  • jpg images to gif ffmpeg no data found in image

    3 juillet 2023, par Idk123

    I was trying to use ffmpeg to create a gif from jpg images, but I wasn't able to convert them, not through a python code and not even from the dir itself in cmd

    


    running cmd in the folder :

    


    python code :

    


    input_files = f"{BASE_DIR}\\qr_images\\qr%d.jpg"
command = f'ffmpeg -i {input_files} output.gif'
os.system(f'start /wait cmd /k {command}')


    


    the dir

    


    I need the files in the dir to be able to convert to gif using ffmpeg (I have it installed correctly)

    


    this is the complete cmd dialog (if I run it from the dir in cmd or if i run the python code :

  • Cannot duplicate virtual camera on Orange Pi 5B [closed]

    21 janvier 2024, par Denis Kotov

    I have faced with the issue that I cannot duplicate virtual camera for SkyDroid 5.8GHz OTG Receiver on Orange Pi 5B :

    But it also did not work ...

    


    The reason I want it, because I try to have additional processing using OpenCV but the camera is opened by another application, and it is not possible to similtuniuously open camera in 2 applications at the same time ...

    


    Have somebody faced with similar issue ?

    


  • Convert from oga to mp3 using pydub : ffmpeg returned error code : 1

    29 juin 2023, par Juan David

    I want to take an OGA file within a binary stream and convert it into mp3 using also another stream. I'm getting a permissions error even with running VSCode as administrator. This is my code :

    


    from pydub import AudioSegment
AudioSegment.converter = "C:\\ProgramData\\chocolatey\\lib\\ffmpeg\\tools\\ffmpeg\\bin\\ffmpeg.exe"

input_stream = io.BytesIO()
input_stream.seek(0) 
await new_file.download_to_memory(input_stream)
 
# Create an audio segment from the binary stream
audio = AudioSegment.from_file(input_stream, format='ogg')

# Create an output stream for the MP3 data
output_stream = io.BytesIO()

# Export the audio to MP3 using ffmpeg and write the output to the stream
audio.export(output_stream, format='mp3', codec='libmp3lame')

# Get the MP3 data from the output stream
mp3_data = output_stream.getvalue()


    


    Error message :

    I ran the command in a terminal and the file converted without an issue :

    


    ffmpeg -i .\file_12.oga output.mp3 


    


      

    1. I'm not sure if the .exe file must be included into the path. When I don't do it, What I get is a permissions error.

      2. 


    2. What other codecs can be used here ?

      3. 


    3. Is it possible to use oga files ? I tried to declare this but I got an 'Unknown input format : 'oga' message (audio = AudioSegment.from_file(input_stream, format='oga'))

      4. 


    


    Thanks !

    


    UPDATE : I created a more simple version that is not using a binary stream and worked like a charm, so we know for sure that something is happening with the BytesIO object

    


    async def voice_to_text(update: Update, context: ContextTypes.DEFAULT_TYPE) -> None:
    # Get the absolute path of the script
    filename = 'file_9.oga'
    script_dir = os.path.dirname(os.path.abspath(__file__))

    # Construct the file paths for input and output files
    input_file_path = os.path.join(script_dir, filename)
    output_file_path = os.path.join(script_dir, os.path.splitext(filename)[0] + ".mp3")

    # Load the OGA audio file
    audio = AudioSegment.from_file(input_file_path, format='ogg')

    # Export the audio to MP3 format
    audio.export(output_file_path, format='mp3')

    print("Conversion complete. MP3 file saved as:", output_file_path)


    


    UPDATE 2 : It seems like await new_file.download_to_memory(input_stream) is the problematic line. I tried to save the file and its corrupt. Not sure how to use this method then.
