  • How can I know a certain file is a video file ?

    31 mai 2019, par Arthur Park

    I am trying to figure out if a certain user-uploaded file is a video file.

    I first tried ffprobe,

    # a png file
    

    
Input #0, png_pipe, from '<file>':
    
  Duration: N/A, bitrate: N/A
    
    Stream #0:0: Video: png, rgba(pc), 920x2094 [SAR 4724:4724 DAR 460:1047], 25 tbr, 25 tbn, 25 tbc
    

    
# a text file
    

    
Input #0, tty, from '<file>':
    
  Duration: 00:00:00.24, bitrate: 40 kb/s
    
    Stream #0:0: Video: ansi, pal8, 640x400, 25 fps, 25 tbr, 25 tbn, 25 tbc
    

    
# a video file
    

    
Input #0, matroska,webm, from '<file>':
    
  Metadata:
    
    encoder         : libebml v1.3.5 + libmatroska v1.4.8
    
    creation_time   : 2017-12-12T20:18:42.000000Z
    
  <redacted>
    
</redacted></file></file></file>

    but it’s too hard to figure out what’s what. Even image files and text files count as a video.

    Should I compare the output matroska,webm, with every codec ffmpeg supports or is there a better way to do this ?

  • FFmpeg file path exception like file name not found

    7 février 2018, par Sagar Hudge

    I am getting following exception on video trimming.

    video path : /storage/emulated/0/Pictures/Instagram/Fast &amp; Furious 7 - Get Low Extended Version Video.mp4

    file name : Fast &amp; Furious 7 - Get Low Extended Version Video.mp4

    and ffmpeg searching for only Fast in

    /storage/emulated/0/Pictures/Instagram/Fast: No such file or directory

    I have found the issue ,it is causing due to the file name having spaces in between them you can check in above mentioned path and in exception.

    after changing file name its working but changing name of every file from device its not the right way so how can I solve this exception

  • FFmpeg could not read existing .bmp frame sequence to make .avi file ; What is wrong ?

    13 mai 2017, par xakepp35

    Assume current directory contains files in .bmp format, named IMG_0000.bmp, IMG_0001.bmp, and so on. I need to make avi file from them, threating them as a frames. FFmpeg gives me an error, and i could not understand what is wrong. I’ve got following error message :
