• Is there a way to use the ffmpeg binary/unix executable in a py2app application to run ffmpeg on computers without it installed ?

  4 mars 2021, par Human

  I wrote a small python script that is essentially just a text to speech script. It uses the pydub - audiosegment python library to convert the mp3 from gTTS to an ogg that can be played in pygame. A link to my github repository can be found here : https://github.com/AnupPlays/TTS

  


  this is the main function :

  


  def webscrape():
    global x
    global b
    b.state(['disabled'])
    src = "sound.mp3"
    dst = "sound.ogg"
    murl = str(url.get())
    response = requests.get(murl)
    response.raise_for_status()

    parse = bs4.BeautifulSoup(response.text, 'html.parser')
    x = str(parse.get_text())
    print(x)
    text = gTTS(x)
    text.save("sound.mp3")
    AudioSegment.from_mp3(src).export(dst, format='ogg')
    b.state(['!disabled'])


  


  this is a list of my imports :

  


  #Imports
import os
import sys
import pygame

#google text to speech
from gtts import gTTS

#requests and BeautifulSoup
import requests
import bs4

#pygame audio player
from pygame import mixer

#tkinter ui

#mp3 -> wav
from os import path
from pydub import AudioSegment


  


• Using FFmpeg within a python application : ffmpeg tool or libav* libraries ?

  5 septembre 2017, par user2457666

  I am working on a python project that uses ffmpeg as part of its core functionality. Essentially the functionality from ffmpeg that I use boils down to these two commands :

  ffmpeg -i udp:// -qscale:v 2 -vf "fps=30" sttest%04d.jpg
  
  ffmpeg -i udp:// -map data-re -codec copy -f data out.bin

  Pretty simple stuff.

  I am trying to create a self-contained program (which uses the above ffmpeg functionality) that can easily be installed on any particular system without relying on that system having the necessary dependencies, as hopefully I would package those dependencies with the program itself.

  With that in mind, would it be best to use the libav* libraries to perform this functionality from within the program ? Or would a wrapper (ffmpy) for the ffmpeg command line tool be a better option ? My current thinking on the drawbacks of each is that using the libraries may be the best practice, but it seems overly complex to have to learn how to use them (and potentially learn C, which I’ve never learned, in the process) just to do those two basic things I mentioned above. The libraries overall are a bit of a bit of a black box to me and don’t have very much documentation. But the problem with using a wrapper for ffmpeg would be that it essentially relies on calling a subprocess, which seems somewhat sloppy. Although I’m not sure why I feel so viscerally opposed to subprocesses.

• convert java code to android code [closed]

  16 avril 2013, par adityag

  I want to mix two audio files in android. First a song from library and second a sound recorded from mic.

  To begin with, I tried doing it on desktop using JS Resources Audio concat Program

  Using this code, I can mix/merge/overlap 2 sound wav files on desktop when i use float mix mode (-f).

  Now I was trying to do this in android environment. But found that javax.sound.sampled.* ; used in this code is not supported by android.

  Can anyone guide me how to deal with this situation ?

  PS : other approach i tried is trying to use some ffmpg. But frankly, I couldn't understand how to make it work to suit my requirement.
