如何在输出中获取youtube_dl的视频计数256之1

问题描述

我正在通过pyside2在Qt Creator中创建一个GUI程序，该程序可让您下载Youtube音乐。我的目标是下载播放列表时获得视频计数，例如256的x或2的x或 256的1 ，但我不知道如何。我遇到了两个问题。

我不知道如何从youtube_dl输出中获取此信息

我尝试手动获取它，但是它没有用，然后我检查了youtube_dl github下载字典键，没有一个键可以获取该视频计数 1 of 256

print("Download keys:",download.keys())
Download keys: dict_keys(['status','downloaded_bytes','total_bytes','tmpfilename','filename','eta','speed','elapsed','_eta_str','_percent_str','_speed_str','_total_bytes_str'])

工作线程中的Youtube_dl代码：

def run(self):
    self.main_window.progressBar.setValue(0)

    self.ydl_opts = {
        'format': 'bestaudio/best','noplaylist': self.main_window.playlist,'source_address': '0.0.0.0','ignoreerrors': True,'progress_hooks': [self.my_hook],'postprocessors': [{
            'key': 'FFmpegExtractAudio','preferredcodec': 'mp3'
        }]
    }

    with youtube_dl.YoutubedL(self.ydl_opts) as ydl:
        ydl.download([f'{self.main_window.downloadURL.text()}'])

def my_hook(self,download):
    if download["status"] == "finished":
        print("Finished")
        self.main_window.progresstext.setText("Ready")
    if download["status"] == "downloading":
        self.updateText.emit("Downloading...")
        percent = download["_percent_str"]
        percent = percent.replace("%","")
        self.updateProgress.emit(float(percent))
