• 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 :

• Fixing a corrupted .MP4 file. which might be a 3gp file

  2 juin 2020, par Tendekai Muchenje

  I have a file called input.MP4 and it is corrupted. It's from a CCTV camera. I tried everything, ffmpeg, VLC convert, no luck. However, I used mediainfo and exiftool and extracted the following info. I am wondering if someone can figure out if I can use any of this info to fix it or convert it to a usable format. I have a copy of it here on my Google Drive

  



  mediainfo gave me this :
