  • Youtube-dl Python3 ERROR : audio conversion failed : No such file or directory

    21 avril 2020, par WhiteAB

    I was building a small executable, using the youtube-dl module and it is giving me the following error, and I have tried several things and nothing has worked for me

    



    import pyperclip

url=pyperclip.paste()

os.system('''youtube-dl  --no-playlist -x --prefer-ffmpeg --audio-format mp3 --audio-quality 0  '''+ url)


    



    when i try to run it does this

    



    [youtube] Ak6ynwcCv1Q: Downloading webpage
[youtube] Downloading just video Ak6ynwcCv1Q because of --no-playlist
[download] Bad Computer - Disarray [Monstercat Release]-Ak6ynwcCv1Q.webm has already been downloaded
[download] 100% of 4.49MiB
[ffmpeg] Destination: Bad Computer - Disarray [Monstercat Release]-Ak6ynwcCv1Q.mp3
ERROR: audio conversion failed: file:Bad Computer - Disarray [Monstercat Release]-Ak6ynwcCv1Q.mp3: No such file or directory


    



    I believe that I need define a path to the mp3 file but I don't know where this path should be defined

    


  • ffmpeg youtube livestream stops after a while

    15 janvier 2021, par ohroblot

    I'll update this question

    


    ffmpeg -version

    


    ffmpeg -version
ffmpeg version 4.3.1-4ubuntu1 Copyright (c) 2000-2020 the FFmpeg developers
built with gcc 10 (Ubuntu 10.2.0-9ubuntu2)


    


    I run this command to use ffmpeg to stream to youtube ;

    


    ffmpeg -y -threads 12 \
-loop 1 -framerate 30 -re \
-i ./1280x720.jpg \
-i ./audio.mp3 \
-video_size 1280x720 \
-vcodec libx264 -pix_fmt yuv420p \
-b:v 4500k -maxrate 5500k -bufsize 22000k \
-preset ultrafast -crf 23 -tune stillimage \
-b:a 128k -ar 44100 -ac 2 -acodec aac \
-filter_complex "dynaudnorm=f=150:g=15" \
-r 30 -g 60 \
-f flv rtmp://a.rtmp.youtube.com/live2/xxxx 2>&1 | tee _LOG


    


    The stream is excellent for 45-53 minutes then i'll get an error like this from ffmpeg :

    


    [flv @ 0x56077027cd80] Delay between the first packet and last packet in the muxing queue is 10034000 > 10000000: forcing output


    


    then youtube starts to say, no data being received and the stream will end, which it does.

    


    This is the full log : http://0x0.st/-zUH.txt
