  • ffmpeg not working in google colab

    16 août 2018, par Nikhil Wagh

    I’m trying to use Google Colab to do something. Particularly I want to use ffmpeg package to create a video from a image.

    But ffmpeg doesn’t seems to be working fine. Here is the link to my notebook : https://colab.research.google.com/drive/1YP-DSRoZO-Afz03tjwPfoxA-Kttm-2vK

    The output of this (in the last block) was supposed to be 400 400 instead of 0 0

    frame_width = int(cap.get(3))
    
frame_height = int(cap.get(4))
    
print frame_width, frame_height

    The same code is working fine with Azure notebooks and also on my local machine.

    What can be the reason for it ? And how to rectify that ?

  • ffmpeg using downloaded google font

    10 juin 2021, par ekato

    I am using the following code to hardsub the video and it works perfectly.

    


    ffmpeg -i "pure.mkv" -lavfi "subtitles=pure.mkv:force_style='Alignment=10,Fontsize=18'" -c:a copy "output.mkv"


    


    I would like to use a google font link, I am using the following code, but the subtitle font is still the original one.

    


    ffmpeg -i "pure.mkv" -vf "subtitles=pure.mkv:force_style='Alignment=10,Fontsize=18,fontfile="c\:\\Users\\...\\Bfont.ttf"'" -c:a copy "output.mkv"


    


    I have totally no idea what could be the problem.

    


  • Playing ffmpeg converted video on Google slides

    1er avril 2019, par user1056585

    I have a PNG image and an MP3 audio file. I’d like to create a video with a still image and use it in a Google slides presentation. From Google’s documentation, these formats (and codecs) are supported : https://support.google.com/drive/answer/2423694?hl=en&co=GENIE.Platform=Desktop

    1) FFMPEG is the easiest tool I can find to make a video from image + audio. But if you have other options, please suggest.
    2) I tried a couple commands :

    ## Command 1
    
ffmpeg -i image.png -i audio.mp3 -acodec mp3 -vcodec flv1 video9.flv
    

    
## Command 2
    
ffmpeg -i image.png -i audio.mp3 -acodec aac -vcodec mpeg4 video7.mov
    

    
## Command 3
    
ffmpeg -i image.png -i audio.mp3 -vcodec wmv1 final14.wmv

    But all of these display the error Video cannot be played in Google slides. When I try to play them in Google drive, I get the error Unable to process this video.

    Any thoughts on how I can produce a video file that’ll play in Google slides ?
