HerokuFFMPEG后處理錯誤與yt-dlpDownloadError

我正在構建一個使用 FFMPEG 下載和播放音樂的不和諧音樂機器人。yt-dlp 似乎由于某種原因無法找到 ffmpeg 檔案，盡管我給了它直接路徑。當我在我的 cpu 上運行它時它作業得很好，但它在 heroku 中不起作用。

這是heroku中的錯誤：

這是我的設定：！[根目錄]：https ://i.stack.imgur.com/HKo8L.png

這是代碼：

yt_opts = {
        'format': 'bestaudio/best',
        'ffmpeg_location': './FFMPEG_CONFIG/ffmpeg.exe',
        'postprocessors': [{
            'key': 'FFmpegExtractAudio',
            'preferredcodec': 'mp3',
            'preferredquality': '192',
        }]
    }
# Getting Song From Thy YOUTUBE
     await channel.send("> Getting Song From Youtube")
     with yt_dlp.YoutubeDL(yt_opts) as ydl:
          ydl.download([f'{result["link"]}'])

uj5u.com熱心網友回復：

你不能這樣做：

'ffmpeg_location': './FFMPEG_CONFIG/ffmpeg.exe',

ffmpeg.exe是一個Windows二進制檔案。它不能在 Heroku 上使用（并且不應該是你存盤庫的一部分）。

大多數想ffmpeg在 Heroku 上使用的用戶都使用 buildpack（另請參閱多個 buildpacks），例如：

heroku buildpacks:set heroku/python
heroku buildpacks:add --index 1 https://github.com/FFmpeg/FFmpeg.git

然后洗掉硬編碼ffmpeg_location、提交和重新部署。您的應用程式應該找到ffmpeg.

對于本地開發，您有兩種選擇：

• 更新您的PATH以確保ffmpeg.exe可以找到
• 更新您的代碼以設定ffmpeg_location, 理想情況下來自環境變數
