  • 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)
