  • Error in FFMpeg and png images (glob/libavformat) [closed]

    1 June 2013, by Alain P. Francés

    I'm trying to use FFMpeg to produce an animation based on several png images
    that don't follow a sequence number. With
    the following command line

    ffmpeg -f image2 -r 1 -pattern_type glob -i '*.png' -c:v libx264 mov.mp4

    I obtain the following error

  • ffmpeg convert images to mp4 error

    31 May 2013, by Ryan Saxe

    So I have a script that grabs a bunch of images from the web and then converts them into a movie. Yet I get a whole bunch of errors when I run it.

    First let me show what I am running and then I will post the error because it's huge:

    #for gif
    #call('convert -set delay 5 -loop 0 ' + folder + '*.jpg ' + name + '.gif', shell=True)
    #for mov
    #call('convert -quality 100 ' + folder + '*.jpg ' + name + '.mov', shell=True)
    #for organized movie
    call('ffmpeg -r 10 -b 1800 -i ' + folder + '%0' + str(size) + 'd.jpg ' + name + '.mp4', shell=True)

    So the commented out versions work fine, but I need to use the 3rd version! Here is the response I get from ffmpeg:

    repeated about 30 times, but i cut it out of the traceback because it was overwhelming.

    Question: What did I do wrong and how do I fix it?

    Edit:

    I download the jpeg files using the urllib python library's urlretrieve. This is how I save them:

    for src,name in zip(urls,range(len(urls))):
       file_name = folder + str(name) + '.jpg'
       urlretrieve(src, file_name)
  • lavfi/mp/mcdeint: avoid uninited data read

    31 May 2013, by Stefano Sabatini
    lavfi/mp/mcdeint: avoid uninited data read
    

    Do not read padding or out-of-buffer values when computing the output
    value for a pixel close to the image buffer edge.

    This avoids non visible artifacts which affected the output checksum.

    See thread:
