻，注意是ffmpeg的二進制可執行文件，而不是python庫，記得添加到環境變量，如： D:ffmpegbin
（1）克隆本項目
git clone [email protected]:CQUPTLei/VideoDownloader.git
（2）為專案新建conda虛擬環境，範例：
conda create -n videodownload python=3.12
（3）使用pip安裝yt_dlp函式庫：
conda activate videodownload pip install yt-dlp
Linux下，以Ubuntu24.04為例，使用vim編輯，python venv虛擬環境（你使用conda也可以）：
（1）克隆項目到本地
git clone [email protected]:CQUPTLei/VideoDownloader.git
（2）安裝python venv
apt install python3.12-venv
（3）創建虛擬環境
python3 -m venv downloader
（4）啟動虛擬環境
source downloader/bin/activate
（5）安裝相關函式庫
pip install yt-dlp sudo apt install python3-tk pip install prettytable# 打包用pip install pyinstaller
（6）給main.py可執行權限
sudo chmod 775 main.py
（7）執行(注意路徑)
python3 main.py
可能的修改：如果使用了從瀏覽器取得cookies文件，可能需要修改路徑，預設儲存位置可能需要修改。
Windows：
安裝pyinstaller函式庫：
pip install pyinstaller
打包指令範例，注意各個路徑，下面的程式碼是在main.py所在目錄執行的：
pyinstaller -F --paths=D:anacondaenvsvideodownloadLibsite-packages --python=D:anacondaenvsvideodownloadpythonw.exe --noconsole --icon=icon1.ico --name=Downloader main.py
Ubuntu:
一個簡單範例：
pyinstaller -F --paths=/home/moon/VideoDownloader/downloader/lib/python3.12/site-packages --python=/home/moon/VideoDownloader/downloader/bin/python312 --noconsole --icon=icon1.ico --name=Downloader main.py
MacOS:
新增對影片清單的處理和下載；
同時進行多個下載任務；
支援更多的自訂參數；

yt_dlp在pypi上沒有專門的參考手冊，github和pypi上都寫得的yt-dlp命令列程式的可用參數，但你可以閱讀yt_dlp的具體實作： YoutubeDL.py來取得可用參數和意義。
以下主要是yt_dlp.YoutubeDL(download_opts)方法支援的參數。
YoutubeDL objects accept a lot of parameters. In order not to saturatethe object constructor with arguments, it receives a dictionary ofoptions instead. These options are available through the paramsattribute fordown the Infon options. that are added to it, so this is a "mutual registration".
