How to get information from youtube-dl in python?

Question

I do APIfor youtube-dl in tkinterand pythonand should know:

• How to get dict information from youtube-dl in real time (speed, percentage completed, file size, etc.)

I tried:

import subprocess
def execute(command):
    process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE)

    # Poll process for new output until finished
    while True:
        nextline = process.stdout.readline()
        if nextline == '' and process.poll() != None:
            break
        sys.stdout.write(nextline.decode('utf-8'))
        sys.stdout.flush()

    output = process.communicate()[0]
    exitCode = process.returncode

    if (exitCode == 0):
        return output
    else:
        raise ProcessException(command, exitCode, output)

execute("youtube-dl.exe www.youtube.com/watch?v=9bZkp7q19f0 -t")

from this question

But he had to wait until the download was complete to give me information; there may be a way to get information from the youtube-dl source code.

Answer 1

Try something like this:

with YoutubeDL(youtube_dl_opts) as ydl:
      info_dict = ydl.extract_info(video, download=False)
      video_url = info_dict.get("url", None)
      video_id = info_dict.get("id", None)
      video_title = info_dict.get('title', None)

You may already understand this, but it may help someone else.

Answer 2

• subprocess; python; : youtube-dl .
• subprocess; :

/:

-q, --quiet              activates quiet mode

-s, --simulate           do not download the video and do not write anything to disk

--skip-download          do not download the video

-g, --get-url            simulate, quiet but print URL

-e, --get-title          simulate, quiet but print title

--get-thumbnail          simulate, quiet but print thumbnail URL

--get-description        simulate, quiet but print video description

--get-filename           simulate, quiet but print output filename

--get-format             simulate, quiet but print output format

3. ; , sys.output, ; :

def execute ():

    process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE)

    #Poll process for new output until it is finished

    while True:

        nextline = process.stdout.readline()

        if nextline == '' and process.poll() != None:

             break

        yield nextline 

:

for i in execute("sudo apt-get update"):
    print i
