  • Invalid image height when converting a specific (seemingly valid) GIF to an mp4

    3 février 2020, par joe

    I’ve come across a weird GIF file on the internet that ffmpeg doesn’t seem to like. Try running the following commands :

    curl http://images6.fanpop.com/image/photos/34300000/Klaus-The-Originals-klaus-34349255-120-113.gif > input.gif
    
ffmpeg -y -i input.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" output.mp4

    I get the following output with ffmpeg version 3.4.6 and 4.1.3 :

    I’m a newbie with ffmpeg, but as far as I understand, the -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" scales the image so that it height and width are even numbers (needed for mp4 file format), so that should prevent this sort of error from occurring ?

    This looks very similar to this issue over at trac.ffmpeg.org, which has apparently been fixed.

  • Read a Bytes image from Amazon Kinesis output in python

    14 février 2020, par Varun_Rathinam

    I used imageio.get_reader(BytesIO(a),  'ffmpeg') to load a bytes image and save it as normal image.

    But the below error throws when I read the image using imageio.get_reader(BytesIO(a),  'ffmpeg')

    The above approach to read a MKV bytes file was done based on this thread

    Or is there is any approach to parse and read the MKV bytes file.
