    13 April 2011, by

  • avcodec/prores_aw : add support for prores 444 with alpha

    8 November 2018, by Martin Vignali
    avcodec/prores_aw : add support for prores 444 with alpha

    only 16b alpha is supported (not 8 bits)
    

    following official encoder, alpha data doesn't impact
    
yuv plane quality.
    

    So the alpha data encoding is done after the yuv part.
    
It's also avoid to loose quality in yuv part when
    
alpha is not uniform.
    

    the alpha encoding funcs is mainly take from prores_ks
    
encoder, except for the alpha data reorganization

  • MLT framework windows build melt failed to load avformat

    22 July 2015, by Philip

    I build mlt framework on windows following the official guide http://www.mltframework.org/bin/view/MLT/WindowsBuild and the solution of Error building MLT framework on Windows for the errors.

    But when I call the command melt it doesn’t work correctly. (melt noise does work)

    Using melt -query "video_codecs" I get # No video codecs - failed to load avformat consumer.

    So it cannot load ffmpeg. Is there a problem with the compilation or is something related to Windows?

  • Using ffmpeg for cutting mp3 in python -codec copy error

    2 November 2016, by Stijn Goethals
    def cut_file(file, start_time, end_time):
    
    """ Cut the mp3 file with start and end time. """
    
    output = file[:-4] + "_cut.mp3"
    
    try:
    
        os.remove(output)
    
    except Exception:
    
        pass
    
    p=Popen(["ffmpeg", "-i", file, "-c:a copy -ss", start_time, "-to", end_time, output], stdout=PIPE)
    
    p.communicate()
    
    os.remove(file)
    
    os.rename(output,file)
    
    return file

    When using this function for cutting a mp3 file I get error from ffmpeg. The error is:

    Unknown encoder ’0:07’

    Why doesn’t ffmpeg recognize the copy command when using Python? Running the command in the shell doesn’t give me any errors.

    I have tried to change the order of the arguments but this give me the same sort of errors.

    I got the code out of the official documentation.
