• Handling multiple line subtitles of Right aligned languages(arabic) in Moviepy

  24 décembre 2023, par Stanger Danger

  I am trying to add Arabic subtitles on a video using Moviepy. The issue I'm facing is related to alignment of Arabic text, as it progresses from right to left, instead of left to right in English language.

  


  

  


  As text length gets more and more, Moviepy trims the words from both ends, this issue can be resolved if we break the text into multiple lines. This works well for English language but for Arabic, the first line becomes the last line because of the (Right-Left)alignment.

  


  

  


  The text on Second line should come first on the first line at the start, while end chuck of first text towards the left corner should render on the second line, but it is getting rendered as English language, Left to right alignment.

  


  Here is my code :

  


  def add_subtitles(address_subtitles, address_video):
  video = VideoFileClip(address_video)
  generator = lambda txt: TextClip(txt, font='Arial', fontsize=22, color='black', stroke_width=2, method='caption', align='south', size=video.size)
  subtitles = SubtitlesClip(address_subtitles, generator)
  #print()

  result = CompositeVideoClip([video, subtitles.set_pos(('center','bottom'))])
  result.write_videofile("arabic_with_hardcoded_subtitles_3.mp4", fps=video.fps, temp_audiofile="temp-audio.m4a", remove_temp=True, codec="libx264"
  , audio_codec="aac")


  


• I faced ffmpeg error in my project run time

  3 juillet 2023, par Jesy J

  Runtime error: can't load audio from file: 'ffmpeg' not found. Please install 
'ffmpeg' in your system to use non- wav audio file format and make sure 'ffprobe' 
is in your path


  


  I configure ffmpeg in my system but still I face this error.

  


  This is my code :

  


  !pip install gradio
!pip install SpeechRecognition
!pip install pydub
!pip install openai

import gradio as gr
import speech_recognition as sr
from pydub import AudioSegment
import openai

# Set up OpenAI API
openai.api_key = [MASKED]

def text_to_speech(text, language):
    response = openai.Completion.create(
        engine="davinci",
        prompt=f"Translate the following English text into {language}: \"{text}\"",
        max_tokens=100,
        temperature=0.8,
        top_p=1.0,
        frequency_penalty=0.0,
        presence_penalty=0.0,
        stop=None,
        n=1,

    )
    return response.choices[0].text.strip()

# Function to recognize speech from audio
def speech_to_text(audio):
    recognizer = sr.Recognizer()
    with sr.AudioFile(audio) as source:
        audio_data = recognizer.record(source)
    return recognizer.recognize_google(audio_data)

# Function to convert audio to desired language
def convert_language(audio, target_language):
    recognized_text = speech_to_text(audio)
    translated_text = text_to_speech(recognized_text, target_language)
    return translated_text

# Function to process user input and generate output
def process_audio(input_audio, target_language):
    converted_text = convert_language(input_audio.name, target_language)
    return gr.outputs.Audio(converted_text, type="filepath")

# Set up Gradio interface
audio_input = gr.inputs.Audio(source="microphone")

language_input = gr.inputs.Dropdown(choices=["English", "French", "German"])  # Add more languages as needed

output_audio = gr.outputs.Audio(type="filepath", label="Output Audio")

title = "Multilingual AI Voice Assistant"

description = "Upload an audio file and select the target language for translation."

gr.Interface(fn=process_audio, inputs=[audio_input, language_input], outputs=output_audio, title=title, description=description).launch()


  


• Is there a method to use old versions of ffmpeg and opencv ?

  6 juin 2023, par mika_roll

  I'm trying to build a project through cmake and after some adjustements the terminal display some new errors about some libraries and I don't know how to fix them, an example :

  


  /usr/bin/ld: warning: libopencv_core.so.3.4, needed by /media/myfolder/lib/Linux64_x64/file.so.3.3, not found (try using -rpath or -rpath-link)

  


  and other errors like this one regarding libavcodec.so.57, libavformat.so.57...

  


  I've already tried to install libavcodec-dev etc and also ffmpeg and opencv by command line, and all these packages contain effectively the .so files that I need but all of them have been updated to the new version that doesn't match the one specified in the warning lines.
So is there a way to install these old versions ? Or should I try something different ? I don't really know what to do, I'm kinda new to these things so I hope I can find some help.

  


  Also, the project that I'm trying to build is not mine, someone else wrote it some time ago and my only task is to manipulate and adjust all the links to the different libraries.

  


  English is not my first language so I really hope I wrote an understandable request !
