  • FFmpeg from Python has Corrupted Output

    14 juillet 2019, par Mazyod

    In a python script, I have :

    os.system(ff_cmd)
    
# also tried Popen(ff_cmd, shell=True).wait()

    Then, I ran that same ff_cmd from terminal directly. Here are the results :

    # ff_cmd
    
ffmpeg -i "114006.mp3" -acodec pcm_s16le -ar 16000 -ac 1 "114-006-a4dec52a.wav"
    

    
# after running from python
    
% file 114-006-a4dec52a.wav
    
114-006-a4dec52a.wav: Audio file with ID3 version 2.4.0, contains:MPEG ADTS, layer III, v2,  40 kbps, 16 kHz, Monaural
    

    
# after running from terminal
    
% file 114-006-a4dec52a.wav
    
114-006-a4dec52a.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 16000 Hz

    Can anyone please explain why in the world would they result in different outputs ?

  • How to convert video to .ico files sequence using ffmpeg ?

    3 août 2019, par marto55555

    I cannot successfully convert an .mp4 video to a sequence of .ico files.

    I tried using the same command as for converting to a sequence of .jpg/.png/.bmp files :

    ffmpeg -i video.mp4 %05d.png

    Unfortunately, when I try with :

    ffmpeg -i video.mp4 %05d.ico

    I get only a single .ico file and the following output error :

    I have also tried using the image2 muxer through -f image2. This time, the sequence will be generated. However, the images will not be actual ICO files, but JPEGs ending in .ico instead.
