  • Use FFMPEG to recover video from Ransomware

    12 mars 2021, par ParthShah

    Based on googling various articles, what I understood that the ransomwares generally encrypt initial and may be last 150 kb or so for a large files. Hence, video information of codec etc goes missing due to that but the most of the video is still available intact.
Hence, If I take a good video with same parameters of bitrate, resolution, audio codec and video codec etc, and specify this details to FFMPEG to add these details to the corrupted video, it should solve the problem. There are some programs available on the internet which does exactly the same but with paid version.
I guess FFMPEG also can do this if properly used. Anyone can help in this ?

    


  • Issue with yt-dlp and FFMPEG Converting Webm to MP4 for 360 video : Unsupported channel layout "ambisonic 1"

    22 janvier 2024, par William L W L

    I am trying to convert .webm files to mp4. These are 360 videos that have been downloaded using yt-dlp.

    


    I have been using this command successfully, but it does not work on an M2 macbook pro. It works fine on PC.

    


    ffmpeg -y -i "/Users/x/Movies/Tropical_Rainforest_360.webm" -c:v libx265 -preset fast -crf 21 -vf "scale=4096x4096:out_range=full" -pix_fmt yuvj420p -aspect 1:1 -movflags faststart "/Users/x/Movies/Tropical_Rainforest_360.mp4"


    


    The error messages are as follows :

    Context : I work in an educational setting which caters for vulnearble pupils. We cannot use Youtube in real time, this is mainly due to adverts or suggested videos that may trigger our pupils. Some children have mental health issues. Some children have also not been outdoors for several months/years due to medical conditions. We use 360 videos and VR to help bring the outside world inside, The YoutubeVR app is not an option since there is no way to install adblockers.

    


    The same script above works fine on a PC virtual machine which I can remote into from my Mac.

    


  • (WinError 2) combining video (.mp4) and audio (.mp4) using Python ffmpeg

    28 mai 2021, par Leon

    I'm new to using ffmpeg, and I'm trying to use ffmpeg to combine an audio only (.mp4 format) and a video only (also .mp4 format)

    


    I've tried reinstall FFmpeg, ffmpeg, and ffmpeg-python :

    


    import ffmpeg

def main():
    video_stream = ffmpeg.input('Video.mp4')
    audio_stream = ffmpeg.input('Audio.mp4')
    ffmpeg.output(audio_stream, video_stream, 'result.mp4').run()


if __name__ == "__main__":
    main() 


    


    It returns me this error :
