巴哈自動排版太過死板，把我格式都吃光，所以程式碼顏色都不見了
要怪就怪巴哈

更新了程式碼讓程式又可以運作，YT又改規則沒辦法
最近想到如果是下載演唱會之類的
那在結束直播時會可以下載，公開時間短暫，變為私人影片
改為私人就無法獲取下載網址
下載時改為私人後，也會遇到聲音抓不到影片網址，下載不到聲音檔的問題
也許考慮在下載影片時先把聲音網址存起來，再執行下載影片
下載聲音時再把儲存的網址來出來下載，應該可以順利下載到聲音供合併
不過有空再說了...

今天又試了一次短影片
可以正常下載，之前明明不行的，看來YT把短影片弄得跟一般影片一樣了
目前沒有對應短影片，最近忙其他事情，沒空也沒心情弄這個

已經完成webm下載合併的部分
幾乎沒有需要再加強的地方了
除了 youtube定時更新阻擋模組使用需要更新
google是真的很勤勞，約一個禮拜就會改一點東西，讓你原本模組不能使用
2022/01/28 更新
目前更新了解析度識別出webm功能
按鈕的部分增加對選擇BOX的繫結
程式的操作如下：
這是初版，內容大多底定了
新的有加上一些文字，錯誤捕捉等等
已知問題，這是針對抓取mp4設計
有些影片高畫質mp4檔最高只到1080p，有些2K影片只提供webm檔
如果要支援webm可能還要大幅擴充程式碼加上專門處理webm的部分
想到就頭痛 QQ ，所以可能會做也可能不做，畢竟mp4就很夠用了
做這個程式時發現的小知識，YT高畫質都是漸進式下載，也就是看一段載入一段，不會一次下載完
但720p幾乎都是自適應下載，也就是一次載完讓你慢慢看，所以如果不想要一直緩衝的話
選擇720p等他載完慢慢看就好
姑且放個執行檔供下載使用，使用 pyinstaller打包本體10MB
ffmpeg執行檔佔了其他空間
內容有執行檔與 ffmpeg(合併影片與音訊用)，ffmpeg.exe可自己放更新的版本
預設下載位址是根目錄的download資料夾
使用會被微軟防毒擋，大概是使用呼叫控制臺合併影音的指令被認為有害
程式碼都在下方，有沒有毒自己斟酌吧
