I am trying to download a youtube livestream that is always up, but broadcast the important content at a certain time of the day. When I start the download I want to use the information from stdout for setting when to stop the download with a CTRL+C Signal.

This is the segment I am interested on:

frame=  299 fps=4.7 q=-1.0 Lsize=     387kB time=00:00:10.00 bitrate= 316.9kbits/s speed=0.159x

My problem is, that I can't find where to get this string when downloading. The logger doesn't receive all stdout.

I am using the example python embedded code.

from __future__ import unicode_literals
import youtube_dl


class MyLogger(object):

    def debug(self, msg):
        with open("debug.txt", "a") as text_file:
            text_file.write(msg)

    def warning(self, msg):
        with open("warning.txt", "a") as text_file:
            text_file.write(msg)

    def error(self, msg):
        with open("error.txt", "a") as text_file:
            text_file.write(msg)


def my_hook(d):
    if d['status'] == 'finished':
        print('Done downloading, now converting ...')

ydl_opts = {
    'format': 'bestvideo+bestaudio/best',
    'noplaylist' : True,
    'logger': MyLogger(),
    'progress_hooks': [my_hook],
}

stream_url="https://www.youtube.com/watch?v=05K00cYTFO8"
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ydl.download([stream_url])

I solved it by using only the command line and not the python api

ffmpeg -i $(youtube-dl -f best -g "$URL") -c:v copy -c:a aac -strict experimental -t 00:45:00 $VID_NAME.mp4
