brew install ffmpeg installs python 3.9
13 novembre 2020, par mrgloomFor some reason
brew install ffmpegdownloads python 3.9 as dependence

==> Installing dependencies for ffmpeg: gnutls, python@3.9, glib, cairo, gobject-introspection, harfbuzz, libass and libvpx


As I can see here https://formulae.brew.sh/formula/ffmpeg there is no dependence on python 3.9


How can I install ffmpeg for my current python Python 3.7.7 ?


Update :


Maybe something is broken in my python installation ?


brew info python

==> Caveats
Python has been installed as
 /usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
 /usr/local/opt/python@3.9/libexec/bin

You can install Python packages with
 pip3 install <package>
They will install into the site-package directory
 /usr/local/lib/python3.9/site-packages

Regarding converting Webm to Mp4 using ffmpeg and getting problem with not receiving audio from the converted video file
14 septembre 2022, par MikeElI'm using react-ffmpeg npm package for converting the webm video format to mp4 format. Like here, this is the function which is used to convert the format.


const convertFunc = async(fileurl) => {
console.log("run");
const file = fileurl
console.log("before", file);
await FFMPEG.process(
 file,
 "-f mp4 -c:v libx264 -an -profile:v baseline -level 3.0 -movflags +faststart -hide_banner",
 function (e) {
 console.log(e);
 
 const video = e.result;
 const reader = new FileReader();
 reader.readAsDataURL(video);
 reader.onload = function (e) {

 
 console.log("Process time: ",reader.result);
 };
 console.log(video);
 }
);


}




-f mp4 -c:v libx264 -an -profile:v baseline -level 3.0 -movflags +faststart -hide_banner




this line is used for convert the format. But when I received the converted file. It is muted or there is no audio in it.
In the ffmpeg command "-an" is used to remove audio from output converted video. But when I remove it from the above command then also audio is not there.


any solution ?
Thanks for you answers in advance.
