  • FFMpeg conversions from avi to mp4 does not succeed with video for safari and IE browsers

    24 septembre 2020, par user27240

    The ffmpeg command below does convert mp4 file from avi file successfully for chrome browser, but with browsers such as 
safari and IE(I have not tested with other browsers yet.) I can not see the video and I only can hear the audio 
which simply means that safari and IE browsers do not accept the conversion of video from avi file to mp4 file.

    



    for i in /xxxxxx/xxxxxxx/xxxxxxx/*.avi; do ffmpeg -i "$i" -pix_fmt yuvj422p "/xxxxxx/xxxxxxx/xxxxxxx/$(basename "$i" .avi).mp4"; done    


    



    By the way, when I tried from flv file to mp4 with the same ffmpeg command both video and audio were successfully converted for chrome, safari, and IE.(I have not tested yet with others.)

    



    The avi file is the one I shot with my camera, and flv file is the one I downloaded from web.

    



    Can anyone please help me out ?

    



    The log file below is for the ffmpeg command from avi to mp4.(avi file is the one I shot with my camera)

  • Files gets corrupted after resizing with ffmpeg

    26 octobre 2018, par Liam

    I’m making a bot that sends videos to instagram. However instagram only allows 1:1 aspect ratio videos, so I’m trying to use ffmpeg in python (ffmpy module) to resize the video (.mp4) file.

    This is the ffmpeg code I’m using
    -analyzeduration 20M -probesize 20M -y -i FILE.MP4 -vf "scale=1080:1080:force_original_aspect_ratio=decrease,pad=1080:1080:(ow-iw)/2:(oh-ih)/2:white NEW_FILE.MP4

    However this corrupts the file ? The size of the file before resizing is 1.815305 MB but after the ffmpeg job it’s 0.058714 MB. So what gives ?

    (I also tried using -aspect 1:1 but that corrupts the file too)

    Ffmpy seems to work fine, because sometimes if the file is over 20 MB i run this to reduce the file size -y -i FILE.MP4 -vcodec libx264 -crf 24 NEW_FILE.MP4 and that works fine.

    Here’s the full log if needed :
