Hello everybody,

Since some days, I am working on a project for my internship which is about extracting audio from a big list (.csv) of Youtube videos. We have chosen to use YouTube-dl library in python, which seems to be powerful .

I have found many explanations about Youtube-dl in command line, but I am interested in a program using this library.

1. Does a documentation about equivalence between command line and embedded youtube-dl exist ?

2. We would like to obtain a bunch of audio files with the same features for all of them. I achieved to extract only the audio and to chose the extension (.wav). However, I would like to have all my files with the same sample rate (44.1kHz). I have seen that, in command line, I can use '-f bestaudio[asr=44100]'. But how can I do that in a python program ? Is it possible ?

3. I didn't see anything about mono or stereo file. I would like to extract my audio files in mono. Do I have to use another tool ? Or is a feature like that existing or will exist ?

Thank you in advance for your help !

2. I achieved to do something. Here is the line to put in the options : 'format': 'bestaudio[asr=44100]/best'
   But, if the asr wanted is not available, there is no error : it is just not taken into account.

3. You'll need to do conversion yourself.
