  • ffmpeg 3.3.2 and newer native aac encoder maximum number of channels [on hold]

    21 mars 2018, par AndySP

    I’m attempting to convert a MOGG (Multi-channel OGG) audio file with 16 channels into an AAC file using FFMPEG native AAC encoder (tried version 3.3.2 and also version 86344-gb5a0971). I’m using Audacity as the source and Export -> External Application to pipe the output to FFMPEG using the command :

    ffmpeg -i - -c:a aac -b:a 240k "%f"

    Its returning "Unsupported number of channels : 16" and then failing. If I reduce the number of channels to 6 it works fine but obviously I’m not willing to remove 10 channels before exporting.

    Does anyone have an idea if its possible to get ffmpeg to accept more than 6 channels in AAC ?

  • disable post processing in YOUTUBE-DL

    9 février 2020, par user3515562

    I want to disbale post process in youtube-dl(2020.01.24).
    My batch file contains

    set /p ytlink=Enter the link of Youtube Video:-    
    
youtube-dl -x -o D:\%%(title)s.%%(ext)s %ytlink%  
    
pause  

    The youtube-dl first downloads webm file or any other file than use post process ffmpeg.exe to convert it.
    I want to disable post process.Their must be no post process happening after youtube-dl download.

    - x is the option to only download audio file of the YouTube video in webm format .There is no post processing involved.But youtube-dl by default tries to convert the webm file to some other format, which is post processing.Post processing of audio file by default is one that i want to disable

  • Calling one CLU(command line utility) with argument from another CLU in cmd ( youtube-dl from ffmpeg with additional arguments)

    3 septembre 2019, par beastboy

    I am able to run youtube-dl using command prompt , I have already kept youtube-dl.exe in the ffmpeg main folder and the ffmpeg bin folder and also I have kept ffmpeg.exe in the youtube_dl folder,

    now I am trying to call ffmpeg.exe in command prompt from youtube-dl with some additional arguments in ffmpeg and vice versa with the below commands
    and getting the following erros.

    Command

    C:\ffmpeg>youtube-dl -f 160 https://www.youtube.com/watch?v=u3APNJYMrLo --hls-prefer-ffmpeg --external-downloader ffmpeg --external-downloader-args -ss 00:00:20 -to 00:00:30

    Command

    C:\youtube_dl>youtube-dl -f 160 https://www.youtube.com/watch?v=u3APNJYMrLo --hls-prefer-ffmpeg --external-downloader ffmpeg --external-downloader-args -ss 00:00:20 -to 00:00:30

    Error

    Usage: youtube-dl [OPTIONS] URL [URL...]
    

    
youtube-dl: error: using output template conflicts with using title, video ID or auto number

    and

    Command

    ffmpeg -ss 00:00:20 -to 00:00:30 -i "$(youtube-dl -f 160 -g https://www.youtube.com/watch?v=u3APNJYMrLo)" -c copy youtube.mp4

    Error

    $(youtube-dl: No such file or directory

    Command

    ffmpeg -ss 00:00:20 -to 00:00:30 -i $(youtube-dl -f 160 -g https://www.youtube.com/watch?v=u3APNJYMrLo) -c copy youtube.mp4

    Error

    $(youtube-dl -f 160 -g https://www.youtube.com/watch?v=u3APNJYMrLo): Invalid argument

    as per my understanding and the documentation pages of youtube-dl and ffmpeg the commands should work and should download the videos in the specified resolution but its not working.
    Can someone guide me on this , what is wrong with the code and how to rectify it if any.
